If you are going to cry "wolf", at least do it with the right words. Rotax released a "Service Bulletin", SB-912-056 UL and SB-912-056. As stated earlier, you can get the SB at the Rotax Owners website or you can get it straight from Rotax at: http://www.rotax-aircraft-engines.com/pdf/dokus/d04129.pdf I prefer to use the factory site for all my documentation.

Reporting in on the Repairman / E-LSA process: Completed the EAA SportAir Workshop course at Oshkosh this weekend. Learned a lot and scored 98% on the test (I did not know where cables are most likely to break) Now I need to present my application at the FSDO and I am all set. 16 Hours of class and lab, 50 question exam, and 16 E-LSA owners in the class. It was a fun time as well as educational. There was one other Kolb drive from Omaha there too. He has never heard of the Kolb List, but it is understandable because he does not use the Internet either..... yikes. The class encouraged him to get on-line and get networking.

No "wolf", but a fact and and a slip of the tongue. Being accused of "crying wolf" is a little harsh when some one wants to help people. After I heard Rotax state what the compliance was on AD's, SB's ,SI's and SL's I was along with others dumbfounded that usually only 20%-50% comply. Anything above 25% is a lot they said. Most don't even bother to send in a warranty card for their engine. So my intention was to try and help those who would like it done or who might not have heard about the Gearbox SB. Rotax flips the bill. -------- Roger Lee Tucson, Az.

Subject: Landing lights
Scott, I used car fog lights. I am usually out of the air before it is dark enough for them to be of any help landing. However, I do turn them on when I enter the pattern so I am more visible. My pilot buddies say they look nice. I also flash them at other GA aircraft that are coming head on at me, to make sure they see me. They were worth it in my opinion, however the main reason I put them in the FSII, is I needed more weight in the nose of the airplane. I figured that every ounce helped.

Roger, Pennzoil CHANGED THE NAME(and thus the label) of the 2-stroke oil for air cooled engines to something with "outdoor" in it. They DO NOT have a single oil formulation being currently sold with two different names! Your statement that they are simply relabeling is misleading. Also, the 912ul engine compression ratio is 9.0:1 not 8.5:1. Thom in Buffalo ________________________________________________________________________________

They changed the name of the "air cooled 2-stroke" oil to "outdoor", but the "watercooled" product is/was something different. Whether it's _really_ anything different I don't know, but it would make sense that the formulation would be different for an outboard engine running at lower temperatures (cooled as it is by a steady supply of cold water) as opposed to an aircooled engine running at higher temperatures. Either way, I would think that the air cooled ("outdoor") oil would be a better choice for a water cooled Rotax since the operating conditions are closer to those of an air cooled engine than an outboard. When you think about it, a watercooled Rotax on a plane IS air cooled... just indirectly. -Dana -- Scientists cause cancer in laboratory animals. ________________________________________________________________________________

Start with a copy of FAA form 8050-1 from your local FSDO. Ask them if you need to fill out the 8050-1 or 8050-2. Then call the local MIDO office and have them send you the Amateur Registration packet for free. Find the local DAR in your area to help you through the process. Basically, it's easy to fill out the 8050 form, but you need to fill it out properly or the FAA will reject it and the process will take a long time. EAA does have an Amateur-Built packet that can lead you through the steps too for $12.99. Don't confuse it with the E-LSA packet, as that deadline expired on 1-31-08. There is no deadline for E-AB registration. -------- Ralph B Original Firestar N91493 E-AB 21 years flying it Read this topic online here: http://forums.matronics.com/viewtopic.php?p=168755#168755 ________________________________________________________________________________

<< I am an authorized and certified Rotax service center. Roger Lee Tucson, Az >> Roger - Nice to know. Thanks for passing on the info to this List. It amazes me to see how slow the FBO industry is to ramp up to becoming "authorized" service centers for Rotax engines, especially with the new wave of Light Sport Aircraft being delivered, where nine out of ten of 'em use the 912. At last count, I think there are barely a dozen authorized Rotax service centers serving the US. Last summer, when I called the aircraft repair shop at one of our local airports to ask them if they were qualified to work on a Rotax engine, the mechanic asked, "What's that - a go-cart engine?" (Sheesh!) It would be nice if I could take my 912 to a local airport FBO if I ever needed any heavy service, rather than 1000 miles away. Roger's shop in Tucson is "only" 450 miles from where I live - a much better option for me!

Hi Dave, Unfortunately Rotax looks at each case separately. If it is a safety issue then probably yes. If it is just a change then it might or might not be. You will need to call a Rotax distributor on your specific issue. Sorry, probably not the answer you were looking for. Hopefully a nice distributor will do it for you. Never hurts to ask. -------- Roger Lee Tucson, Az.

Hi Dennis, Anytime you need something let me know if I can help. I feel the same way as there are not enough LSA specific services available. That's one of the reasons I started to take all the schooling I could over the last few years. I retired from the fire department so now I have lots of time on my hands to learn. I have people fly in from TX, NM, CO, UT, NV and CA for work. For some I fly in with my plane and another pilot sometimes and ferry the other persons plane back to Tucson if need be. I have a CT to ferry over from El Paso area next week for a gear set change out. (5 gear sets in the next 2 weeks) I hope I can continue to offer people quick reliable service. I don't come close to claim I know it all, but I continually go to schools trying to learn more. I couldn't find a person to do dynamic prop balance's either so now I do those as well. That was an OUCH for the equipment, $4K. I'm trying to specialize in LSA and experimental service work. I have been contacted by some of the LSA MFG's to do their service work in this area. I'm getting ready to fly up to Albuquerque soon for fun and to have lunch with a few LSA & CT guys. I let you know if you would like to join us. -------- Roger Lee Tucson, Az.

Hi John, Normally yes I could, but he needs his engine mounts changed out (rotted) and that's about 2-3 hours and you have to use an engine lift to slide the engine forward about 8". I will also do a dynamic balance for him while it is here. (He's 82 years old and would rather I come get it.) I just make a breakfast run out of it. It takes me roughly 2.3 hours to fly there. I'm a customer service type of person. The other 4 guys that need gear set change outs need other work done, too. A CT and a few of the other LSA's takes me about 2 hours from start to stop (that's ready to fly) to do a gear set change. Most guys seem to want the quick turn around and less down time than to send it in and have the shipping delay flight time. They just make a fun trip out of it. I would prefer my shop just in case I need any extra tools and I have a nice hydraulic press to make my life easy to do the gear set. Kind of like the home court advantage. -------- Roger Lee Tucson, Az.

I just bought an Aerosun 1600 LED landing light for installation on my titan. The landing lights I have draw way too much power and I want something brighter closer to the ground. It's going under the nose in front of the nosewheel as soon as I can get the preliminary wiring stuff out of the way. with 8 LED's it's at least as bright as a big halogen general aviation landing light, maybe more judging by hooking it up to a car battery. But the current draw is tiny at about 2 amps....... It's pricey but I really need a good low-current light that's bright as the jeepers.... I'll let ya'll know how it works out once I get it installed on the plane....

The TCW-III grade is primarily a standard for lubricating water-cooled 2 strokes. API TC grade is a tougher standard intended for lubing air-cooled motors. The TCW-III spec does specify a miniimum lubrication ability for air-cooled engines, tho, so it will work fine in an air-cooled engine as well. It's not as stringent as the TC spec tho...

The spades are an interesting idea. Has anyone tried extending the ailerons outboard and forward of the wing tips like on some of the old biplanes?

My ailerons get " Springy " due to the long torque tubes on the trailing edge of the wing that actuate them twisting under flight loads.

Anyway my question is this. Would someone who has a MKIII extra on a car carrier measure the distance from ground to highest part of plane so I can ensure proper door height. My plan is to have two doors one at each end of the garage so I can drive through and drop off. Anyway if building this Kolb has taught me anything is measure, measure, measure, then cut.

Subject: ANR Headset Upgrade
Date: Mar 11, 2008
I had planned to have an ANR headset for this summer but hated to pay the price. I had decided to do the upgrade, that some have discussed recently, to my passive headset. While looking for some hearing protection for a problem area at work I ran across a set of ANR ear muffs for use in industrial environments and they even had a 3.5mm audio input jack. Wow only needs a mic. Specs. are 26db NRR passive and 20 db NRR active in the 100 to 200 hz range. The ANR range is 20 to 1000 but is rated at 20 db from 100 to 200 hz. The UPS truck dropped off a package today and I went to work. I mounted the mic from an old headset to the battery cover which required drilling one hole. I also made a piece from 0.050 aluminum to stiffen the location where I was mounting the mic. Everything works well but I have not tested it in flight yet. I will give a report after some in-flight testing, maybe this weekend. Did I mention they were $149. I have attached a link to the website. I bought them from an online store called Active Forever, They had them in stock. Hope to fly this weekend.

Hi Lar, To refresh your memory, I'm a long time back acquaintance from Kolb life -- and we actually met at Castle AFB once. Congrats on retirement. Open road and a boat -- not bad! Sad to hear Vamoose will be going elsewhere, but then there is freedom in moving on too. Besides just wanting to say hey, I have some curiosity about Vamoose's engine. The engine subject comes up periodically on the Murphy list. Several guys there have put on 912S engines and love them, but the price of course has risen beyond crazy, I believe ~20k low-value US dollars now. Non-Murphy folks are often surprised that a 912 powered Murphy can be built to 725 lbs empty, and they work real well with 100hp and less weight on the nose. So, how much power -- max and sustained -- do you figure is available from Vamoose's engine (and at what rpm)? BTW I recently checked out your photos from touring BC.

Ben I'm going to jump in here. We talked years ago about VWs and BMWs. I choose to use the VW and have been flying VWs on my MKIIIC for six years. First it isn't HP that moves a airplane it is thrust. Redrive VWs can be configured to the same thrust as a 80 HP Rotax and will survive running with a 80 HP Rotax quite well. Lars engine is a bore slightly smaller than mine 90.5mm vs my 92mm. His plan was to run alot higher RPMs than I do so the HP and maybe the thrust would be more like the 100HP rotax or maybe more. The problems Lar was likely to run into would be getting rid of the heat at the higher power and reduced reliability. You are aware Lars engine is a redrive engine not a direct drive engine. You reference Murphy airplanes (we are on the Kolb list) which are tractor engine airplanes. Tractor mounted redrive VWs run smoother and cooler. Cooler due to the big fan out front. Smoother because the prop runs in clean air. The biggest improvement in thrust you can get would be using a large two bladed prop with a big reduction ratio. The group that built a squadron of WWI replica airplanes use a 8 ft prop with something like a 2 to one or more ratio. My understanding is that they get performance close to what a engine with twice HP would be, direct drive or maybe even a Rotax with a standard ratio redrive. Talk to the guys a Valley engineering/Culver Props. Be aware that a VW isn't going to weigh less than a Rotax. Also the original engine was designed as a 36 HP so the more you ask of it the less reliable it will be. Personally 100 HP seems like too much but????

Subject: Re: Vamoose for Sale
Thanks, Ben. I do remember meeting you at Castle. That were a good air show, and a reasonable location for a SoCal resident. (at the time) After a lot of research, I figured on Vamoose' 2110cc engine to have around 140 hp at 4800 rpm and 90 hp sustained at 3800 rpm. These numbers were pretty well documented in several VW hotrod magazines at the time I built the engine. Later experience in my 2110cc Baja Bug tells me that Rick is probably correct about reliability at the higher number. That engine is really howling at 4800 and I doubt I'd want to sustain it, but my purpose there was for emergency power and it seems that it was certainly there. On the 1st test run, Vamoose slammed a 550# scale against the stops seemingly effortlessly......before it twisted the input shaft off the redrive. It was impressive, exciting, and fun, sitting in the pilot's seat. With fuel injection, electronic ignition, higher compression (figuring on using avgas) and an aggressive cam, it makes Der Bug's engine seem calm and quiet in comparison. The thing is brutal. Again, going by Der Bug, (which 2110cc engine is less highly tuned) 3800 rpm is a walk. Effortless, and is really into the power band. 65 mph is around 4,000 rpm, and it'll hum along all day. Der Bug has many 1,000's of miles now, of off road, freeway cruising and general zooming around town and has been *almost* totally dependable. Breakdowns have been things like clutch cable, gas cable, clutch linkage, etc., but the engine has been flawless. It gets driven hard, almost all the time. The thing is so much fun it's hard not to tromp on the go pedal. I'm pleased that you enjoyed my web pages, and that you took the time to look. I'm disappointed that so few have. The British Columbia coast is spectacular, the experiences were certainly fun, and I enjoy seeing others enjoy them, too. I've been in New Mexico for 16 months now, (already ! ! ! ) and have been busy most weekends. Some are documented in the blog in my signature, below. I well remember your pictures of sandbar hopping and freighter strafing and was very envious at the time. You obviously enjoy your toys, too. Lar.

Very handy to have, for securing hose lines, all sorts of stuff. http://www.clamptitetools.com/Instructions.html Mike Welch _________________________________________________________________ Climb to the top of the charts!Play the word scramble challenge with star power. http://club.live.com/star_shuffle.aspx?icid=starshuffle_wlmailtextlink_jan ________________________________________________________________________________

You can see how much thicker the tube is on the new part. I am not sue how I will relocate the drilled holes on the new part to match the gear leg.

Do you know what a rivet locator is? It is used to locate a hole in the top skin when laid over a hole in a lower surface... how to make one... take a 8 inch piece of sheet metal and fold it in half. Then drill a hole through the ends where they overlap... place a rivet through the lower piece and insert the rivet in the under lying hole, then putting the piece of skin you want to locate the hole in, between the folded over halves of the locator, the hole in the top of the locator will locate the hole in the skin. With that mental picture in mind,,,, take a piece of sheet metal, and clamp it to the leg a few inches above the axel fitting using a screw clamp, or two to keep it from moving.... drill the sheet metal from the opposite side of the gear leg through the existing hole. This will locate the hole... then pull the sheet metal far enough from the leg to slide the axel fitting on,, make sure you don't move the locator, when the axel fitting is properly aligned,, the hole in the piece of sheet metal will locate the hole in the axel fitting.

Joe, Welcome to the list. congrats on your new Kolb . The biggest difference between your Kolb and what you are used to, is it has more drag and slows down quickly. You dont want to flare it until you are close to the ground. The closer the better. Actually you hardly flare at all. Just fly it to about a foot off the ground and back of the throttle. If you flare like a conventional craft you are asking for trouble. Good Luck, Ed Diebel ( Firefly 62 In Houston) 80* today **************It's Tax Time!

Boyd Ok I am going one step further after sleeping on this. In order that you don't increase the size of hole in the gear leg, make a snug fitting bushing and slide it in the gear leg hole.. Now when you drill the sheet metal to mark the hole location in the gear socket. use the largest drill that will fit inside the bushing, using it as a guide. Slide the axel fitting on the leg and align the fitting and drill with the smaller size drill.. after drilling you will be able to check the alignment by putting the drill bit through the hole in the axel fitting and into the bushing.. if the alignment is ok then go ahead and drill it to the proper size,,, if it was off a bit,,, then file the hole in the axel fitting to correct the alignment,,, then drill through to the other side of the axel fitting, then from the other side open it up to the correct size, remove the bushing, and continue drilling through the first hole to correct any offset. You may have to read a bit between the lines.. But this will give you a trial fit and a chance to correct it before drilling to the full size.

Date: Mar 16, 2008
I'm looking for advice on tailoring my new FireFly. I'm going to bring it home to PA from TN in the near future, and although I have numerous pictures and sites about tailoring a Kolb, I'd like some specific advice from those who have done it successfully. As a starting point, I have thousands of miles hauling machinery loads on 18 wheeler flatbeds and lowboys with overweight and over-dimension loads a normal challenge. But the only Kolb I hauled was my US on my half ton pickup, wings and engine in one load, and the rest on another. I made ramps from the ground onto the front of the pickup and pulled it onto the truck so the mains rode on the cowl right by the windshield (I had the landing gear crossmembers Xing in front of the windshield) and the boom tube continued from above the cab back to the tailgate, suspended by a simple bungee rig. Looked kind of like the space shuttle riding piggyback on the huge cargo jet when they move it. And this was only for a distance of about 30 miles. I bought a field construction trailer which is ready for the trailer park in the sky to both haul and hanger my new Kolb. It has an overhead door in the rear and is 28' long inside, 32' overall. I am going to gut the entire interior and re-work the overhead door from rolling at the header to sliding along the top for more height. I doubt if I'll throw truckers chains over the FireFly and bind it down with chain binders, so, folks, any tips (that may not be apparent in the pictures available) you can give me on tying it down, cradling the tail section and protecting the fantastic paint job would be greatly appreciated. I really, REALLY don't want to scuff the FlagFly.

Joe As Ed has suggested your biggest problem is landing. Your experience will serve you poorly. On your first landings keep the power maybe on 25% till you are within less than a foot of the ground. Then and only then cut the power. Also don't use flaps at all. As you get more experience SLOWLY reduce the power you set for approach or set one notch of flap. Don't do both at the same time. In fact you may be better off adding a bit more power the first time you use one notch of flaps. Some of us still carry some power with lots of experience. I like to carry some power because landing with one notch of flaps with some power will feel just like no power (engine out) with no flaps. I know this first hand. Some of us never use full flaps other than for brief periods on approach to hit the landing point you want. There is one of our members that uses full flaps and power off on all his landings but I would wait for that after your first thousand landings and even then approach it with added power. There will be those that will tell you I'm being too conservative but most GA pilots will have problems if they move too fast to flaps and no power.

How you specifically address them will vary based on the trailer, the plane and most importantly what makes you feel comfortable. -Get the weight off the tail wheel. Most popular method seems to be suspending the boom tube in a cradle secured to the floor. This method accomplishes the primary objective and keeps the tail in place. Others use a sling, suspended from the ceiling to set the boom tube in. This method requires more thought in preventing the tail from swaying side to side. -Get the weight of the wings off the boom tube. Some build cradles for the wings, securing the cradles to the floor. Others use slings and suspend the wings from the ceiling. Either way, the wings need to be stabilized to keep them from banging into anything/each other. Some leave the wings in the normal folded position and use slings to relieve the weight of the wings from the appliance that attaches the wings to the boom tube. Finally, some take the wings off entirely and secure them to the walls of the trailer. Still requires cradles or at least padding. -Secure the mains to the floor. Blocks/chocks on all four sides of each wheel and then strap the wheels/axles to the floor. There are differing views about securing the cage itself to the trailer. Those that say "don't do it", offer that the mains should be able to take anything that you would encounter while trailering plus rigidly securing the cage puts unnatural stresses on it. I tend to go along with this view. The section on Trailering a Kolb on my web site has examples of all these methods. Hopefully, this will help and others will offer views as well. Bottom line is you have to be comfortable with the method you choose. My $.02 worth which got me 1250 miles from Northern NJ to SW FL. Good luck with your new toy.

Hi Folks: Chow out the little mkIII and flew up to the factory last Wed. Wonderful flight. Logged 4.1 hours on the way north. Friday morning headed south, made it 7 sm from Rockwood, TN, ran into a brick wall, turned around and flew back to TNK. Rain, low viz down and back. Flew 173.2 sm, 2.2 hours, and ended up back at TNK. Yesterday morning I departed TNK. Weather looked great all the way to Rockwood, TN,90.0 sm and 1.1 hours later. I could see the dark clouds to the west when I made my approach to KRKW. I elected to stay at KRKW until 0900 this morning. Was a great decision. Got lots of rest. Spent the night on the front porch of the FBO. Wouldn't let me sleep inside. Some FBO's are not designed for "barn stormers" and some are. This morning I flew .6 hrs and 66.2 sm to Collegedale, TN. They had a full coffee pot, sandwiches in the frig, and a cheese Danish. Had fun talking to the local pilots, then headed SW for Gantt IAP, Alabama. Arrived 2.1 hours and 184.0 sm later. Was good to be home. Weather was perfect today. Had a good tailwind. My ground speed was between 95 and 116 mph all the way home. The little mkIII did great, as usual. Was a good training flight to get ready for the flying season. Sun and Fun next month and Monument Valley, Utah, in May. John Bickham's flyin in July, and also Oshkosh. Then the Kolb Homecoming the end of September. My, my! Time is flying when we are having fun. Take care, john h mkIII ________________________________________________________________________________

Boyd: I have one of those hole locater devices you describe. I get the idea of using the strap on the outside. I was looking at the part and I am thinking I may be able to set up the old with the new and get the position located OK and put it in my drill vise and put the hole through both sides. If the alignment is off with the existing hole on the gear leg I can clamp it in place and drill through the next larger hole. I would not even be messing with this if Larry had not broken his. But, if I can minimize the opportunity to bend my plane, it is a good thing. Besides, it is still cold here and I cant fly it anyway. I have some handy tools to locate the centers of holes but they do not work here. I have a phone call to make to another Kolber with a suggestion to consider too.

Many owners retrofit a single strut with a bar at the top to span both attach fittings on the wing. -Dana -- Computer games don't affect kids, I mean if Pacman affected us as kids, we'd all be running around in darkened rooms, munching pills, and listening to repetitive music. ________________________________________________________________________________

Subject: Takeoff & landing & stall help
From: "grantr" <grant_richardson25(at)yahoo.com>

My instructor and I are learning how to fly my MKIII! Flying it is not hard taking off is a bit tricky for both of us. Landing he does good. I do fair. He has over 2000hrs in phantoms and Challengers. He currently flies a challenger II. We are still getting used to the plane and have a few questions for you experienced kolb guys. Today I almost took out a runway light on takeoff. My instructor is pretty sure we were hit by a cross wind gust just after I raised the tail. Anyway the plane made a hard veer to the right when the tail came up then I over corrected and made it veer left and then It really went right back into the wind and off the side of the runway. We got off the ground in time. my plane stalls at 45mph indicated We are raising the tail at about 40 to 45mph and rotating at 55mph. Climb at 60 to 65mph. These seem to be good numbers. How do your numbers compare? Do you guys have the VNE speed for the MKIII and the max flap speed ? What is the best way to make a crosswind take off on asphalt or grass? Is it ok to hold the tail on the ground until rotation speed? Landings: We approach at 65 mph engine idle We are making the landing at idle and using power as necessary on the approach. 65 mph give plenty of energy for a nice touch down. We have not experience the So called kolb drop. The only drop was my high flair. :D I am having a hard time judging when to round out. I want to round out fairly close to the ground and my instructor gets nervous and is telling me to round out higher. he says if I miss it by a second we are going to hit the ground hard or fly right into the ground and kill us. We are having radio trouble too. Since we cant communicate he just doesn't know if I am going to round out or not. He has military headsets and 1 GA headset. I have comtronic which is not compatable. I bought a cord thats suppose to adapt the GA headset to my comtronics. The head set works but the GA mic doesnt work. Does anyone have a used mic for a good price that might work or a comtronic headset with mic? His landings are good. The one I tried a little higher involved dropping the plane fairly hard and bouncing 3 times! Those gear legs are tough! I made the last landing of the day and it was a perfect power off landing. I really don't know what I did different. Stalls: Is it normal for the MK III to give very little to no warning of an oncoming power off stall? There is really no waring signs. the plane breaks at 45mph. With power on the disrupted airflow over the wing spills into the prop making a lot of prop noise but this is about 1 second before the plane stalls which doesn't give much warning.

Group, I have had a question about the safety of the Firefly in windy conditions. Anyone have a fair amount in a Firefly AND a Firestar? Just pondering the differences. The Firestar weighs more but it also has more wing area. Anyone know which one has the highest wing loading. Lastly, If a Firestar and a Firefly were being flown cross country would a Firefly be more vulnerable if the wind got a little brisk, or would they both behave about the same.

Because the dreaded Kolb drop, or stall is what it used to be called occurs a little later and a little slower which gives the pilot a little more tim e to make adjustments in the landing environment.

Hi All, Well I got the prop hub extension on and tried it today. It made a noticeable difference in the cockpit noise. I took my Db meter with me and measured about a 3 to 4 db noise reduction in the cockpit area. I also noticed the aileron torque tube on the right wing panel did not vibrate nearly as much as before. Overall Id say that the extension of 3" did help significantly with the noise I was experiencing and reduced propeller tip pressure induced vibration to the airframe. The propeller is now at about 5" from the aileron torque tubes and this seems to be the magic number. I would recommend this modification for anyone considering it.

I will add my two bobs worth here on how I do it. Two up long finals ,60mph at about 300 to 500 agl depending on where the runway is, reduce speed to 55mph and full flap . Use the throttle/side slip to put yourself on the spot you have picked to touch down. Most times from 300 ft there is no need to touch the throttle again. My suggestion for some one landing a MK111c for the first few times would be to make all approaches under power with plenty of flap. Doing it this way will get you out of trouble if you miss judge something at the last moment . I always take off with 50% flap,lift the tail about 30 mph and rotate at 50 to 55 hold the nose down momunteraly then point the nose at the sky and maintain a steady 55 /60 to 1000 ft. Flying solo I reduce the speeds by about 5mph.I also prefer to use grass to land on .My first couple of attemps of taking off on a sealed runway had much the same results as you have explained .To work out the speeds for rotating I simply judge how far aft I have to pull the stick with a givin AUW, If you try and rotate too slow the stick will be right back and you will find you need to push it forward to get your best climb out speed. After some practice you will be able to judge where the stick needs to be with a given load. Practice.practice.practice. A very forgiving and fun aircraft, just always remember if you pull the stick back without either speed or power you are going to stop flying .It is not forgiving at real slow speeds close to the ground.There are others who may disagree with what have said here and thats OK. We all tend to work out what suits us and develope our own operating practices from there.

Subject: Re: Firestar Versus Firefly
Date: Mar 17, 2008
Group, I have had a question about the safety of the Firefly in windy conditions. Anyone have a fair amount in a Firefly AND a Firestar? Just pondering the differences. The Firestar weighs more but it also has more wing area. Anyone know which one has the highest wing loading. Lastly, If a Firestar and a Firefly were being flown cross country would a Firefly be more vulnerable if the wind got a little brisk, or would they both behave about the same. Ed FF#62 Ed, This is worth less than you payed for it myself only having flown an old original Twinstar and my own Mk-3, but I would guess not much differance between a Fly and a FS. In fact with the smaller wing I would not be surprised if the quicker handling Firefly would be easier in rough air as well as on the ground in high wind. Less wing for the wind to blow around.

Subject: fuel system plumbing, aux tank
I'm adding an auxiliary tank to my UltraStar... I have a pretty good idea of how I'll plumb it, but I'd like to collect some other opinions. My US has the stock setup with two 1.75 gallon tanks under my legs. I'm at a bit of a loss why the valves (the ones that plug into the tanks through a rubber bushing) have two outlets. The manual says to cap one side of one tank's valve, connect the two tanks together, and run the remaining outlet to the engine. When I got my plane, there was no cap, the tanks were connected as per the manual, and both outlets were connected together via a "Y" fitting, thence to the engine. Other than replacing all the tubing, I left it the way it was (but see below). I've considered moving the bulb primer to one leg of the "Y". This would require closing the other tank valve when priming, but with both valves open would give the fuel a path around the primer bulb in case of blockage (such a blockage in a brand new primer bulb almost ended my first flight before I made it around the pattern once). Thoughts? But on to the real reason for this post. The new 1.5 gallon (for a total of 5 gallons) tank will be mounted, quick release, to the rear of the seat (I'm actually mounting it to the seat back itself as I don't want to do any welding on the cage). I'm also using a quick disconnect connector in the fuel line so I can remove the tank if I need to carry it somewhere to be filled, for example if I land out somewhere and have to get fuel. The separate removable tank also makes oil mixing easy. Since this tank will be above the other tanks, I'll open the valve to drain it down when the others are half empty. The issue is plumbing. The obvious thought is to simply connect it via a tee fitting into the fuel lines. However, I'm concerned that once the aux tank is empty the fuel pump will start sucking air from the aux tank instead of fuel from the lower tanks, which would be a bad thing. :) The alternative, which seems the best approach, is to connect the aux tank into a new fitting on top of one of the main tanks... but I'm open to other thoughts and suggestions. I'm also naturally concerned with getting any debris from the drilling out of the tank (I'd rather not have to drain and remove it, etc.), and drilling large holes in thin plastic is a PITA anyway, so my thought is to drill the hole with a sharpened piece of tubing rather than a conventional drill. -Dana -- Diplomacy: Saying "nice doggy" until you find a rock. ________________________________________________________________________________

Ed: Routinely operate the Fly in pretty fair (15-25 mph) breezes...no problem except for folding and unfolding the wings in airish conditions while working alone.. IMHO, that is the single most problematic part of operating it in winds. On landings in higher crosswinds the first thing it used to run out of was rudder, but the VG's on the vertical tail have improved that situation. Mine has the big 15 inch chord ailerons and they seem to give plenty of authority to handle crosswinds. I never droop 'em while landing in crosswinds, and I would sure wheel land it with some power if the crosswinds were stout. Never flew a Firestar, but usually a shortwing gives a better ride in rough air...I know from experience that's the case in Pipers. Not sure what cross country vulnearability you are referring to... generally, if you can get it off and back onto the ground in reusable condition, the cross country part (aside from the fascinating 25 mph groundspeeds one occasionally sees) is just a matter of how rough you like it and what you had for breakfast.

Subject: Landing Stalls
Date: Mar 17, 2008
The best part of this list is the way we share ideas. Also could we all just call it a "stall" that is really what it is. My understanding is that new pilots have a problem with how quickly these planes slow from flying speed to a stall. There is also the comfort level of seeing a rather panoramic view of the ground coming up at them real fast. This is a fault of a Kolb (so to speak) because it has such great visibility. The result is that people have this inborn and in the case of GA pilots "training " that has them fairing too high. Some new flyer just E-mailed us about this very issue very accurately describing it. I think that new pilots should set up their approach that has the lowest decent rate/angle and gives the new pilot them most time to pull up and adjust to a good landing flair. This can best be accomplished with no flaps and some power. Flaps do two things, they increase the decent rate/angle and they increase the rate of speed that these planes slow down. You can set up gentle approach with flaps but you have to greatly increase the power accomplish it. The main problem is loosing power on approach would be a bad thing. The more power you have to depend on the worse it could be. Flaps also produce more drag than they reduce stall speed. Using flaps will slow the plane quicker than the reduced stall speed will help. Also someone suggested using slips and throttle to get to their desired landing point. Slips are less effective than flaps so why not use flaps. adjusting power, primarily increasing power greatly increases the odds of a power failure. I believe the rule is that if you change the throttle on approach it should only be to reduced power. Flaps can be moved in and out as necessary on approach to get to your desired landing point. You just have to adjust your pitch according to your flap usage. As always worth what you paid for it.

On your first landings keep the power maybe on 25% till you are within less than a foot of the ground. Then and only then cut the power. Also don't use flaps at all. As you get more experience SLOWLY reduce the power you set for approach or set one notch of flap. Don't do both at the same time. In fact you may be better off adding a bit more power the first time you use one notch of flaps. Some of us still carry some power with lots of experience. I like to carry some power because landing with one notch of flaps with some power will feel just like no power (engine out) with no flaps. I know this first hand. Some of us never use full flaps other than for brief periods on approach to hit the landing point you want. There is one of our members that uses full flaps and power off on all his landings but I would wait for that after your first thousand landings and even then approach it with added power. There will be those that will tell you I'm being too conservative but most GA pilots will have problems if they move too fast to flaps and no power.

I have run into electrical problems involving the fitting of a larger battery, in a different place of course. This should be done in the next couple of days and then I shall have to recalculate the C of G and then with luck, Wx permitting, which is unlikely according to the forecast I may be able to fly. Providing the strip is not still under water. We have floods for the 3rd time this year. Gales and Very low temps forecast for Easter. Looking back. I wish that I had bought a plane from the second hand market and then I would at least have continued to fly. during the protracted rebuild and the follow on problems.

Great minds think alike :) I had considered doing the Adel clamp thing, but the shape of the tank and the routing of the control cables, etc., seems to make the seat back mounting more logical, plus I have some nice aluminum channels that slip perfectly over the tank flanges so I can slide it in instead of bolting it... the tank I'm using is here: http://fluids.flambeau.com/multipurpose_tanks/6.0_quart.html I also considered adding a new 5 gallon tank above the engine and using the original tank space for storage, but that was more work than I care to do at the moment.

Dana: Not to disagree, too much, but Kolbs will also float, especially when you do not want them to. If you are in a tight situation and your Kolb has no brakes, the Kolbs will float forever. Amazing what ground effect and Kolbs will do. Get her right down there a foot or so off the sod and she will float. My MKIII with 40 degrees of flaps and it will float. One of the secrets of getting a Kolb to float is to shoot your approach a little hotter than normal. I judge others landing mistakes by my own many times. This flight to TNK and back I had a lot of time to think and to fly and land. We were taught to hover a rotary wing by looking out ahead of the aircraft, not down at the ground. We were taught to land them the same way, looking out ahead of the aircraft. Landing a Kolb is no different in this respect. Look out at the end of the runway when landing and the Kolb will gentlely kiss moma earth. Look down at the ground where she is going to drop in, and that is probably what she will do. Try it both ways and see what happens. Hard to judge distance looking down. john h mkIII Compared to a GA bird, the Quick's kinda like a Kolb, only more so (you just dive at the runway, 'cuz no matter what you do it's not going to float!). -Dana ________________________________________________________________________________

Howard- I got them from Travis at TNK. They fit, but it is a tight fit. Dan Glib in Arizona owns a FS II and he gave me some advice which worked pretty well. I'll send you off-line a pic he sent of his installation that helped me. At his suggestion, I put velcro strips on the tanks where the cage tubing comes in contact to prevent wear, as the 6 gal tanks are not as thick walled as the 5 gal tanks are. It worked out nice. The tanks actually hold 6.5 gal with a little air-room left, so it really gives you 13 gal.

I put the fences on after flying it with no center section. I could tell a lot of lift was being lost. The fences prevent spillage off the wing roots. I figure I have the best arrangement due to better airflow and less drag. Any airfoil that has an engine popping up through it can't provide much lift.

I have always believe the FireFly was about the best little airplane at handling crosswinds of anything in the 500 lb class....or maybe even 600 ponders...

Look close at the very begining at the windsock...standing straight as a board...And the FireFly was completely predictable and no sweat to control at all. there were 2 Firestar owners there that day...hanger mates , and they both told me after I was done they would dare fly in this wind... And for what its worth, My Kitfox speedster is 700 lbs empty and is way too much of a handful on the ground to fly comfortably in the same conditions. It will do it...but its a thrill....and more risky. FireStar land slower, and lifts more though, so for cross country...it might be a better pick. with a 503 it oughtta be almost as fast as a FFly. Hard to say. I alway thought if I build another FireFly, I would not cut the wing spar tube and leave it as shipped, which would add almost 2 feet of wing.( 20 inchs if I remember right ..not quite a FireStar...but all you would need is to add a rib on each side and you make better use of the materials sent, and The Fly would land a tad slower and haul a bit more without getting mushy...sort of a cross between them..........

Hard to tell from the pictures, it looks like they're only about 2" high, is that right? Surprising that such a low fence would have that much effect. Another plus is that you could leave a cutout in the root so you could see into the wing for inspection, and the lexan would cover it. Do they get in the way of folding the wings? -Dana -- I started out with nothing. I still have most of it left. ________________________________________________________________________________

Date: Mar 18, 2008
Dana, since they are clear lexan they are difficult to photograph :) They are 1/8" and the same scratch resistant sheet that I used for the windshield and the doors. Remarkably I only had to buy one sheet for the whole plane. They are glued with GOOP to the root ends and are very secure. You can use them to lift the wings. I remove the wings every year and they require a bit more care in storage. The nose end of the wing has to be elevated so the fence hangs free. I'm sure a long period of weight would cause a permanent set. They extend roughly 2"" all around but not quite to the very rear. So far this season has been a non-starter, nursing an old dog back to health, getting the flu myself. Maybe next week I'll get started on the next modification. BB DSCN1164.JPG

I believe Don G made his first landing in a Kolb sitting in my left seat. Could be wrong. Memory is wore out. I like to fly final with no power. My thoughts are, if I fly final with power and I get used to it, when it goes away, I may come up short. 25 kt cross wind is well beyond the capabilities of my mkIII. Probably 15 mph would be more in the ball park for successful landings, using a shot of power to help power the rudder and get her straight on touch down. 25 kts and I'll land cross ways on the runway. I have been in situations where it was impossible to align the aircraft with the runway at altitude flying 85 mph IAS. No way to land at that airport, so find another that has a cross wind strip. Cross wind landings on grass are a piece of cake compared to windy, gusty conditions on pavement. With my wide main gear I can slide more sideways than roll forward. john h mkIII ________________________________________________________________________________

Subject: Re: Landing Stalls
Date: Mar 18, 2008
David/All I need to proof read better. Actually I expected someone to react more to the suggestion of using flaps. When I told my check ride instructor about it he said NO!!!! you never ever retract flaps on final. OK some common sense. First, don't do this while nibbling at stall. Also, I like to stabilize my approach on short final, so short final.... not real short. There is a somewhat common myth that you will stall if you retract your flaps on final. Think about it, when you raise your flaps you are effectively reducing the angle of attack of the wing. It is angle of attack that causes a stall. In a Kolb when you raise the flaps on final you will get a bit of pitch up trim change and the plane will increase speed rather quickly. As the speed increases you will want to raise the nose a bit to keep your speed under control but don't over control. Practice this a bit at altitude. Set up a high altitude approach. Lower your flaps and lower the nose of your plane. Raise the flaps and raise the nose. Try to keep your approach speed constant. Notice the change in the potential landing point. It works well and no, the plane never comes close to stalling. A few years ago I had a engine out on the way back form Oshkosh. I had practiced the variable flap approach and had discussed a no flap engine out landing with the Kolb guys in the Ultralight campground so I had a plan fixed in my mind when it happened. I picked a landing spot and used the flaps to put me exactly where I wanted to land. I never locked the flaps in any notch but used it like someone would use a throttle to adjust my glide slope. When I had my landing spot made I fully retracted my flaps and made one of my best landings ever. Yes I could have landed slower with flaps but I'm not that great a pilot and landing with no power and no flaps is just like landing with one notch of flaps and some power. I normally land with some power and one notch of flaps. In an emergency why make it more difficult? When you have and engine out you don't have a throttle to adjust your glide slope. So why not practice what you might need someday. Also changing throttle settings especially increasing the throttle on final isn't a real good idea IF there is a better way. Yes it is the same sport. Again worth what you paid for it.

Also could we all just call it a "stall" that is really what it is. My understanding is that new pilots have a problem with how quickly these planes slow from flying speed to a stall. There is also the comfort level of seeing a rather panoramic view of the ground coming up at them real fast. This is a fault of a Kolb (so to speak) because it has such great visibility. The result is that people have this inborn and in the case of GA pilots "training " that has them fairing too high. Some new flyer just E-mailed us about this very issue very accurately describing it. I think that new pilots should set up their approach that has the lowest decent rate/angle and gives the new pilot them most time to pull up and adjust to a good landing flair. This can best be accomplished with no flaps and some power. Flaps do two things, they increase the decent rate/angle and they increase the rate of speed that these planes slow down. You can set up gentle approach with flaps but you have to greatly increase the power accomplish it. The main problem is loosing power on approach would be a bad thing. The more power you have to depend on the worse it could be. Flaps also produce more drag than they reduce stall speed. Using flaps will slow the plane quicker than the reduced stall speed will help. Also someone suggested using slips and throttle to get to their desired landing point. Slips are less effective than flaps so why not use flaps. adjusting power, primarily increasing power greatly increases the odds of a power failure. I believe the rule is that if you change the throttle on approach it should only be to reduced power. Flaps can be moved in and out as necessary on approach to get to your desired landing point. You just have to adjust your pitch according to your flap usage. As always worth what you paid for it.

New to the Forum Date: Sun, 16 Mar 2008 14:10:28 -0400 Joe As Ed has suggested your biggest problem is landing. Your experience will serve you poorly. On your first landings keep the power maybe on 25% till you are within less than a foot of the ground. Then and only then cut the power. Also don't use flaps at all. As you get more experience SLOWLY reduce the power you set for approach or set one notch of flap. Don't do both at the same time. In fact you may be better off adding a bit more power the first time you use one notch of flaps. Some of us still carry some power with lots of experience. I like to carry some power because landing with one notch of flaps with some power will feel just like no power (engine out) with no flaps. I know this first hand. Some of us never use full flaps other than for brief periods on approach to hit the landing point you want. There is one of our members that uses full flaps and power off on all his landings but I would wait for that after your first thousand landings and even then approach it with added power. There will be those that will tell you I'm being too conservative but most GA pilots will have problems if they move too fast to flaps and no power.

Now I do it all the time in the titan in case I'm coming up short with too much flaps out and I'm practicing energy management (i.e. don't want to add power). It works perfectly and makes sense as well - if you have too much drag, but you have enough potential energy (altitude) to make the landing with a lower drag config... why not reconfigure to the lower drag config? Another interesting exercise is to do a low fly by in the flare attitude and at a little above landing speeds with the flaps out. Then slowly start nursing the flaps up but continue to maintain altitude (a foot or two). A real eye opener which really tests your abilities with the power and elevator.....

> I have had a few good comments and tips. Does anyone else want to chime in? Come on guys i know you all have some sort of technique. :) Grant: I don't think there is any "special" techinique to fly a Kolb. I think the name of the game is to fly the aircraft and not let the aircraft fly you. Using 40 degrees of flaps, idle power, to shoot an approach is not technically demanding. Got to keep the aircraft above stall speed with enough speed at the bottom to do a little flare and touch down. No need to adjust flaps, throttle, or anything else except the control stick. If you need to go faster, push the stick forward, if you want to slow up, pull it back. The approach will be steep, much steeper than other airplanes, more like a rotary wing approach and landing. If you were shooting a landing into a postage stamp field, use a little throttle to help you hit your mark. I can do this and keep my left hand on the throttle and my right hand on the stick. I am not busy moving my hand from one control to another. Keep it simple. It is a very simple aircraft. Why make it complex? Kolbs fly like any other three axis aircraft. The pilot must make the proper decision to control the aircraft and not vice versa. If you want to do full stall landings, do them a few inches above the ground, not 10 feet. If you want to do a wheel landing, fly the darn thing onto the ground. I flew a Legend Cub the other day with a 100 hp tractor engine. Darn thing landed just like my Kolb MKIII. Granted, it did float a little more, but basically I controlled it basically the same way. I very seldom fly any other aircraft except Kolbs. john h mkIII ________________________________________________________________________________

Bill, your choice of a gap seal will be influenced by whether or not you'll be folding the wings often. I fold all the time, and the original gap seal was missing when I bought the plane, so I made a simple gap seal out of heavy gauge clear plastic (the kind they use for windows in convertible tops), and attach it to the wings with 2" wide velcro. Some pix at: http://smg.photobucket.com/albums/v486/flyparafan/Kolb/ It goes on easy, seems to be holding up fine, and doesn't block my visibility. -Dana -- "You sure it's broken?

Subject: Firestar Project
Just an update on the Firestar project. Both wings have had the holes patched. One wing has a slight dent in a rib, behind the thickest part on the top. I don't think it will bother anything, and I'm certain no tubes were broken, so I'll leave it alone for now. Both wings are now on the plane, in the folded position. I had the muffler and manifold sandblasred for $20. I welded a "star" crack in the muffler intake elbow with a gasless MIG. Very delicate welding- I think the material is brittle, and thinned out. A lot of exterior pitting- salt air, maybe, as it came from Long Island and was flown frequently over salt water. The manifold was drilled for two more holes, and installed with a total of 6 bolts and new gaskets. The muffler is painted but not installed- too dark last night and raining today. The muffler was rubbing on the fan shroud- I'll have to space it out. The new tires I installed had cracks between the ribs, so Aircraft Spruce immediately exchanged them. Excellent service from them. I have the option of having a ground adjustable AOL by drilling a couple more holes in the front mounting adapter channels. It could give me a total of 3 available AOL's, if I set the aileron control rods correctly. Has anyone ever tried this? Keep in mind that the wing is 2 1/2" back from standard mounting. The gap seal will have to wait until I figure out whether I will build or borrow a trailer. I still have to set and weld new aileron control rods, switch out the bent landing gear legs, fix the static port on the ASI, and mostly wait out the miserable weather. I am also eyeing the original wings for repair and modification, as my living room is empty again. The wife is still tolerating me, but I might be pushing it.

I'm Open for an education here. but I was told that the shortest take off roll, at least from a hard surface, was to get the tail up after adding power, and this would allow you to accelerate faster because of reduced drag on the wing, then pull the stick back when up to take off speed. I have done testing, taking off clean, 20 & 40 Deg flaps. Both clean and 40 deg flaps had , as close as I could tell, the same takeoff roll, and 20 deg flaps was 50 to 100 ft shorter. The explanation was that even though 40 deg of flaps should allow you to fly slower because of greater lift, the extra drag caused a much slower acceleration. Now I can hear you thinking between the lines. if 40 was slower why not 20 Deg of flaps being shorter as well.. The explanation would be that if you chart the lift to drag ratio on a chart,,,, 20 deg of flaps produces quite a bit of added lift with only a small drag penalty,,, while 40 deg of flaps, while producing a little more lift than 20 deg, is affected by much higher drag ratio. In getting a tail dragger endorsement in a supper cub,, the shortest takeoff was starting with 10 deg flaps, getting the tail up to reduce drag on the wings then, at the same time, pulling the stick back while adding additional flaps. Again this if from a hard surface runway,,,, soft field takeoff would be quite different. Boyd >>>>>>>>>>>>>>>>>>>>>>>>>.

Couple of things You said "when you raise your flaps you are effectively reducing the angle of attack of the wing. It is angle of attack that causes a stall. In a Kolb when you raise the flaps on final you will get a bit of pitch up trim chan ge and the plane will increase speed rather quickly" On my plane if I l raise my flaps I'm lowering the angle of attack of the w ing.On my plane if I raise my flaps the plane will speed up.On my plane if I raise my flaps lift is decreased and the plane it is likely to go down. ( try it over the runway at 10 feet or so)On my plane if I raise my flaps and I'm under Vs then the plane will stall immeadatly. I'm encouraged that your instructor agrees that it is not good pratice to t ool with the flaps on final.

First, don't do this while nibbling at stall. Also, I like to stabilize my approach on short final, so short final.... not real short.

It is angle of attack that causes a stall. In a Kolb when you raise the flaps on final you will get a bit of pitch up trim change and the plane will increase speed rather quickly. As the speed increases you will want to raise the nose a bit to keep your spee d under control but don't over control. Practice this a bit at altitude. Set up a high altitude approach. Lower your flaps and lower the nose of you r plane. Raise the flaps and raise the nose. Try to keep your approach spee d constant. Notice the change in the potential landing point. It works well and no, the plane never comes close to stalling. A few years ago I had a engine out on the way back form Oshkosh. I had prac ticed the variable flap approach and had discussed a no flap engine out lan ding with the Kolb guys in the Ultralight campground so I had a plan fixed in my mind when it happened. I picked a landing spot and used the flaps to put me exactly where I wanted to land. I never locked the flaps in any notc h but used it like someone would use a throttle to adjust my glide slope. W hen I had my landing spot made I fully retracted my flaps and made one of m y best landings ever. Yes I could have landed slower with flaps but I'm not that great a pilot and landing with no power and no flaps is just like lan ding with one notch of flaps and some power. I normally land with some powe r and one notch of flaps. In an emergency why make it more difficult? When you have and engine out you don't have a throttle to adjust your glide slope. So why not practice what you might need someday. Also changing thro ttle settings especially increasing the throttle on final isn't a real good idea IF there is a better way. Yes it is the same sport. Again worth what you paid for it.

Also could we all jus t call it a "stall" that is really what it is. My understanding is that new pilots have a problem with how quickly these p lanes slow from flying speed to a stall. There is also the comfort level of seeing a rather panoramic view of the ground coming up at them real fast. This is a fault of a Kolb (so to speak) because it has such great visibilit y. The result is that people have this inborn and in the case of GA pilots "training " that has them fairing too high. Some new flyer just E-mailed us about this very issue very accurately describing it. I think that new pilots should set up their approach that has the lowest de cent rate/angle and gives the new pilot them most time to pull up and adjus t to a good landing flair. This can best be accomplished with no flaps and some power. Flaps do two things, they increase the decent rate/angle and th ey increase the rate of speed that these planes slow down. You can set up g entle approach with flaps but you have to greatly increase the power accomp lish it. The main problem is loosing power on approach would be a bad thing . The more power you have to depend on the worse it could be. Flaps also pr oduce more drag than they reduce stall speed. Using flaps will slow the pla ne quicker than the reduced stall speed will help. Also someone suggested using slips and throttle to get to their desired lan ding point. Slips are less effective than flaps so why not use flaps. adjus ting power, primarily increasing power greatly increases the odds of a powe r failure. I believe the rule is that if you change the throttle on approac h it should only be to reduced power. Flaps can be moved in and out as nece ssary on approach to get to your desired landing point. You just have to ad just your pitch according to your flap usage. As always worth what you paid for it.

On your first landings keep the power maybe on 25% till yo u are within less than a foot of the ground. Then and only then cut the pow er. Also don't use flaps at all. As you get more experience SLOWLY reduce t he power you set for approach or set one notch of flap. Don't do both at th e same time. In fact you may be better off adding a bit more power the firs t time you use one notch of flaps. Some of us still carry some power with l ots of experience. I like to carry some power because landing with one notc h of flaps with some power will feel just like no power (engine out) with n o flaps. I know this first hand. Some of us never use full flaps other than for brief periods on approach to hit the landing point you want. There is one of our members that uses full flaps and power off on all his landings b ut I would wait for that after your first thousand landings and even then a pproach it with added power. There will be those that will tell you I'm bei ng too conservative but most GA pilots will have problems if they move too fast to flaps and no power.

There is a somewhat common myth that you will stall if you retract your fla ps on final. Think about it, when you raise your flaps you are effectively reducing the angle of attack of the wing. It is angle of attack that causes a stall. In a Kolb when you raise the flaps on final you will get a bit of pitch up trim change and the plane will increase speed rather quickly. As the speed increases you will want to raise the nose a bit to keep your spee d under control but don't over control. Practice this a bit at altitude. Set up a high altitude approach. Lower your flaps and lower the nose of you r plane. Raise the flaps and raise the nose. Try to keep your approach spee d constant. Notice the change in the potential landing point. It works well and no, the plane never comes close to stalling. A few years ago I had a engine out on the way back form Oshkosh. I had prac ticed the variable flap approach and had discussed a no flap engine out lan ding with the Kolb guys in the Ultralight campground so I had a plan fixed in my mind when it happened. I picked a landing spot and used the flaps to put me exactly where I wanted to land. I never locked the flaps in any notc h but used it like someone would use a throttle to adjust my glide slope. W hen I had my landing spot made I fully retracted my flaps and made one of m y best landings ever. Yes I could have landed slower with flaps but I'm not that great a pilot and landing with no power and no flaps is just like lan ding with one notch of flaps and some power. I normally land with some powe r and one notch of flaps. In an emergency why make it more difficult? When you have and engine out you don't have a throttle to adjust your glide slope. So why not practice what you might need someday. Also changing thro ttle settings especially increasing the throttle on final isn't a real good idea IF there is a better way. Yes it is the same sport. Again worth what you paid for it.

Also could we all jus t call it a "stall" that is really what it is. My understanding is that new pilots have a problem with how quickly these p lanes slow from flying speed to a stall. There is also the comfort level of seeing a rather panoramic view of the ground coming up at them real fast. This is a fault of a Kolb (so to speak) because it has such great visibilit y. The result is that people have this inborn and in the case of GA pilots "training " that has them fairing too high. Some new flyer just E-mailed us about this very issue very accurately describing it. I think that new pilots should set up their approach that has the lowest de cent rate/angle and gives the new pilot them most time to pull up and adjus t to a good landing flair. This can best be accomplished with no flaps and some power. Flaps do two things, they increase the decent rate/angle and th ey increase the rate of speed that these planes slow down. You can set up g entle approach with flaps but you have to greatly increase the power accomp lish it. The main problem is loosing power on approach would be a bad thing . The more power you have to depend on the worse it could be. Flaps also pr oduce more drag than they reduce stall speed. Using flaps will slow the pla ne quicker than the reduced stall speed will help. Also someone suggested using slips and throttle to get to their desired lan ding point. Slips are less effective than flaps so why not use flaps. adjus ting power, primarily increasing power greatly increases the odds of a powe r failure. I believe the rule is that if you change the throttle on approac h it should only be to reduced power. Flaps can be moved in and out as nece ssary on approach to get to your desired landing point. You just have to ad just your pitch according to your flap usage. As always worth what you paid for it.

New to the ForumDate: Sun, 16 Mar 2008 14:10:28 -0400 Joe As Ed has suggested your biggest problem is landing. Your experience will s erve you poorly. On your first landings keep the power maybe on 25% till yo u are within less than a foot of the ground. Then and only then cut the pow er. Also don't use flaps at all. As you get more experience SLOWLY reduce t he power you set for approach or set one notch of flap. Don't do both at th e same time. In fact you may be better off adding a bit more power the firs t time you use one notch of flaps. Some of us still carry some power with l ots of experience. I like to carry some power because landing with one notc h of flaps with some power will feel just like no power (engine out) with n o flaps. I know this first hand. Some of us never use full flaps other than for brief periods on approach to hit the landing point you want. There is one of our members that uses full flaps and power off on all his landings b ut I would wait for that after your first thousand landings and even then a pproach it with added power. There will be those that will tell you I'm bei ng too conservative but most GA pilots will have problems if they move too fast to flaps and no power.

The 6 gal tanks fit fine if you turn the front one sideways so the handle does not interfere with the frame cross member (makes it easier to fill from the side anyway). Definitely a great deal from TNK. The other thing you can see in the photo is that the front tank sticks forward enough to interfere with the rear sling seat.

Torque will only roll the plane, not yaw it. P-factor will tend to yaw the plane, but only at higher angles of attack (i.e. it'll want to yaw the plane while the tail's down, but not afterwards). If the plane tries to yaw just as you lift the tail, that's gyroscopic precession, all taildraggers do it to a greater or lesser extent; you just have to be ready for it. A misalignment between your tailwheel and rudder could be causing it, too. > My plane does not have differential brakes on it either so its all > rudder for the steering.

To be honest, I really wasn't very frustrated, either. If Kolbs have a s lightly peculiar landing tendency, and someone advises you about it, would you not, then, avoid that tendency?? Is it that bad that it cannot be avoi ded? I have no quarrel with anyone about their views and opinions about flying their planes, and whatever landing technique they find pleasing. My posit ion was I was just trying to point out that I don't believe Kolbs have an " eary" landing style. They don't, do they? I wouldn't know, because I haven't flown one, yet.

My trustee Kolb MKIII is without a doubt the most enjoyable and scenic airplane that I have ever flown which includes my next favorites, the J-3, the Hummer, Kasperwing, and most taildraggers of the 1940's and all hang gliders and sailplanes. I like it especially in the summer time with my 1/2 doors. The air circulation is perfect and the visibility is even better; and, I get more air to the prop. All good things. If there is a negative, it is the prop noise that finds it's way forward. (working on that) My MkIII reacts very similar to a J-3 in both performance ahd handling. Yes, I have performed the famous Kolb drop and am almost expert in rebending gears legs. The reason for my dumbness is because I have tried landing like a Cub or Citabria wherein the tail wheel will hit slightly sooner that the mains at full stall. That would be fine were my heights not so high. I am fairly certain that gap seals and VG's on the elevator would help, but then the tail wheel would c o! ntact too much before the mains come down. Enough for the learning curve. Now, with VG's on the wing (52 ea), it floats down gently. At 60mph approach, 50 mph round out to about 2 feet and very slight release of elevator it just sits on the runway rolling along slowly after the tailwheel hits only slightly before the mains. It is a delight. The advise here on the net has been good and having a little power on landing is both safe and reassuring. It is a pilots choice.

Mike .... trust me it is small but a real problem to those who have never experienced Kolb drop. I have bent 7 axles and 5 I would have gto say wee due to this phenomenon. Personally, I think it is due to the angle of incidence between the horizontal stabilizer and the wing, what this means is that some of the wing and tail is approaching stall even when flying cruise. ie, it is a draggy configuration that provides very good stability. You might say it makes washout unnecessary to achieve the stability of slow flight, you know how a washout wing first stalls in the middle then the stall progresses out to the wingtips as the plane slows down? But you still have some lift due to the unstalled part of the wing, but you will sink..... just like the Kolb does. Well, it has Verrry little dihedral for slow stability, soooooo it uses the angle of incidence between wing and tail to achieve that necessary ingredient. This is just part of the story, but touches on the main parts to explain Kolb drop.

I would say it it like this, when you are learning to fly a Kolb...land with power...and the more you learn the less power you will need...but then...that depends on the wind too...I didnt land at Idle every time...depends on how good I set up on final..If you get low...and set up slow..you will need power...but you can dive it in from unbelievable angles and pull level above the turf and set it right in also...because it does not float. About the worst thing I can think of about a FireFly is...it handles and preforms so well, it will seriously tempt you to do thing you should NOT do in it. I cannot speak for other models than the FireFly however... and Your memory ain't that bad John....my first ride in a Kolb was in yours pard... Built the plane and had never had even a ride, till you came by showed me the ropes and as I look back, the conversations we had were of more value then the actual ride. (Even the ones about Kolb flight charactistics) What I will speak of as to the FireFly...it does not take long for that little bird to just become a part of you...and you can do things with it by just "feel". The FireFly has no bad habits...its super predictable.. After a fella figgers out just how fast it gonna drop in and at what speed....just make sure your wheels are really close to the turf when you arrive at that speed...weather you have power or not. I have flown a ton of different part 103 birds...going all the way back to the begining..late 70's and my first...a weedhopper.. But absolutely none compare with a FireFly. It may be 103 compliant by weight...but it really stand head and shoulders above the rest. Like the difference between a 175cc moped and a 175cc motocrosser...it just handles real well and performs... Learn it, and you can do things the others cant even dream about. Now...I didnt learn the complete envelope without making mistakes...but I never bent more than one gear leg at a time! I'll tell you something else about learning to fly the FireFly. Before I had mine done...I stood down at Sun-N-Fun the year when the "other Flagfly" won grandchampion ultralite...(the one that inspired my paintjob) and I watched a fella fly that thing all day long. I said to myself...jeez...that guy must live in that airplane...he is the smoothest stick I have ever seen. I had seen other Kolbs fly locally, and alot of em ploppin em in...staggering them up in the air..but this guy...I just knew he had must have lived in that pretty bird. I watched him real careful and learned an awful lot...I watched the elevators and listened to the engine..watched him shoot dozens and dozens or takeoffs and landings.

It does not matter what you call it, the Kolb drop, stall, or whatever you want to label put on it, it does exist. The Kolb has a much greater tendency to lose its energy on landing, and result in a sudden drop on landing, resulting in a lot of bent gear. I have no use for people in denial, or that try to explain away facts, it is what it is. Cessna and most other GA aircraft are more forgiving on landing, that just the fact. There are a couple things you can do about Kolb Drop, the best is to install VG's on your Kolb, VG's will practically eliminate this in a Kolb, not totally eliminate, but it will make a dramatic difference. Second is to recognize this flight characteristic and learn to deal with it. I have no problem landing my Kolb, but I am not perfect, so for the times I do not execute a perfect landing, and it happens to all pilots, the VG's make it forgiving enough that I don't bend anything.

I really hope we can move on to another subject. Every aircraft has its own particular stall behavior. A Cessan is different from a Piper, which is different from a P-51 which is different from a Quicksilver or... a Kolb. I haven't heard anybody denying that Kolbs fly like... well, Kolbs, but calling it the "Kolb Drop" or anything else, like it's something unusual, is absurd, as is expecting a Kolb to fly just like a Cessna (or a P-51). Taylorcrafts (which I mention because I used to own one), for example, have a tendency to float forever on landing if you don't start your flare rather early, compared to, say, a Cub (or a Kolb!), but nobody calls it the "T-Craft Travel" or anything like that. If you want to mellow your Kolb's stall behavior by installing VG's (and accepting any compromises that might entail), have at it. But it doesn't mean a Kolb with VG's is "better" (or "worse"), or one without VG's is "bad"; it simply reflects the preferences of the owner. -Dana -- When you get it right mighty beasts float up into the sky When you get it wrong people die -Roger Bacon (c1384) ________________________________________________________________________________

There is no downside except the 100 bucks they cost and a couple hours of work. One of the main reasons I bought a Kolb was because of its short field, and slow speed capability. Being able reduce the stall speed by 10 MPH, and have a plane with a much better feel at slow speed made VG's worth the 100 bucks they cost many times over. Getting rid of the Kolb Drop on landing was just an added bonus I did not expect. R Hankins, Aircraft manufacturers go to a lot of research and effort to make planes more forgiving and fly better. Most people and manufacturers are smart enough to recognize that good design is important. To blame bad flight characteristics of an airplane on pilots poor skills rather than fixing an obvious problem is just plain stupid. Gone are the days of airplanes that were unstable, hard to fly, and would spin at the first chance, we are fortunate that aircraft design improved rather than just blaming the pilot each time a plane went into a spin an crashed. The Kolb drop is an undesirable characteristic of the planes we fly, it is what it is. Fortunately, it is easy enough to fix for those smart enough recognize it and open minded enough to try VG's.

Droop tips work very well for STOL type aircraft, like KOLBS. If the benefit of the Droop tips is great enough, I will modify my Kolb and put them on. I'm glad to see TNK improving their planes, that is exactly what is needed to any aircraft design and company to survive long term. Homer designed the Kolb more than 20 years ago, a great design to have survived this long, but definitely should be improved to remain competitive. Winglets are mostly for saving fuel at cruise speeds, not really an issue on Kolbs. Since when have you seen winglets on STOL type airplanes ? Seems someone did not think things through very well they said they don't like droop tips because everyone else is going to winglets.

Subject: stalls
Dana- I recieved my training on an Alon A2 Ercoupe about 40 years ago, and we could definately stall them. I could not get spin training, because Ercoupes did not have enough rudder. If I remember, the stalls were typical- quiet, light in the seat, a shudder, and a wing would start to drop. Recovery was also standard- power, and push the nose down. I think they weighed about 1300 pounds- 4 times what our Firestar l weighs. The Ercoupe took off at 55, and landed at 88. I don't remember the stall speed.

Generally, for ultralights, I use 1.5 times the stall speed for approach. That would be 45 mph approach for 30 mph stall. In the case of a 45 mph stall speed, that works out to about 67. Slow high drag aircraft are more affected by gusts and gradient than their larger cousins who use 1.3 x stall speed for approach. Also, you end up with more flare energy and can avoid the dreaded "Kolb Kwit"!

My MkIIIC stalls at about 42mph, and I've always used 60mph as my approach speed... which is close to the 1.5 x formula (which would be 63mph). If I feel the need for added authority, I'll approach at 65. When I practice engine-out landing, I'll approach at 60, which is close to best-glide, but when I'm at about 200 feet, I'll point the nose down radically so that I get at least 65mph, so my flare (which bleeds off a lot of speed) won't slow me down below stall by the time I let the planet come up and kiss my wheels. :-) On Sat, Mar 22, 2008 at 4:21 AM, Dave Bigelow wrote: > > Generally, for ultralights, I use 1.5 times the stall speed for approach.

If > you're interested, I can find out. Arty -- I hate to say it, but, this is really bad advice to be handing out. The decreased partial pressure of oxygen encountered at increasing altitude can quickly lead to incapacitation or death. The lethal effects of acute altitude hypoxia cannot be underestimated. Deaths have occurred at altitude between 17,000 and 20,000 feet. Even hypoxic episodes that lead to mental confusion may result ultimately in the loss of the airplane because of the mental disorientation during or after the episode. The atmospheric pressure decrease at 10,000-foot altitude causes 523mm Hg ambient air pressure resulting in 87 percent hemoglobin saturation and 61mm Hg arterial oxygen. At 15,000 feet (429mm Hg) the hemoglobin saturation is 80 percent (we need 87-97 percent for normal functioning), and arterial oxygen is 44mm Hg (the body requires 60-100mm Hg.). Every individual has a different ability to withstand such low partial pressures, and that ability can actually change day-to-day, so it's not predictable. -- Robert ________________________________________________________________________________

Kolb List members, I've been in contact with Clara and Homer Kolb and they have agreed to again host a fly-in at their farm which is outside of Spring City, PA, the birth place of our fantastic flying machines. It will be held on June 14th,, Father's Day weekend as usual. Arrive in the morning and be there by noon for the gathering of pilots and the picnic they most generously provide for us. It's a great time to meet the Kolb family and other pilots that fly in from various locations. The "Barn" contains many of Homer's early designs to take to the air. Also you can see his tractor collection. Many of us gather at Smoketown Airport east of Lancaster City, Lancaster County, PA that morning to make up a flight to go to their farm, come join us. Makes an impressive sight with ten or more planes arriving together, Homer always enjoys that. Will update on plans as we get close to the time. Having been well fed and sharing stories and ideas with the other pilots, most of us leave in the afternoon to fly to an Ultralight Fly-in at "Shreveport North" in York County, Pa where we camp out. That fly-in starts on Friday 13th. before Homer's and lasts through Sunday 15th.. Some have used this fly-in as a stopover from out of state to go the Homer's. Camping is permitted with good food available. It's scheduled again this year, but check in closer to the date. Those that have attended before will tell you what a great time was had and what good people the Kolb's are. Those that haven't made it before should try this year. You get to meet some really interesting individuals that fly or drive in. This is not an event that is scheduled to continue as an annual activity, but at the pleasure and convenience of Clara, Homer and their family. We already skipped one year because they had other plans. The Kolb private airstrip is shown on both the New York and Washington sectionals located northwest of Philadelphia just outside the Phila. B ring along the Schuylkill River. You can also look it up on AirNav.com. Hope you put this on your calender to do and I get to see you there again or for the first time!

My neighbor acquired a Thorp T-18 in a trade a couple of years ago. It had a baggage compartment aux tank plumbed through a shutoff into a 'T' at the bottom of the main tank, which is between the instrument panel & the firewall. It almost quit on him when when the aux tank emptied while flying it home from the trade. In order to prevent it from sucking air, the aux tank valve had to be closed before the tank was completely empty. Bede BD-4 fliers have the same problem due to multiple fuel pickups in each wing tank. (Yes, that's the way the fuel system was designed.) If one pickup 'unports', it will suck air & cause fuel starvation. There's nothing inherently 'wrong' with this; most low wing factory planes require you to switch tanks as the selected tank nears the empty point to avoid sucking air from the empty tank. However, it does add work load & cushion crimp at every tank switching event. But as you fear, it's likely to cause engine stoppage if you forget to shut off the aux as it empties. That might be a much bigger deal in a Kolb with its lower inertia & the likelihood that you'll be flying closer to the ground than would be the case in a bigger factory plane. I'm struggling with the same decision on the RV-7 I'm building now. It'll be much easier to plumb the aux tanks directly to the fuel delivery line, but there's always the risk of engine stoppage when an aux tank runs dry. (Of course, the same thing is true with the 2 stock main tanks, also, & there are almost 5000 RVs flying with that system.)

But it doesn't mean a Kolb with VG's is "better" (or "worse"),>> Hi, that is a strange statement. Is an "increase of 30% on the cruise without compromising the amazing short field performance", better? I would have said so. This is from a flight test of the new `Savannah VG` in the April `Microlight Flying, our major magazine. The Savannah is quite popular here. Around 30 flying. They are all metal with a very thick wing designed for short field performance. Previously they were fitted with a `slot` on the leading edge. This has been done away with in the `VG` variant and vortex generators have been fitted the full length of the wing in its place. In this case we are not talking about `Kolb quit` or any other name for a stall. The Savannah has always had good low speed handling characteristics and there is no mention in the article of landing speeds being affected by the VG`s. There is a mention of a `very` small increase in ground roll and thats it. It is the increase in cruise speed which has caught the observers eye. "The old Savannah was not exactly a sluggard with a cruise of 75-80 mph but this one, with the same old Jabiru up front was slipping along at 100mph at 2700rpm - an astonishing 30% improvement. Gaining 5mph can take masses of tinkering with an established design but here an apparently minor mod has changed it from Land Rover to Range Rover in a single bound` "The Savannah has already proved a popluar aircraft in its standard form but 3 `VG` kits have been sold and it wouldn`t surprise me if if Classic owners didn`t choose to replace the old wing with the new. At around 1000 it seems a snip for all that exttra performance." All this of course begs the question Do I want VG`s or even `do I need VG`s. As far as John H is concerned the answer to both questions is `No` and some others agree but I think there is little point in arguing about the effectiveness of VG`s. That is proved. They do just what it says on the tin. I hereby solemnly swear that I will not ever, ever, ever, write another word to the list about VG`s Cheers Pat ________________________________________________________________________________

I put a 6 gallon Aux tank in my Kolb MK III to give me 16 gallons total fuel. I did not want to complicate the fuel system or run any risk of having my motor quit due to fuel mismanagement by myself ( Made it idiot proof in case I get distracted ). What I did was have the AUX tank feed into an electric Facett pump with an on - off valve. I fly until my main tank get empty enough to take the extra 6 gallons, at which ponit I open the valve and turn on the pump which fills up the stock mains on my MK III in flight. If I forget and leave it on and forget the valve, no harm done, it pumps until empty and then I hear the pump rattling as it starts to suck air when there is no more to pump into the mains. If I pump to early, it just over fills the mains and runs out the vent tube out to bottom of the plane, I lose some gas, but no harm done. Even a failure of any part of the aux fuel system, the fuel hose, pump, valve, etc will not result in engine failure. No matter what I do with this system, there is no way to screw it up to the point of making the engine quit. I added the aux tank and extra 6 gallons of fuel to my stock MK III fuel system with no modification to the cage or original fuel system. When I buy the new 18 gallon tank from TNK I will have 24 gallons of fuel as the AUX will work with the new tank the same way it works with the stock tanks. What I really like about this AUX tank is that I always leave it empty unless I am flying cross country, so for the vast majority of my local flights, only fill the mains with no weight penalty from carrying extra gas. Cost was less than 150 dollars for everything. I can post pictures and schematics for anyone that wants them. Mike I can post pictures and schematic if anyone is interested.

My understanding is that while icing is possible (and does occasionally happen), it's less likely for three reasons: First, the slide carburetors we use are less likely to ice up than the butterfly type used on conventional engines; the oil mixed with the gas makes ice less likely to adhere to the carburetor surfaces, and the nature of the 2-stroke induction means some mixture is blown back part way into the manifold / carburetor before the piston covers the inlet port, heating and/or dislodging any ice. This was some of the information I was given last year when I thought I had an icing problem, but it turned out to be a jetting problem (too rich for the hot humid weather I was flying in). That said, there _are_ outfits making electric carburetor heaters for Bing carburetors (basically a heated plate that sandwiches between the carb and manifold. -Dana -- Stupidity got us into this mess... why can't it get us out? ________________________________________________________________________________

Of course it's less of an issue in a conventional plane, too, because the prop will continue to windmill, and the engine will restart as soon as fuel is restored. I don't recall how my T-Craft was plumbed, but there was no issue leaving the aux wing tank valve open even after it was fully drained into the main tank. But, come to think of it, with gravity feed all the way to the carburetor it wouldn't be an issue anyway. Sometimes it WAS an issue if it failed to start draining when the main tank was empty and the fuel was needed, but that's another story... -Dana -- If we wish to "restore" respect for the law, a good start would be to pass only laws that people will respect. ________________________________________________________________________________

By "I never pulled fuel from the tops" I presume you mean fittings in the bottom as opposed to the dip tube fittings about halfway up that is the US stock setup (I think)? I ordered the push in / rubber grommet fitting with the screen and valve for the aux tank, and I'll run it into the side of one of the main tanks wherever it's convenient. I'll also use a self sealing quick disconnect in the fuel line so I can remove the tank when necessary. -Dana -- If we wish to "restore" respect for the law, a good start would be to pass only laws that people will respect. ________________________________________________________________________________

Ah, the good old days! :) When I learned to fly in 1976 the C-150 was $15 wet and the instructor $10. The only Ercoupe I ever flew (once) was an older (40's?) with no rudder pedals.

> You can go pretty high without oxygen as long as you > don't stay up there very long Alarm Bells Ringing ! ! ! ! In aircraft like Beech Barons, Cessna 402 series etc I used to climb above 10,000 ft to get across the ranges in Papua New Guinea. The VFR gaps through the mountain valleys (at about 8000 ft) would close with cloud by late morning but you'd often find a gap in the cloud above the same gap in the terrain. We'd get up to 14 or so, occasionaly higher, to get through to the other side (but never proceeding without a clear view of good wx on the other side). So we were above 10,000 ft for maybe 20 minutes. Still, even after that short time I would get symptoms of headache telling me its time to get down, and that was when I was young and fit, in my 20's. How long it would take a non turbo charged Kolb to get up to 17,000 ft I shudder to think, unless of course you carried and used oxygen. I was lucky, I would get warning signs that I recognised, others don't get them in time. A dangerous and insidious side effect of lack of oxygen can be a feeling of well being, so much so that it can affect your judgement into thinking your OK whilst it may be exactly the opposite. I know of one guy who went up high to take advantage of a good tailwind which he did get, but he was so euphoric he decided to continue on and not bother about the planned en-route fuel stop. Fortunately luck was on his side and he made it to his destination, but on taxying in the engine stopped due fuel starvation that he was not even aware of. As his body recovered to normal oxygen levels, he realised how lucky he had been. So be careful folks. If you chose to go above 10,000 for any length of time you're courting trouble and you may not even be aware of it ! Safe flying ! David.

Morning Gang: Weather at TNK is lousy! Got up this morning to 34F and now, several hours later, it is a blazing 35F. Well, one good thing, the wind is calm. I flew up to TNK last week, put some ground time on the 912ULS to insure it was going to continue to make good power once I committed to flight. Took me three days to get back home, about 340 sm. Left last Wed to rtn to TNK. Got some flight time Thursday. Worked out a few bugs, even though the wind was kicking ass. Friday got more time and continued to tweek the X, again in uncomfortable winds which are not conducive to initial test flying. Yesterday I got an hour on a flight to London, Williamsburn and return to TNK. It was rough and cold. Could not feel my fingers by the time I landed at TNK. Today is another washout, as far as test flying is concerned, as will be tomorrow. Forecast is snow. I am flying without the droop tips initially. The X has amazing lift based on a 13 foot wing panel. That is the same length wing as the FSII which has a two foot bow tip. The X is stalling at 36mph with power off at 2600 feet ASL. It floats halfway down the 2200 foot grass strip at TNK. I have made about 20 landings without any inidication that the X is going to fall out of the sky at 10 feet above the ground. In ground effect, this airplane floats, even with the chopped off outboard wing tips at this time. It is cruising about 85 mph at 5000 rpm, which is great considering the 3 blade Warp Drive Prop, 70", is pitched very light. I am turning 5400 to 5500 on takeoff. Straight and level it will turn about 5600 rpm. It climbs like a Kolb, flies like a Kolb, and lands like a Kolb. Took a big old rudder trim tab to control adverse yaw created by the 912ULS. We still have to work on the pitch trim system. Need stiffer springs. Tailwheel springs are way too soft for proper ground control. Needs a set of Maule Tailwheel Springs to get the job done. Even better would be a larger tailwheel on this extremely wet and soft field I am flying out of. I have not gotten around to testing the flap system because of extreme turbulence. Soon as we get a break in winds, I'll go to work on that. I am anxious to see what she will slow down to with flaps, then get the droop tips installed and find out how she performs. I'm using my lap top at Travis' desk in the shop. Fingers are turning blue. Time to head back to the 5th wheel and warm up again.

Unless you're acclimated to it. I live at 7000' MSL and recreate from time to time at our ski area which is at 10,000' MSL. I also fly regularly at altitudes right near the SP limit of 10,000' with no detectable affects. The folks in the CO rockies live at even higher altitudes and fly through the passes up there sans O2 at 13,999' MSL all the time..... I'm being a little bit tongue-in-cheek, but I'd still say a large _change_ in altitude over what you're acclimated to is more hazardous without O2, at least until you get to borderline (and legal) limits like 14,000'. The first symptom I have is I start to see spots in front of my eyes, due to the blood vessles in the retina expanding a bit. This is very easy to detect and signals to me that I need to start being careful. I no longer have symptoms at 10,000', but I sure did when I first moved here. I can't legally go any higher than 10,000' in my plane (though I will be able to in a sailplane) so it's not too big of an issue.... Still, advising caution on altitude affects is a good thing....

Subject: Turbocharger on a GEO
Date: Mar 23, 2008
Vic, The turbo I have I got on eBay. I got it off of a Turbo Sales Company in Canada. It is a brand new Garrett GT1544. They sell for about $750-$800 normally. I lucked onto this one, because the seller had a very little reserve, and not very many o ther bidders. Anyway, I got for a grand total of $260 incl. s/h from Canada. The GT1544 is the smallest turbo Garrett makes. See attached photo. It is made for engines in the 800 to 1000cc range. This turbo is quite often used on modified mot orcycles. My application is intended to keep the boost VERY mild. Quite often, race car engine buil ders speak of 20 to 30 psi boost. All I want is 5 psi MAX. This is because; as long as you stay with 5 psi boost, the ECU engine's computer) will make the fuel/air adjustments automatically for you . As I previously elaborated about two months or so back, performance for t he turboGEO puts out 107 lbft of torque @ 3800 rpm. A Rotax 912S has 95 lbft of torque, and tha t happens at 5100 rpm, IIRC. Supposedly, you should be able to throttle down to 3800 to 4000 rpm, crank that electric in-flight adjustable prop to bite more, reduce noise, and INCREASE your fuel burn. T hat is the senario!!! Again, as I also said before, this is what I am told. Since I have not p ersonally verified these figures, they are simply "goals". (that were attained by others, according to them) As far as weight is concerned, I think the whole conversion adds about 16 -18 pounds, for about 30% more power. Darn good trade off, if you ask me. BTW, Jeron, at Raven Redrives, has a bolt-on turbo kit for the 3 cylinder . His turbo is one size up from mine, I believe, using the GT25. $1850 for the whole kit, as I remember. Fuel consumption improves with the turbo, by about .25 to .5 gal/hr., yet power increases by 35%. As always, second hand info is just that, what others say. I cain't swea rs to none of it, lest'in I cun sees it fo ma'seff. Mike Welch ________________________________________________________________________________

Apparently your Kolb does, or did before VG's. I had VGs on my plane for nearly 100hrs. They were effective at reducing stall speed, but were not an improvement to MY plane overall, so I removed them. I agree that they are a great addition to many Kolbs.

R Hankins, You are obviously in denial, to dismiss the many reports of Kolb Drop as incorrectly built planes. That is an pretty widely known characteristic of Kolbs, the fact that you are so closed minded that you are unwilling to see facts is exactly why I would never never take advice from a person like you. Secondly, given that you are the only case I have heard about that actually took VG's off your Kolb, my guess is that you did a very poor job of putting them on. Are you one of the guys that made your own VG's with the " That looks about right " method ? Now I understand why you are so against VG's, looks like you tried them, failed, and now have the " I did not want them anyway " attitude. If you don't want VG's, you most definitely should not have them. There are mountains of information on the benefits of VG's on airplanes and Kolbs. Giving bad advice and bad information on the list just because you were unable to correctly install VG's is what I take issue with.

Build the plane with as little drag as you can, and dont get in a hurry and the Kolb MK III can cruise on very little power. Im betting that using cables and eliminating the aileron tube going out to the wing will help reduce your drag a lot. The efficiency of having EFI on that engine cant hurt either. Don't know if it will be 2 GPH or not, but I bet your fuel usage on a Geo engine will be much lower than the Rotax guys. With my Rotax 912-S I plan around 4 GPH in my MK III at just under 70 MPH and 4200 RPM. My Kolb will do 80 but my fuel burn goes way up and the turbulence gets much worse :( I wish I knew how John H. got 85 MPH cruise out of his MK III, that is really fast !!!

List, FWIW -- I put a STOL mod on my Cessna 170 - this was drooped tips, stall fences, new and blunter leading-edge cuffs and aeliron gap seals, We did careful test flights before & after, and came up with a 4% increase in cruise speeds. (A nice surprise!) Much better stalls and slower flight before stall-warning horn went off. Slower landing speeds and a more solid 'feel' all around. The landing distance needed was reduced by at least 20%. I use slips a lot, and they were unchanged. I regret now that we didn't put on one thing at a time and test each time - but we didn't. I was very pleased with the increased performance. I've also spent some time at 13K and a tad higher. I trim for a gradual descent so if I pass out she should fly to a lower altitude all by herself. She's a very stable craft and flies hands-off almost indefinitely. So I think I'd have a fair chance of surviving, but am glad I never had to have it proven. Simulated no-pilot flights were fine, losing about 200FPM & no tendency to stall or spin. BTW at those altitudes I get a coppery taste in my mouth, but it must just be my personal chemistry. Never met anyone else who reported it. I've been in low-pressure chambers and know that you will have NO warning before passing out from hypoxia. I also had one job that required going from sea level to 13K in the mountains, in one day. I tried to create a polycythemia (ability of blood to carry more oxygen) by running a lot for weeks before the trip. Seemed to work! I'm sure people who live at 5,6, or 7K feet would have less trouble at higher altitudes than us sea-level types. Younger better than older too; no surprise! ________________________________________________________________________________

Thanks for the Report John H , I fell in love with those new wings and droop tips ever since I saw that MK III Xtra at Sun and Fun last year. Increasing wingspan usually improves a planes performance, and from your report it sounds like it is working for the MK III Xtra. I cant wait to hear how it does with the wingtips attached. If your flight tests indicate a major improvement in performance, I will do the work to modify my wings to increase the span and put droop tips on my Kolb. The one thing I was unsure about were the Aileron cables, how do they feel, any feeling of stiffness, or play, or not being up to the job ? On my MK III Xtra, I had a pitch down trim condition and had to change the incidence on my Horizontal Stabilizer to 7.5 degrees down, almost double of what Kolb specifies. I also had to put trim tabs on with a bit of up trim to spread the load over horizontal stab and elevators evenly. It will now fly great with stock springs. Attached are pictures... 85 MPH cruise is fast ! What RPM are you using to cruise at that speed, and what RPM do you climb out at ?? I am looking forward to your report of how much the wingtips help, and also how the plane handles in calm air.

If you are in good health, going over 10,000 feet is not problem. Attached below is a picture of me on my motorcycle at 15,000 feet in South America, the bike which has scary amounts of power would barely run at that altitude, but it got me there :) I stayed at high altitude for days, and I live at sea level.... No ill effects and no problem. I had my Cessna to 150 to 18,000 once, took a couple hours but it got there. Each person is different, many can handle altitude with no problem, many cant.

Mike B" Mike B: If you want the new X wing you will have to build them. They use a 13' main spar instead of an 11'. Probably would not be wise to try and splice two feet of 6" tubing to the end of what you already have. I mentioned cruise and climb rpm in my original post above. I am pleased with the new Morse Cable aileron controls. We are still adjusting attach points on the rear aileron bell crank to get the mechanical advantage to suit me. Seems to me you have probably gone overboard on lowering the leading edge of the horizontal stabilizer. That may be killing your cruise speed. Learning how to set up a Kolb has a lot to do with how it performs. I know of two other MKIII Classics that cruise same as my mkIII. They are also configured the same as mine. One is powered with an 80 and the other with a 100 hp Rotax. If it was my airplane, I'd double up on the pitch trim springs and get the horizontal stabilizer back up a bit. Changing the angle of attack of the horizontal stabilizer also changes the ability of the aircraft to stabilize in cruise flight. When mine is too low, it feels like it is flying on a ball, wanting to slide off fore and aft. Another thing that may be reducing cruise on your airplane is the open area above and behind the cockpit. If you are flying with partial doors, that will also cut cruise. My mkIII is covered from top to bottom and the doors are complete. I am fully enclosed. I have said this many times. Some folks with low time in Kolbs can screw them up so badly they fly like a dog turd. Probably because they think they know how to improve it before they get enough time in it to know the airplane in the first place. Thinking you have a lot of experience in a Kolb is not the same as flying and grinding out those hours. I feel I got to know Kolbs better because I have spent a lot of time flying and experimenting in the air and on the ground with them. It didn't happen because I thought I knew best. It happened because I made a lot of mistakes, did a lot of experimenting on my own, because there was no one else to go to for help. I think Brother Jim and I have done a pretty fair job of learning about these little Kolb airplanes. If not, I would not be flying them today.

I had to weigh it several times, then weighed other stuff for calibration. It weighed the same, every time. I still need a gap seal, but I don't think that will go another pound. Here is what it is: Old model Firestar airframe with the high cockpit sides. Rotax 447 with 2 blade Warp Drive prop. BRS canister under the fuel tank. Full enclosure.

Instruments- alcohol compass, ASI, tach, CHT, altimeter. No flaps, flaperons, brakes, pants, etc. Barn door ailerons. The bulk of the weight difference was removal of the padded wood used to keep the tail from moving in transit. I took off several stray antenna brackets, radio mount, and a strobe and bracket with no power unit. I still have to put in a five gallon overflow on the 10 gallon tank until I change it.

I cut the slits and looked inside today. I was happy to see that everything looked good, and that the later drag strut modification had been installed on my plane. I'm a little unclear, however, just what parts are meant by "lateral bracing". The internal diagonal bracing in the wing ribs? Or something else? From message #17821 by Richard Swiderski: >Re: safety alerts on UltraStar: The front pivot arm that operates the >belcrank has a notice to be reinforced.

I'm not clear which pivot arm this is. I assume it's the arm that transfers the vertical motion of the lower aileron pushrod to fore-and-aft motion of the upper pushrod (that in turn drives the bellcrank that droves the two rear aileron pushrods)? Does anybody have a drawing or photograph of what it should look like after modification? From message #36046 by Richard Swiderski: >If yours is a very early model, make sure it has a steel collar on >the inboard end of the wing spar, much like the collar at the front end of >your boom tube.

I don't appear to have any roll authority issues (though I have nothing to compare it to), but I _do_ have a sleeve that joins the front spars (leading edge tubes) which would tend to help keep the wings from twisting. While I was at it, I moved the rudder cable attachment higher up on the pedals so I can get full rudder deflection with less foot motion (I find it uncomfortable and have been meaning to change this for some time), and fixed some previous owner's strange interpretation of how the seat belt should be attached.

I plan on enclosing that area behind the cockpit with aluminum like you did and putting a V back there to get smoother airflow, I already have the materials, just have not had the time to do it. I have full doors on, just like the configuration you are flying right now. I have tried the Horizontal tail at the 4 degrees, but felt like all the load was on the elevator. My Kolb flew fine both ways, and I did not notice much of a speed change, but I wasn't really looking for that either, so I will have to test fly that again and pay attention to any speed differences. Splicing an extra two feet of spar on is exactly what I was thinking of doing. The stress on the spar towards the wingtips is minimal, I think a well done splice would be more than strong enough to add just two more feet of spar on each tip. I hope the weather improves for you, I am looking forward to hearing more about how your tests are going. Mike -------- "NO FEAR" - If you have no fear you did not go as fast as you could have !!!

Possums- You said you have 8 rib wings. Are you counting the ends? Travis told me not to count the ends, only the full ribs in between. Mine are 27'6", 5 ribs, 3 false ribs in between, and 1 false rib outboard of the last rib. I don't know for sure that they are from a KXP, but assume so because of the mounts being 2 1/2" shorter than a newer Firestar. The rear mount is a big, heavy lug that had to be ground to fit the u-joint. I also had to slide it in about an inch, rotate, and re-drill the hole in the inspection panel in order to get the wings straight. This allowed me to saw off about an inch of the very heavy tube on the lugs with no loss of strength. When I first put the wings on, the tips were forward a couple of inches in a "V" shape. I could have extended the front mount- adding weight- or do what I did, cutting weight. I still have to do a CG, but with the Firestar's large gross weight of 725 I think I have a lot of lee way. One thing I don't like that is not a problem for local flying. I need a box or step ladder to put gas in it. The tank is mounted high, and is hard to access with the wings in the flying position. The tank is still 10 gallon, and I will put a limiting tube in the filler, as suggested by someone on the list. At least until I get a 5 gallon. I don't see an easy way to change the tank. Looks like the cage was built around it- a very tight fit. Looks like more Stits work. Re: Ceiling. I live at 60 feet MSL, and smoke, and am a former welder. I have never (other than an airliner) been above 2000', other than 1/2 hour on Mt. Washington. I guess I'll keep it slow and low- like me, now pushing 60.

As long as you're _absolutely_ certain that you can get the 5 gallon tank in, you could cut the old one up to get it out... -Dana -- "Hiking is just walking where it's ok to pee.....

Dana- I think I will get the tank before I decide what to do. the 10 gallon tank is mounted high, over the BRS. The BRS is fully enclosed, and fires out the side through the fabric. maybe I can access through the seat back, but I think there is a strut in the way.

Jack, I think I just figured out Mike B wing angle setting problem. After talk ing to Brian @ TNK Tech Support, awhile back, he explained to me that with the redesign of the Xtra's wedge nose, this pr oduced a huge "nose down" phenomenon, when compared to higher setting for a Classic, hence the relocation angle of the main wings, compared to a Classic. I am under the impression Mike B's wings are too high, pitching down the fuselage wedge, a nd requiring a significant deviation of the hor. stab.'s angle from normal. The incidence measurements I got from Brian SHOULD be what Mike B's plane should be set at.

Mike B. I just went back and examined your modification to the hor. stab. mount. OH MY GOD!!! You used aluminum (!!!) to relocate that position!! And you had to notch it, to boot. I would red tag your plane immediately, if I was an FAA inspector!! If one of those aluminum straps let go, it would place an enormous amount of twisting force on on the one remaining, with a likely failure of the second one almo st instantaneous. You have been lucky so far, don't push your luck any further. The very LEAST you should have done is make the extension out of 1/8" 413 0 chromoly!! However, it is my opinion you wings are NOT set correctly, and this require d an "odd" hor. stab. setting is the result. You need to set your wings correctly, to within a gnat's ass of perfect, THEN reset the hor. stab. to recommended position. I did a lot of research recently regarding setting up the wings the MkIII (both Classic and Xtra) With my nose redesign on my MkIII I knew this would adversely affect the pr esent position of my current and older incidence setting. I would highly recommend you do yo ur own research to resolve your situation. And, for God's sake, don't fly that sucker until you get it right!! (and get those aluminum straps off!!

John, If I turn on the Pump before the Mains are empty, they will overfill and the excess goes out the vent tube on the bottom on the plane. Other than wasting fuel at almost 4 bucks a gallon, no harm is done. If I forget the valve, the fuel simply wont be drawn by the pump. Not quite as easy as the single large
