It is good to hear that the 582 has enough power for the Mark III. The 582 in my Powered Parachute is OK, but would like more climb when I am 2 up. And mine is considered a lighter PPC, with some of the heavier PPC's out there the climb is even worse. I have the louvers on my grey head 582. It does help me feel better about preventing a cold seizure. -------- Wesley Elliott Sport Pilot-PPC Read this topic online here: http://forums.matronics.com/viewtopic.php?p=391678#391678 ________________________________________________________________________________

I know that this new engine has been talked about in the past, but it seems they have been shipping out alot of them and it looks like they might be around for the longterm. One the viking yahoo forum there is a guy who says he is seriously considering mounting the Viking on a KOLB. Jan- I think it would be great if you looked at the integration of the engine on the 2 place KOLB's. I think it would be an excellent performance fit and I believe the market, especially retrofit, would be at least as large as the SeaRay. I could send you pictures or scanes of the drawings offline. The KOLB factory guys could probably do even better. I am aware of these airplanes with mostly 912's Jabs and 582's, but also 618's, Hirths, Subarus, VW's, and BMW's. I am not aware of any of them using a conventional welded tubing engine mount. They bolted from a bottom framework on the engine essentially at the engine longitudinal CG to 4 Berry/Lord mounts on about a 10 in square horizontal pad at the aft end of the KOLB cage. If there is available structure for that on the Viking it would probably be the most structurally efficient option...especially for those of us with a finished cage and looking at a retrofit from the Rotax configuration. Bob Might be another alternative to the costly 912? -------- Wesley Elliott Sport Pilot-PPC Read this topic online here: http://forums.matronics.com/viewtopic.php?p=391684#391684 ________________________________________________________________________________

No, I am in far Eastern Oregon, and I now have a Firestar II. If you are looking at a specific Mark 3, why not go to the plane that you are thinking of and have him take you for a ride. That way you can see how it works. If you are looking at a kit from Kolb, call Travis and talk to him, he won't steer you wrong. If you are just shopping for the type of plane, perhaps someone will step up and take you for a ride.

Wes You are asking a lot of interesting questions. That's good. A new engine on a airplane is from personal experience a lot of time and effort. Seemed like everything needed to be designed and built for that engine/air frame. Check the engine weight closely, it is real tough to beat the power/weight of a 912. Engine manufacturers are notorious for under reporting their operational weight. Additional weight means less load carrying capacity so you could end up with a single passenger airplane or worse. Engine mounts and exhaust systems are a nightmare and don't expect to have a engine or airplane manufacture to design one for you without a proven market opportunity. Seemingly easy things like prop selection and reduction ratios are very difficult to get right the first or second time. Bottom line it is easy to spend more than the cost of a 912 and not have as good a engine or worse.

It's also good to take a very close look at the vendor. That particular vendor has a long track record (that, with a different name, precedes the Viking project & has a much longer record). Your mission, should you choose to accept it, is to determine what that track record is. Charlie On 01/05/2013 10:15 PM, Rick Neilsen wrote: > Wes > > You are asking a lot of interesting questions.

Rick, ...It seems that the high frequency vibration from these engines causes a bunch of metal fatigue issues withexhaustsystems and other systems on and around these engines. Talk to any 912 driver that has any significant hours on their engines and they will reportsimilarproblems.... A little clarification on this subject is needed. Following is my experience in this regard: I've owned 4 different airplanes with 912 engines. I've also been maintaining several other 912 powered aircraft for about 11 years. Only one of them ever had a cracked exhaust system problem. Allegro 2000 is the one that had regular and continued exhaust system cracking. It was due to crappy materials and design. It had absolutely nothing to do with the engine vibrations. I maintained all of these airplanes so the differences in maintenance was not the cause either. All 4 airplanes had at least several hundred hours on them, but only the Allegro, made in Czech Republic just like the Sport Cruiser, had exhaust system cracking problem. When I took the cracked exhaust system to a highly qualified local welder to repair the first time, he had a hard time welding it. He had never seen any kind of metal like it, ever, and he had been welding anything and everything for over 30 years. After second time it cracked I ordered a new, recently redesigned exhaust piece from the factory. It was so redesigned that it would not fit the old muffler. So I had the old one repaired again and sold the airplane, warning the new owner that he would have exhaust system cracking before long.... and he did. I'm now half owner of a Diamond Katana with Rotax 912-F3 engine which is second 912 engine in this airframe. First one was an A3 model which had about 1500 hours on it when it was swapped for the newer F3 model, which now has 1100+ hours on it. The original exhaust system is still on the airplane and has over 2600 hours on it with no cracks or other issues. There are no differences between the 912UL engines and the type certificated 912F3 engines in internal parts. The only differences are in some external systems such as fuel lines, oil lines, and double carb springs instead of single on the UL, and of course the paper work trail. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 no engine FOR SALE Diamond Katana DA20-A1 Rotax 912 F3 Don't worry about old age... it doesn't last very long. - Anonymous Read this topic online here: http://forums.matronics.com/viewtopic.php?p=391702#391702 ________________________________________________________________________________

There is also an attachment to your cap which ,through a little receiver clipped to the screen enables you to change view by turning your head. Worked for a while then failed and I am not computer savvy enough to sort it out. My control stick has a throttle attached which is fine but it could do with a trimmer. Change of view is controlled by a `hat` on the stick. That is OK. I use the X plane version. This has a weightshift and a Piper Cub at the light aircraft end of the offerings with a nice gentle fly in Cross country and also landing the Cub on the top of a moving van.

Thanks for your reply Shack! I hate it when someone asks a question then argues with someone who answers him! This isn't my intent here. Since this is a public forum and we have a public conversation here I am citing some information that I have collected from good sources, simply to keep the lurkers from making wrong decisions. > Too heavy for FS I. I have been wondering about this. Reason I was considering it is that the FS has a reasonably good gross weight (which I forget), and with not all that many structural changes it became a 2-place. The wings are not as strong as the 2-place but they are about the same sq footage. That being said, I have no clue if it is *really* too heavy. My 503 weighs about 98 lbs. The 084 weighs 127 lbs complete with prop in a typical setup. The 084 would be operated direct-drive. At the slow speeds of the FS-I, I think the advantage goes to the 503 with the gear reduction unit. > Who said 50 hp?

Note that we free up some serious hp when we remove the huge cooling fan. Also, remember I said that the 084 cab 'built' to about 50 hp.

Just a few more thoughts. The RPMs listed are real close to my direct drive VW. Thrust is what makes a airplane fly, that and MONEY. The horse power needs to be converted to thrust and at a 3600 working RPM you are restricted to a small prop somewhere around 58" or less. The general rule is the bigger the prop the more HP is turned into thrust until the prop tips go supersonic.. My direct drive VW used to turn a good portion of its power into noise instead of thrust. Also the rated max torque is at 2000 RPM. I configured my latest VW to have maximum torque in the cruise to takeoff RPM range. Unlike a car a aircraft engine doesn't need very much torque at low RPMs but does require the most torque at cruise and takeoff RPMs. Rick Neilsen Redrive VW Powered MKIIIC On Tue, Jan 8, 2013 at 4:11 AM, GeoB wrote: > > Thanks for your reply Shack! > > I hate it when someone asks a question then argues with someone who > answers him!

=C2-=C2-=C2-ENGINE Q&A=C2-- your engine questions investigated Experimenter - November 95=C2-Q.=C2-=C2-Dear Engine Q&A - To answer t he questions about engine horsepower ratings=C2-in the September EXPERIME NTER, I can suggest some rules of thumb that I have heard through the years . They seem to be good approximations.1) To get the effective prop swinging horsepower for small direct drive four-cycle engines, divide the cubic inc hes by two. That makes an O-200 Continental a 100 horse engine. The hopeles sly weak Corvair rated at 150 hp in a car has 145 cubic inches like the 65 hp Lycoming, and that=99s about all it can do. The 750 cubic Hisso en gine is rated at 150 horses but has an effective propeller power of 375 hp. That=99s why it can turn an eight-foot propeller and fly a big airpl ane that a 150 hp Lycoming can barely taxi. The source of this rule was Hob art Sorrell (now deceased) of Tenino, Washington. His crafty wits produced the Guppy biplane that flew on a Cushman golf cart engine.2) Using the effe ctive power described above, you can multiply times 4-1/4 to get the approximate thrust with typ ical propeller efficiency of 85%. Source of this rule was John Thorp (decea sed) of the T-18. See "Cowling and Cooling of Engines" which appeared in SP ORT AVIATION some years ago (Ed. Note: This series appeared in the November and December 1963 issues).Hopefully, these two have left a legacy that we can all use. When a reduction gear is applied to the engine, the effective power is multiplied by the gear ratio.I haven=99t tried to extrapolat e the formula to two stroke engines because I have very little experience w ith them. I can=99t tell what the effective power is of the little 70 horse drone engine that one sees buzzing away on a Bensen Gyrocopter for i nstance.Yours truly - Bertran Copp, Monmouth, OregonQ.=C2-=C2-Dear Mary - In the September 1995 EXPERIMENTER, Jim Delaney of Coralville,=C2-Iowa asks whether a Continental A-65, a 65 hp Rotax and a 65 hp Volkswagen all produce the same thrust. Assuming the same airplane and properly matched propeller/engine/a irplane combination for best cruise, the answer is yes, theoretically. Prop eller efficiency differences will produce the only variation in performance . This usually amounts to only 2 or 3%. Thus, horsepower is a valid method of comparison for correctly matched propellers because thrust is directly r elated to horsepower.Often static thrust is erroneously thought to be an in dicator of flight performance. A propeller designed for maximum static thru st will severely limit cruise speed. This type of design is only suitable f or helicopter rotors. It is an over-simplification if applied to airplanes. Proper propeller design involves matching thrust to drag and finding the b est cruise to climb tradeoff. Putting it all together involves difficult an d tedious calculations. I am a consulting aeronautical engineer and author of a computer program called "prop optimizer" that matches propeller to engine and airplane automatically.Many design studies I have done indic ate that there is an optimum propeller size and rpm for any engine/airplane combination. Airplanes, even of one design, can vary considerably in drag due to manufacturing differences. Therefore, if best performance is desired , the propeller should be individually matched for each airplane. Specific questions may be directed to me at 916/622-1886.Sincerely - Don Bates, Plac erville, CaliforniaQ.=C2-=C2-Dear Engine Q&A - I would like to know if there is a four-stroke engine out there in the=C2-65 hp range that would work on my new S-12XL, other than the Rotax 912 - one that doesn=99t require a second mortgage to purchase.The RANS S-12XL is an excellent aircr aft, I believe.

The only two engine s that I know of that might work are the new Yamaha four-stroke engine, whi ch is unavailable at this time, and the Moto Guzzi, which is unproven on a pusher aircraft.

Should it have been . 00436 and not .000436?I am building a Pober Pixie lookalike under our 95/10 category and will be powering it with a Subaru EA 81 imported from Japan w ith approximately 34,000 miles on it.

However, I will need a thrust bearing and propeller extensio n. Could you please advise me where I can obtain these.I also believe with this combination I should get in the vicinity of 70 hp. Is this correct?Tha nking you once again for all your help in the past and looking forward to m eeting you maybe one day at Oshkosh if we can make it again.

Your Pober Pixie=C2-lookalike is going to be a good looking aircraft. There=99s so many different aircraft to choo se from, it=99s hard to select one you would really like.Regarding th e Hitachi carburetor, it will work fine.

If you look at them both together, you=99ll use the differe nce. You=99ll need more air to give more perforrmance because you =99re running the engine at a higher rpm. The engine has to breathe.Rega rding the thrust bearing, I don=99t think you=99ll need one. On the 52 x 26 you should get about 3600 rpm at about 60 or more hp because t he engine doesn=99t get into the power curve, but you should get 325 - 330 lbs. of thrust.What kind of prop adapter are you using. If you don =99t have one, you need to get one that you can drill a hole in the cent er and tap the crank shaft to make a good secure connection.The comment on tip speed on prop was made by Ed Sterba and I can=99t answer that (Ed . Note: Yes, you=99re right, the figure should have been .00436 - we apologize for this error and any confusion this has caused our readers.

Feel free to write any time.Yours truly - DonQ.=C2-=C2-Greetings, Don - I=99ve found your work very informa tive and wonder if I could avail myself=C2-of some of your information se rvices, while keeping same as short as possible.I=99ve always been im pressed with the formula for torque, rather than horsepower. In endeavoring to keep a Subaru conversion as simple as possible the thought occurred to me to try drive direct and with half rpms. I=99ve often thought about a blower but with enough input, like a unit from an emission system, to ke ep a plenum full of intake air. Possibly a special cam shape may help in im proving induction while exhausting more fully.I realize this sounds extreme , but it appears the engine has enough flywheel weight to ensure smooth run ning at low rpms. And, with the extant oil pump, has any thought been given to oil cooling? I would imagin e any number of highly developed oil coolers might be available cheaply off of unused large airplane engines.Any thought or information in this very c onceptual stage will be greatly appreciated. By the same token, if you have any special interests, I=99d appreciate knowing them.All the best - Norman Benedict, Santa Maria, CaliforniaA.=C2-=C2-Dear Norman - Nice re ceiving your letter and the interest in Subaru powerplant conversions. If y ou use the EA-81 for small aircraft, straight drive, a 54 x 26 prop would g ive you 325 lbs. of thrust in the pusher type. You didn=99t mention t he aircraft you wanted to use. I have no idea what horsepower you want, so we=99ll cover all the bases.EA-81 - 72 hp (ideal for small aircraft). With drive would give around 450-475 lbs. of thrust with a 2.2:1 ratio. We ight with redrive 180 lbs.Legacy - 130 hp, straight drive would give you 45 0-475 lbs. of thrust. With redrive, 550-570 lbs. of thrust with a 2.1:1 ratio. The weigh t of the Legacy with drive would range from 180-210 lbs.Oil coolers have be en used on Subarus and are easy to hook up. There are discharge fittings on oil pumps that you can use.I hope I=99ve helped you. - DonQ.=C2- =C2-Dear Don - I have read with great interest the various responses to l etters in the=C2-EXPERIMENTER concerning the use of Subaru engines in hom ebuilt aircraft, and you obviously have an extensive knowledge of these pow erplants.In the November 1994 issue of EXPERIMENTER there was a table publi shed which defined general engine specifications, which I must assume was f rom official Subaru sources.When I study the table, I find that the highest horsepower developed by an EA-81 OHC engines in naturally aspirated forms do not achieve close to the advertised 98/100 hp advertised by all the majo r Subaru engine convertors for the EA-81.Any ideas how this massive discrep ancy occurs other than a communal dose of advertising licence?I have already ordered a converted EA-81 engine (SHO) version from what I judge as a professional e ngineer to be the premium quality source, but I will most certainly be very pleasantly surprised if the actual power output is in excess of 100 rather than the advertised 118 hp. Your article appeared two months after I had p laced my order after much deliberation on the relative merits of the Subaru versus the Rotax 912 or 914.Incidentally, there would appear to be equal o ptimism regarding fuel consumption of Rotax engines. A study of the genuine Rotax fuel flow charts will quickly reveal that one would have to lean the mixture to unburnable ratios to achieve the popular quoted figures. It was quite refreshing to read a report in the latest issue of KITPLANES of a fl ight test of the 914 in the Pelican which quoted realistic fuel consumption figures which do match the fuel burn rates shown on the Rotax charts for this engine.Any comments would be most welcome.Yours sincerely - Fred H. Tayler, Hoffman Estates, ILA.=C2-=C2-Dear Fred - Was nice rec eiving your letter and very interesting. The EA-81 engines=C2-that they a dvertise with higher horsepower is accomplished by different cams, shaving heads and polishing intake and exhaust ports,and sometimes increasing the s ize of pistons. That=99s how they accomplish the claimed horsepower.T he fuel consumption of the Rotax engine probably involves an in-cockpit adj ustment for the carburetor to lean out for better fuel consumption.

I had a 4ao32 and a 4a084. I put a belt drive on the 32 and ran it on a mobile test cart [prop driven] Anemic at best. Would make a very good engine for a very large RC plane. Also put the 84 on the cart, direct drive. Better, but still weak. I got rid of all the cooling tin, the cooling fan, and the shielding on the spark plug wires. I think weight was less than 120 something. We tried several different carbs; none helped much. Sure, the 84 is flying on some planes, but I doubt any are flying out of a short field. Climb rate will be poor compared to a 503.[Even if it were 50 hp.] If I were to put one on a plane, it would probably be on a lightly built Minimax. Beef up the nose a little. Paint up the engine real nice. Put on an efficient wood prop. Tractor config. is much better at cooling than pusher.[without adding any cowling]. I had a nice FS II w/ 503, just recently sold it. Getting older and dumber meant it was time to get out. Have fun with the 84, just don't expect too much. Shack ________________________________________________________________________________

> a 3600 working RPM you arerestrictedto a small prop Thanks Rick. This is maybe the biggest draw-back. And with this engine it is a really big deal to attempt to raise the rpm of torque peak, unless I use EFI.. which will help there given I replace the entire intake manifold. I like doing/planning engine mods, done that for like 45 years. I have a coupla Generac engines I plan to modi-fly, I'd rather express myself there. I wonder about the over-heating issue I have been told about. Sure, more power generally means more heat. So, if I raise my CR I add to the thermal loading of the engine, IN THEORY. But since higher CR adds power and efficiency (or just efficiency which effects power), why couldn't I just back off the throttle a tad and lower the thermal loading? Should give greater available power for a short time plus yield better mpg. I think. I am actively soliciting comments on this idea. Sure, at full throttle the EFI will produce more heat also but I don't want a setup that requires full throttle all the time.

Gotta respond to these thoughts of small engines on kolbs Been flying these little buggers from abt 1993. I feel mpg is important but when I hit a sinker, downdraft, sudden tailwind or just plain nasty wind I am mighty glad I have some reserve power to save my butt. We played with most all those cart and industrial engines and pretty much came to the conclusion we wanted strong, fast and reliable power plants. This dicussion might get some newbies thinking they should put their lawn mower engine on a kolb and die for it. While it may be perfectly fine for you expert engineers to configure a five horse briggs to fly do not encourage the average dude to try it. I would not want that on my head. Make sure they understand the ramifications of engine failure in flight and lack of power in emergencies. My opinion.

This could be an interesting development. New Rotary Engine From Austro Diamond Aircraft's Austro Engines has bench tested a new dual FADEC-controlled rotary aircraft engine, the AE80R, that aims to match a weight of 60 pounds with a power output of 80 hp. The engine has been in development for more than two years and builds on Austro's experience with the AE50R 55-hp rotary engine but has differences in its internal design that incorporates a "no loss lubrication system." The new engine is targeting the LSA and ultralight aircraft markets, and may also see use in unmanned aircraft. Austro Christian Dries, chairman and owner of Diamond Aircraft, which owns Austro, says the new engine "has no vibration" and is a good fit for weight-sensitive small aircraft. According to Diamond, the dual FADEC system will keep fuel consumption at its lowest possible limits and the engine oil system will result in extremely low oil consumption, maximizing its efficiency. Austro Engine last summer pursued airframe manufacturers other than Diamond, seeking potential matches for its diesel engines, which it sees as a growing segment in European aircraft markets. The company already offers diesel and rotary style engines. Austro's recent production of AE50-series rotary engines has been close to 125 engines per year. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 no engine FOR SALE Diamond Katana DA20-A1 Rotax 912 F3 Don't worry about old age... it doesn't last very long. - Anonymous Read this topic online here: http://forums.matronics.com/viewtopic.php?p=391973#391973 ________________________________________________________________________________

If the Aircraft Rotary engine is anything like the Mazda Rotary engine then this will be a great engine, perhaps better than the Rotax. I used to have a Mazda RX3, it was great!

Re the Rotary engine, I ran a Ro80 with a Wankel Rotary for a couple of years. Ultra smooth and it would run on almost any grade of fuel I liked it very much. However I hope things have improved technically. Fuel consumption was high, around 22 mpg when a similar car would have been 32 mph. Starting problems became a major set back and the oil consumption was unbelievable. I visited a local Air and Transport Museum a few years agoI was surprised to find my old car on display.

Attached are two pictures of my neighbor's AO42 twin mounted on a trike frame. Not flown yet, I'll keep you posted. One of the difficulties on mounting it on a stock Kolb is obvious, that deep oil pan. Pat tells me the engine is 84 lb. as pictured. Just a guess but if you were to get rid of the mag and replace with the ignition system used on the big Briggs and Stratton twins (with some rework) you could knock another 6 or 7 pounds off it.

Subject: Newbie Question - Kolb MK III Extra or Kolb IV
From: "DGaudette" <gyrodoug(at)woh.rr.com>
Date: Jan 15, 2013
Hello. I'm a former Glider/G.A./Gyro pilot looking to get a taildragger. I'm considering both a Kolb MK III Extra AND a Kitfox IV. I just can't find anywhere where someone has compared the two. Any advice? I'm specifically looking at the KF, Kolb or Avid because when I owned a Gyroplane, I trailered it to/from my local airport 3 miles away. I kept it in my barn and avoided hanger fees etc. Any thoughts folks? Thanks.

Was wondering how hard it would be to replace a 582 with a 912 on a Mark III? Just curious as to the level of difficulty.... -------- Wesley Elliott The 912 and 582 bolt up the same. Kolb Aircraft can provide parts and technical advice. I initially powered my mkIII with a 582, then repowered with 912. Was a little more difficult to transition back then. We had to design engine mounts, radiator and oil cooler mounts, exhaust system, and reverse throttle control geometry. The 582 pulls throttle open. The 912 pulls throttle closed. Was worth the effort. john h mkIII Woodville, FL ________________________________________________________________________________

Need help understanding the 912 uls generating sys. looking at page 17-1 fig 29 of the rotax install manual. I need to know if i can check for voltage between one of the yellow (ge) wires and ground, or between the two yellow wires , and if so what should the voltage be. What does the 2,5 and a little square box repesent in the wires going to the G terminals on the rectifier? What is # 11 in fig 29 if it is a diode , what kind and where can i find one. my engine was removed from a wrecked plane and i don't think the hookup used the capaciator or whatever #11 is that is shown in fig 29. thanks to anyone that can help me.

Same as the yellow wires on other Rotaxing engines.. the two yellow wires are the alternator output...AC , whose frequency varies with rpm's. There should be no short to ground when measuring each yellow wire..

Lots on the net... the output is two yellow wires...shielded...and they go to the reg/rect the inputs which are normally shown with a sign wave inscription .. Rotax choses to mark those with a "G". The + or output goes to a filter cap and a slow blow fuse...30 amp... and on to the plus side of the battery....normally found at the starter solenoid...Capacitor is 22k ufd or there bouts...not critical..just there for noise transients..

No, the ignition system is completely self generating and redundant (two separate ignition systems). 912 series engines - circuit A fires 1-2 top 3-4 bottom plugs circuit B fires 1-2 bottom 3-4 top plugs 914 series engines - A fires all top, B fires all bottom plugs <http://www.rotax-aircraft-engines.com/a_searchdoc.aspx> <http://www.rotax-aircraft-engines.com/a_searchdoc.aspx> [] how does the electronic ignition work (basic description)? Rotating magnets in the flywheel generate power as they pass over coil windings on the stator. The power generated is stored in capacitors in the SMD modules until the =93triggers=94 send a signal to the capacitor which then passes the power to the secondary coils, which increase the voltage and send it, via the ignition cables, to the spark plugs. [] generator / regulator Regulators need cooling - mounting in the engine bay is not a good idea and can cause premature failure. The regulator output is 250W at 5500rpm. The output is less at cruise rpms. Do not overload the electrical system - items such as electrically heated clothing put high demands on the charging system. Here is some trouble shooting info on the 912...Charging system...Herb 914 engines rely on the electrical system for the fuel pumps. Improper installation or overloading of the charging system should be avoided. Problem: Battery not charging (I.e. Low voltage) Solutions: Remove the yellow wires and check the resistance between them is 0.3 - 0.8 ohms. If the resistance is infinity then you have a broken wire (open circuit). Re-install the yellow wires, run engine at idle and check output form yellow wires (should be 18-20 AC volts). Check output from B+ terminal or regulator, should be 14 DC volts - check the battery is charged - the regulator needs to be connected to a charged battery to energise it. Problem: The generator is putting out AC volts but the Regulator is not putting out more than battery voltage - regulator is faulty. Solution: Replace the regulator Problem: The generator is not producing AC volts, the stator wiring is faulty. Solution: Check / replace the stator wiring. Replace the stator. Check grounds on Regulator & engine block before ordering new parts! Check your wiring if you fail more than one regulator - faulty regulators are not common but crossed wires are! ________________________________________________________________________________

Kolb Friends - Been flying my Mark-3 for a while now (2002), and over the years have strived tried to clean up various airframe details to reduce drag. (Stuff like aileron gap seals, gear leg fairings, etc.) My Kolb requires aileron trim, for straight-and-level flight. I currently use the proven "John Hauck" method for aileron trim - a bungee around the control stick, pulling the stick to one side. Works great, and is cockpit adjustable. But I've been thinking of "upgrading" this system in favor of a proper trim tab on one of the ailerons, to fix my trim requirement. I've been wondering this: Would installing an aileron trim tab cause any MORE or LESS drag than the bungee cord system? Intuitively, I think the drag effect would be equal. But I wanted to hear what the more-experienced minds of my fellow Kolb folk think. Many thanks - Dennis Kirby Mark-3, 912ul, Powerfin-72 in Sandia Park, NM ________________________________________________________________________________

My Firefly needed aileron trim as well. It was only a problem at full or cruise throttle settings so may be a P-Factor thing. At reduced throttle and approach speeds, the ailerons felt fine. I opted for a trim tab because I don't have much room in my cockpit area. I noticed an immediate improvement. The angle on the tab was a guess to start with and I just used test flights to get it dialed in. It's attached with #6 screws right now. I'm pretty much there now and it ended up at the same angle as my rudder tab. I think it's in the neighborhood of 22 to 25 degrees. I'll attach it permanently after I paint it....next spring. It's the dead of winter here right now. My tab is the width of 1 rib bay but a longer narrower tab could be used and would give more attach points if you so desired. I was scared while drilling the ribs that the drill bit would slip and I would ruin my cover job but managed without incident. Just slow and careful is the rule here with new bullet tip drill bit. In conclusion, I'm glad I did it. My only regret is that I needed a tab at all. Was it a building error or P-factor? I'm don't know but am not gointg to worry about it. The plane flies well now. It's possible I may have lost a mph or 2 but my firefly is so light and quick that I can't tell for sure since I'm affected by winds more than you. I have an install picture but am having trouble getting it small enough to post here. I'll work on that. Meanwhile, I can E-mail one to you if you are interested. -------- Gregg Kaat 2011 Firefly Read this topic online here: http://forums.matronics.com/viewtopic.php?p=392578#392578 ________________________________________________________________________________

Not sure what you meant by elevator up or down. This is an aileron trim tab. I determined what direction the ailerons needed to move before I made the tab to achieve the desired trim. The tab can be mounted up or down as long as the proper aileron side is chosen to do the type of mount you desire and the aileron deflects in the direction desired. In my case, I would achieve the same result with a downward pointing tab mounted on the opposite aileron. It may be a matter of what is more visually appealing to a person. The plane has already flown in the current configuration and my trim problem was solved. I just haven't got it mounted permanently yet. It's possible that a tab may work better in one configuration as compared with the other but an engineer would have to help with that.

My Ultrastar was off in roll trim when I bought it. The top cross tube on the cage was visibly bent, not enough to be unsafe but enough to reduce the left wing incidence. I fixed it by making a new universal joint block (on the US the U-joint is at the main spar) with one hole offset about 1/8". Now the wings are even and the plane flies straight. My point in relating this is that if the roll trim is off, this is a simple way to fix it without adding a trim tab. -Dana -- The only correct outcome to an armed robbery attempt is a dead armed robber. ________________________________________________________________________________

To diagnose the reason for need of an aileron trim tab, beg/buy/borrow a digital level and tape it to a straight 5-foot wooden furring strip. If you have a problem that requires aileron trim; the reason is that either that the wing has a built-in twist or there is a slight difference in incidence between the two wings. Digital levels are neat because you can zero at any point and directly observe any difference when checking incidence at any point along the wing. I have seen a lot of wings with an unintentional built-in twist. If both wings were built with the same degree of twist, you would probably never know the difference. The problem is that if your construction table has a built-in twist, your two wings will be built with a twist in the opposite direction of each other; guaranteeing a roll trim problem. I was lucky to have acquired a digital level to set up a table for wing assembly. I was also lucky to have a cast iron bench and two long lengths of straight 3 x 3 square tubing to form a base for my plywood table. For anything lass rigid, during wing assembly, you need to recheck the table each day end-for-end to make sure one of your kids didnt bump the table. Also, there is nothing better than using a digital level when drilling that final hole at the wig root tab that sets wing incidence forever. -------- Jerry King Read this topic online here: http://forums.matronics.com/viewtopic.php?p=392631#392631 ________________________________________________________________________________

It's certainly possible that one or the other wing could have a twist. This was my first aircraft build. The wing halves were actually built in a bedroom of my house last winter on a set of heavy sawhorses. My basement has a 90 deg turn in the stairway so couldn't get wings built down there. I actually had to bring my drag struts through the window for install since they had to fit through a little guide tube on the inboard steel ribs. My leading edges on the wings line up perfectly and of course the trailing edges attach at the U joint. Doesn't mean that there still couldn't be a problem with incidence. I can even see how twist could be induced during the covering process with too much shrinking. I think I could fix an incidence problem using Dana's method but twist sounds like a teardown to me. The plane flies well now with the tab so I'll start the summer with that and then look into seeing if I can fix anything. The key will be if I go to a get together somewhere and somebody can give me some help looking it over. -------- Gregg Kaat 2011 Firefly Read this topic online here: http://forums.matronics.com/viewtopic.php?p=392635#392635 Attachments: http://forums.matronics.com//files/p9150073_193.jpg ________________________________________________________________________________

Most airplanes use trim tabs on all three axes. I have a rudder trim tab on my MKIII. Pitch and roll trim pressures are relieved with forced trim. My Ultrastar and Firestar had tabs on all three axes. There are many, many things that can cause a wing to fly more or less than its partner.

Hi Beauford, your mention of the flying qualities of an 8x4 plywood sheet,plus the foot of snow outside my window at the moment reminded me of this. Many years ago, certainly 50, we had a long and hard winter (by UK standards). Snow was deep and persisted for some time. I lived at the edge of Salisbury Plain with lovely snow covered slopes. The family ran a builders merchant so with a couple of small hardboard sheets, about 4x2 , pinched from stock, my brother and I launched ourselves across the snow. In a sitting position with a bit of sash cord holding the leading edge up we proved the theory sound.. Next question. Will it be better with a larger board?. Will we go faster lying down.? In increments we increased the board size until we arrived at 8ftx4ft board, and a prone position holding up the leading edge with our hands. In the meantime the snow had hardened, become more icy, and more slippery. I launched from farther up the hill than ever before and immediately hit the highest speed yet. Also on the larger board I could not drag my toes in the snow to brake. Speed built up, the bumps seemed to flatten out, I was holding the leading edge up and sure enough, up she came.Flipped into a roll and dumped me on my back going a rate of knots. The board disappeared down the hill. Nothing was broken but we confined our efforts to a 6x4 board afterwards. I wish I still had that body which just bounced. If I did it now I would be in hospital for a couple of weeks. Happy days Pat ________________________________________________________________________________

Well yes, the safest way to transport a Kolb is to fly it home; however it may not be the safest for YOU. You need time to get accustomed to the plane, not to mention freezing URASS off this time of year. The problem with trailers is that the suspension is way too rigid and it transfers all shock loads directly to the airframe. Successful trailering requires a well thought plan. To trailer any distance at all, the wings need to be removed, tied to the trailer walls and hung in a sling to support them at the leading edge to spread the load. The tail boom requires a padded support such as shown in the Kolb construction manual. Where is your Kolb going to live? Kolbs fold easily, and the trailer can make a fine home if you do not have access to a hangar.

The airplane flies square in the bubble hands off, but it did still require a small trim tab on one aileron. No longer required one on the rudder, the spar bracket adjustment made that one unnecessary. As a side note, by adding some dihedral, a FSII can readily be trimmed to fly hands off. Dihedral does not enable a MKIII to do this. -------- Richard Pike Kolb MKIII N420P (420ldPoops) richard (at) bcchapel(dot)org Kingsport, TN 3TN0 Now faith is the substance of things hoped for, the evidence of things not seen.

It seems there is a lot of trouble involved with getting cabin heat into the Kolb. What about 12V seat heaters? Anyone tried it? http://www.activheat.com/index_files/heatedcarseatcover.htm -------- Wesley Elliott Sport Pilot-PPC This Alabama boy made several flights, in his MKIII, to the Arctic regions of Alaska and Canada where he experienced freezing temps during the Summer months. First flight north was without cabin heat. Piled on layers of clothes and drove on. Of course, I was a youngster of 55. After the first flight, I discovered the Chilli Vest. 12VDC powered off the aircraft battery. The Chilli Vest kept me warm enough to fly with far less clothing. My hands and feet stayed comfortable. Ten years after the first flight to Alaska I made my last flight north at the ripe old age of 65. The Chilli Vest did its job again. http://www.sargentcycle.com/chillivest.htm I haven't used mine is a long time. Afraid to try it on. It was a little snug last time I wore it. Good idea to buy a size larger than you think you need. Remember, your body grows as you add thermal underwear, sweater, sweat shirt, etc, and with age. john h mkIII Titus, Alabama - Fair weather flyer. ________________________________________________________________________________

Well yes, the safest way to transport a Kolb is to fly it home; however it may not be the safest for YOU. You need time to get accustomed to the plane, n ot to mention freezing URASS off this time of year. The problem with trailers is that the suspension is way too rigid and it transfers all shock loads directly to the airframe. Successful trailering requires a well thought plan. To trailer any distance at all, the wings ne ed to be removed, tied to the trailer walls and hung in a sling to support them a t the leading edge to spread the load. The tail boom requires a padded support s uch as shown in the Kolb construction manual. Where is your Kolb going to live? Kolbs fold easily, and the trailer can m ake a fine home if you do not have access to a hangar.

Do you need to improve the roll function or the flap function? I have given alot of thought to improving roll but I would not want to increase drag. I think a firefly with 1% more drag could be renamed cinder block. Of course improving roll will create some added drag , my thought was to leave deflection as is and add an inch or two to the flaperon cord. But this might induce flutter. Far to many projects to try it now , at some point in the future I hope to build new flaperons and give it a try.

Heater and Thermostat information. Here is information on a thermostat and heater. Works great and only pulls 40 watts max =2.5amp. Thermostat article from John Gilpin at stolspeed.com. Thermostat at radiator inlet, no more tape or louvers for the radiator on engines that run cold. And it helps the engine warm up a little faster, not a lot faster. But maintains stable temps of 165 winter and 195 summer with the 180 degree thermostat. http://shop.watt-man.com/Thermo-Bob-1-Universal-Kit-with-One-Inch-Fittings-TB1.htm Heater is an oil cooler with fan that moves lots of air and it will remove a fingertip so keep hands clear. Use a DPDT switch and it can be wired reversing so on a Kolbra put it between pilot and passenger and reverse as needed. Tee into the radiator hoses between the engine and thermostat for consistant warm water, I used copper water fittings to make what I needed. Will work on 583 also. I suggest using the above thermostat even on 583 as with the bypass maybe it can help with cold seizures on those engines since it will never be completely closed? I mounted it below the seat and just blow forward or back depending on who needs the heat. With a sealed cabin I only run it less than 5-10% of the time when in the low 30's. Small 6"x6"x4"and lightweight. 1/2" heater hose I used but could probably be smaller since the engine with the thermostat runs 165 consistent on these cold days. http://www.amazon.com/Northern-HURRICANE-Oil-Cooler-Cooling/dp/B005UO2NI8 Have a great day and now I fly no matter how cold it is.

Since you have an Airworthiness Certificate I think there is hope. The N-Number is nothing more than a $5 fee to the FAA. The AIRWORTHINESS CERTIFICATE is the one thats hard to get. I ran across this on another forum. "So, if you don't re-register and you lose your N-number, you should still be able to get your aircraft re-instated. You'd have to register it and, if more than 90 days past due, it would be registered under a new N-number. You would then have to take your AWC and Ops Limits to the FSDO and have them re-issued under the new N-number. It shouldn't be anymore complicated than getting new paperwork after changing the N-number to a unique number (vanity number.) (I've done that. It's not too much trouble to do." Now, if it was the other way around and you only had an N number and NO Airworthiness Cert, you would be screwed. Only route then would be Experimental Exhibition.

Rick, You are right on those E-LSA's that were given an Airworthiness Cert that expired. If his Airworthiness Cert has an "unlimited" for the expiration which most do, I still think he will be just fine. The only thing that he needs is an N number. Not hard to get. I believe the ones that have an expiration on them had until Jan 1 2010 to make them unlimited, and that date has passed also.

Hey Guys, Thanks for the help. Just to be clear, the Airworthiness Certificate is EAB issued in March of '07 with an UNLIMITED Expiry Date. It does include the old N Number which the previous owner transferred to another airplane. I already have my new N Number reserved. So, it looks like I'll just have to wrestle through the process with the FSDO. Hope it won't be too painful.

Wes, It's a free country, you can think what you want, but the Light Sport Branch is using the logic that registration is a requirement for issuing an experimental Certificate of Airworthiness and if the registration expires, since there is NO paperwork path available for re-registration, the CoA then becomes void. I have tried to get the EAA, the AOPA, and the FAA legal council in Washington DC to address this to no avail. That's the interpretation and that's what happens. Again, I urge you to call the Light Sport Branch and verify it for yourself, perhaps the interpretation has changed.

I've no doubt that, right now, many of the components could be printed .... e.g. ribs... (Some, probably not so much, e.g., sails.) But it would be cool to have a 3D printer that, using a composite formula, would print the whole thing, from bottom to top, excluding non-printable stuff like sails, tires, etc.. I would think that, in theory, you could make something much, much lighter, in sum, than the lightest (in sum) UL currently made by conventional methods.

Robert, what I find incredible is that it is possible to print a WORKING model.. I saw a guy on TV copy an adjustable spanner (What you call a wrench I believe) and it featured a knurled nut to obtain the adjustment. At the last moment someone asked for the nut to be a different colour, Sure enough the finished copy not only was delivered with the nut in red and the rest of the spanner in silver but the nut WORKED and the spanner could be adjusted in the normal way. Also on TV I saw a small model with a multiple rolling leg design.It was 8/9 inches long and had a body about 4inches by 4.It looked like a design for a moon explorer. It came straight from the 3D printer.It then had a small fan attached. When the presenter blew on the fan it turned a gear train which drove an axle to which the legs were attached and the damn thing moved forward. There must have been 25 or 30 working joints on this thing and they all flexed and hinged as if assembled from separate pieces.This was STRAIGHT FROM THE PRINTER. Unbelievable.

Yes, I've seen the spanner demo... I've seen some incredible examples, one of a hollow sphere inside a hollow sphere inside a hollow sphere, with each sphere exquisitely "carved", something that would be truly impossible to do any other way. So, yeah, doing the impossible is why this is such an incredible technology. I think the next step is the ability to extrude different materials -- each with unique properties -- so that when printing, unique capabilities can be added... things like bearings, ceramic cylinders, etc. When we get to that stage, then people won't have to buy small appliances any longer, they'll just buy the "plans", it'll be downloaded into the home-3D-printer, and the appliance will simply be printed. (Ideally, old appliances can be de-constituted into its component parts, and the material re-used into the next appliance.) I do wonder if we'll ever be able to print a working engine... but if ceramics can be extruded, I can't think of why not. And, with enough resolution and control, sails should be able to be printed, too. So, my guess is about 15 years from now, for a fully printable aircraft. If only we could print gasoline/petrol! haha. -- R On Wed, Jan 23, 2013 at 9:54 AM, Pat Ladd wrote: > ** > Robert, > what I find incredible is that it is possible to print a WORKING model.. > > I saw a guy on TV copy an adjustable spanner (What you call a wrench I > believe) and it featured a knurled nut to obtain the adjustment.

Subject: Re: Confused about FAA Registration ... From: Richard Girard Wes, Most of what you say is true, unless your airplane is E-LSA and not derived from an S-LSA airplane (like the RV-12) or demoted from an S-LSA when the manufacturer went out of business. If you let your registration expire on an E-LSA that was registered during the grandfathering phase of starting up LSA there is no way to go back and re-register. Why, because 21.191 i(1) expired on 1-31-2008. The version of form 8088A that was used during the grandfathering period to apply for registration expired then, too. I'm sure the good folks at the Light Sport Branch of the FAA in Oklahoma City are tired of confirming it, but you can call them and check it out. Rick, This has come up in the past regarding E-LSA registration expiring. I just talked to Tim Bogenhagen at EAA, and he told me this is not so. If you are the owner of an expired E-LSA, you simply have to send in form 8050-1. He said since you already own the plane, you do not have to submit form 8050-2 or show evidence of ownership. Whats more, he said if you purchase the plane with an expired N-number, you can submit "its equivalent" to evidence of ownership, as prescribed in part 47, and on the instructions of form 8050-1. I am certainly no expert on issues with the FAA, and I know that the EAA is not perfect, but he sounded like he's been down this path before. I encourage people to always do their own leg work and take info on forums with a grain of salt. As you said, call the FAA.

A downside is the back main door is usually smaller then the inside dimensions, so you will have remove wings and prop and oil tank. Never attempt to fly a 400 pound Kolb home if you are unfamiliar with it's handling characteristics. Good Luck -------- Both optimists and pessimists contribute to our society.

Wes Wes/Kolbers: This is the Kolb Aircraft Builders and Flyers List. We are much more interested in building and flying Kolbs than other brands. Kolbs have all the other brands beat hands down. There is no comparison between a MKIII and an S-12. The S-12 is not nearly as crash worthy as the Kolb, a very, very important characteristic. I've been told by some that they are not concerned about crash worthiness because they are not going to crash. Wish I knew that. Since I don't, I'll stick with a good crash worthy Kolb. I've never flown an S-12. Don't know if they fold or not. I do know the S-12 fuselage doesn't hold a candle to the Kolb. I have also seen several S-12 that crashed. They do not do well.

Wes -- I have owned both an S-12XL (about 2 years) and a Kolb MkIIIC (7 years)... I currently own the Kolb. The Kolb is sturdier in most every way, plus the wings fold easily, quickly and can be done alone. My opinion only, of course, but I thought the S12XL actually flew a tiny bit better, was a tiny bit more fun, and I thoroughly enjoyed flying it, but the wings don't fold at all... they basically just have to be removed, which is a major operation, starting with draining the wing tanks... overall, it's doable, but generally speaking, you're talking several hours/half-a-day ~at best~ to remove, and then another several hours to put back together. If wing folding is anywhere in your top 20 characteristics, then it's no contest. You'd have to go with the Kolb. Despite my slight preference for the S12XL for flight characteristics, the differences are very small, and I very much enjoy flying the Kolb. And, without a doubt, if I could choose which one to crash in, then it's again no contest... the S12XL will roll up in a little ball, and you with it. I've seen it happen to others but, luckily, I've never experienced it. If I had a hangar with room, I'd have both. But I needed a plane with foldable wings, so the Kolb was the best option, IMO. -- Robert On Mon, Jan 28, 2013 at 7:20 PM, alienwes wrote: > > Maybe I can get the forum talking with this question: Has anyone compared > the Kolb Mark III and the Rans S-12? > > Does the Rans S-12 fold as easily? > > Has anyone flown both and how do they compare? > > Wes > > -------- > Wesley Elliott > Sport Pilot-PPC > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=393208#393208 > > ________________________________________________________________________________

I have flown both. Only my opinion but I would go with the Kolb. One fine day flying a S12, 2 up off a sealed runway, at the end of the runway the 12 was at 500ft agl swapping to the Kolb we were at 1100ft at the same point. Both were 503 powered and at sea level . I would consider the S12 very under powered with a 503 and the Kolb acceptable with a 503 . I also prefer the third wheel to be at the back, I find the ground handling of the Kolb to be much better . In fairness I have flown the Kolb a lot more and would only have about 1 hr. in the S12 and over 200 in the Kolb. Out of the 9 or so aircraft types in my log book the only ones that come close to the Kolb would be the Piper cub or Aronca champ. A couple of the others were high performance so can not be fairly compared .

Rick Neilsen If the mechanic was making money off the Manatee Ultralights, he'd have a change of attitude. GA types like the 172 owner/pilot are a dime a dozen. They have this "my airplane is bigger and more expensive than your airplane complex". Most of the GA pilots at our local airport, 08A, never fly, and if they do, it is around the patch. Airplanes don't make the pilot either. Most of my flying friends are retired military or professional civilian pilots that like to fly Kolbs and other small experimentals and ULs more than they do GA aircraft that aren't nearly as much fun to fly. john h mkIII Titus, Alabama ________________________________________________________________________________

Kolbers, I'm making this post on behalf of fellow Kolb owner & pilot Dean Chandler. He asked me to let the list know he is moving from Kentucky to Florida and has his Kolb Slingshot for sale. He would have made the post himself, but lives so far out in the boonies he does not have internet access. I first saw his plane back in 2007 at the Kolb Factory reunion. At the time I knew nothing about Kolbs or flying for that matter, but we stayed in touch and I have a few photos of his Slingshot on file which I am attaching. He told me the 582 engine has over 500 hrs, well past TBO, but according to him it still runs fine and has flown within the month. He is asking $6500 for the plane. It is N359RC and has an A/W certificate dated 1999. When I last saw it, his Slingshot was one fine looking Kolb. Dean's ph# is 606.305.7870. If anyone is interested, he asks that you give him a call.

Guys Need this plane like I need the other three that I have...but...a deal is a deal!!...so...going up Sunday morning for pre buy inspection..I have dibs till then... I told Dean to call if someone calls and wants to head that way before hand with cash in pocket...therefore giving me first refusal... the 582 has 500 hours but fly's strong... If I buy it and very likely I will, I may want to replace the engine...though I have no qualms about flying a high time 582... :-) I understand that the wings will not fold if a 912 is mounted...? How about the HKS as an option....naturally I would look for a used one in either case ...:-) Do not envision using the rear seat....Herb Kolbers, I'm making this post on behalf of fellow Kolb owner & pilot Dean Chandler. He asked me to let the list know he is moving from Kentucky to Florida and has his Kolb Slingshot for sale. He would have made the post himself, but lives so far out in the boonies he does not have internet access. I first saw his plane back in 2007 at the Kolb Factory reunion. At the time I knew nothing about Kolbs or flying for that matter, but we stayed in touch and I have a few photos of his Slingshot on file which I am attaching. He told me the 582 engine has over 500 hrs, well past TBO, but according to him it still runs fine and has flown within the month. He is asking $6500 for the plane. It is N359RC and has an A/W certificate dated 1999. When I last saw it, his Slingshot was one fine looking Kolb. Dean's ph# is 606.305.7870. If anyone is interested, he asks that you give him a call.

Herb, The N-number (registration number) means it is an aircraft, not a UL. Slingshots (and all other Kolb models) meet the limitations for LSA. Therefore, the pilot must have at least a Sport Pilot certificate, a valid and current US drivers license (or current FAA 3rd class or better medical certificate), and a current flight review (in last 24 months. Lacking any of these, a pilot cannot fly it legally. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 no engine FOR SALE Diamond Katana DA20-A1 Rotax 912 F3 Don't worry about old age... it doesn't last very long. - Anonymous Read this topic online here: http://forums.matronics.com/viewtopic.php?p=393445#393445 ________________________________________________________________________________

Herb, There's a lot of if's here so you'll need to take this with a grain of salt. You say the plane is a 98ish build. IF the plane was registered at that time it will almost certainly be as an Experimental Amateur Built. In that case you will need to have an A & P do an annual on it AND sign off any engine work you do. You cannot get a repairman's ticket for E-AB unless you are the original builder and you requested it at the time the airworthiness inspection was done. On the other hand, IF the plane was used under one of the old alphabet UL groups and operated under the two place training exemption and THEN grandfathered in under the Experimental Light Sport program (FAR 21.191 i (1)) then you can take the 16 hour class and get a repairman inspection card (LSARI) for it and do the annual and engine work yourself and sign it off. Without that ticket you will have to take it to an A & P OR someone with a repairman maintenance card (LSARM) to do the annual and supervise your engine work IF you want to keep the logs up to date and maintain the value of the airplane. As Thom said, no matter how the plane is registered, E-AB or E-LSA you're going to have to get at least a Sport Pilot airplane ticket to legally fly it.

Anyone can work on an E-AB, and charge money for it, for that matter. What they cannot do is write anything in the engine or aircraft log books, anything of a legal nature anyway. The last caveat about maintaining the value of the aircraft is what having an A & P supervise the engine over haul was meant to convey, so no, no requirement unless you want a logbook entry to go with the work.

Thom, I should mention that it also depends on which version of the Operating Limits go with the airworthiness certificate. In the latest version there would be a requirement to notify the local FSDO of a major overhaul so they could put it back into Phase One testing and prescribe a flight test area. See Order 8130-2G starting on page 4-64, "(19) After incorporating a major change as described in 14 CFR =A7 21.93, the aircraft owner is required to reestablish compliance with 14 CFR =A7 91.319(b) and notify the geographically responsible FSDO of the location of the proposed test area. The aircraft owner must obtain concurrence from the FSDO as to the suitability of the proposed test area. If the major change includes installing a different type of engine (reciprocating to turbine) or a change of a fixed-pitch from or to a controllable propeller, the aircraft owner must fill out a revised FAA Form 8130-6 to update the aircraft=92s file in the FAA Aircraft Registration Branch. All operations must be conducted under day VFR conditions in a sparsely populated area. The aircraft must remain in flight test for a minimum of 5 hours. The FSDO may require additional time (more than 5 hours) depending on the extent of the modification. Persons nonessential to the flight must not be carried. The aircraft owner must make a detailed aircraft logbook and maintenance records entry describing the change before the test flight. Following satisfactory completion of the required number of flight hours in the flight test area, the pilot must certify in the records that the aircraft has been shown to comply with 14 CFR =A7 91.319(b)."

Herb, your best bet would be to use the Slingshot to fly off your hours. Of course you will have to be solo'ed in it first. You will have to find a instructor that will check you out in the plane. When I was trying to get my privates lic. I bought a EAB Mark III, with the thought of using it to fly off my hours. I did manage to get the instructor in the plane for one ride, but he would not ever get in it again. Of course the thought of being only surrounded by fabric, rather than tin foil was too much for his limited mind to grasp. That should not be a problem with a LSA instructor. Just make sure that the plane has a current annual. If the engine is flying well, keep it in the pattern (or not) and work on the engine after all the dust clears. Hang in there, it took me 10.6 years to get legal, and force myself to jump through all the hoops. Its all good though and worth the effort.

From: Larry Cottrell <lcottrell1020(at)gmail.com>
The cold grip of winter here in the West has finally loosed. Today the temps soared to a dizzying 61 degrees, with no wind even. It was just too much for a mere mortal to resist. I rolled the Firestar out of the hanger for the first time since Oct, The runway was firm enough to use without damaging it with the tail wheel, so there was nothing to stop me. Every thing checked out and the sky was waiting. My landings were actually pretty good for a change. I did about 12 touch and go's before I decided that if the engine was going to quit, it should have already done so. I left the field and flew over to the ranch next door looking for Coyotes. I only forgot one thing- my chewing gum. I apparently habitually fly with my mouth hanging open and after an hour and half, I finally had to land to get rid of the terminal dry mouth. Hope that good weather comes to a location near you soon.

The only requirement on logbook maintenance entries is within the last 12 months there must be a condition inspection signed by either the original builder with a repairman's certificate for that aircraft or an A&P (no IA needed). Of course, if the work constitutes a "major alteration" it should be logged by whoever did the work along with the FSDO testing requirements and completion of those requirements.

The FAA came out and inspected and assigned a new test area to fly off 10 hours. This was done last spring it's been flying ever since.

thought I might reply on line to a couple of questions. Firstly; with the 582 at normal cruise, forget the rpm, around 70 mph, I would get somewhere about 5 gph burn and 6 gph at around 78 mph. More than that if I were packed for camping. Had to tape the rad at cooler temps. The 912 gets me a solid 3 gph burn up to about 4700 rpm, around 75 mph. I now push it harder at 5200 rpm and 95 mph and get around 4 gph burn. In rough air 90s are somewhat bumpy and touchy on the controls but got a tail wind coming back from Thomasville last year and was clocking 126 over the ground. That was nice, dry, cool and smooth. THAT is why I love the 912. I found out I was actually running it too slow. Supposed to run it up to the 5000s for best performance. Actually runs cooler now too. By the way, since Miss Lite changed the gears in my gear box, there is a lot less noise and at the higher rpm, it is quieter and smoother also. Just thought I would throw that in. Have a great day.

That bearing failed in the 582 aircraft engines and failed in the 580 Sea Doo, The 583 did not have the problem because there so fast you can run them wide open for a long time. Rotax put a bigger bearing in the 95 aircraft modle, (and that is still the cause of every 2 out 3 582 engine failures) The aftermark guys double slotted the Sea Doo rods to get more oil to the bearing and that worked. Thats why I say all 582,618's and 670 engines need 40 to 1 oil ratio. Those bearings will fail sooner or latter without it. Here is what I do that makes the 670 work now, In the 98 /99 year high output models ( 132 HP ) they increased the top and bottom eye's and used the same size crank pin & wrist pin, they filled the gap with much larger roller bearings . These are the rods we now use since Jan 2010 and we use double slotted rods to get more oil to the bearing. > Call me for more help & info . I will tell you what to do if you want to build your own.

Subject: That old bugaboo, liability
From: Richard Girard <aslsa.rng(at)gmail.com>
I am fortunate to live in an aviation community. A 2500' grass runway abuts my back yard. For this and the five acres that allows me to feed wild birds and enjoy nature (even the coyotes except when they take one of my guineas or chickens) I am very grateful. So you can probably understand I am not at all happy when some idiot uses our runway in a completely stupid manner. I am also the home owner association president so I have the interests and property values or my neighbors in mind, too. We carry a $1M liability policy for which all of us pay an assessment each year, but with the damage caused by Katrina, Sandy, et al, the possibility of loosing that policy or having the premium raised to a level that is not reasonable should someone make a claim against it, has caused me more than one sleepless night since two incidents happened in the last year. One, where a new property owner was allowing his and his friends children to play on the runway while the friend was trying to teach himself to fly ( I couldn't make this stuff up, cross my heart, it happened) and two, where same owner brings his "instructor and mechanic" to fly the plane. He proceeds to ignore the pattern direction arrows and FAR 91.119 and fly at tree top level over the homes and hangars of many of the members of our HOA until the engine seized and he was barely able to make a crash landing going ACROSS the runway. When questioned by a couple of the members the "instructor" refused to either identify himself or account for his actions. He was actually surly about it until it was explained that he could tone down his attitude or he could talk with a county sherrif deputy. In those sleepless nights I pondered what amendments to the HOA bylaws would allow us to weed out the idiots and whatever other measures we could use to protect ourselves. This last Thursday an article on the ANN "Propwash" newsletter told of the legislature of the State of Arkansas had just past an amendment to their recreational land use act to specifically include aviation. I was immediately interested and went looking on the web for information about similar statutes in Kansas. I found this site. http://theraf.org/sites/default/files/raf_files_videos/recreational_use_statutes_50_state_discussion.pdf Seeing that Kansas statute is of the "including, but not limited to the following" listing of recreational activities I contacted both my legislators to ask that the statutes be amended to specifically include aviation in that list. "Dear Sirs, I request that language be added to Kansas State Statute K.S.A. 58-3201 to 58-3207 to exempt private airports from liability when such airports are open to the general public as defined in the legislation. Small, privately owned airports receive no public funding yet they are a vital resource to Kansas. In times of disaster emergencies or environmental accidents such airports may be the only link for relief, medical care, and evacuation. As such I believe that they should be entitled to specific relief from liability. I would appreciate any effort you are able to give to make this change to our state's Recreational Land Use Act." To my surprise and delight, both my representative and senator responded with a personal note, not just a form letter of the "thank you for contacting me" genre, promising to look into it and address the issue when the legislature returns to session. On Friday I brought the issue to the attention of my EAA chapter and got some more information from other members who live in airport communities. My plans at this point are to A) use my list of chapter newsletter editors to spread the news and ask for more effort from across the state to get the statute amended and B) put up a Facebook page to solicit support and spread the news nationwide (only 16 states specifically mention aviation or aviation sports in the RLUA's) Guys, I urge you all to look up the link and see if your state is one of the 16 or one of the 34. If your state is in the latter group, write to your representatives and get the ball rolling. Okay, Russ, I've given us something that, while it isn't specifically Kolb related, it certainly directly affects Kolb owners and flyers. Hey, it's winter and I'm flying the trike right now (3 flights in January and 1 in February so far) while I plan the repairs of Zulu Delta.

Hi everyone, Sorry in advance if you do not like the topic, but I am sure others who decided to buy/build a Kolb looked into GA aircraft before making the decision. I have a local Dr. who is selling his Cessna 152 for 14K. He says operating costs are around the $42/hour range. It just had a rebuild 28 hours ago. I am pricing Mark III's and most are in the 20K-30K with a 912. I see some immediate benefits of both. Kolb needs no hangar fees, only a trailer. Kolb can take regular gas Kolb has better performance/climb Kolb has no medical requirement, but I can easily get a medical at age 33 Kolb has less annual costs Cessna is cheaper to start with AV gas is higher Annuals are higher Needs hangar Flies faster/farther Anything I am missing here? What are others operating cost per hour?

The Cessna could be moderately useful for travel, even for 2 (small) people. But probably a lot less fun than the Kolb. You can purchase an auto fuel STC for it, assuming you can find alcohol free mogas in your area. But it will almost certainly burn more of it. Medicals have gotten expensive where I live, even if you have no trouble passing them. You don't really *need* a hangar for a Cessna; it just keeps it in better shape. Annuals can be really cheap if nothing's wrong & the IA will let you do all the work, but if he isn't accommodating, they can be really expensive. Also, there's the ever present threat of AD's. Any time the ownership of a particular product on the plane (carb, mags, engine parts, Anything) changes hands, there will be an $AD$ on that product. Count on it. A friend purchased an old 150 that had been out of annual for several years. He paid something like 8-9 thousand for the plane, with a ferry permit to get it home. The 1st annual (before he could fly it again) included rebuilding a twisted wing & cost more than the plane. Only anecdotal, but it's not that unusual with older planes. How familiar are you with the history of each plane?

You can do all the maintenance on a Kolb yourself; you only need an A&P for the annual. The Cessna needs an A&P signoff for all maintenance other than a short list of simple preventative maintenance. A Kolb will eventually need a fabric recover job, the Cessna won't. At 14K the Cessna sounds like a great deal if it's in good shape. With a Kolb you're part of a great community, both Kolb guys and the larger experimental community. With a Cessna... well... it's just a Cessna... But most important: the Kolb will be a lot more FUN! -Dana At 09:52 PM 2/17/2013, alienwes wrote: > >Hi everyone, > >Sorry in advance if you do not like the topic, but I am sure others who >decided to buy/build a Kolb looked into GA aircraft before making the >decision.

Wes, I was in the same boat, Wanted another Kolb bad but also wanted a 4 cycle. Could not afford anything with a 912, Jabiru or HKS. Ended up buying a nice Ercoupe, love the plane but repairs and annuals are difficult and expensive. And no short field capabilities. My next plane will be Experimental.

Alien , I have to question the cost of operating a 150 for 'about $42/hour'. Really don't see how it can be that low, esp. if he carefully includes everything. Like adding a buck or two towards the eventual overhaul. And does he include the cost of his own physicals? I had a 170 for 20 years and kept careful records. Just can't see that 42/hour unless he flies 300-400 hrs a year. But congrats to him if he can fly that cheaply.

Ultralights are few and far between in the Ft Lauderdale area, as we as even just open ultralight-type experimentals. Id say the best bet is to venture north up to lantana or F45, or south into some of the outer airports in Miami. I know at lantana there are a couple challenger experimentals, but not much... I also think there was a guy giving rides out between Labelle / Clewiston...around the hang glider activity. Maybe give them a call to see what is possible. http://www.thefloridaridge.com/pages/pilot.php Good luck!

Thanks everyone for your insight. To answer the question on my pilots license, I already have my Sport Pilot, but need a fixed wing endorsement as its only for PPC right now. That reduces the cost for the Kolb. I am assuming this Dr. just threw out a number for operating costs for the Cessna that he was told. Do not think he really considered all the facts. I do like being part of a community, which the Kolb seems to have much more than the Cessna. Just like the community of PPC pilots I enjoy knowing.

One of the advantages of fan cooled engines is that the cylinder temps stay more uniform. A free air engine cools down a lot more than a fan cooled engine while at low throttle on approach. When you throttle down a fan cooled engine, the fan slows down and the airflow across the cylinders decreases, so the engine stays warmer longer. This is particularly important if you are doing touch and go type flying. Cold seizures can occur when you got to full throttle after a long approach. The aluminum piston heats up faster than the steel cylinder, expands, and smears itself all over the cylinder walls. So even if you could get the CHT to be within spec at full throttle, there is still a good reason to stick with fan cooling. -------- There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.

Wouldn't it be a good idea to block the air flow across the cylinders on descent? Some sort of venetian blind type of contraption? Also , rather than taping the radiator...a venetian blind mechanism with 0 to 100% blockage on the radiator of the 582 and 618 seems appropriate..

After two cold seizures, I tried to build something like that for my free air 277, but the vibration from that little beast kept tearing apart whatever design I came up with. I finally solved the problem by having the cylinder honed out about 0.003 larger than factory spec and running a main jet 2 steps richer than spec. I'm also very careful not to go to full throttle immediately after a long descent at idle. On a touch and go, I'll usually take off with about 3/4 throttle and wait until the CHT gets up to 250 before going to full throttle. -------- There is something fascinating about science.
