You are right, takeoff is no problem at any weight. Landing is no problem either as long as you are experienced in short field procedures and don't get excessive speed on final. There were a couple of times I did a go-around because I let the speed get too high and then floated down the runway. In my 4 I calculated that 70mph was a good short field speed for me based on what MY stall speed was. Yours may be different.

Thankfully, there were few interesting findings. The aircraft now has 221 hours. It has a 180hp A1A with Lasar ignition and Performance Airflow fuel injection. The prop is a CS Hartzell. The airframe presented no problems save for the rudder which now has small cracks on 3 of the forward rivets on 3 skin stiffeners on the starboard side. My rudder has an 0.016 skin and has RTV in the trailing edge per Van's original recommendation. I have stop-drilled the cracks and have started a new rudder with an 0.020 skin. On these stiffeners, I will use ProSeal in addition to rivets. Both the fuel injection system and the electronic ignition continue to perform flawlessly. I can't tell that I save any fuel or gain any power with the Lasar system - I'm just happy to have everything working. Again, I found a severly cracked plate that mounts the airbox to the air induction/fuel metering system. This same part was found cracked and replaced at last year's annual. My current hypothesis is that the lower cowl pre-loads the airbox via the rubber snout at the air intake. I have cut away a small portion of the snout in an attempt to relieve the preload without sacraficing seal quality. Clearly, I will have to keep an eye on this. I also noticed I have lost a single eyelet on one of the hinge strips on the cowl. At this point, I will simply keep an eye on the eyelets, as I don't have a good long-term strategy. The tires still have another year of tread remaining. I have 2 years on these Aero Trainers and will end up with 3 years if they make it to the next annual. The brake pads are still the orginal set. Some wear is evident, but still well above the minimum thickness requirement. I usually land on long, paved runways, so the brakes don't get much hard use. I have 3 years on the orginal Concorde gel cell and see no reason to replace it. For the first time, I had a compression test done on the engine. I don't have tools and have never done one, so I had the field FBO do this for me. The lowest cylinder was 76psi. All told, this annual cost me 6 quarts of oil, one oil filter, and an airbox mouting plate. Plus about 3 days of my labor with my Dad's help. The rudder cost, however, has yet to tallied.

I'm guessing at the number, as I haven't actually measured it yet. I find this when, on pre-flight, I grap both trailing edges, and pull one up while pushing the other down. Has anyone else noticed this "problem"? I'm not sure what could cause this other than a slight (very slight) elongation of the hole in the control horns. Perhaps there is a better way to tie the 2 horns together than just the single bolt from the push/pull tube bearing.

Why is it important to have a seal between the snout of the airbox and the cowling intake hole? I had a rubber seal there when I purchased my RV-4. Because of vibration, it tore away and the close fitting snout gauged away some of the glass around the intake opening. I cut back the snout about 1/4 inch. I never replaced the seal. I have seen no problem, but that does not meant that there IS no problem. I have an IO-360 with C/S prop. Am I missing something? Thanks.

I have zero play and this is something I always check during preflight. I agree that play here is a very bad thing and must be fixed ASAP.

Do a little more research on your own, and I think you'll avoid it. Basically, it's too good to be true for most of us. A good friend of mine owns one of these machines. They've been around awhile now, and his sits in the corner of a room with it's pretty white cover on it. Basic eye-anotomy: We have 3 parts: The length of the eye from the front of the cornea to the retina, the cornea (front clear membrane in front of the iris), and the variable powered lens just behind the iris. The length of the eye and shape of the cornea are fixed, and change little with the years. The lens is an incredible piece of work: Controlled by a muscle, it thickens in it's longitudinal shape and increases it's curvature when the ciliary muscles contract. These muscles are not the extra-ocular muscles that help our eyes to point correctly; these are inside the eye and only act to change the shape of the lens when focusing on your charts or focusing on the spam-can you just passed. Every year from age 6 and on, the lens hardens and loses flexibilty. As it does, you lose your variable focus system. IF you have no Rx (perfect 20/20+ distance acuity), then you lose the ability to see up close. First the phone book, then the charts get tough, vision worsens in low light and you start ordering the "special" at restaurants instead of getting out your readers, and eventually everything within zero to 5 feet is difficult to see (especially the meal on your plate). At the same time the lens is hardening, from about age 30, it also starts turning yellow and becoming hazy. Depending on how fast this progresses, you could end up losing best-corrected acuity anytime after age 40. This is called a cataract. Wahoo! I say all this, because when you look at the procedure, it changes the shape of the cornea. The cornea is fine. It's not the problem. The only way to get good far and near focus back is to take the lens out of the eye and replace it with one that is flexible again. They're working on it. We may be 5-10-15 years out yet, but bifocal implants are coming. Too many of us need them now! At the same time, it's not a muscular problem either, so you can't "exercise" it back into submission. If you scan down that webpage I referred to, there is a little paragraph that says they are using the procedure to make one eye nearsighted and leave the other one farsighted. Hmm. I've seen this work about 1/3 of the time with those who wear contacts. I don't know that that's what I'd want to have while landing on a short grass strip 45 minutes after sunset in drizzly weather.... For "Black" and others, Do Not Archive - this has nothing to do with building an airplane, only seeing where we're going.

I had to clear trees on the approach end so I used full flaps and then ended up picking up a little airspeed when getting down just past the trees but with johnson bar flaps you can drop them the minute the wheels touch to increase stall speed and it helps to make sure you stay put. Easily landed with 1000' of runway left in front. Point here again is good short field landing technique. Tim Bryan RV-6 N616TB Flying This Year! -------Original Message------- From: rv-list@matronics.com Subject: Re: RV-List: grass runway length for RV's? --> RV-List message posted by: "Jaye and Scott Jackson" Years ago, I practiced spot landing with maximum effort stops on a grass runway prior to going into a one-way, 1700' strip with tall trees at one end and a fruit orchard on the approach end, plus it was uphill( a plus) with the wind above the trees occasionally a tailwind for departure( not a plus). The first time I actually landed on the strip I had been practicing for, in a 180 hp, fixed-pitch wooden prop RV-4, two-up( owner in the back), it sure looked short while we were on final, but the slope contributed to that appearance. We actually aimed for the treetops on the approach end as the lift of the wings will keep our flight path slightly above that, and practically drove the machine right onto the ground with only a slight flare to preclude a bounce.A wheel landing was used to eliminate float, followed by raising the tail to kill the lift while coming on the brakes moderately until an overrun was not in the cards, and we used less than half the runway. This was at sea level, on a summer day, which on the Pacific Coast means around 20C. Add a little lift from the extra bouyancy of both of us holding our breaths during the latter stages of teh approach and landing..... The departure was equally impressive due to the performance of these machines, and that's without a constant-speed prop. Taxi up against the tall trees, swing the tail almost into the trunks, full power, minimum-drag attitude for acceleration, hold it level after liftoff for a little extra airspeed when encountering that slight tailwind at the treetop level and there's plenty of room left. Which is a long way of saying that you should be fine within the parameters you describe. Walk off the distance on a longer runway, then perhaps practice to see how it feels and performs for you before committing yourself.

I had LASIK surgery done ...... without the monovision (one eye near, the other far) and although really happy with the outcome, there are some down-sides. 3 years after surgery, street lights in the distance have crude star patterns to them, but get sharper the closer they get. When I look at the full moon I see a 'upside down mickey mouse head' with the face being the bright moon and the 'ears' as darker 'false moons'. Don't know how to say it any other way. I'm 20/20 in one eye and 20/35 in the other now. Anyway, I still have to use reading glasses (2.5 cheapies from Sams) and I had my prescription sun glasses made with bifocals focused a little further out for the instrument panel. I still carry the clear reading glasses though. Helps me read the menu when we fly for food! There is newer technology for 'mapping' the eye for LASIK that uses wave-front technology .... which is supposed to be more accurate that the procedure that I had.

My youthful perfect vision suddenly went south during USAF pilot training in the mid sixties. For many years, say from age 22 to age 45, it gradually got worse. Then maybe 10 years ago the ophthalmologist at my HMO said it was time for cataract surgery and they would replace the natural lens in my eyes with new plastic ones, and the plastic lenses would correct my vision too. They did one eye, then a few months later did the other one. The next time I took the test for my driver's license, they removed the corrective lens restriction on my license. On my last flight physical, they removed the corrective lens requirement for flying - the first time since 1966. My vision without glasses is not perfect. Even though I legally don't have to, I still wear glasses for driving and flying, and most of the time for everything else. But I don't have to. One of my eyes is now slightly far sighted; the other slightly near sighted. I can read just fine without glasses, but better with them. Same for most everything else. For those with normal but aging vision, the answer may be bifocals, or trifocals, or what I have been wearing since long before my eyes were surgically corrected, varifocal lenses, where the correction gradually changes without abrupt steps or lines. And they can put them in those studly fighter-pilot frames just like your sun glasses. Or little round wire rims if that's how you see yourself. Terry --> RV-List message posted by: BBreckenridge@att.net I say all this, because when you look at the procedure, it changes the shape of the cornea. The cornea is fine. It's not the problem. The only way to get good far and near focus back is to take the lens out of the eye and replace it with one that is flexible again. They're working on it. We may be 5-10-15 years out yet, but bifocal implants are coming. Too many of us need them now! At the same time, it's not a muscular problem either, so you can't "exercise" it back into submission. If you scan down that webpage I referred to, there is a little paragraph that says they are using the procedure to make one eye nearsighted and leave the other one farsighted. Hmm. I've seen this work about 1/3 of the time with those who wear contacts. I don't know that that's what I'd want to have while landing on a short grass strip 45 minutes after sunset in drizzly weather....

I have had readers and found I needed them more and more. They were rarely at hand when I needed them. I found even driving or flying I could see just fine until I needed to see the sectional or map. I ordered a pair of bi-focals with just glass on top. It took me a while to get used to these but now I wear them most all the time. Still don't like wearing glasses, but being able to read everything I touch again is priceless. I am pretty used to them now and wear them all day.

Due to the hardening of the lense, you can have either uncorrected good near vision or good far vision, but not both. I'm 55 and have had Lasik and ended up with the situation you mention: one eye better than the other. I had the option of going back to further correct the weaker eye (the better one is 20/15 and the weaker about 20/25) but I discovered that the brain will take over and compensate; I don't even notice the difference most of the time, and it's never been a problem even on misty, rainy nights, and is certainly not a problem under better conditions. It took about a month to adapt. The reason I didn't go for the enhancement of the weaker eye is that it also works in reverse: I can still read without correction in good light, and can easily see the instrument panel in any light without wearing correction. If both eyes were 20/15, I'd have to wear reading glasses to see the instruments. I can't imagine any problems as long as your vision with both eyes together is good. -------------- Original message -------------- > --> RV-List message posted by: BBreckenridge@att.net > > Dave; > > After brousing around a little, I found a fairly straight-forward site that > covers the aspects of CK (conductive keratoplasty) and the expected outcomes > (http://www.emedicine.com/oph/topic736.htm).

The lens is an incredible piece of work: Controlled by a muscle, it thickens in it's longitudinal shape and increases it's curvature when the ciliary muscles contract. These muscles are not the extra-ocular muscles that help our eyes to point correctly; these are inside the eye and only act to change the shape of the lens when focusing on your charts or focusing on the spam-can you just passed. Every year from age 6 and on, the lens hardens and loses flexibilty. As it does, you lose your variable focus system. IF you have no Rx (perfect 20/20+ distance acuity), then you lose the ability to see up close. First the phone book, then the charts get tough, vision worsens in low light and you start ordering the "special" at restaurants instead of getting out your readers, and eventually everything within zero to 5 feet is difficult to see (especially the meal on your plate). At the same time the lens is hardening, from about age 30, it also starts turning yellow and becoming hazy. Depending on how fast this progresses, you could end up losing best-corrected acuity anytime after age 40. This is called a cataract. Wahoo! I say all this, because when you look at the procedure, it changes the shape of the cornea. The cornea is fine. It's not the problem. The only way to get good far and near focus back is to take the lens out of the eye and replace it with one that is flexible again. They're working on it. We may be 5-10-15 years out yet, but bifocal implants are coming. Too many of us need them now! At the same time, it's not a muscular problem either, so you can't "exercise" it back into submission. If you scan down that webpage I referred to, there is a little paragraph that says they are using the procedure to make one eye nearsighted and leave the other one farsighted. Hmm. I've seen this work about 1/3 of the time with those who wear contacts. I don't know that that's what I'd want to have while landing on a short grass strip 45 minutes after sunset in drizzly weather....

Not tested, just surmising here........ (((((((()))))) [Larry] You are surmising correctly. You want the lower cowling area to be a low pressure area, sucking or freely accepting air from higher pressure of the plenum area or upper cowling as it cools the cylinders. Allowing air to flow into the lower cowling area from the FAB air intake opening would be counter productive in a couple of ways. Lower manifold pressure for the carb and less cooling. > > Brian and the original poster who experienced cracking: How much clearance > did y'all have between your airbox and inlet? (((((())))) [Larry] One of the things I noticed on my 7 is the engine mount and the engine is offset to the left while the cowling is not. This causes a tight fit along the left side near the FAB at the bottom. Is it possible the FAB is rubbing or contacting the cowling which puts pressure on the plate causing the cracks? There should be some sign of this on the inside lower cowling if it is happening. > > From The PossumWorks in TN > Mark -6A ((((((((())))))))))) Indiana Larry, RV7 TipUp "SunSeeker" The sincerest satisfactions in life come in doing and not dodging duty; in meeting and solving problems, in facing facts, in being a dependable person. - Richard L.

That said it was able to correctly place me in 46 of the 48 states this summer, and was never more than 120ft off course. At most times it was within 60 ft of course. The Navaid would never be this close, and in fact is ususally .25 miles or more off course. The EZ-pilot will make use of turn anticipation data if your GPS supports this as does a GNS430. This allows for one to set up a 160deg turn to final approach and have the plane come out of the turn within one tick on the Localizer. The unit will display much of your GPS data such as waypoints, ETE, GS etc. Then you can display more screen or other data on the GPS. I often use the EZ-pilot to display ETE to way point when close then go to the GPS screen and set up the next "direct to" but leave it on that screen until within 1/4 mile, then engage the next leg. With RVs having a multi leg plan is a waste of setup time usually. The only time I've found them usful is when making a precanned approach such as RIPON > FISK > RWY36. The LCD TC display is much easier to see in the sunlight then the LED of the Navaid, or the VFD of the earlier EZ-Pilot.

The first person to be sued and try to recover $ under one of those provisions is going to likely have to fight for it in court and then those companies will quickly reword their policies to specifically exclude that coverage. I'd recommend that you have an annual done on the plane as the pre-buy. That way you have an independant person stating that the plane was airworthy at the time of sale. You're always going to be 'on the hook' as the assembler of the plane, but if you didn't stray from the plans there is little liability there. If you modified a bunch of things (or anything) there is some liability you've assumed as the engineer/manufacturer of that part. JT ----- Original Message ----- From: ed To: rv-list@matronics.com Sent: Sunday, August 29, 2004 9:19 PM Subject: RV-List: Liability when you sell an RV? --> RV-List message posted by: "ed " So one of the reasons they say that homebuilt planes are so much cheaper is that the builder is on the hook instead of vans for liability reasons. So I assume that means if you sell your plane, that anyone who ever touches it after you can sue you if they are in an accident? Has a homebuilder ever actually been sued in a situation like this? Any thoughts on how to protect yourself? I imagine having the buyer sign something saying he understands it is a homebuilt wouldn't help. If nothing else he could sell it to a 3rd party who never signed such paperwork. Given all the insurance related talk recently I was wondering if this is something that people are thinking about. --Eddie http://toolbar.msn.click-url.com/go/onm00200415ave/direct/01/ ________________________________ Message 43 ____________________________________ Time: 03:20:26 PM PST US From: Mickey Coggins Subject: RV-List: Vortex generators --> RV-List message posted by: Mickey Coggins >I put vortex generators on the wings and it really made a difference.

Stall went down maybe 2 mph, cruise went down 5-6 mph. It gave a quicker roll feel - almost "twitchy" but you got used to it and kind of liked it after awhile. I took them off after a few hours cause they hurt cruise more than they helped stall. I heard Larry Vettermans VGs are a lot better (I think they are bigger and mount further forward on the wing) I'll try his if a few people verify that theory.

The following was posted by Jim Oke many years ago - it worked great for me (I used some 0.040 steel sheet I picked up at a scrap yard - aluminum will probably wear from the drilling, and will eventually get too sloppy): ================= I made my own template out of a scrap of .040 or so 4130 (could have been 2024, of course). Draw an X with the legs at 90 degs, then two concentric circles at 1 5/16" and 1 3/4". Drill #40 where all the lines cross - nine holes in total. (The Aircraft Spruce and Spec catalog has a diagram if you need more layout info.) Lay out your panel marking where the center of each instrument face will lie. Drill #40 at these locations. Cleco the template in place at the center hole, make sure everything is square, then drill the four holes at the small or large circle as needed. Then set you fly cutter as reqd and cut the instrument cut-out using the center hole as a guide. Do a few test holes in scrap first to make sure your layout is accurate before you start on your actual panel. :-) ================= And the following great tip was posted by Dennis Persyk. Of course I forgot about it, so I never tried it. I just stumbled across it again when I searched my treasure trove of saved RV-List gems. ================= I recommend a fly cutter and 200 rpm or so in the drill press. Use lots of clamps. It is very hard to get the fly cutter radius adjusted just right. Once you have it at the right radius (determined on many scrap trials), make a cut 1/2 way through some 0.062 stock. When you need to cut another hole that size, use the half-cut template to adjust the radius. This will get you repeatable hole diameters to within a few thousandths. ================= Just use some care when laying out the template, and you'll do just fine. -- Kevin Horton RV-8 (finishing kit) Ottawa, Canada http://go.phpwebhosting.com/~khorton/rv8/ ________________________________ Message 49 ____________________________________ Time: 06:17:03 PM PST US From: "Jim Thorne" Subject: Re: RV-List: knock it off --> RV-List message posted by: "Jim Thorne" Do not archive Tom, how anybody could not see your humor is beyond me.

I lost count, but it was 8 or 10 of 'em... Anyway, I noticed two odd things about my oil temperature gauge (and with 275 hours on the plane, I'm sure I'd have noticed before now.) 1) With the strobes on (hazy day) the oil temperature gauge immediately read 10-15 degrees higher than with the strobes off. Turning the strobes off returned the temp gauge to where it was before... 2) Whether the strobes were on or off, the needle on the oil temp gauge had a little wiggle in it. Kind of like the shakes I get when I've had a little too much Diet Coke. The gauge and sender are the Rochester brand, as sold by Aircraft Spruce. My immediate thoughts are to check the connections on the temperature sender and gauge. Any suggestions beyond that?

The change in reading is caused by the increased current draw of the strobes making the voltage drop. The wavering needle is a sign of poor voltage regulation. This can be caused by the regulator itself or by lousy rectification in the alternator. Blown diodes in the rectifier also show up as a whine in the radio .... and the frequency changes with engine RPM. The ripple on the oputput of an alternator with blown diodes will cause an electronic regulator more problems than the old relay style regulators. Of course all this may be way off the mark but it's my best guess with the little info you gave. Congrats on the YE flights.

Dean, I am sure I speak for RV builders worldwide who express our appreciation to you for getting all the out of tolerance parts out of circulation so the rest of us won't have to deal with them...... ;-) > > > Latest BS has to do with mounting the nose wheel tire..I split the rims and > installed the tube in the tire and tried to put the rim halves together but > NO WAY.

Does anyone else make this size tire? Thanks. Just go ahead of bolt the two rim halves together making sure you haven't pinched the tube. Once the bolts are torqued, add 40-60 lbs of air to the tire and the bead will pop into place. Then reduce the air pressure to working pressure. Don't really see where anything could be out of tolerance. I believe the wheels are made by Cleveland, and there probably isn't much variation in the tires. Getting a grip on tire changing is mostly a matter of figuring out some technique; if you are grunting, you ain't doing it right. ;-) Sam Buchanan (lots and lots of practice flippin' tires on the RV-6) ________________________________ Message 55 ____________________________________ Time: 08:34:08 PM PST US From: Jerry Springer Subject: Re: RV-List: More kit frustration!! --> RV-List message posted by: Jerry Springer Dean Psiropoulos wrote: >--> RV-List message posted by: "Dean Psiropoulos" > >You know I love the RV airplanes and I've been privileged to know Dick VanG >for many years (a fine gentleman whom I greatly admire).

You have to do a little bit of work, Also use a little bit of soapy water if they are to tight. BTW it is not Van's fault if the tires or rims are out of tolerence. Did you try both wheels? Did you let all of the air out of the tubes? It takes a little effort to get the wheel halves close enough together to get the nuts started on the bolts. The tires well not go all of the way onto the rim untill you start putting air into the tire.

I got my vortex generators from Larry Vetterman 605-745-5932 and installed them with the templates and cement furnished. I painted them to match the areas of paint in which they were installed. They are aluminum and curved to match the wing contour. Cost at that time was $400.00. Instructions were very good and installation didn't take very long. I'll post a picture in the matronics photo section. Hope this helps Bob Olds RV-4 , N1191X A&P , EAA Tech.

He left out a few items though. Use a lot of talc on the inside of the tire, on the tube, and on the rim. Rub it in good. Put the tube in the tire. Remove the valve stem. Use a blow gun to force some air into the tube and then let it excape. Do this a few times. Assemble the rims on the tire. You may have to squeeze the rims together with a large clamp to get the nuts started on the bolts. Carefully tighten all 3 bolts. Put the valve stem back in and inflate like Sam advised. Don't skip the talc. It'll keep the tube from folding over and creasing ..... which will be a leak if the tire loses pressure down the road. It also allows the tire/tube to shift a little during use. If you want to replace your tubes each time you replace the tire .... go ahead. Properly assembled with the talc you can get 6 or 7 tires for each tube. At least I do. I've never had a problem (yet) with old tubes. The tubes in my Pitts are original. They're now 23 years old, and I may replace the tubes next time I change the tires.
