Just put the offset in opposing directions on each side so one hinge keeps its sister on the other side positioned horizontally.

Some metals will rub together without binding, such as bronze or brass against almost anything, steel against steel, or steel against aluminum. The process of that you described is generally known as gauling (if I spelled it rite). It generally happens with softer metals. Some metals are so bad that they can weld together, for example, lead. The aluminum should have either an AN washer between the two aluminum pieces, or pressed in bronze bushings. I used the half thickness AN washers between mine, AN mark number AN960-10L I think. If I were to do it again, I would use oilite or similar. - -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ------------------------------ Date: Mon, 27 Jul 1998 17:00:07 EDT From: KR2616TJ@aol.com Subject: Re: KR: parts giveaway (MAC trim servo) In a message dated 98-07-27 15:34:46 EDT, you write: << I have the model 4A, the one with the shortest travel.

There is a celebration of the 1893 Land Rush going on in Perry the same weekend as the Gathering, so there will be a carnival going on it town, complete with old west shootouts and a big party till the wee hours Saturday night/Sunday morning. The City Flyover is the KR Gathering contribution to the festivities, and will take place right after the parade through down town. Formation flying will be briefed for those with experience, and single ship flybys at the town center will follow. Should be a pretty good showcase for all those who fly in. This year's gathering promises to be alot of fun again, with the opportunity to enjoy some of the local history as well as the airplanes and people. I'll post more information as it becomes available. Again, the place to stay is the Best Western Cherokee Strip, (580) 336-2218.

Unless you weigh 330 lbs, you had one too many people in the airplane. You're right Rick, giving taxi rides probably isn't a good idea. Even though Oscar is a great pilot, a novice was at the controls. Things could have gone very badly. I felt pretty comfortable solo at 30kts. and kept it much slower going dual.

The key word in your cautions seems to be "high-speed" taxi tests. This did not happen, nor could it have happened due to the very safe and controlled manner in which the tests were done. A person could have walked or trotted alongside the plane most of the time. Paul had a fire extinguisher at the ready. An observer was present at all times, and the field was abandoned except for another pilot/onlooker with his leashed Rottweiler. Paul intentionally carried only a minor amount of fuel in the tank, due to continuing system flushing; at no time could the aircraft have ever gotten light under the mains, because the man "knows his limitations" and held to them. Several good things resulted from the tests: Paul is now aware of how light the nose can be at high angles of attack with two aboard and near-zero fuel, and can compensate for that. He was also able to try several canopy positions to get cooling air into the cabin while taxiing, yet still had an observer to watch the rwy while messing with it. These comments are not meant to make light of tests, only to clarify that Paul is not a loose cannon. He is an EAA member and local chapter volunteer in many functions, seeks and uses the advice of others, and is prudent. Heck, he even has a 'chute to use on his 40 hour fly-off period. Thanks for the safety reminders. I turn 47 today, and plan to hang around a few more because flying makes it fun. No death wish here! PS- Thanks for the Columbia pix, Mark.

If the mains are located 4 inches aft of the main spar then I am willing to bet it was loaded aft of the aft limit. Using the mains to get an idea of the CG location is from my C-207 days. If it (C-207) plopped on its tail while loaded but came back down on the nose wheel when I climbed in then the CG was OK. If not you could expect some wild pitch oscillations at cruise. zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290,..

It is beginning to shape up nicely. I am using some 1" styrofoam insulation sanded get the rough shape and then build up coats of Plaster of Paris on top of the foam. I am glad I thought about wrapping the engine with plastic because some of the plaster will run through. I hope to be able to continue the curve of the fuselage on to the cowling on the sides without having to build bulging cheeks. It looks like it will work out so far. I am taking pictures of my progress and will post them when I get the roll developed. (Sure wish I had a digital camera).

You can use 3/8" spacers for the starter but the generator is an inch longer than the pull starter. The key starter is shorter but there is a problem with the sprage clutch. So that leaves only the B&C starter ( $800 ) that will fit that mount. Also I have run into numerous problems trying to get a cowl to fit the stock O-200 that you would be seen in public with.One in the dumpster and a better one in work. I may know where there is an O-200 GPU. I'll check this out and get back with youguys later ( I think about $1200 will buy it F.O.B. Tulsa,OK. Next, does anyone know where I can find O-200 Mag. gears P/N 36066 ?? I need two and the drive gear assembly for the generator.

Put the washer on before it galls, or sand it down first. You're probably going to have to sand it anyway, to make room.

Although you've probably seen it, there's a great design in the November 1992 (copyrighted!) KR Newsletter for a dual stick setup which rotates about the axis of the aileron cable when moving fore and aft to operate the elevator. End of problem, except it's a dual stick and somewhat complicated (involves welding 4130 steel). But I think I decided after seeing it to use it (although I could design a single stick version) because this allows me to fly with either hand (or thighs) and relocate my flap handle to between pilot and passenger. This would give me more room 95% of the time (solo). Time to order 4130 tubing, I guess. Maybe somebody will draw this up (paraphrased, of course) and throw it out into the public domain soon...
