I recently read an article in SA about a garishly painted Cub clone. The word "build" was used liberally however I was never able to determine what the owner actually built. I use the magazine to weigh down the very light structures on my free flight models to take out the warps. I've been a...
Gene Soucy flew a BD-4 into Flabob in the 70's with those wheel pants. He didn't care much for them. They were kind of odd looking on the ground with the doors open. I've thought about them often over the years and wondered why nobody had taken the time to develop them further. Soucy would be...
I would get in touch with the various resin manufacturers and ask for supplier samples. I have found most to be accomadating. Make sure you have a company name. Just make one up. Make it a good one though, it will follow you around. Also depending on where you live, many composite manufacturers...
I would not add anything to the resin. I would control the bleed with a barrier between the laminate and the bleeder cloth. Either teflon coated fabric or teflon film or both. With teflon film, cut SMALL slits, don't poke holes. Holes somtimes close under vacuum. Map and record how many and the...
Torque tubes. Mount the aileron to the tube, arrange bearings on the rear spar, devise a control system to twist the tube. Used quite successfully on the Stephens Acro and probably others.
Scott, is it beyond the realm of possibility that a bit of the airplane could be sacrificed to address your concern? A dissected trim tab or control surface might be revealing and useful to other owners. Destructive testing means just that, so it will be important that its well planned. There...
I recently did a distructive test on a rib I built in 1965 with Weldwood Plastic Resin just for the hell of it. It has sat in an uncontrolled indoor environment with no varnish or coating of any kind. Hi humidity and +100/0 degrees F. Granted, no fatigue, however the glue lines remained intact...
My 1977 Cessna 150 had sawn edges on sheet metal detail parts, some poorly drilled holes and some generally crappy workmanship. It did spend time as a trainer and I sold it with 4,500 hours TT. Never saw a crack in the primary structure.
I'm 73 and an in the middle of a Bearhawk scratch build. Been scratch building planes since I was 18. Don't care if I finish, I do it to stay mentally and physically fit. I'm 6' 175, dog walk two miles a day, lift some weights and build airplanes every day. For me it's a happy life. My wife will...
