Guys, thanks for all the great advice. I took it all in, and I've made some progress. To eliminate any fuel line/tank problems, I totally replaced the tank and fuel lines. I also added a fuel filter between the tank and high speed needle, and another fuel filter on the pressure line between the muffler and tank. (As per the advice of the hobby shop guy.) I also leaned it up a little bit. So I ran it up, gave it a couple minutes to warm up and then took off. The engine didn't die! But now I have a new problem. The airplane started a left bank, and I couldn't get rid of it. I put in full right aileron, and it helped a little, but the plane continued to slowly angle off to the left. So I cut the throttle and let her glide in to some tall weeds, escaping any damage. The plane even cart wheeled once since it had the left bank in slightly on impact. Anyway, the red flag here is this has happened once before when I was learning to solo, and the plane wrecked also. So since I've had so many engine problems, I forgot about the left bank problem. On the ground everything checks out. The rudder, elevator, and ailerons all swing in their proper respective directions. Range check works fine. No wind. Batteries fully charged. No loose servo horns. I'm out in the middle of no where, and nobody else is on the same channel. I can pretty much rule out someone else in the area on the same frequency. So as you can see, I've already thought about most of the obvious causes, except that I am on channel 52. I've heard 2 separate people tell me now that for some reason channel 52 has problems. Has anyone else heard this before? I'm using a Futaba 6EXA transmitter, FM Channel 52. Again any advice on this is much appreciated, and thanks in Advance! Mitch W.
