Okay, so I've got the Aeroworks .46-.60 sized Edge 540T. I put an OS .61FX in it, a Futaba 6EXA, broke it in with a 12x6 prop and recently switched to an 11x7.

As of this morning I had about 4 flights on it and it was a very well-mannered plane. This afternoon, I took it out, gassed it up and took off. Flew the pattern for four or five laps to make sure it was still trimmed out etc...

I finally worked up the nerve to switch on the high rates, rolled inverted and yanked it through an outside loop. This is where things went south... After the loop, it decided it wanted to roll hard left. I tried to correct it, but it did it again. Switched it back to low rates and it still did it. About this time I have every R/C pilot's worst nightmare, an out of control plane headed for the pits. I cut the throttle and pointed it at the ground. Bent the crap out of the landing gear, but better it than some person.

After I bent the landing gear back, I checked the plane over for anything obvious that might be causing this. It's balanced fine, no loose covering that I could find, range tested it again and it passed, no slop in the control surfaces, nothing loose anywhere that I could find, no metal that could vibrate together to cause radio interference, stabilizers didn't come loose and are still straight. In short, it appeared that nothing was wrong.

I decided to put it back in the air to see if it did it again, thinking that maybe I just took a radio hit. I took off and it rolled hard left. Got it trimmed out so that it would fly straight and level again at about 1/2 throttle. I had to trim it way too much to get it to stay straight. And now, if I speed up, either with the throttle or in a dive, it still tries to roll left. If I stay around 1/2 - 2/3 throttle, it behaves.

Any suggestions?[sm=confused.gif]
