The only "problem" I had was piling it in, completely destroying it, and severely damaging my NEW Taurus T-52 in the process. I do this series of outside, reversing, knife-edge snaps on a horizontal line...one way, then the other....looks pretty cool...On Extra flight number 13 (yes, I won't count them ANYMORE), on the exit line following the last snap, pushed over, throttled back, and it began an unbelievable roll DURING the radius. At the moment I pushed from horizontal to vertical, SOMETHING went "pop", and the incredible roll started. I had throttle, elev, rudder, trying ailerons to no avail.

Fortunately, it only had to go about 75 or 80 feet vertical before the impact, but...the line/snaps was probably half throttle, then throttle back, push down...kinda a square corner....then BOOM.

It was pretty awful to walk up to.....

Yes, radio and ALL servos, gears, linkages FINE...receiver is now flying my newest pattern airplane perfectly...same switch harness. In fact, several of the servos are in it....not a problem whatsoever.

So the mystery continues.
