perfect loop
Hi guy's:
Still learning to fly on the buddy box. Yesterday,my instructor and I were going up for the second time, I took off, banked to the right, started gaining some altitude, when all of a sudden the trainer did a perfect loop. I thought my instructor had taken over, for some reason, because I knew I had not done that loop!
So, I asked him if he had done that, and he said no. The plane started doing all kinds of erratic stuff and neither one of us had any control. The plane was doing its own thing, waffling and floating thru the sky. Finally, my instructor gained enough control to get the plane down in one piece, he did a super job of saving that plane. We were lucky. The battery checked out fine, antenna wire was where it has always been, came home and did a very long range check, everything worked fine.
Any ideas,so this won't happen again? There was another flyer in the air at the time, but was on a different channel. Does it sound like I could have been hit by some one, somewhere?
Thanks in advance for your input.

RE: perfect loop
Check your wing. I had a plane do this to me (a trainer) and it turned out that the High G's I was pulling and the over sized engine I was running seperated the joint where the two wing halfes come together. This allowed the wing to flex/flap at higher speeds. At high speed the plane did a loop on it's own with no input from me. Kind of scary isn't it[X(]

RE: perfect loop
You could've had wing flap...not enough or/and reused rubber bands...lets the wing float around changing the incidence, and sliding side to side....do not reuse rubber bands they're just too cheap to risk your airplane over....I always use 12 rubber bands front to back and criss cross like this ( lXl ) do this 3 times....Dave has a excellent idea as well

RE: perfect loop
You might check that the buddy box cord and connectors are working properly. Especially if the buddy box has some age on it.
Ive seen two cases, several years ago, where the buddy box connector was the grimlin making an airplane do funny things.
As best I remember, the connection became intermittent and would basically cancell the control from either Tx.
Cheers.
