I tried a working reciever and crystal outa another plane on another channel EVEN! and still, it jumps. I am using 6V NimH with no regulators. It sounds like the problem that cant possibly exist, but I cant find it... I just dont know. I knows its not the ailerons, the wings arent even on the plane. The choke and throttle can be ruled out, standard servos, working out of another plane. I think its the 8611. If you hold it in a bind it jumps almost every 5 seconds, if you tkae it outa bind, it only does it every 10 or so. If you unplug it completely, only maybe every 15-30. I think its the pull pulls having a problem being 2 inchs from the servo extinsions, and the antenna. I think I will put it in the tail, that might be it???
