hey guys, took my plane for a fly a week ago and had 2 perfect flights, then this morning took it out for a fly take off perfect, pulled the throttle back to 1 quarter stick, and PCM kicked in, it locked into a bank and i almost lost the plane, scared the crap out of me

..
any ways i pulled the throttle after about 15 seconds of no responce from the plane, and landed it, Now i have worked it down to be ignition interference... what have i done wrong, i range check the model without motor running and i get heaps and heaps of range, i turn the motor on, at full power range is not reduced but at a little above idle power setting, the reciver locks up, and goes into PCM, and controls are real laggy and they just stop, then respond like 3 seconds later [:@].. What do i do, i think its because i have the throttle and choke servos 1 cm away from the ignition switch? is this causing interference to go into the throttle and choke servo leads from the ignition switch, and it is feedbacking into the reciver? Should i Take the switch out and mount it on the opposite side of the fuse or somthin? What to do...
