I just installed a 624 receiver in my 4 star and when i wiggle the aileron stick quickly,the light on the receiver goes out,throttle goes to fail safe and there is no signal to the plane until I turn the switch off and then back on again.
I've tried doing the same thing (wiggling) to all of the other channels and the receiver works ok. The transmitter is a Tactic 650. Any ideas???
Thanks, Dave
