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

re .the 624 receiver problem. I also noticed that when I cycle the elevator and rudder sticks at the same time the receiver stops working.
Is there too much load on the receiver. The battery is a 2000 Mill. pack (nimh) I don't seem to have the problem when only 1 servo is operating. Would the new dual antenna receiver be better suited for dual servos?
Thanks, Dave

You may not have a receiver problem. Try a different battery pack. It may be that your battery pack and its wiring just cannot deliver the current needed when more than one servo is operating. If a battery pack cannot deliver the current, the voltage drops. If it drops enough, then the receiver will quit working due to low voltage. You'll need to check things very carefully.

Thanks Bax!! I tried a different pack when I got home from work. It was probably a voltage drop.
