i have a 1/8th scale hbx vrx-2 buggy. have been having servo interference for some while now. the car is off. i turn the transmitter and the receiver on. and there is hardly any signal being picked up, the steering is locked in right position and the steerinf doesnt respond to the transmitter. but when i use the throttle the steering picks up a little signal and wobbles but the throttle hardly works.

can anyone help me?

thanks
