Wondering if anyone can assist me, I have a g4rs with futaba 9451 servos and a spectrum reciever. It appears that the vibration of the car vibrates the sectrum reciever and causes the spectrum to go into fail safe. I have replaced the battery (in case) and the spectrum reciever but i haven t been able to stop it. I have temporarly mounted the reciever on the top deck and got the same problem (The light on the reciever goes off and i loose remote). If the motor is not ruunning or i have the reciever loose above the top deck the problem goes away.. I am not using a switch as i also eliminated that. I have also dissconected both servos from the reciever and with the reciever mounted i still loose remote.
Thanks

if every thing is disconnected and engine not running and looses signal, then id say it is a comunication problem with the radio. try a fresh model number (one not setup for a car) rebind reciever, then recharge the battery. if your using a new TM pack, it may need a couple of charge discharge cycles. but it would be best to make your own pack, or switch to lipo. see if you can hook up a voltmeter to the battery while its turned on, se whats happening wiht the voltages. if nothing is plugged in, then the current draw should be minimal, and the voltage should be stable. once the servos are plugged in, stall them one at a time for a short burst, see what the voltage is dropping to. 2 digital servos will be quite a draw on the battery. some have used a capacitor from Spektrum, plugged into the Aux channel. stores some voltage in reserve when it needs it. also make sure there is no part of the wire for RX touching the carbon. if need be drill a bigger hole, and put some fuel tubing inplace and glue it. then feed the aerial through the tubing to the aerial tube.
if all else fails, try a friends transmitter and see if you have the same problem.
