ok I am having some weird glitching problems. my car will just randomly go full brakes. my setup is a jr z-1 radio, spectrum module, soektrum micro receiver, savox 1251mg servo, orion r10 pro, reedy mach 2 6.5. I am already running a racers edge capacitor. it seems when I put the antenna from the receiver further away from the motor it does it a lot less. could it being too close to the motor affect it?

any help is appreciated.
