What is the RX? Wrap it in foil and make sure the antenna is not running by the motor/ESC.

Both Andy and Fred have good suggestions. The foil wrapped receiver worked for me several times.

On my two Promax 4014 Cobalt applications, one uses a GWS R4-P receiver with the ESC 6" away from the motor. The other application is a Zagi where the ESC is very close to the motor but I use a Hitec 555 recevier.

No problems with either setup.
