Radio glitching!

[ralphee]

Guy i need some advice. Just installed a Hobbywing XErun combo in the TRF 511, and using a KO prop 40mhz system. Im getting interference/ glitching like a mare.
As i hit the throttle, the servo twitches to the left, this seems intensified on the track too!
Ive just don't a re install of all the wiring etc, tried a back up receiver, and crystals, still i get the glitch....any clues? No wiring is close to the receiver at all, was wondering about a glitch buster cap?
Failing that, do some brushless just not like 40mhz? Its almost like a spike as i hit throttle, or pass through the neutral to brake.
Need a fix as its my buddy Lozza using the car and i really want to sort it for him for this Friday!
