If this happens once the car is started It may be from vibration. unplug and re-seat all your plugs going to your receiver including the battery plug.

Pass you soon...

The plastic spring loaded battery holder in your car is possibly the problem. There are crimped connections in the holder that dont always make good contact. Especially when vibrated by the engine. The radio you have is not great but I would not blame it for your problem. A flat 5 or hump pack will fit in the NTC3. Ditch those AA's!!

Futaba has a 2.4ghz radio thats only $200 TX/RX. You allready have servos.

My M8 fm radio likes to glitch when I adjust mixture or put the body on. No big deal usually, works fine on the track.

Once it was really bad and thats because the antennae was pulled of the board. I soldered it back on and its been good ever since.
