Servo Twitch

I'm using the AR7000 and DX7. Does anyone know why my servos twitch every 10 - 15 sec. If so, how do I fix it? Thanks

Could be radio interference (damaged Rx wire or Rx) or wire interference... every charged wire lets off an electric pulse as a magnetic field. Make sure no wires are crossing the ESC wires and that the Rx wire is not damaged. Range test it before flight so you don't hurt your plane in flight.

The servos are Electrifly Nano's. I don't have any wires crossing the ESC etc. Are there any issues with Electrifly Nano servos?
Thanks for the ideas.

I had a plane with those servos and I think they suck. They never centered right and seemed very slow. However, your issue sounds like a power problem - like maybe the ESC isn't giving clean power. Try plugging a receiver battery into the system and see if it runs better - that's a 4-cell NiCad pack directly into the receiver. To eliminate the radio as the source, disconnect the motor or remove the prop, and apply power to the plane with the radio off.
