Default Glitchy servos on T-rex

Hi there,
Have noticed that servos on my T-Rex are very glitchy. I have a Futaba tx/servos with an FMA autopilot receiver/sensor. I have the ESC directly below the rx which is inside the airframe a few cm back from the motor. Could interference from the ESC be doing this?
Many thanks

I'd move the esc to the side frame and nix the copilot and see what happens, if that fixes reconnect the copilot and check again.

Agree with Barracuda--In addition the Ant & Radio should be at least 10 Cm from ESC & Motor. Does sound like interference.

Also be sure Metal head parts (ths SE) are tight (The top part of the head & the entire shaft. Any metal to metal rubbing will create static. And a BIG one--I had this problem-- Make sure that NO bare antenna wire touches the FRAME. It's conductive (The frame) and will destroy radio reception.

I had the same problem with my Trex. I tried everything, and then I brought a ParkBec 6Volts. Installed it and my glitchie servo problem went away. Heres the link www.dimensionengineering.com/ParkBEC.htm.
Good pricing about $25.00. I also have faster servos once I put in the ParkBec.
