Strange glitchiness with sidewinder and MM with ccbec

[Sammus]

Any other ideas what this could be? I thought I'd cured it but apparently I havent. My setup:

Pic.

I recently moved the BEC from the alu plate at the front to over behind the motor, but it didnt make any difference.

The glitching is still there, and my only options are to have the throttle cable running past the motor (how it is now) Or along the battery. I can't decide which would be worse - I'm thinking the motor would generate more interference.

Could it possibly be from the Rx sitting on the Servo?

This is driving me nuts There's so many variables. I do suspect it is the BEC though because I was having the same problems in the rustler that disappeared after removing the BEC. I even get glitching without the wheels on, just sitting there blipping the throttle, very occasionally the throttle just locks on for a couple seconds. This has already caused my poor car a bunch of damage :(

Does anyone else run those glitch buster caps? I'm considering it, but it seems like a bit of a bandaid solution, I want it to run properly without one...not many people seem to use them...
