Default Glitching - receiver close to motor

Tamiya TRF501x - LRP TC ESC - LRP 6.5 motor - OLD HiTec DC FM Receiver

I set the car up with the ESC directly behind the servo and the receiver directly in FRONT of the motor. NO DICE, horrible glitching.

Spent about 30 minutes diagnosing and have concluded that the receiver can't be anywhere near the motor (that may be common knowledge, never had to worry about it with stock truck racing). If I put the receiver close to the motor I get HORRIBLE GLITCHING, like full throttle blips and servo going crazy, kind of scary with a 4wd mod actually.

So WTF can I do? The ESC won't fit anywhere else without exposing the wire terminals to the outer edge of the car where they will surly take some decent impacts as they would literally hang OVER the edge of the chassis. Not to mention the leads for the power capacitor are virtually nonexistant (about 1/4").

Is this a problem with ALL receivers? Can ANY receiver be next to a brushless motor? What is the solution here people? Help, please....

Well, after tearing the car apart and putting it back together I'm still not 100% happy with how you have to lay it out.

Tamiya has photos posted that show the ESC with the leads facing the inside of the car... which is BS because they would get worn rather quickly with the nut from the spur gear shaft.

I'm totally frustrated as there is no proper way to set this car up that I can tell.

AWESOME car, just not meant to be setup brushless. FWIW, it works amazingly well, I just hope I don't get T-Boned and destroy a $200 ESC.
