I'm finding the car runs lovely now, until it gets a short distance away from me, and then it either starts twitching itself or wont respond to controls. I have to walk closer until it responds.
I've tried moving the receiver a little which did improve the distance, but I'm really restricted as to where I put it as there's no room left on the chassis.
I'm running a 27mhz AM setup.
Can anyone shed any light on this problem? could it be interference?

Really Interesting...
I have the exact same problem on *2 cars* and ....
I have in common:
# 27MHz AM
# quite powerful BL motors (4.5t on ZX5, 5.5t on B4)
# Distance from TX is critical to these glitching issues
I don't overgear (I think...17t in ZX5, 21t in B4). Also, I have tried a data logger on the car: the voltage is not always low when glitching occurs. .
Until now, I've been blaming the TX because... I re-cycle some Kyosho perfex mini-Z TX that I thought could be low in TX power(designed for indoor).
I am about to compare my min-Z TX 27MHz AM with my proper(?) 40MHz AM sanwa radio. It will be monday when I get to the lab at work.
I will keep you posted on my findings and the possible solutions I find
