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

Here is an update on the TX comparison:
(1)My 1988 Sanwa Dash 40MHz AM
(2)My 2002 Kyosho Perfex KT-5 (mini-Z) 27MHz AM
(1) is far more powerful TX (+10dB more on the antenna!) than (2)
(1) has much better performance at 30feet (-25dBm vs -55dBm !) than (2)
seems like modern radio regulation/legislation has forced radios to become anaemic
This may explain some of my issues. I need more testing...
Let us know if a 2.4GHz solves your issues, I am very interested
