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

You are overgeared too.
The same Orion esc in my B4 caused me problems last weekend at the Southport GP. I though it was interference because the radio seemed to keep cutting out, but knew it wasn't cos I was on 2.4gHz. Turned out I was massively overgeared and the power drain was knocking out the radio.
Massively over geared in this case was a 26t pinion, 81 (stock) spur and a 7.5. I've now dropped to 22t and the problem has gone. If I'm running 22 with a 7.5t 21 with a 5.5t must be too high. Go down to 18 or 19 and see what happens.
And a 5.5t is pretty mental in a B4 anyway.......
