Curious 36120 problem

[Gustav]

Yeah i'm not using lvc or ubec to keep these out the picture,so that's ruled out.
The reason for the high 11:1 gearing was it seemed less noticeable yesterday on higher gearing. Tried 14.75:1 through to 11:1 today with same results regardless of gearing.

It can't be 42K limit since it does it on 16 cells too.It doesn't seem to be a radio glitch either as it reliably/repeatably does it at anything above 80% epa,and there's no other glitching to speak of.

Below 80% epa it runs smooth but above that it glitches at full throttle.

So i'm thinking maybe a timing issue,although it runs smooth and cool up to 80% throttle.I'm a bit stumped on this one.

Only other thing i can think is batteries or wiring issue (perhaps not enough amps available or a wiring/bad solder joint issue).Lipos are rated 66 amps continuous.

Can you hook up a 2P setup? To get the amp draw out of the picture.

Only got the one pair of packs at the moment so unfortunately not. It will do it on 16 cells too but only with the wheels off the ground,runs OK on 16 cells at full throttle even on a high gearing,it seems more like a certain motor rpm where it happens rather than current draw.

Could a bad solder joint cause this syptom in your opinion,i might re do the wiring tonight.
