Is there possibly a bad cell or solder joint? I had problems with my 9920 because of a questionable solder joint, and then because of bad batteries.

My 9920/7xl combo on my Supermaxx similar to yours, I would constantly overheat it seemed no matter what I did. I was running TP 6000mah GenIIs which I thought were nice batteries until I puffed one. Way better than my GP3000s.

Last week I just got new Poly RC 20C 5000mah 2s1p packs, and now everything runs super fast and fairly cool! 99f on the fets and 135 on the motor, batteries only got to 83f! This was after 20 minutes on the track, and after a recharge same temps doing speedruns/wheelies down the street.

I do run a fan on the esc, and the rc-monster heatsink on the motor. 14/51 with UE diffs and 40 series mashers.

I would think the 1930 would run even cooler than the 7XL because it's more efficient, I want to try a 1950 for that reason.

Good luck getting it worked out...$$$$ --> at least it's priceless when everything's running right, so much fun!!
