Just though I would add my gearing and temps to the review for others to see.

Outside temperature= 55*
Motor= never over 110*
Neu 4s batteries= never over 75*
MMM= not sure, but the fan never turned on.
Gearing in E-Revo= 19p 56spur

That was in shorter runs lasting no more then 15 min at a time on the road since it was raining off and on today. Power seemed great! A lot of torque on demand. I can't wait to get a run in with dry weather... someday.

Tomorrow, weather permitting, I am going to try 19p 54spur and see if there is much of a difference in speed.
