ok just did a run with 14 cells and took some temp readings.

ESC - 32C (90F)
Motor - 72C (161F)
Batteries - 86C (186F)

Now the batteries are getting pretty hot but i really like the speed of it :) I'm thinking gearing up to and 18T pinion will probably cool it down a bit. would going to a 17T be enough of a change to drop the temp but without too much speed compromise?

Also im interested in why the esc temp is pretty much the same between the 2? My expectation would be that the added voltage of 14 cells would increase current draw and make the esc run hotter? Am i wrong in thinking this?

I've been running on grass thats about medium length, about 2 - 3 inches
