Feigao heat problems.

ok, so if i get a 2000kv medusa geared 11/46 it will be. 46mph this is alttile fast for me. and to go with a lower diff ratio i would be spending close to $150, the air temps here are about 86*F, I live in Canada.
if i get the 1600kv motor it will be geared under 40mph, about 36mph with 11/46 gearing.
I dont drive Wide open all the time, i barely even get up to full throtle.
here it is with the medusa 1600
