so it took me a bit to get everything wired up but just tested it RTR with the 12t pinion and i was totally surprised. i thought because i have the esc in that enclosed box that there was no way the temp would stay low. plus i have wires galore in there, my rx and my 2s battery mounted on top of the box all contributing to heat. i do have 2 fans mounted to the box. one on each side of the esc aluminum pipes for direct cooling. but only one of the fans was working. so i ran it anyway. after 5 minutes all the temps were the same: 85* for motor, batts, esc, and bec. i ran another 5 and motor was 95* batts 90* and esc 87*. i ran another 10 minutes and motor was 100*, batts 90* and esc 90*. after that i was pretty convinced that things are gonna work out. i am now gonna try the 15t and see how things hold up cuz i like the 15t performance much better. based on what happened last time i think its gonna work but i really think a 14t pinion would be the sweet spot. with the 15t i expect the motor temps to go down about 5* and esc to go up 10-15*. we'll see.
