brushless 1/5 4wd conversion about to begin! couple questions.

I think you hit the sweet spot because all your temps are well in check.

I would if dropping to the 12t would be too much reduction tho...

ok so i just tried the 12t pinion and ran moderately for 15 minutes. it is now 85* outside. motor was 110* esc was 130* and one battery was 91* and the other 100*. i didnt like the performance of the 12t as much as the 15t. the motor temps definitely jumped and it seemed the esc was a little cooler. everything just ran hotter now though cuz ambient temp is up and i pushed it a bit harder. i am still worried about that esc though. i know when i get in hills and actually run it hard it would probably hit 175* real quick. next i need to test with the fans on and body on etc. RTR.

what is the danger zone on this hydra esc? i would like to never see it over 150-160* but ideally i want my motor and esc to be in the 120-130* range. also, should i be concerned that one pack was 10* hotter than the other? is that saying something?


i talked with kulangflow from the forum today. he is the HD video master and if weather permits we have scheduled a to film this thursday. i wont have breaks by then so we will find a wide open area hopefully so we can open it up...perhaps a golf course??? hehehe

oh, can anyone tell me how else i could get my esc temps lower aside from gearing? i dont have any other gearing options. 40t spur is the largest i can go. i have been looking at a different Neu motor. i am probably going to buy the Neu 2220 2y 550kv. my current motor is 750kv. i know this would make the motor cooler but what about the esc? or would going up to 12s instead of 10s make any difference? i would get a much lower kv motor if i go 12s though. anyway, what else could drive esc temps down?
