Right got the results from the 15t pinion today but couldn't let the LiPo finish as I had broken a lower arm running in to a post.
After 3 minutes:
Motor - 41*c
Battery - 26.5*c
ESC - 32*c
After 6 minutes:
Motor - 56.5*c
Battery - 29*c
Esc - 39*c
After 10 minutes:
Motor - 73*c
Battery - 36*c
Esc - 48*c
After 12 minutes:
Motor - 73*c
Battery - 37.5*c
ESC - 51.6*c
As you can see it's still disappointing and the motor is too hot to touch even after 12 minutes. I really don't know what to do now, shall I just get a different motor? Perhaps something around 2200kv and see how it goes? There's not much of a change from the 16t and 15t pinions but in fact the 16t pinion ran the electronics slighty cooler if anything.
Thoughts?
