Yal were right...over geared lol (I figured so too). I went up to a 86 spur (too lazy to change the pinion lol) and noticed a dramatic decrease in temps.
Before on 17/83 gearing after 30 mins of hard bashing:
motor was 150-160
mm esc was 180 ish
Now on 17/86 gearing afer 30 mins of hard bashing:
motor was upper 120's and lower 130's
mm esc was upper 140's and lower 150's
Much better.
Thanks for the help.
