outrunner'd e-revo

[kevin23]

I just got in from racing at the local track today,truck was faster lap time wise by almost 1 sec.The truck was pulling everybody out of the turns pretty good too,even the truggies.
I kept an eye on the temps,seem to be inline with what i got running it at the house,until the main.
at the end of the 10 min main motor was 180-190,esc was 120-130,and the batt's were 110-120.not sure if I should go down 1 or 2 teeth on the pinion,or if it could be running hot because it may be under geared?
any insight?
