RX8 1700 truggy issues

[nuz69]

And geared for the same speed, The mamba 2200kV ran a little cooler or hotter than the tekin motor ?
Yes, the play in diffs is very bad, because the shimming is no constant, it eats your diff pinions and it drag the transmission + noise :(
175 °F is ok for the motor, but it is the limit, it means that you dont run it at its max efficiency (efficiency drops a lot with high temps...). You could increase significantly you runtime with a little lower pinion because lower amp draw and longer runtime ==> lower temp ==> best efficiency ==> lower amp draw ect...
Of course it wont give you an additional 10 mins, but it helps !
