...if you say so then thats what I will do........

I don't want to lose my warranty.

That's certainly not what I said.


I suggested you use the smallest pinion that gives you the performance you want and isn't too hard on the batteries/motor/ESC. You can test this by checking temps during your runs.

If you see temps above what is safe (120F or so), back down on the pinion.

Smaller pinion means less load on the motor, and cooler temps, and longer life.
