I know I could just gear it down and reduce the amps that the system will draw. What I don't get is why would the ESC overheat if I am below the specs of the unit?

The 115A I was drawing was peak, under hard acceleration in grass. The constant amp draw could not have bee more than 60 - 70A. The ESC is rated for 125A constant and 300 peak.

If the esc is rated for 125A constant, I shouldnt need to gear down for 115A peak. I should be well within the limits of the ESC. The only reason for gearing down make it easier for the motor to move the truck therfore reducing the amp draw. Am I misinterpreting the ESC rateing?

That frequency thing could be something, but then why wouldn't the ESC manufacturer say that in the specs? They are the ones who set the frequency in the ESC. Its not adjustable in the Quark as far as I know.

And yes there is plenty of airflow over the esc its monuted by itself away from the batts and motor. I could add a fan to the esc, I have it here and actually planned on doing it just for safety, I just haven't gotten around to it yet. But that still doesnt justify the thing overheating when I'm drawing current below the rating. Am I crazy?
