HV-Maxx motor thermal shutdown problem

Whilst waiting for the HV to be released, I did seriously think about getting a Feigao 9L/10L motor with a BK 9918 controller. That setup would undoubtedly have much more power, but I wanted to start with a lower-powered setup, that has a few advantages over the Feigao/BK setup in my opinion (sensored system, useable BEC, better warranty, motor heatsink & ESC fan as standard). Maybe I should have taken that route instead. If the HV motor gets this hot in mild Spring temperatures, it's surely going to be even more of a problem in the Summer... :M: [/B]

Well, I don't know about the better warranty statement. BK has been great so far in my dealings with them. The warrior and Feigao combos have been very reliable and would outperform your Novak without question. The Novak gets the edge in low speed operation, but I would rank the BK/Feigao systems higher in reliability and overall capability. Also, the BEC on the warrior controller is quite stout and can be used for up to 16 cells in most applications.
Your truck is on the heavy side, which is certainly part of the struggle with the Novak system and the thermalling. I would continue to gear down until it stops thermalling. A fan on the motor will help a bit as well.
