bro my wife and i had major problems with the novak esc.... even after receiving it back from the factory (warranty) it was a mess. it simply cannot handle an 8 pound vehicle. there was another really good thread where we all voiced our concerns.

novak two and ta man on the thread support novak products and in the other thread if you run a search they are a complete mess and finally admit that the esc is 100% crap.

what we did was order the 150amp esc from hobbyking that worked perfect with the novak sensored motor and we have had nothing but good luck ever since.

i would post this in the thread but those two will just flame my response...

hope this helps.... the esc is total crap!!! i have known 3 other people who live in my state that it has failed on!
