I believe you. I have seen quite a few GTB's bite the dust for no reason.
Also seen the Havoc Pro Bite it after not being able to gear it low enough for it not to run hot in a slash. That was a 17.5 combo.
Stick to Tekin ESC or Speed passion/Hobby Wing. Even if the Novak's last, the are by far the slowest ESC on the track. Unless you spill out the $200 plus for the kinetic esc.
EDIT: Also have you ever noticed that the only other company that gets threads like this started about them, is Castle.
Novak and Castle seem to have some real problems......
