Ok, I'm about to pull the rest of my hair out over this esc. When I got it, the throttle would go to like 25% after 20 seconds and it didn't have any brakes. After a month of waiting, Novak sent me a board to put in it. Throttle works fine now but I still have no brakes. I calibrated the throttle and still nothing. Also, the reverse does not work. It says it is turned on, but does not go into reverse. Any suggestions would be greatly appreciated. If I have to call Novak again I'll probably have to send it in this time and it will be another month knowing my luck.
