Control from cheap esc not to bad very sensitive when turning, full speed quite low as only running 12v but axe control via 30 amp elecrtonize (not sure on spelling) seems to be fine.

ebay esc do cut in and out on heavy imnpacts looking to remedy this by removing all small connectors inside and direct solder if not just replace with my 2x10 sabertooth should be ok at 12v with drill motors
