Im having problems with my new set up? Its a C & N 5000w 72v rear hub motor kit from China? I'm using the supplied controller and tft colour display and an upgraded Domino throttle. Problem is when i crank the throttle really hard the throttle symbol on the display lights up orange and cuts the power? If i throttle up gently and smoothly it doesn't seem to be a problem? Quite a bit of delay in throttle as well, i reckon i have about 10mm of play before throttle kicks in? I haven't tried the cheap Chinese throttle that came as part of the kit? Cheers Lads Gary..
