esc settings are,mode1 is set to the race which is 2 blinks, mode2 is set at 3 blinks, mode3 is 0 blinks, mode4 is 0 blinks. radio is a old M8 settings on it are throttle epa high100% brake epa 100%, the speed control trim is centerd.thats what the instrution say but what about the expo adj. should it stay at 0 or 100% I didnt think that should matter because it's just to change the feel of throttle, how fast it comes in could be wrong.
