I have a HB Ve8 running a Tekin T8 1700kV/4S 14.4v battery / Rx8 BL ESC/ Spektrum SR300 Rec. and a DX3C radio. With everything hooked up , I found that everything is running in reverse.

Fast reverse speed (forward throttle)
Slow foward speed (rev. throttle)
Steering reversed.

Is this a radio issue or an ESC issue?
