Hi
I have an 8ight who i have instaled a Xcelorin system to, somthimes when i hit full throttle it's cuts of, and if i lett the throttel go and hits it again it dosen't happend, this only happens when the car is standing still and hit full throttel, is this right? I'm running whit the 1700 combo en 5s.
Or is this an adjustment to the esc i need to do?
