RE: The Weirdest Problem
from memory they are the same as the 35a ones, u need to hold the button down when turning it on to enter calibration mode.
might be worth downloading the manual....
but i think once u have it in calibration mode, then u go full throttle (a red and a green LED will light up) then press the button, then go to full reverse and push the button, then return to the throttle to the centre and press the button to complete the setup.
