Ok I have a HPI Scream and Rage ESC in my XO-Demon TQI 4ch w/tel
And I cannot get the radio and esc to mesh, the neutral will not work all the time, thus no reverse.
Ive reset the esc and the radio, and still no hope.
It goes forward good, except at low throttle where it jerks forward.
Ok got it working better, reset the ESC - still not perfect, but have forward, brake, and reverse.
you probably need a glitch buster.
i am no expert with that esc or the XO-1 but that is my opinion
Take it all apart, where does this screw go again.
