I’d say set them at 100 before calibrating. After you are done, set to 120. Not many people do that, and I didn’t want to complicate it for non-racers.

If you are only going in reverse, you will have to switch the throttle to either reverse mode, or make sure the motor leads are hooked up correctly. For a Futaba (or other transmitter with adjustments) you can switch throttle to reverse mode. On a Traxxxa transmitter, you can switch the inputs on those too, but you'll have to find the instructions for that transmitter.

@@BloodlineRC I figured it out it was the transmitter itself not binding to receiver

No. That is not normal. I’ve had that happen before. First I make sure my transmitter throttle EPA is set at 100. The throttle trim is centered, then I will try another calibration. If this is a completely new esc or receiver combo, you might need to either take the throttle in or out of Reverse settings on the transmitter as well.

@@BloodlineRC I’ve tried everything. About to give up.

@@rustypope1778 maybe try binding the reciever onto a new model first. Then recalibrate? That way you have a new model and the 3PV settings are at the default.

@@BloodlineRC ch2 trim 0 Ch2 sub trim 0 EPA B 100 F 100 EXP B 0 F 0 Calibrated esc to radio Took 42 clicks of throttle trim for it to engage. Something just noticed, I tried reversing Ch2 and with all trims still 0 the motor is engaging with no action of trigger

@@rustypope1778 I’d try resetting the trim, while it’s reversed and re-calibrating the esc. Then see where you are
