Hello @jeffM, while the winning remote has a very good form factor, it is known to be unreliable. Unreliable in this case means it doesn’t have a great range and is prone for interference. That’s not good. However what is worse is that the fail safe function is very often not set properly. So when it looses connection the receiver holds a random throttle position.
You need to calibrate 0 throttle position for a better fail safe, see below. And you should test it on the bench by applying throttle and then walking away with the remote or switching it off.
And if you adjust throttle position via the small screw, you need to re.calibrate again.
Here the steps for binding and calibrating fail safe (throttle at 0 position)
Check and make sure all the wires are connected and that the REMOTE is OFF. Insert the bind plug into CH3(Bind) on the RECEIVER.
With the REMOTE OFF: switch on the ESC to power up the RECEIVER, the red LED light will flash.
PRESS and HOLD the bind button on the REMOTE and then turn the REMOTE ON.
You should notice the REMOTE and RECEIVER LED light go from flashing red to solid red.
Once you see a solid red light, the binding process is complete. Then without turning the REMOTE OFF or touching the THROTTLE pull the bind plug out (for the receiver to record the throttle mid point, neutral, to engage the fail safe)
Then you can test it again by turning OFF the REMOTE and the RECEIVER LED should flash. By turning the REMOTE ON the RECEIVER LED should go back to solid red.
Before riding, it’s better to test the fail safe functionality again. Leave the board powered on and switch the REMOTE off: if the motor isn’t moving, the fail safe function is working, if the motor is moving fast or abruptly braking while throttle is applied: you have to repeat step No.1- No.6
