Motor Wiring

There can be several reasons for the ESC cutting out at full stick position. Mtronic ESCs like many others go through a setup routine at switch on and need the receiver to be fully functional for the correct deadband position to be recognised.
The procedure is to switch on the transmitter and centre all the sticks and trims then switch on the ESC and press the small button on the ESC whilst the two leds (green/red) are flashing. move the transmitter stick to full ahead then back to the centre position when the red led will light and then continue to the full reverse position finally returning to centre when both leds should Illuminate signifying the ESC is programmed to your transmitter.
The ESC will remember the setting for all subsequent switch on operations unless you press the small button whilst the Red/green leds are flashing.
The problem is that modern 2.4Ghz receivers take a few seconds longer than the ESC to initialise so the mid point signal is not present when you press the button.
If you are using the ESC to provide power to the receiver the situation will continue to give you problems.
I have solved this by disconnecting the red lead from the ESC to the receiver and using a separate power source for the receiver. You can then set up the receiver before connecting the ESC and completing the setup procedure.
In theory the problem should now be solved and all future operations can use the ESC BEC circuit as the ESC will remember the previously set positions.
Sometimes the settings don't work if the TX throttle channel is set to rev as against fwd and changing these after ESC setup settings may require resetting the ESC.
If the motor still cuts out at full stick you need to reset using less than full throttle when setting the forward and reverse positions. I usually put tape across the tx stick to indicate where the motor cuts so I can set accordingly.
If your TX has end point adjustment you can correct this via the Tx.
I believe Mark is referring to a faulty batch of their 15 amp ESCs which shorted at the exit of the two motor wires.
