I have a APO-DL 2 channel motor controller. I triple checked the connections and they are exactly like another one that has been working for a year. I am not using an Arduino, so this should be an easier diagnosis. On the first hook up, the motor worked fine, then was stopping at intervals. I adjusted my axle to stop the binding and it worked a bit then the motor would stop again. I am assuming that I have a bad motor controller and ordered another one. The motor starts when connected directly to the battery, but doesnt when connected to motor controller on either channel.
All the other servos work on the transmitter and receiver, just the motor doesnt.
I don't know this APO-DL driver, but in many cheap drivers there is noticeable voltage drop on output. You could measure that with voltage meter. Maybe output voltage is too low for your motor. Maybe battery is unable to provide enough current for your motor while passing through your driver and wiring.
If you want more than guesses here, you should post all necessary information about your setup, motor, battery , wiring etc.

The motor is a 24V 150W Scooter motor. The battery is a 14.8V lipo. I have it in a tricycle and have used the same setup in my other build. Same parts and same board. Motor didnt need to be fully powered to get the desired speed out of it since it will be slow moving.
Chucky has been working for over a year with the same setup. I verified that everything was connected in the same manner and checked all connections. The only thing I havent checked is how to determine if the board is bad somehow.
ALWAYS use substitution to debug physical projects!
I finally bought a multimeter and tested the board. I didnt have any output from either channel, so I guess I blew up the board when a wire came loose. Oh well. Problem solved.
