I have two F type A units, both powered that I would like to run together. The only thing is the both run nose first so I was thinking this, Since they are both DC, can I reverse the wiring on one of the motors to make it run in reverse while the other runs forward. I am first test them one behind the other ,uncoupled, to make sure they operate at near or at the same speed. First one engine ahead of the other then switch their positions. What do you think?
