"Well I never tried to run two ESC's off of one receiver channel, but if that is what you are wondering:
The ESC will send power to a brushless or brushed motor in a polarized direction. Meaning, when it sends a forward signal, the motor is driven in a direction. When reversed by the transmitter, the motor spins the opposite direction.
The specific direction of rotation depends on motor connections to the ESC. If forward signal from TX produces a rotation opposite of what you want, you swap the motor connections to produce the proper direction. Brushed motors you swap the two connections. Brushless motors you swap two of the three wires.
So, in theory, if you want one receiver/tx channel to run two ESC's to produce two different motor rotation directions, you can feed each ESC the same RX output, and change motor wires to produce proper direction on each motor.
Let me know how far off I was from what you wanted."
Boy did I read that wrong last night!!! Sorry for the misdirection.
