Channel mixing can direct the motion of 1 control stick on the transmitter into 2 motors, allowing driving and steering with a single control. Without this ability, you would have to control the wheels on the left and right side of the bot with two separate controls (called "tank steering"). Some drivers prefer tank steering, but on many radios it's much harder to activate a robot weapon when both hands are needed for driving.

Channel mixing can be done in the robot with a Dual ESC board that has that feature. When you want to drive a bot with independent ESCs using a single control, you will either need an inexpensive channel mixing device in the bot, or will need to program mixing in the transmitter.

Programming

Important: The cheapest transmitters have aircraft-specific mixing, or no mixing at all. Your transmitter must have at least TWO programmable mixes to change tank steering.

The following mix has been tested on the Spektrum DX5-Pro, FlySky Noble, and Futaba 3PJ.
