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

Most twin-stick transmitters have a menu option for 'Elevon' or 'Delta Wing' mixing. Turning on this option and plugging your left drive motor ESC into receiver channel CH1 (Aileron) and upir right motor ESC into CH2 (Elevator) give you basic forward/reverse throttle and left/right rotation control on your right-stick if using the US standard stick assignments.

Important: Some transmitters may have no mixing at all. If they have at least TWO programmable mixes it is possible to program your own mix:
