This RC mixer from RobotLogic is specifically designed to allow driving a tank steering robot with a single control stick. An invert feature controlled by an RC channel allows driving the robot inverted. Even non-invertable robots can benefit from the invert feature because inverted controls will allow the robot to be easily driven backwards, leading with the rear.

Selectable pass-through mode allows using a tank mixer built in to a speed controller, such an a Vantec, but still retaining the invert feature.

IMX-1 features include:
* Use a third RC channel to invert your forward-backward Y channel
* Failsafe on signal loss
* Tank mixing algorithm designed to give improved robot control over standard Elevon mixing
* Selectable tank mixing or pass-through behavior
* No need for line boosters when used with IFI speed controllers
* An LED provides feedback for proper operation
* Length: 1.9" Width: 1.25" Height: slightly taller than a servo connector
* Remote LED option allows you to mount the LED to the outside of your bot.

"Just want to give props to the Robot Logic guys. I installed the mixer in Psychotron this weekend and it works great. Great solution to a common problem. No more practicing driving upside down. I also like the failsafe feature."
