You guys got to try this:

Get one of the RC Racer units. You know how the steering motor only turns a little to the left and right with the remote?

Well, connect a small axle to the steering motor and the polarity reverser. Like this:

Connect a battery box to one end and a motor on the other end. When you flip the toggle on the remote the steering motor turns and activates the motor connected to the pole reverser.

The RC unit steering motor has a spring loaded “center return” so when you let go of the toggle on the remote, the pole reverser returns back to nuetral or an off position.

It’s really cool! I guess it is called a mechanical multiplexor? Is that the proper name? Or is it just a mechanical remote of some kind? Either way, it is a way to get a third motor control from the RC Units. CAUTION DO NOT use with Racer Motors!

I had successfully used just such a mechanism in 2006 at Brickfest in DC with a remote control I used to run part of my GBC components. The remote allowed users to steer a chute left or right and try to make the balls hit a moving target. The “return-to-center” (off) part was great in that when they stopped pushing the stick, the chute stayed still.

The pole-reverser fit the remote so well it almost seemed like it was designed to go there. It was a little spooky.
