You shouldn't build a giant seesaw for your multi-ton off-roader but you can totally build one for your little RC Cars. TrophyRC ... you can try out a prototype that the developer made last ...
The build began as a simple two-motor, skid-steer RC car build with a fan for suction. Controlled by a smartphone app, a cheap Arduino board with an HC-05 Bluetooth module ran the show.
