e: This is the vintage Tamiya Grasshopper that started it all. My grandfather bought it in the mid 80's and I got to play with it at his house once every ~2 years. I lusted after it on the top shelf in the basement for a long time.
Note the now bald original tires, and my kickin' video taking modification for personal amusement (I removed the scale driver and screwed in a tripod mount).
You can see in the front of the cockpit a funny little copper thing with little copper pads. Forwards/reverse is controlled with a servo that moves an arm that touches 4 different copper pads for two speeds each direction.
