The ESC has no markings for the wires. And I need instructions for the setup.

The wheels are sort of like a bead lock. The flat ring cpatures the tire bead against the wheel halves. The wheels aren't vented and don't use foams. So if they are done right, they are like balloon tires. Soft and springy.

If I can get it cleaned up and running, I intend to drive it. But it needs rear axles and I can't locate them. The dogbones slots are worn and need to be replaced. I doubt I will be able to locate all original parts like the speed control, but it would be fun to try. I have not stripped the transmission apart yet, but that and the shocks are next on the teardown.
