Re: 4 Wheel Drive Too Much Traction

12 tooth on the transmissions and a 30 tooth on the wheels.

That will increase your reduction to 11.67:1, drop your top speed to 9.65 ft./sec, and give you enough torque to turn.

The sprockets you want are available from both AndyMarh and VexPro.
This is the best, most straightforward advice you've received so far. Do this.
