I got the idea from photos of an old "stick style" chassis. I made a pivot block using a rod end that attachs to the center of the chassis. Two lower links keep the axle from moving forward or back. Dual shocks per axle, and moa steering.
I made a fairly simple track set up. The drive sprocket is the same size as the one used on the Kyosho SR snowcat. The shaft is set up for a 8mm pin drive axle. The tracks are the stock Kyosho SR plastic tracks.
