A newbright sled would make a decent starting point, but they are out of production. Besides, getting certain replacement parts (mostly cosmetic) would be difficult at best. Hence my desire to use parts from current products, modded as necessary.

Before I start this, I really want to find a tread solution that has the "float" (thanks redshift for that point) and durability I'd need. Chris's tracks, while small, seem like a good solution once modified as needed. I would disassemble them and restructure the wheels/drive unit to be more flat. If I can do that, it looks like it would give me around 5-6" of tread length. May be a bit small for 8th scale, but certainly fine for 10th scale.

Yeah, sleds are power hogs, but I do have a Medusa 36-80-2000 motor currently not in use. That should be enough power on 5s for a 10th scale vehicle I would think.

Suspension is not really important to be honest. If the snow is hard enough to make it required, I would be using a wheeled vehicle anyway. This would be for the fluffy/deep stuff that would cause a normal vehicle to simply dig itself into a hole. If I put suspension, it would be most likely in front only and mainly for looks.

Chris, where can I get a set of those treads you have in your pics?
