[TC29] Snowmbile

As a motorcycle rider and enthusiast, I like building bikes. I figured the closest thing to a motorcycle that has tracks is a snowmobile, so that's I went for.
I want it large enough to use good old PF, for added RC fun.

First iteration for the front:

Compact enough, but the skis lack a degree of liberty.

Second iteration:

Now I'm looking into the tracks. Snowmobile track suspension system is a lot less trivial than it looks:

I'm not sure I'll replicate all the subtleties, because it involves a compact torsion spring which simply does not exist in the Technic world.
My third iteration on the tracks suspension is a basic parallelogram, so I'm still unhappy:


And that's the status for now.
