This is a slightly smaller paddle tire I designed for my Rustler VXL. The first one was great for really dry soft sand, but I think this one will do better in wet sand. It is 4.40" diameter and it fits on the PLA wheel I designed for this paddle sleeve This one has 18 slightly smaller paddles with an elliptical contact surface, instead of 12 larger paddles and a flat surface like the first paddle tire.
You can see the first paddle tire (red rim and white paddle tire) compared to this one. The paddle is a bit hairy. I am still working on the temp and retraction to reduce the fine hairs.
EDIT: Slo-mo video.
The narrow "pizza cutter" front tires and rims were inspired by the narrow front tires that came with my Associated RC10 GT back in the late 80's. I'll upload the rims and tires when I get the kinks worked out.
The neon green rims are Hatchbox / AMZ3D PLA.
