UM Wheel Hub

I was tired of the stock wheels that came with the various UM planes from Horizon Hobby and E-Flite; I found that the lack of a solid hub made the ground handling characteristics a bit unpredictable, and the foam wheels would often roll to one side on the axle. Wanting something more like the lightweight Dubro wheels but not being able to find any in the size of the stock wheels, I designed these to solve that issue.

You will need to print two parts and the hub is assembled with a small dab of epoxy around the base of the hub where it transitions from horizontal to vertical.

Weight increase over the stock wheel is 0.15g with paint.
