Ultra Light Wheels for Park Flyers

A friend and fellow modeler (Bob R) who is very creative when it comes to re-purposing everyday items, wanted to replace the small foam wheels on his HobbyZone Super Cub.

His goal was to make the wheels larger, wider, softer and lighter so that the Cub could take off from a grass flying field. His approach (in my opinion) was pure genius. Each hub was made from two plastic water bottle caps and a coffee stir straw for an axle. The core of the tire was made from a slice of a foam pool noodle (centre hole already extruded) with the corners rounded on a disc sander. The smooth outer skin was achieved by cutting the ends off of a 30cm (12in) black party balloon and stretching it over the foam core. A little dollar store craft glue was used between the balloon and core center and then the two bottle caps were glued back-to-back in the centre hole which pulled and held the balloon skin in place.... Simple, inexpensive and they work like a charm.

After seeing these wheels, I decided I wanted try making a pair for myself. I followed Bob's approach with the exception of making the hubs. Having access to a 3D printer, I just had had to design and print a set of uber-light hubs. The two hub halves are designed to accommodate the 14mm long stock Super Cub axle shaft and plastic hex-nut. Being much wider than the stock wheels, the outer face of the hub was recessed but this gives the wheel a nice look and conceals the plastic nut.
