RC Plane Split Wheel

This is a heavy duty replacement wheel for my 80 inch Hanger 9 Piper Pawnee.
It should also work for most 3 to 4 inch foam / rubber tires for RC planes (23 -25 mm inner).
This wheel is designed to be stronger, having a thicker tire bead area and thicker walls.

Assembly uses 2 mm * 15mm screws, this is a hidden collar design. The inner wheel is put on the axel, then the wheel retaining collar, then the outer wheel. The two wheel halves are then screwed together.
note: the inner space between the halves needs to be very clean in order for the wheel to spin freely on the axel and wheel collar.
The hub cap should just snap in place but may require a drop of CA glue to stay on if printed with a nozzle larger than 0.2.

For best results print with ABS (PLA and ASA should work as well) at 100% infill, 0.2mm nozzle, 4 or 5 perimeters, 4 top and 4 bottom layers, supports are required.
