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
