That is what I thought 4 Inch wheels.. Tell me somthing when modifiying the wheel Wales to fit the 4 inch tires, did you have to make any structural changes on the wing.??

Wheels are Robart 4" aluminum. They don't come smaller than 4" in diameter. You can order them directly from Robart. I'm using the stock pushrods, but you can install pull-pull on the rudder.
