Hornetnz, go to post 35 of this thread and you'll see how I made the wheels. I did quite a bit of weathering, but it's not extreme and tough to see from that distance. I tried to match up with the actual photos I have of the real aircraft.
Lifer, This plane is quite large, I would guess a 23x10 would pull it faster than a 22x12. A pretty good amount of thrust will be needed to pull it though the air. Never know though, I've been surprised at what prop combination works best sometimes. There's also the need to slow it down on landing, but I enlarged the stock flaps and changed the hinges so they drop pretty far down, should provide plenty of drag if I do go to a higher pitch. It's not all about speed, I want the engine to wind out and sound good, as well as have plenty of thrust to climb out with authority.
