How's the Model Tech P-47 Razorback?
I have a set of 2 3/4" wheels from a previous plane. Before I investigate whether I need to modify the wheel opening I'm going to taxi it around with these wheels. If it does taxi well, I will remove the plastic wheel well inserts. When I first assemble it I thought there was enough room for this size wheel. I will just need to rebuild the wheel well opening.
If all else fails I will either fly it as is or use the fixed landing gear.
I'll let you know how I make out.
