RE: Top Flite Giant P-47 Build
In my opinion scaling the cockpit in the razorback version, unless you plan on installing a sliding canopy, most of your work will be invisible between the pilot sitting there and the canopy frame.
I scaled out mine in my TF razorback 60 size and I spent a little fortune in a pilot and cockpit details and once it was all closed up all you could see was little of the pilot and the dashboard.
I think it would be different in a bubble canopy version.
As for wheels, I am not sure what's your budget is but I bought mine from Robart with 5" rims and tires you are looking to spend around $200.
Very scale like and it dresses up the bird on the ground like no other.
I have a similar set to my TF GS P-51 and they are really a show peace.
