Also the hinge location and type of flaps also need to be correct. If you did a P-47 it better have the linkage that moves the flaps down and aft and not just hinge at a fixed location. Doors need to be able to open, flaps, landing gear doors would need to work in the same manner as on the full size aircraft.
Museum scale with everything working and nothing on the outside of the model should look like a model airplane part. Hide the motor, muffler, etc...
