Wow, an entirely positive or at least neutral response to an aircraft addition on the Wishlist. Although it is early days yet!
I was thinking for the 3d model all the components are already there. Basically the wings from the AH Spitfire Mark I model, and the fuselage from the Mark V. I'm sure it is still a fair bit of work though, depends how compatible all those little vertices and triangles are.
Karnak might be able to advise about which exhaust stacks and prop was used. I had understood that the A was an earlier model than the B but stand corrected. I bow to his greater knowledge on the subject. Regarding the flight model the A might have a
slightly lower power output that out current Mark V, and I dare not hazard a guess regarding the comparative weights.
Surely there are more future members of the 303 fan club out there?
