Continuing this one to it's own thread from the Airfix 2013 one, I thought it worth a discussion should anyone else be considering this conversion (Or an enterprising aftermarket company would like to try!)
As far as I can work out the differences are:
(i) Different, asymetric canopy on NF10
(ii) Staggered seats
(iii) Different shaped tail fins
(iv) Cannons
(vi) Different shaped nose (radome)
The big question is was the whole fuselage nacelle forward of the wings a different shape? The cockpit was wider, but was the fuselage as well?
