Yes, I confess, fidelity of shape matters to me. A lot, to put it in decidedly American terms. The Academy Spitfire XIV?
!!!
So there are a number of kits out there with mild to moderate shape errors that lend themselves well to Whiffery without a lot of necessary surgery. The following are ideas that work
With the known issues rather than against them and provide a knowledged observer a double take.
1:48.
Hobbycraft/ESCI MIG-23. Slightly stretch the nose right behind the radome say 10mm or so, rescribe, aftermarket tailpipe, add a few MLG well doodles and it's a prototype interceptor. The overly squished canopy will amplify the look of the nose stretch.
Fujimi Me-110. Since the aft fuselage is markedly too short, make the vertical tails smaller and rounder, fixed gear/spatted. Graft Hobbycraft Me-109B, C, or D noses onto wing for engines if in lines are preferred. Cloth outer wings.
Italeri Re-2002. Convert to fabric wing as an excuse for that crazy thick wing, delete the head fairing altogether, open cockpit, resin Wildcat prop, large spinner, simple paint scheme. It might look quite good.
Hobbycraft MiG-17 retool. T-tail, relocate speed brakes. It's also a great candidate for major surgery projects, but that's for elsewhere.
