Years ago I did the same with a 1:32 scale Spitfire, I just didnt have the experience knowledge or anything else, ended up with a load of bits all out of shape covered in paint and glue. That's why I thought these two kits would be ideal, to see if I can learn enough to justify things like an airbrush etc. I did one closed up, so the other has two engines which is lucky because I broke some bits and lost one to the carpet. One engine will go in the Spitfire, the other will be as you say on a rack next to a Mustang P-51A in an imaginary "hey guys, will this fit in that" scenario.
