Oh, wow, that's a very ambitious project! In any case you're off to a great start and apart from the very detailed engine, the fire wall bulkhead looks fantastic too. What's the scale of your model? By the sizing you mentioned (the one with the 60cm wingspan), that should be around 1:16, in other words, twice the size of a 1:33 Halinski type of Spitfire. Very cool. You have my full attention
and I wish you a lot of success with the build.
Cheers,
Erik
