For the camera I used a Canon EOS Rebel 35mm SLR with Fuji ISO 800 print film, and along with the set of prints I had it developed on CD ROM (local photo shop runs a decent deal on that). For the cloudy weather, I used a shutter speed of 1/100.
To apply the special markings required just a little bit of surgery because the markings were designed for a later version of the MiG with the trailing edge extensions to the tail. It's probably not totally authentic to have this markings on an early model, but the kit was given as a gift and I like to dress those up a bit so they look nice when I send pictures to the "giver"! :)
I'll have to go look at the underside to answer the question about the engine housing - I'm on the road for the long weekend and am having a hard time visualizing it to answer your question!
