Here's my first plane assembled, a Sopwith Pup. It's an old Airfix kit. I thought I would try assembling the whole thing first, then painting. In hindsight, I should have left the pilot out and painted him separately. But this is the first plastic non-gaming-specific kit I've done since I was a kid, so I was just following the instructions.
It was a little trickier than I thought. The cross-piece for the landing gear was missing, so I used brass rod and had to guess at the length. The upper wing was a pain in the ass to attach, as all its held on with are the struts connecting to the lower wing. But it turned out OK for a first try. I need to touch up the engine cowling a bit with some filing and maybe a bit of putty.
Unlike some of the other planes, this one is probably not going to be terribly interesting to paint.
I just cracked open what may be the next plane, a Fokker DR.1. It's another Airfix, but the quality is horrible compared to the Pup. More to come as I continue...
