Thanks for the words of encouragement, the motivational photos, and the advice!
I looked into the Fiberglass Specialties replacement parts, but I'm considering scratch building a gun hood, and laying up my own cowl. If they don't turn out well, I'll bite the bullet and buy the FS parts.
As mentioned earlier, I'm working on gluing in the stringers, but I can't finish doing that until I've worked out the sliding canopy. I can't work on the sliding canopy until I assemble the canopy itself, and I can't do THAT until I purchase a block of balsa to replace the missing 2nd turtle-deck balsa block. [
] Should be able to get the supplies I need and work some more on the plane this weekend.
