Chris, my Mustang is still in the kit box. But it must have lived its life so far in a cool dry place. The wood is in perfect shape. Typical Sterling wood, you could bludgeon someone to death with the fuselage Lol. The Yak was much worse for wear when I got it. The ply was all de-laminated, and the fuselage was so poorly cut I laminated a new one. I'll probably do that with the Stang too, to help it stay straight and, in the case of the Yak, arrest any hairline cracks that might start on one side. I think the Fox .35 might have caused that to happen. I will not use any of the kit plywood, and decide on the rest as I build it. I'll probably start it this Fall. I'd like to use a Max-S .35 on it rather than a Fox.
I still need to make some exhaust pipes. That piece of blue tape has been on it for 3 years now.
Your old Yak looks to be able to fly again without too much repair. I like the silver wing, what is that?
