Oh man!! Have I been out of the loop! I haven't checked on this UCD thread for a few days and I see there has been some new posts.
Kokamo, nice idea about leaving off the blocks for the cowl. That's ingenious! I love it. I have a new UCD coming today and when I start building it I think that's what I'll do. I got to thinking that what might work also is to use some blocks (smaller ones) inside the firewall and screw into those. That way I'll be beefing up the firewall at the same time. Hummmm........ I'll have to ponder that one. I'm going to install a smaller throttle servo too. I think it was Barry Craizer that mentioned that. Oh boy!! Oh boy!! Another plane to build.......
