Roger, that is an interesting approach to the engine cowling.Thanks for the pictures. I ended up pretty much where you will, but from a solid block, a lot of discarded balsa and elbow grease. You've got it planned out very nicely.
No, not yet quite ready to cover mine, Frank--I need to finish repairing the lower LE sheeting, got one wing done and it looks very good, one to go...I have put the rib cap strips on the top surface but not yet on the bottom. Now working on my cooling-air vent; I'm sorta stealing your grillwork, but on the under side rather than the top. I'll post some pics Mon.
Also did some preliminary work on the canopy/windscreen/whatever: Got a tagboard pattern cut down close to size. I guess I'll just let the canopy overlap the balsa sides and glue it on. May not be the most elegant approach, but it oughtta work and at least it's simple. Any other ideas, I'd be glad to hear.
I'm almost sad to be approaching the end of this very interesting build. I've learned several things from it, for instance how to make formed alum. landing gear (thanks Frank); how simplY a cowled vented engine setup can be done; ditto a formed-balsa builtup fuselage. How to build a wing around an engine pod, then integrate it into a full fuselage. I don't think I've ever built a reflex airfoil before, what is apparently called a "pollywog", on a builtup wing. Never before used a true spinner on a 1/2A rather than just a spinner nut (thanks again, Jan). And of course there's the shared camaraderie of an online build (thanks for making it possible, Robert). Thanks, Frank, Roger, Bill, all who have helped make this a most enjoyable experience. I'm already looking forward to the next one, whatever it is.
And I'd like to thank my wife for putting up with me, and my parents for having me, and my agent for...hey, it's the Acadamy Awards!

P.S. all-together weight now approaching 9 oz., no problem, still very much within reason and target. Better news: The CG is creeping backward with the weight gain! Balance may not be so far off when all is done. It's probably an inch or so ahead of plan location right now. That 1/2 oz. weight gain I've documented is virtually all aft (tail wheel, capstrips) and has pulled the CG back about 1/2 inch. Gooder and gooder...
