Thought I'd chuck this into the archives...just in case someone might be able to make use of it. Check out the detail in the first photo of this fellow's early 1960's Sabre !!!!

@Kim , I'm surprised you never got a reply in this thread you started. I had one of the Top Flite molded full fuselage, molded wing 18in wingspan Japanese Zero with Pee Wee .020 engine. Built it in mid school.

I think even today, such techniques are still worthy for consideration as a lightweight method for full fuselage construction. This now even extends to foam, too.

I built the Hurricane. The Hurricane has a good airfoil and I'm not 100% certain, but I think it's the Flite Streak ribs. It's a decent airfoil nonetheless. However, the molded shells split longitudinal because the only glue area is the shell thickness themselves. What needs to happen is that ONLY epoxy should be used. In addition, the entire fuse should be covered in lightweight glass. Top Flite suggests silkspan and that would be the very least I would want and if so it needs to be heavy GM silkspan.

My Hurricane flew well even though I've heard others not doing well. I think my only real complaint was the small elevator. They did this to make it more scale like but I would increase it.

I've built the P-40 scale model with shells and also the P-47 with shells. These are roundy rounders but they're cool. My P-47 has a Mccoy .19 in it.
