Richard,

The Connie was lofted up from three view and Frank drew his own structural plans. The construction is traditional, formers of plywood and balsa, with planking on the fuselage, ribs and sheeting for the tail and wings. There is a lot of plywood for the LG mounts, main spar, nacelles, and firewalls. I believe that the Connie is glassed with .75oz cloth. I do not know what the finish color paint type is.

In regard to OS, In my experience, the only bad OS has the wrong fuel in it or a bad glowplug. As I mentioned in my edit of the lead thread, the engines are 108FSRs instead of the 91FX's. I wonder if the 91FX would have the edge on power, being a later design?.
