Pat, I'd say that Imperial would fly fairly well. A few years ago I spotted the Imperial in a photo, found some plans and decided to profile model it. I didn't like the thin airfoil so increased it by about 4 mm and flattened the curve at the thickest point to TE. The motor was an old Sabre 19 (!956 or thereabouts made in Australia) A sweet little number with a portside exhaust. So I decided to clip an outboard wing cell and mount her on the inside, no exhaust system so made one of my own tubular bells type! I notice the pressure plug has blown out. ( Engine ran better on uniflow) Adjustable leadouts and in an effort to save tail weight, I filled the rear fuz and tail with lots of O's. ( Then had to add tail weight!) It's a light model and flies very nicely, more like a bigger plane in some ways. Since then I have built 2 more for buddies with 4 stroke 30s. I have lengthened the fuz on both. One is yet to fly due to lock down, ( Photo attached I hope! Last time I tried that it wouldn't stick.) The other is a good plane and well matched to the 4 stroker. ( Was planted, since repaired and flies just as well as it did new.) I like the slimmer fuselage, forward cockpit and forward cantered undercarriage. I'm a sucker for retro styling with ink line detail and automotive clearcoat finish.
