According to the Lieutenant article in the January 1958 issue of Model Airplane News, the original weighed 30 oz with a Fox 35 and flew 80 mph. It had a very thin wing, about 12.5% at the root and 25% at the tips. with no thickness taper. It had a straight LE with an elliptical TE. Based on the Dave Day charts for classical airplanes, it had a 49.5" span. Based on that, rough measurements from the magazine plan, it had approximately 450 sq in. At that weight and power, it probably does not need flaps.
Interesting airplane. It would be good to see something like this at VSC. With that thin wing, I think it would still need to be kept light to fly really well.
