It is interesting that the power to weight ratio (5.468 lb – 1.8 HP = .0205) of the “new” Cold Duck” is almost identical to a typical 10.5 lb 2X2 ship with a 3.5 HP power plant (= .0208). Of course the typical 2X2 ship will have a wing loading of about 25 oz and the Cold Duck is only 19.3 oz. But I’m not sure if wing loading can be scaled very well because of the Reynolds numbers, e.g. 25 oz on 1000 sq. in. wing compared to 19 oz on a 650 sq. in. wing.
