Rcpilet---I once had the Dynaflite Super-D kit, and traded it unbuilt. I pulled a lot of info off various sites about it, the Scout, and Explorer. The Super-D is the only one of the three without flaps; it and the Scout both have the 180 hp engine, where the Explorer is 160. The Super-D is 22.9 ft long compared to 22.1 of the Explorer and 23 ft of the Scout. Wingspans are: Super D,32 ft, Explorer, 34.5 ft, and Scout, 36.2 ft. from what I can see, the fuselages are essentially the same, the pics i have show very little, if any differences between them. Maybe your info is better than mine. The cabins are the same width (2'6"), length (8'10"), and height (3'11") on all three. I have a lot of other size and performance specs if you are interested. That ought to be a nice build. I'd still like to do one some day.
