The Wonder is best described as a very fast, go-where-you-point-it, turn-it-quick-or-it'll-be-gone kind of plane designed for hot-thumbed R/C pilots. With an .09 or a .10 size engine, the Wonder is actually a very nimble, aerobatic, smooth flying sport plane, but with a snarling .15 or .19 up front it's a hand- launched hot rod! Landings are no sweat thanks to the thick symmetrical airfoil and the light wing loading. Specifications:
Wingspan 37 1/2 sq.in. (952 mm)
Wing Area 338 sq.in. (25 sq dm)
Weight: 26 - 38 oz 737 - (1077 g)
Wing Loading: 11.1 - 16.2 oz/sq ft (423 - 4943 g/sq m)
Radio Required: 2-Channel (ail, ele) or 3-Channel (ail, ele, thr)
Recommended Glow Engines .09 - .19 cubic inch (.58 - 1.23 cc) 2-Stroke
Special notes about electric from Dave: This model makes an excellent electric "muscle" model. Often overlooked since SIG does not offer an e-version or any electric power system setup info. It's easily adapted. Below are my suggestions for a range of practical to extreeme power systems.
