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 snarlin' .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.
