The magnums are indeed an option. but ive been thinking, since the great planes t-craft kit isn't 100% scale, and its a smaller airplane (the size my buddies call "bull****in' around scale"), i'll just go with a $60 2 stroke .32 for some peppyness. i'll save 4 strokes for the 1/4 piper cub i plan to get some day soon and go all out on.
