My beater plane is a World Models Aircombat Zero. It's not pretty and looks nothing like a zero. Since it's a .25 size, it's small enough to fit in the car with the wing on. I've flown it with 3 different engines, Saito .45, OS .25 FSR, and OS .32 FSR. The .32 is what's in it now. This plane flies great, and is plenty fast. I often fly it in conditions that others won't, cause after all, it's my beater plane.
