Aerobatic flying just doesn't get any better than this Pitts ARF. The classic lines of a biplane coupled with the
radial cowl, add excitement to the maneuvers you love, knife edge, split S, lumcevac, torque rolls, snaps, and
ground-hugging inverted flight. What's more, we've engineered this ARF to get you into the air with a minimum
of fuss. So take a few minutes to carefully read the introductory material and then get to work. You'll soon be
out at the field with a classic aerobatic champion!
