The Big Cootie is a modernized version of the Powell PH Racer biplane for homebuilt construction. The aircraft is a single seat biplane with conventional landing gear, designed for mild aerobatics. The fuselage is welded steel tube construction with aircraft fabric covering. The cowling is fiberglass. The ailerons are controlled with push-pull tubes. The wings use wooden spars with plywood leading edges.

The prototype, N84Z, survived an in-flight impact with powerlines during its initial testing. It was rebuilt at the Piedmont Aerospace Institute at Smith Reynolds Airport in Winston-Salem, North Carolina. A Continental A-80 80 hp (60 kW) engine replaced the Lycoming O-145 65 hp (48 kW) engine installed in the prototype.

The kits included all premolded composite parts. All metal parts and fuselage are welded. The wings and tail are attached like a glider and a removed in 5 minutes.

The Sherwood Ranger is a lightweight two seat open cockpit biplane, designed to reduce the cost of owning and operating your own aeroplane to the absolute minimum. One of its major features is that the wings can be folded and the aeroplane loaded onto a trailer in less than three minutes, thus eliminating hangarage costs by allowing the aeroplane to be stored at home. The performance and handling characteristics allow safe operation from unprepared grass fields as short as 250yds.

The Ranger XP was first flown in 1991, and the LW in 1994.
