The Commander Side-By-Side provides an unusual gyroplane design in that it has side-by-side configuration seating. The gyroplane was designed to comply with the US Experimental - Amateur-built rules. It features a single main rotor, a two-seat open cockpit without a windshield, tricycle landing gear and a four-cylinder, air-cooled, four-stroke, 1150NaN0 Subaru EJ22 automotive conversion engine in pusher configuration driving the propeller though a Gilmer belt reduction drive.
The aircraft's 291NaN1 diameter Rotordyne rotor has a chord of 81NaN1. The Side-By-Side has an empty weight of 4850NaN0 and a gross weight of 9260NaN0, giving a useful load of 441lb. Optional equipment available includes a folding mast, hydraulic wheel brakes and an electric trim system.
