Abstract: A roadable aircraft includes three symmetrically lateral flight surfaces, comprising a forward main wing generally centrally located relative to the fuselage or body, a rearwardly located stabilizing surface acting as an empennage support, and a rear stabilizer and elevator located at the rearward end of the empennage tail booms. The wheel or landing gear configuration is of a rhomboid pattern, with forward and rearward main wheels along the centerline of the craft, and left and right outboard wheels. The outboard wheels extend and retract individually to a limited degree to compensate for centrifugal forces in ground operations, and together in coordination with the main wheels for flight operations. The powerplant drives the rearward main wheel from one end of its output shaft, and the propeller from the opposite end of the output shaft.
