Hackenberger 1A
The Hackenberger 1A is an evolution of the model H. Similar in its design, but larger and more streamlined.
Built in 1935, the single place 1A extremites of the elevator had twin stabilizer/rudders.
Those rudders were actually braced onto the rear of the fuselage and only a single strut balanced the elevator above the stabilizers. The fuselage curved upwards at both ends, connecting to the leading and trailing edges of the parasol. Somehow the angle of the elevator was varied at its joining with the parasol/fuselage.
Registered N13974 c/n 2, power was two 20hp Irwin Meteormotors, changed to 40hp Continentals in 1938.
Hackenberger H / Helioplane
A 1930 twin-engine flying pancake-type with heart-shaped parasol wing built by A L. Hackenberger.
The Hackenberger H, or Helioplane, was powered by two 4-cyl “Scroggies”.
The aircraft was registered NX18966 c/n 5H-1 (as H) as a single seater.

Gyrodyne XRON-1 Rotorcycle
In 1956, Gyrodyne entered the competition to produce a single seat “personal” helicopter for operation off destroyer heli-decks for fleet observation, and for battlefield support, and built ten examples of the XRON-1 for the U.S. Navy. These also had a coaxial rotor layout and a 40hp Nelson H.59 engine – later replaced by a 60hp Porsche. This experiment led to development of the QH-50 unmanned drone versions and Gyrodyne delivered over 60 production QH-50Cs.
The inverted V-tail assembly is for stability only. All control is achieved through the overhead rotors. A feature is tip brakes mounted on the ends of the rotor blades which provide smooth directional control.

Gyrodyne GCA-2
The Gyrodyne Company of America was established by Peter J. Papadakos in 1946. Gyrodyne acquired rights to the five-seat Helicopters Inc. (Bendix) Model J and developed this as the Gyrodyne GCA-2 (N74101). The GCA-2, an all-metal helicopter, had a coaxial twin rotor layout, with a five-seat cabin and a rounded fuselage with twin fins. It was subsequently modified to become the GCA-2A “Helidyne”, with twin 100hp Continental auxiliary engines mounted externally on strutted outriggers to give additional forward speed. It flew in this form on 30 November 1949.
A further development of the GCA-2, serial number N6594K, first flew on April 25, 1952 piloted by Jim Ryan as the GCA-2C. Convertible to an ambulance with three litters.
