The Stallion is specifically designed for operation from unprepared fields and is equipped with a full complement of STOL devices. Design of the Stallion began in 1963, and the first models were produced in 1966. The Helio Aircraft Corp. was founded in 1948, and its first prototype was a converted Piper Vagabond. Then Helio became a part of the General Aircraft Corp. and produced the Super Courier and the Stallion. Both aircraft are similar in construction. The Stallion is powered by a single 680-ehp turboprop engine driving a three blade reversible-pitch prop and fed by wing tanks with a capacity of 120 gallons.
Its all-metal cantilevered wings are equipped with high lift slotted all-metal flaps, fabric-covered balanced ailerons, and full-span automatic leading-edge slats. The tail unit features a one-piece horizontal surface with combined trim and antibalance tab. The cabin is protected by a crash-resistant tubular frame. The Stallion’s accommodations provide for a pilot and copilot up front with either eight passengers on bench seats or six passengers seated individually. Access is made through a door on the port side near the pilot, an optional starboard door, and a double cargo door on the port side. The double door is in two sections—the forward half hinges and the rear half slides. The rear half can be opened during flight for cargo drops or parachutists.
