The Helio HST-550 Stallion was an STOL utility aircraft developed in the United States in 1963. The prototype flew in July 1964. Initially conceived as a turboprop-powered variant of the Helio Courier it eventually emerged as a completely new design of the same general configuration and much of its design was initiated from components used in the Helio H-500 Twin.
