The HS-127 was designed and built by Hutchinson in 1956 as a single seat,
V-tailed aircraft that incorporated
spoilers mounted in the
fuselage sides, above the
wing roots. The aircraft was constructed from
aluminium and employed a
NACA 65 (3)-618
airfoil. In 1960 Hutchinson constructed a new fuselage for the aircraft with two seats in
tandem and a conventional tail. The wings from the earlier single seat fuselage were used on the new fuselage. The designer incorporated split
trailing edge dive brakes and claims this was the first use of balanced trailing edge dive brakes. Both versions of the aircraft bore the same
Federal Aviation Administration aircraft registration,
N62P. The aircraft's
HS designation indicates
Hutchinson Sailplane. ==Operational history==
