Vietnam War Helicopter Model Dioramas                                              OH-6A Cayuse

The OH-6A was designed for use as a military scout during the Vietnam War.  In 1968, Cayuse was used for command & control, observation, target acquisition, and reconnaissance missions.  The OH-6A replaced the Korean era OH-13 Sioux & OH-23 Raven helicopters.  The Cayuse had a single articulated four-bladed main rotor, a metal two-bladed tail rotor, and a V-shaped tail.  The aircraft was powered by a single Allison T63-A-5A (285 shp) turboshaft engine and had a cruising speed of 125 knots (144 mph).
