Hughes OH-6 Cayuse Helicopter

Model Information

This model is highly detailed, and was built from over thirty reference images, blueprints and schematics. Included are nine 4k baked textures that were created with global illumination with V-Ray. This model would be best used for cinematics, infographics, photorealistic rendering, and diagrams.

It should be noted that there are some slight variations of the OH-6 depending on the year built. This model was based on the first variant. Some of the variations are simply the base helicopter with the doors removed, and armament systems added.

Description and History

When the US Army put forth a requirement for 4,000 new helicopters to fulfill a variety of support and combat duties, a number of helicopter and airplane manufacturers submitted bids for designs. Ultimately, Bell and Hiller were selected to build prototypes to compete in the Light Observation Helicopter (LOH) program.

In a controversial move, the newly-formed Hughes Helicopter was also permitted to participate. Though the Hiller design was generally considered to be the best of the three entrants, the industry was stunned when Hughes was announced the winner of such a massive contract. In its favor, the Hughes 369 was a remarkably small and agile design, but the project was so fraught with cost overruns and engineering difficulties that the Army cancelled production after only some 1,400 of the projected 4,000 had been built. The type did prove valuable in Vietnam but was soon relegated to second-line units after the Army awarded a new LOH contract to the Bell OH-58.

Despite these difficulties, Hughes proceeded to develop a civil version, the MD 500, that has become one of the most popular civil helicopters in history. The latest versions include the 520N/600N which use a NOTAR (No TAil Rotor) system. Instead of using a traditional tail rotor to counteract torque, NOTAR employs an air jet at the end of the tail boom. More advanced military versions based on the civil variants have also been developed, namely the 500MG and 530MG Defender series.

In addition to the US Army and other militaries, major users of the MD 500 include police departments and border patrol agencies. Including all variants, over 4,000 MD 500 helicopters have been built including about 100 NOTAR models.
