Zane Adams two photos depicting Mike Mullins Helio Stallion N9991F was a series of AU-24A's that were sent to South East Asia but never sold to the South Vietnamese. They were under contract to the Royal Thai Air Force and later used by the Khmer Rouge AF. Armed with rockets, 20MM cannons, and a 500 lb bomb under the fuselage. Paul Davis was a tech rep for Helio and imported these back to the US. The airplane crashed when the prop went into deep beta, flying jumpers and returning to base. Only 18 Stallions were built and most of them are AU-24A's and only two fly today..
