==Early history==
The company was founded in 1969 by Bob Boucher and Roland Boucher. Their goal was the development and production of a high-performance radio controlled sailplane for use in AMA-certified competition. That first sailplane, the "Malibu," finished third in its very first outing in San Jose that same year. Bob Boucher would use a Malibu in 1970 to set a closed-course world record for soaring. His record flight of 302 km took place at Waimanalo Beach, Hawaii. The introduction of the Fournier RF-4 electric R/C airplane in 1971 marked the debut of the world's first practical electric-powered model airplane. This would be the model which Roland Boucher would use to set a world record for duration and distance with a flight of one hour and a distance of on a single charge. Since no official categories for electric flight existed at the time, neither the AMA nor the FAI recognized the record.
The Northrop Corporation awarded Astro Flight a contract in 1972 to develop a low- altitude electric surveillance drone. Project manager Bob Boucher along with Roland Boucher and their lone employee Dave Shadel finished the design in only six months. The result was the Model 7212 flying wing. With a wingspan of 8', the 7212 was powered by three of the company's Astro 40 ferrite motors each turning a three-blade, 8x8 propeller. The 7212 would set another unofficial record in August 1973 by carrying a 7.5 pound lead payload over a closed course for an hour and twenty minutes at speeds reaching .
