History
Sanwa, originally as part of Sansei Electric Industry, specialized in the research and development of remote control devices in 1959. It merged with Sanwa Denki Manufacturing in 1965 and then became part of the SMC Group. In January 1974, Sanwa entered production and sales of transmitters for radio-controlled models and in December, became a member of the Japan Radio Control Model Industrial Association (JRM). In 1975, Sanwa became a division on its own, with an office in Tokyo. In August that year it launched its first radio-controlled transmitter, the Mini Propo, and in 1976, Sanwa became an independent company. Its M-sechs wheeled transmitter was the recipient of the Good Design Award in 1990. In 1985, Sanwa diversified into the production of remote controls for domestic and industrial purposes. Due to its reputation in the radio-controlled modeling industry, its main competitor is Futaba. KO Propo and Spektrum.Airtronics
F. Lee Renaud began his hobby in model aviation in 1942 with a Joe Ott kit; he began to fly competitively in 1947. While recovering from a heart attack in 1970, Renaud used his medical leave from his office-equipment company job to build radio-controlled airplanes. He formed Airtronics in 1971 to build and sell model airplanes and radio remote-control devices. In his first year, he turned over $40,000. Renaud earned a reputation with model aircraft such as the "Olympic", "Aquila", "Grand Esprit" and "Sagitta", amongst others. In 1980, he introduced the XL transmitter. Renaud died in January 1983, and his wife Barbara took over the company. In 1982, realizing that his company wouldn't expand on its own without financial backing, Renaud took on a partnership with Sanwa, which bought an undisclosed large stake in the company while the family retained a controlling interest. Under the agreement, the Renauds built airplanes whilst Sanwa took charge of manufacturing radio-controlled transmitters for the Renauds to distribute. As a result, Airtronics increased its sales from less than $1 million in 1983 to $3 million in 1985, and to $8 million in 1989 with a staff of 18 employees. The company continued as a family business until 2007 when Global Hobby Distributors took over distributorship. Following business restructuring in Japan, the distributor announced that their partnership came to an end in 2016 and the brand will itself be discontinued although still continuing under a new distributor, Serpent America, as Sanwa.
