This is Maynard Hill’s Sampey 404 which he used to set World Records in the 1960s. He was a model aviation pioneer and leader and an AMA President, but above all he was the King of the World Records. We doubt anyone else was so successful at making and breaking world records, at least not back then. His historic accomplishments continued over the years, the most recent being his transatlantic model airplane flight in 2003, at a time when he was legally blind.

Maynard Hill lived in the DC area and was prominent in his local RC club, DCRC. But DCRC was no ordinary club. What the legendary German Bauhaus was to architecture, the DCRC was to radio control development. Each year DCRC hosted Symposia and the “best and brightest” would come from around the country and present sophisticated technical papers. The DCRC was the avant-garde, the cutting edge of the industry and Maynard Hill was at its forefront.

Maynard began his assaults on the record books in the early 1960s after learning how the existing Russian record holder achieved his records with relatively crude equipment. Maynard Hill thought he could do better with superior American aircraft, engines and radios. In addition to this equipment and his own formidable skills in model designing and building, electronics and piloting, Maynard Hill had incomparable leadership abilities which enabled him to assemble the necessary teams of people to back him up and assure success. In those cold war days beating the Russian record holders was more than a personal triumph, it was a point of patriotic pride for modelers around the country.

Maynard Hill pursued the Third Dream of Radio Control from an early date. He transitioned from single channel escapement radios to crude pulse/mechanical systems then to the TTPW system of his good friend Walt Good, then to Space Control. When he began his world record attempts he used the most promising new system of that day – the Sampey 404. Maynard Hill employed two 404’s in his record attempts using one as a backup or alternating back and forth between the two (especially on duration and distance flights).

The cost of two Sampey 404s in today’s terms would approach ten thousand dollars. Maynard purchased them, with his own funds to maintain his detachment, although Sampey may have been willing to give him the radios in hopes of favorable publicity. Only the truly dedicated, determined to have the very best, would spend such a sum on model airplane radios but this was only the beginning of Maynard Hill’s expenditure of time and money in his quest. In the end it all paid off, and Maynard Hill assumed his well-earned place in model aviation history. And oh yes, Harry Sampey got that favorable publicity and shrewdly parlayed it into 404 sales. See Sampey section.

May Hill Sampey WorthPicture1
Maynard Hill’s other Sampey 404, had the trademark “404” insignia at the top but on this one only a faint vestige of these numbers is visible. Here is a picture of Maynard and John Worth preparing to break the closed course distance record with the transmitter visible in the background. Maynard Hill was President of the AMA at this time.

Here is a tired, reclining Maynard Hill using this transmitter to break the word duration record. If you look closely you can see some of the distinctive features including the hand cut relocation of the throttle control and the wiring to draw power from a car battery.

Other distinctive features on our transmitter include the 2 tiny push buttons on the right side (visible in the previous picture), the name “Hill” etched through the finish and the many technical scratch marks (arrows, letters, etc) to aid tuning and operation. This worn transmitter was as well used as it was used well.

Here is the cover of the March/April 1964 Grid Leaks picturing Maynard Hill using our transmitter in early season practice for the closed course distance record. The white noteboard or plaque at the top is the likely reason this transmitter lost its “404”. Maynard does not recall how this happened. We surmise that the whiteboard was secured with glue, 2-sided tape or the like, and when it was pulled off most of the 404 insignia came off with it (and the rest may have then been removed to “even things up”). If anyone has additional information about how this 404 lost its“404” please contact us.
