There was a Internet presentation on the final FAA Rules last week. I personally didn't understand much of it. Darrell said he'd be sending out more info on this subject. From what I understand since we are a Chartered
AMA Club we shouldn't have too many problems with the new rules. By the way, they don't take effect until October 2023.

History of RC aircraft
It all started with Dr. Walter Good and his twin brother, Bill, in 1937. They could never have imagined what the hobby of RC model airplanes would be today. I’ll take you with me as we travel along the timeline of RC development since the Good brothers made their historic flights at the Kalamazoo, Michigan, airport. Those first flights were made with an 8-foot Free Flight (FF) model into which the brothers installed their primitive RC equipment. They designed and built their Big Guff airplane in 1938 specifically for RC. That same year, Ross Hull, an avid modeler from Australia, flew a 13-foot RC glider at a famous glider site near Elmira, New York. As early as 1938, Leo Weiss was recognized as describing the first tone reed system, an eight-channel radio system. Raytheon developed its ultrasensitive RK-62 tube, which enabled the development of the single-tube receiver. Howard McEntee published details with schematics for his twin-frequency transmitter in 1939. One of the earliest publications of a multifunction, single-channel RC system was by Thracey Petrides and Leon Hillman in 1941. The U.S. Army used RC airplanes called Radioplanes as artillery target drones during World War II. FCC Order 130-C went into effect on March 1, 1946, and created the 6-meter band allocation for the amateur service as 50 to 54 MHz. Many modelers, such as I, quickly learned some radio theory and Morse code to be able to fly on the 6-meter band, which gave them an almost personalized frequency at local fields.
The first examination-free frequency was provided by FCC in 1949. It was 465 mc and was limited to 5 watts. That same year, Ed Rockwood developed a multichannel system, which was the first commercial venture for an audio-frequency-modulated reed radio. 1952 was a big year for RC modelers when the FCC granted use of the 27.255 mc frequency as the first license-free and test-free band. The power output limit was 5 watts. In 1953, Frank Schmidt made and sold a complete five-channel reed set based on the Rockwood design. In 1954, Don Brown developed the Galloping Ghost system, which might have been the first multicontrol system. He called it the “crank system.” During these years, transmitters were quite large with many tubes and heavy batteries. Bramco, Inc. introduced its Control Box Transmitter that was advertised as “the control box for controlling your model with the reflexes and coordination of a real pilot.” Jack Albrecht built what is thought to be the first handheld transmitter in 1956. Bob Dunham started Orbit Electronics in 1958 and produced a popular reed system with a handheld transmitter. Before this, several top pilots were flying Bramco radios with ground-based transmitters. Bramco quickly saw the popularity of handheld transmitters and began producing its own.
1960 saw the first commercially available proportional system, Space Control, introduced by Zel Richie. Space Control was engineered by Hershel Toomim and produced by his company, Solidtronic, in Van Nuys, California. Meanwhile, in 1960, Don Baisden submitted a proposed article to Grid Leaks magazine on his single-channel Galloping Ghost pulser and another for his rudder-only pulser that was later kitted by Ace RC. Also in 1960, Howard McEntee came up with a simplified version of a pulse-proportional system that used only a single tone and added the feature of being able to vary the pulse rate of the tone, as well as achieve a second function with only one tone. Howard’s system was referred to as the “Kicken Duck” because the control surfaces flapped like a duck’s wings. More advances were seen in 1961 as the Bonner relayless servo, the Transmite, became commercially available. The first jet model was flown with a Dyna Pulse Jet and a reed radio system. It had Jerry Nelson as the pilot. Don Brown built his first Quadraplex proportional RC system by hand as Carl Schwab, who designed the electronics, provided advice and assistance by telephone.
In the early 1960s, the move from reed systems to proportional systems was gaining ground. Three more significant advances in RC came in 1962. Airborne Control Labs introduced its pioneering feedback proportional system in April 1962, including incorporating the receiver and servos into an airborne “brick.” The first commercial digital RC system was flown by Doug Spreng. The radio was named Digicon. 1962 also saw the first commercially produced four-stick proportional radio, the Astroguide, by Klinetronics. In 1963, Howard Bonner’s name was in the news again when he introduced his eight-channel Digimite system. One of the most significant developments arrived in 1965 when the FCC granted five frequencies on 72 MHz band with 80 kHz spacing. In 1966, Proportional Control System’s (PCS) revolutionary low price of $299.95 for a complete proportional system with servos and batteries shook the RC world to its foundations and led to the demise of several competing manufacturers. Most of the systems at the time sold for approximately $500. Phil Kraft introduced his Gold Medal Series proportional system in 1968 after winning the gold medal at the Corsica, Italy World Championships.
A major improvement to RC systems came in 1982 when JR Radios offered an array of programming features. These computer radios allowed pilots to program the transmitter for many different models. The programming started with naming the airplane, and then setting various parameters such as servo direction, servo travel limits, dual and triple rates, mixing of various controls, and exponential travel curves that could be customized for each pilot and model. In 1987, the FCC granted additional channels on the 72 MHz band, and the following year granted more channels on the 72 MHz band, with 20 kHz spacing referred to as narrow band. In 2004, the first commercial RC system using spread spectrum technology was introduced by Spektrum. It operated on 2.4 GHz. Paul Beard developed spread spectrum modulation (DSM) using 2.4 GHz. In 2011, Futaba introduced Futaba Advanced Spread Spectrum Technology (FASST). The next year, Futaba introduced S.Bus protocol using one signal cable to control multiple servos. Improvements in reliability with lower costs have continued to the present. I’m sure I missed some milestones along the road of RC development, but I believe that I captured enough to give you a picture of how our great RC model aircraft hobby has progressed since the Good brothers started it off in 1937.
