The RC-3 Seabee was designed by Percival Hopkins "Spence" Spencer. An aviation pioneer who first soloed in a powered airplane in 1914, he designed the Spencer S-12 Air Car Amphibian . Construction of the S-12 began on March 1, 1941 and the small, two-seat S-12 prototype, registered NX29098, made its first flight on August 8, 1941.
2.400-2.485 GHz: 13-cm UHF Spread Spectrum band for general use (amateur radio license holders have 2.39-2.45 GHz licensed for their general use in the USA) and using both frequency-hopping spread spectrum and direct-sequence spread spectrum RF technology to maximize the number of available frequencies on this band, especially at organized ...
1:10 scale radio-controlled car (Saab Sonett II)A radio-controlled model (or RC model) is a model that is steerable with the use of radio control (RC). All types of model vehicles have had RC systems installed in them, including ground vehicles, boats, planes, helicopters and even submarines and scale railway locomotives.
Radio-controlled racing boats are designed for maximum speed and maneuverability. Various styles of racing include circuits of different shapes laid out on the water with buoys. The most common courses are the 1/6-mile oval that consists of 330-foot straight sections followed by 70-foot-diameter turns.
The Supermarine S.6B is a British racing seaplane developed by R.J. Mitchell for the Supermarine company to take part in the Schneider Trophy competition of 1931. The S.6B marked the culmination of Mitchell's quest to "perfect the design of the racing seaplane" and represented the cutting edge of aerodynamic technology for the era.
Early versions merely constrained the model to fly in a circle but offered no control. This is known as round-the-pole flying.The origins of control-line flight are obscure, but the first person to use a recognizable system that manipulated the control surfaces on the model is generally considered to be Oba St. Clair, in June 1936, near Gresham, Oregon.

The 600-690 hp (448-515 kW) Pratt & Whitney R-1690-42 Hornet engine was used to power Corsairs designated SU-1 to SU-4.The change in designation reflected their role as scouts (their larger engines and heavier weight precluded their use as floatplanes, and USN examples were only used on wheels from either carrier decks or land bases).
