. The Lockheed F-117 Nighthawk is a stealth ground attack aircraft formerly operated by the United States Air Force. The F-117 was a 'black' project, an ultra-secret program for much of its life, until the late 1980s. The F-117A's first flight was in 1981, and it achieved initial operating capability status in October 1983. The F-117 is shaped to deflect radar signals and is about the size of an F-15 Eagle. It shares many components with the F-16 Fighting Falcon, F/A-18 Hornet and F-15E Strike Eagle. The single-seat Nighthawk is powered by two non-afterburning General Electric F404 turbofan engines, and has quadruple-redundant fly-by-wire flight controls. What does PNP mean? PNP stands for plug and play, and describes a model that is somewhere between Almost Ready to Fly (ARF) and Ready to Fly (RTF). Among the penalties for stealth are lower engine power thrust, due to losses in the inlet and outlet, a very low wing aspect ratio, and a high sweep angle (50°) needed to deflect incoming radar waves to the sides. A PNP model has the motor, ESC, servos and some radio gear installed but is missing the receiver, transmitter, batteries and charger. With these design considerations and no afterburner, the F-117 is limited to subsonic speeds. The fuselage is both strong and extremely light, designed to withstand the occasional crash landing. Starmax have worked their usual wonders in the finish and design of this foam structured plane. It is complete with a detailed paint
EDF - Electric Ducted Fan Jets, are propelled via a strong electrical motor (usually brushless for extra speed and power) that is blown down a duct to focus the airflow and provide 'vectored thrust'. Ducted Fan jets come in 3 standard sizes with the large sizes usually providing more power and speed. 50mm EDF, 64mm EDF and 70mm EDF radio controlled jets are all available. All EDF Jets are usually at least 4 channel and have enough power to do inverted flight and great stunts! Not for beginners.
