With traditional technology, a micro receiver has lower sensitivity (control distance) than a full-sized receiver. Corona receivers use a state-of-the-art receiver chip, careful filtration, and DSP technology to achieve full-range while remaining small and lightweight. With this combination, the Corona receivers have capabilities usually only found in older technology receivers weighing several dozen grams. Because of their light weight, the Corona receivers can be used in many applications including indoor electric aircraft, 3D fixed-wing airplanes, and outdoor glow planes of several kilograms or pounds. With a sensitivity of better than 2µV, the Corona receivers have a full range. These receivers use dual tuned RF circuitry with dual ceramic IF filters which ensure an ultra narrow selectivity to more effectively reject adjacent channel interference. This is especially important when flying high traffic areas where many transmitters may be operating near each other.
