brushless motor electronic speed controller

Loading mechanism of the disk is defined as the ratio between the total mass of the plate area rotors. Most of the disc rotor system allows more air to a more efficient focus. Appointments small rotor blades hovering over the rotor speed and efficiency of compact systems.
As brushless motor electronic speed controller with engine load is low production difficult Robinson R22. This improves performance, relatively low production R22 swim a Lycoming piston engine. According to the startup disk to the end of human powered helicopter. The low productivity of human beings requires a very large rotor. Students from California Polytechnic State University in San Luis Obispo is human-powered helicopter, weighed 250 pounds, including the driver's power / energy. He had a rotor diameter of 100 m, and he was the only one to fly. In December 1989, flew 7.1 seconds, reaching a height of 20 cm and was built to compete for the Sikorsky Prize, offered in 1980 by the American Society of helicopter. The price is $ 250,000. When the wholesale rc helicopter blades crew can stay aloft for 60 seconds and reaches a height of 3 meters, the price is not in demand.
Unlike a helicopter floating units high. For example, three programs Sikorsky CH-53E Sea Stallion 4380 hp General Electric T64-GE-416/416A production Turbomeca each use. The gross weight of 73,500 pounds and has a rotor diameter of 79 m. CH-53 is a deformation of the rotor in focus is so strong that it is almost impossible. Moreover, the high prices of helicopters to drive rapid decline, AutoRotate harder. Under load, the disc still has a V-22 Osprey tiltrotor. It consists of two rotor diameter of 38 meters and a maximum gross weight of 60,500 kg. To swim using two Rolls-Royce Allison T406/AE 1107C-Liberty production Turbomeca 6150 horsepower each.
