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.

What is the best energy source for the RC helicopter gyro store

What is the best energy source for the rc helicopter gyro store? Two variants of the turbine or reciprocating engine. Turbomachines the same basic structure of the jet engine, but the energy of the expanding gases may be used to drive a turbine to produce thrust position. The engine is equipped with gear that causes the main rotor of a helicopter transfer. Also controls the piston engine, the output shaft of the main rotor transmission, but these machines are traditionally considered less reliable.
To understand where we can see the drawings by helicopter when they first appear. Product helicopter aircraft piston engine and installed on their helicopters. However, these engines are not powerful enough to levitate. For more power, the motor operates at a higher speed and thus the reliability immediately. Once the Lycoming O-360 lower TBT was built from 2000 hours to 1600 hours for RC helicopter brushless motor engines. This piston engine powered reputation for reliability.
In 1979, Frank Robinson R22 took tandem. His idea was a lot of helicopter descends to reduce the energy required. For example, the ring system T-bar and weighs less easily than traditional dual control. Then he took the Lycoming O-320 engine reliability and reduces the speed and capacity of 160-124 maximum exploration 2700-2652. So Lycoming TBO 2000 hours was approved for fixed wing. He did the same thing with the R44, Lycoming O-540 engine. The engine was reliable Lycoming MSW increased to 2,200 hours for the two helicopters fuselages of this plant is installed in the engine itself MSW in planes. Accident data NTSB ensures the reliability of energy reduction achieved several engines.
Even with significantly improved reliability, piston engines suffer from low power to weight. Thus, for helicopters over 2500 pounds gross weight, the direction of the turbine. It is compact, lightweight and has a simple design, offering exceptional reliability. Perhaps the most important feature is the high power to weight ratio. This makes Turbomeca is the only option for large electronic speed controller design and two engines. However, the disadvantage of these engines is to provide the high costs of operation and maintenance.

Remote Control Helicopter maximum performance departures



PTO is used to climb the steep slope to remove obstacles to the flight path. View this maneuver successfully, you need a driver, wind speed, temperature, height, weight, center of gravity and other factors, the performance of the RC Helicopter Parts.
The traditional method is as follows: When the power pointing to verify that you have enough energy to bring the helicopter to the wind and started taking light helicopter in his skates. Pause to neutralize all aircraft movements. Slowly increase the cyclic and collective position of the Earth in relation to a break of 40 knots. As a rule, the same configuration as the skids of the Buy Remote Control Helicopter. Then gradually increasing the power available policy has been reached. This has great collective movement of a significant increase in the movement stroke. Cyclic as needed to control the movement toward the desired flight path angle, and then increases during the maneuver. Keep rotor at high speed, and not reduce, and may be out of the bus to get it. Follow these records until the helicopter obstacle, then reduce the height of a normal attitude and performance. As with any maneuver maximum performance, the effect of the methods, the actual results. Inputs allow a coordinated and precise control of the helicopter for maximum performance. Furthermore, the helicopter will likely be in the shaded area at the time of curve, in which the main low power to windmilling in case of engine failure. Mode reduces the time of exposure to the helicopter in a low power state.
But other riders I spoke to prefer a slightly different technique. Instead of using the maximum power, use the minimum power required to drive safely and remove the obstacle. The theory is that in the event of engine failure, less energy, a pilot with the rotor speed can be set in autorotation. It can also increase the possibility of significant damage at a critical time. I'd be interested to hear the comments of the two theories.

Instrument flying Hobbywing Pentium 40A ESC Speed Controller


When I received the bill of the ICC in 1981, the helicopter is a very rare instrument. In fact, at that time, few companies have been invited to work as a professional helicopter pilot. Today is very different. Instruments needed for most jobs, and all training programs include assessment. In addition, each pilot will start his coaching career (like most people) CFII.
Flight instruments at each airport for 30 years. Now with GPS approaches may be cheaper almost everywhere, so that IFR helicopter operations under more reasonable. However, there are restrictions on helicopters. The first interval.Helicopters typically takes about three hours of fuel. Have a great time, can be very difficult to get to your destination,brushless motor speed controller you will find a qualified alternative fuel must reserve in advance.
Due to the unique characteristics of the helicopter, CFR help limit the scope. Helicopters are to provide fuel for 30 minutes and not more than 45 minutes for airplanes (CFR 91 167 (3)) in relationship. E 'is used for a long time to determine if an alternate airfields required 91 CFR 167 (b) (2) provides a minimum below helicopters.
(I) helicopters for other aircraft. At least 1 hour before and one hour after the estimated time of arrival, the ceiling will be at least 2,000 feet above the airport elevation and the visibility will be at least 3 km from the statute.
(II) for helicopters. Estimated time of arrival and for 1 hour after the estimated time of arrival, the ceiling will be at least 1,000 feet above the airport elevation, or at least 400 feet above the highest minimum down approach, which is more visible state and at least 2 miles.
In 91 CFR 169 (c) (1) alternate airport IFR minimum time is also different.
(I), for aircraft other than helicopters: alternative minimum specified in the procedure, or if not specified the following standard approach minima:
(A) In case the process is the approach. 600 foot ceiling and 2 miles visibility status.
(B) For the procedure for non-precision approach. 800-foot ceiling and 2 miles visibility status.
(II) for helicopters flew ceiling 200 feet above the minimum approach, and the visibility is at least 1 km law, but not less than the minimum visibility for the approach of the flight.
IFR helicopter regulatory system helped save more.

    Cómo producir una Jammer de teléfono celular de las manos?

    Usted debe hacer que el teléfono celular jammer paso a paso.La emisión del teléfono celular funciona con frecuencia ya que la mayoría de teléfonos móviles se utilizan para operar. Así que el VCO seleccionado es un oscilador de barrido, que es muy eficaz, pero puede ser difícil de construir para los principiantes sin agradable RF-prueba del equipo.Como una fuente de ruido se puede usar oscilador de reloj de 45MHz, que está impulsando puerto oscilador local situado en un mezclador de mini-circuito.cell phone jammer También hay una red de adaptación de impedancia para la señal de oscilador local para pasar a través de él. Se utiliza para igualar las impedancias de la oscilador de reloj y el puerto de la mezcladora.Entrada de RF (que es este puerto de la mezcladora) conectado a la primera antena 800 MHz teléfono celular, y la salida de RF se envía al amplificador mini-circuito. Este amplificador aumenta la potencia de salida de 15-16dBm. La señal amplificada luego se envía a la antena del teléfono celular segundos.
    2 ¿Cómo funciona? Todos los teléfonos celulares que utilizan GSM800 tienen sus frecuencias transmitidas y recibidas siempre separados por 45MHz. Así que cuando el teléfono móvil intenta llamar está bloqueado por su propia señal regresando a él! ¿No es genial? Cuando el teléfono le molesta blabber - Convierte tu jammer sobre malhechor y que escuchará propia voz en su teléfono celular.Ah, por cierto, también puede utilizar este jammer señal celular para bloquear cualquier sistema de rastreo basados ​​en células que utilizan el GPS para rastrear y registrar los movimientos de tu coche.
