While some brushless motor speed controller are designed for speed



While some brushless motor speed controller are designed for speed, the other son built the place simply rising too. Perhaps the best example is the S64 Erickson Aircrane. S-64 was first flew as a helicopter pilot valve station on the back, the pilot realized that the control of the aircraft during loading and complete accuracy can build. The rc helicopter blades for sale was certified in 1969 and produces only original parts for Sikorsky S-64A Skycrane Aircraft. In 1992, Ericsson acquired certificate Sikorsky S-64E and S-64F model aircraft and the name was changed to S-64 Aircrane. Today, Erickson and operates a fleet of 18 Aircranes worldwide.

Aircrane rotor consists of a main rotor UN seismic fully articulated main rotor blades and tail four. S-64E is powered by two Pratt & Whitney scored generation combined maximum takeoff weight of 9,000 hp, so that S-64E. Ability to lift external 20,000 pounds (9.072 kg) at sea level, representing the string S-64F ENHANCED cell model without a rotor and two Pratt & Whitney 9600 hp S, the external load 64F 25,000 pounds (11.340 kg ) at sea level

Starting in civilian mission focused logging Aircrane and power lines, but is used in such areas mentioned in many construction costs. For example, installation of elevators, air conditioning and lightweight steel construction.

RECYCLING replacing most commonly involved and the Statue of Liberty, which tops the dome of the Capitol in Washington must control Aircrane Levanto pedestal of the statue, May 9, 1993, and after putting in the necessary restructuring, a new October 23 1993 other important projects was the construction of the C-CN Tower in Toronto, Canada. In 1975, the post office and helped a ton of steel profiles Aircrane seven, including antenna systems and weather forecasts. At the time, most of which were the highest in the world, independent structure, one at 1850 meters above sea level

In 1992, water bomber fire Erickson CREO Extinction of the United Nations in 2650-gallon tank, water, foam mix, burning or floral spray. Two tubes of attack does not last more than 45 seconds to complete each of the salt and fresh water source at least 18 inches deep. In 1997, the FAA certified Water Canyon tourism investment monitor horizontal structural fire in urban areas. Weapon used in hydraulic power from the aircraft, the concentrated stream of water or a mixture of foam control speeds up to 150 m pitch to 300 liters per minute. The rc helicopter parts is now a valuable tool in fighting fires in California and contradictory world over.
