RC BIG SCALE Helicopter CH53 Heer RC
Im Alter von nur 59 Jahren verlor die Modell Szene ein Urgestein des
Hubschraubersports. Heinz Hoffmann * 15.09.1954 ist am 06.06.2014
Wir trauern um einen Freund und Fliegerkollegen der mit seiner Ruhe und
seinem Sachverstand vielen Jungpiloten ein Vorbild war und mit diesem Film
auch immer bleiben wird.
Dieses Video war das erste das ich gedreht habe und ist der Grund weshalb
der Modellsport, das Fliegen zu meinem Hobby wurde. Vielen Dank lieber
Heinz. Wir vermissen Dich sehr !
Ruhe in Frieden.
Unsere Gedanken sind bei seiner Familie.
WORLD CHAMPION RC Helicopter pilot Demonstrates his Awesome Skills
Radio-controlled helicopters (also RC helicopters) are model aircraft which
are distinct from RC airplanes because of the differences in construction,
aerodynamics, and flight training. Several basic designs of RC helicopters
exist, of which some (such as those with collective

pitch, meaning blades which rotate on their longitudinal axis to vary or
reverse lift so the pitch can be altered and can therefore change the angle
of attack) are more maneuverable than others. The more maneuverable designs
are often harder to fly, but benefit from greater aerobatic capabilities.
Flight controls allow pilots to control the collective and throttle
(usually linked together), the cyclic controls (pitch and roll), and the
tail rotor (yaw). Controlling these in unison enables the helicopter to
perform most of the same maneuvres as full-sized
helicopters, such as hovering and backwards flight, and many that
full-sized helicopters cannot, such as inverted flight (where collective
pitch control provides negative blade pitch to hold heli up inverted, and
pitch/yaw controls must be reversed by pilot).
The various helicopter controls are effected by means of small servo
motors, commonly known as servos. A piezoelectric gyroscope is typically
used on the tail rotor (yaw) control to counter wind- and
torque-reaction-induced tail movement. This "gyro" does not itself apply a
mechanical force, but electronically adjusts the control signal to the tail
The engines typically used to be methanol-powered two-stroke motors, but
electric brushless motors combined with a high-performance lithium polymer
battery (or lipo) are now more common and provide improved efficiency,
performance and lifespan compared to brushed motors, while decreasing
prices bring them within reach of hobbyists. Gasoline and jet turbine
engines are also used.
A helicopter is a type of rotorcraft in which lift and thrust are supplied
by rotors. This allows the helicopter to take off and land vertically, to
hover, and to fly forwards, backwards, and laterally. These attributes
allow helicopters to be used in congested or isolated areas where
fixed-wing aircraft would usually not be able to take off or land. The
capability to hover efficiently for extended periods of time allows a
helicopter to accomplish tasks that fixed-wing aircraft and other forms of
vertical takeoff and landing aircraft cannot perform.
The word helicopter is adapted from the French language hélicoptère,
coined by Gustave de Ponton d'Amecourt in 1861, which originates from the
Greek helix/helik- (ἕλιξ) = "twisted, curved" and pteron
(πτερόν) = "wing". Nicknames used for helicopters include
chopper, helo or whirlybird.
Helicopters were developed and built during the first half-century of
flight, with the Focke-Wulf Fw 61 being the first operational helicopter in
1936. Some helicopters reached limited production, but it was not until
1942 that a helicopter designed by Igor Sikorsky reached full-scale
production, with 131 aircraft built. Though most earlier designs used
more than one main rotor, it is the single main rotor with anti-torque tail
rotor configuration that has become the most common helicopter
configuration. Tandem rotor helicopters are also in widespread use due to
their greater payload capacity. Quadrotor helicopters and other types of
multicopter have been developed for specialized applications.
Red Bull Helicopter does back flips!
Yes, it does back flips. It is a Eurocopter BO-105 CBS 4 Twin engine
helicopter. Stock model with a Rigid Rotor system, the fixed rotor is why
it can do aerobatics.
