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.
Moquito XE Helicopter flying (PART 2) - FullFlap.TV 22ndJuly09

Today: 22nd July 09
Last week we got the details. For the price of one Robinson R22 you could
buy nearly 5 of these and pay for all the training. But does it really fly
or is it just a model?

Hiller Rotorcycle, Ultralight Personal Helicopter 1957
Small enough personal helicopter when folded to carry in a pod under an
aircraft's wing or on the luggage rack of your car, this contraption
becomes a full sized helicopter in a matter of minutes - capable of taking
off from your backyard and flying anywhere in the San Francisco Bay Area on
a single tank of gas.
In1954 Hiller Helicopters was selected by the Navy's Bureau of Aeronautics
to build a one man, foldable, self-rescue and observation helicopter. The
Hiller Model 1033 was designated by the military as the XROE-1
"Rotorcycle." Two prototypes were built at the Hiller Helicopter Plant in
Palo Alto, California. The helicopter has the Hiller Rotormatic control
paddles with a conventional tail rotor. Power was supplied from a Nelson
H-59, two cycle, 40 hp, four cylinder opposed air cooled engine through a
centrifugal clutch. The prototype Rotorcycle first flew on January 10,

GEN H-4 vol4
Demo flight at Matsumoto airport of the GEN H-4, the World's smallest
manned helicopter, developed by GEN Corporation.
General information about GEN Corporation and the GEN H-4 can be found at:
Current price for a (gasoline) GEN H-4 prototype is JPY 7,500,000.00 or
about USD 100,000.00 due to small production capacity.
People often ask, "What happens when that little engine quits?" At 500 feet
I shut the engine off. See what happens.
Homebuilt Helicopter from beginning to end
A compressed compilation of the 2+ hours (off the ground) learning to hover
and tweaking the machine.
Realizing the dream was a huge sense of achievement for me, and I can
understand how our Pioneers were so focused on their goals.
SUPER FAST Piasecki X 49A Helicopter for US Military
Helicopter The Piasecki X-49 is a four-bladed, twin-engined, experimental
compound helicopter under development by Piasecki Aircraft. The X-49A is
based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes
Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and
includes the addition of lifting wings. The concept of the experimental
program is to apply the VTDP technology to a production military helicopter
to determine any benefit gained through increases in performance or useful
"SpeedHawk" is a concept aircraft based on applying X-49A compounding
concepts to a production UH-60 Black Hawk offering better performance,
range, and increases in useful load. The "SpeedHawk" aircraft includes an
SPU (third engine), high forward-swept wing concept, a 45 inch cabin
extending fuselage "plug", and several other drag reducing and
performance-oriented improvements, including a rotorhead fairing, landing
gear streamlining, and a fly-by-wire flight control system.
The U.S. Navy-sponsored project worth US$26.1 million consists of a
Sikorsky YSH-60F helicopter modified by Piasecki as a testbed to validate
the "Vectored Thrust Ducted Propeller" (VTDP) system. One YSH-60F was
converted to test the feasibility of VTDP under an advanced technology
demonstration program. The YSH-60F is powered by two General Electric
The demonstration contract was awarded on by the Naval Air Systems Command
to Piasecki Aircraft. Piasecki installed a lifting wing with flaperons and
a vectored-thrust ducted propeller (VTDP) to a U.S. Navy Sikorsky
The compound helicopter technology added to the YSH-60F was first
demonstrated in trials of the Piasecki 16H-1 and 16H-1A in the early 1960s,
when the helicopters were flown at speeds up to 225 mph (360 km/h). The
success of the Pathfinder inspired others to experiment with compounding,
resulting in programs such as the AH-56 Cheyenne.
In May 2003, the YSH-60F/VTDP demonstrator was redesignated the X-49A'.
During 2004, the X-49A VTDP program was transitioned from the US Navy to
the US Army.
Piasecki planned to use the vectored-thrust ducted propeller design of the
X-49 for their entry in the Future Vertical Lift program, but were not
chosen to take part in the Joint Multi-Role Technology Demonstrator
The X-49A flight demonstrator is being developed with funding from the US
Army's Aviation Applied Technology Directorate to demonstrate the ability
to increase the speed of existing helicopters to 200 kt (360 km/h) or
more. The flight demonstrator has been updated with a lifting wing taken
from an Aerostar FJ-100 business jet. A ring tail has been added and the
helicopter drive train modified to accommodate VTDP. Piasecki conducted
integrated tests of the modified drive train at the Navy's helicopter
transmission test facility. The wings are intended to produce lift to
offload the rotor so the rotor can be slowed down and produce less drag,
allowing for higher speed.
The cockpit controls are modified with the addition of a manual prop pitch
override on the collective for the ring tail. This is the only visible
change to the aircraft's existing mechanical controls in the cockpit. The
other controls needed to operate the compound helicopter's systems are
integrated into the aircraft's existing mechanical controls to reduce pilot
workload. The weight added to the X-49A demonstrator aircraft is estimated
at about 1,600 lb (725 kg) due to the requirement to not
modify the existing mechanical control system.
The X-49A made its first flight on June 29, 2007 for 15 minutes at
Boeing's New Castle County (KILG) flight test center. This flight
included hovering, pedal turns, and slow forwards and sideways flight using
the VTDP for anti-torque, directional and trim control. The X-49A has
completed its initial testing phase, and is continuing with further testing
of the technology. Since then, it has flown over 80 flight
events with more than 80 total hours logged.
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 forward, backward, 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 Ponton d'Amécourt in 1861, which originates from the
Greek helix/helik- (ἕλιξ) "twisted, curved" and pteron
(πτερόν) "wing". English-language nicknames for helicopter
include "chopper", "helo", "heli" and "whirlybird".
Gyrocopter High Wind Takeoffs at El Mirage
Here's a video clip from around 1995 of Ed Neleski and Ken Brock flying on
a very windy day at El Mirage, California. This clip was from an episode of
Dan Lesley's Rotor/Wing Sports TV show. For more info on gyros see

First9Tries to fly a Mosquito Ultralight Helicopter, GB103
After 10 hours of dual training in an R22, I try my new Ultralight
Helicopter. The last clip (#9) was almost a DR (Dynamic Rollover). I did
this 2 years ago and did not understand the danger or causes of DR, or how
to avoid DR, or what to do when DR is happening. So lucky to instinctively
lower the collective, ha, - wait, not luck, FEAR! Respect the danger.
