Robinson R-22 Beta
The Robinson R22 has undisputedly been the
world's most popular light helicopter since its
introduction in the late 1970s. The R22 has a
very low inertia rotor system and the control
inputs are operated directly by push rods with
no hydraulic assistance. Thus, the flight
controls are very sensitive and require a light
touch to avoid over correcting. A student that
masters an R22 generally does not have a problem
transitioning to a heavier helicopter.
The
R-22 is a single-engine helicopter with a
semi-rigid two-bladed main rotor and a
two-bladed tail rotor. The main rotor provides a
teetering hinge and two coning hinges. The tail
rotor provides only a teetering hinge.
Instead of a floor-mounted cyclic stick between
the pilot's knees, the R22 uses a unique
teetering "T-Bar" control connected to a stick
that emerges from the console between the seats.
The
R22 uses a horizontally mounted
98kW (131hp) takeoff rated Textron Lycoming
O320B2C.,
air-cooled, normally-aspirated,
carburetor-equipped piston engine, fueled with
100LL grade aviation gasoline.

Robinson R-44 Astro
The
Robinson R44 is a small American light,
four-seat, piston-driven civilian helicopter
produced by the Robinson Helicopter Company
since 1992.
The
R-44 is a single-engine helicopter with a
semi-rigid two-bladed main rotor and a
two-bladed tail rotor and a skid landing gear.
It has an enclosed cabin with two rows of
side-by-side seating for a pilot and three
passengers.
While resembling the company's earlier Robinson
R22, the R44 is larger and faster than its
predecessor. It also features boosted flight
controls, a feature not found on the R22. The
Astro model incorporates electric cyclic trim.
The
R44 uses a
(260hp) Textron Lycoming O-540 flat six (derated
to 165kW (225hp) for takeoff) drives two blade
main and tail rotors, while other features
include an electronic throttle governor, rotor
brake and automatic clutch.
