The Original:
The Robinson R22 is a two-seater light weight helicopter manufactured since the beginning of the seventies by the
American company "Robinson Helicopter". The basic idea was to build a simple, light weight and low cost helicopter for
training, surveillance and private purposes. The low maintenance costs are the reason why this helicopter is enjoying
such a wide popularity.
The R22 is powered by a conventional piston engine manufactured by Lycoming. The advantage of the piston engine
compared with a turbine engine is the substantially lower price and the favorable replacement part and maintenance
cost. The installation behind the cabin however required a forced cooling system using a fan. The R22 is an extremely
maneuverable helicopter and can go from full speed into slow or hover flight within a shortest distance.

To enable you to start right away, the following items must be checked off and the following programming steps must be
carried out.
- In the set with transmitter the helicopter is programmed in "Mode 2", i.e. pitch/throttle and tail rotor are operated with
the left control stick, forward pitch and roll function with the right control stick. Please insert 8 AA batteries into the
transmitter battery compartment before operation. For the set without transmitter and changes in functions please read
the chapter "Channel Assignment" on the following page.
- Before the first flight you need to check and adjust the blade tracking. Read the chapter "Blade Tracking".
- Before operating the helicopter always make a function check, i.e. viewing from behind the helicopter the swashplate
has to move into the same directions as the control stick. For example for roll to the right the swashplate will have to
move down to the right (see also chapter "Control Functions"). If one or more functions are moving wrong you may
reverse them on the reverse switch on your transmitter. Definitely unplug the flight battery before reversing functions.
- Secure the flight battery (not included in set contents) inside the battery compartment by using the hook and loop strap
to avoid that it moves during the flight. Always use fully charged batteries only. The GigaTronic has been set up at the
factory for use of Lithium-Polymer batteries.
- Switch on the transmitter and check that the pitch/throttle function is in idle position. Now connect the flight battery to
the helicopter.
- Before take off you should adjust the tail rotor: move the tail function stick all the way to the right and hold it until you
will receive a confirmation from the tail rotor (rotor makes one revolution). Now the gyro is dialed in. Tip: If the tail rotor
is drifting due to external influences, this procedure can be repeated anytime (on the ground only!).
- Slowly increase throttle/pitch now. Due to the integrated soft start the rotor will slowly accelerate to its operational rotor
speed. The tail rotor will start at the first 10% of the stick throw. The gyro has been set to Heading-Lock-Mode at the factory.
It is normal for the tail rotor to start up only once the tail changes its position on the ground or after take off.
- We strongly recommend that beginners carefully read the chapter "First Flight Maneuvers", in order to learn about flying
faster and more safely.
- After flying keep in mind that the flight battery of the helicopter must be unplugged first, and the transmitter switched
off afterwards. When transporting the helicopter always remove the flight battery to avoid any damage to the fuselage.
