The only setting up needed is the adjustment of your transmitter's settings, where required. Although not strictly a beginner's model, the Snelflight Chinook is surprisingly rugged and easy to fly. However we strongly suggest that you take the time to read this manual carefully before your first flight, as the aircraft behaves a little differently from other model helicopters.

Since the transmitter connects to the model by wire, frequency and transmission type (AM or FM) do not matter. The signal lead included with the model is suitable for JR transmitters only. Please see your dealer or contact Snelflight to obtain leads for the other types. HANDLING THE MODEL...
ON, but the crystal should be removed to prevent radio transmission. b) Signal Mode Selection: The Chinook requires PPM signalling, so if your transmitter offers PCM as well, it must be switched to PPM. Most inexpensive non-computer radios are PPM only, so this setting is not necessary.
PREPARING FOR FLIGHT Before flying the model, you should carry out the following procedure: a) Stand the helicopter on the floor, facing away from you. Feed the command line rearwards, ensuring that it doesn't catch on the wheel axles. b) Connect the power adapter to the wall, and plug its 2.1mm output jack into the matching socket at the bottom end of the command line.
PRINCIPLES OF OPERATION The Chinook generates the lift necessary for flight by means of the six small, rapidly spinning rotor-tip propellers. The rotors themselves do not provide any lift. The outboard positioning of the motors gives each rotor a...

stability to the aircraft. At the same time, the rapid movement of the motors through the air keeps them comparatively cool during operation. Cyclic control is provided by varying the speeds of the motors as they move around their circular path. For example, to provide a left-hand roll force, the motors slow down as they enter the left-hand semicircle, and speed up as they enter the right hand semicircle.
MAINTENANCE A. DISASSEMBLY 1) Remove the rotors. To remove a rotor: a) Unplug the power cord from the command line. b) Pull the black plastic dome off the shaft. c) Carefully lift the rotor off, taking care not to bend the brushes on the underside of the hub.

(spin the rotor by hand and listen). D. AIRCRAFT TRIM When the control signal is connected to the Chinook, the aircraft automatically configures itself to suit the particular transmitter being used. This process includes precise adjustment of electrical control trims, making further trimming of the aircraft unnecessary most of the time.

The weight needed will generally be under two grams, and a small ball of Blu-Tack is ideal. A new Chinook will often have this correction applied during factory testing:- the weight will be just inside the body at either the front or rear end of the underbelly opening.
