2.3 PREVENT MOISTURE
R/C models are composed of many precision electrical components.
It is critical to keep the model and associated equipment away from condensation and
other contaminants. Exposure to water or moisture may cause the model to
malfunction resulting in loss of responsiveness, or a crash.
2.4 PROPER OPERATION
For the safety purpose, please only use hubsan’s spare parts for replacement.
2.5 ALWAYS BE AWARE OF THE ROTATING BLADES
When in operation, the main and tail rotor blades will be spinning at high speed. The
blades are capable of inflicting serious body injury and damage to the environment.
Be cautious of your actions and careful to keep your body and loose clothing away
from the blades. Never take your eyes off the model or leave it unattended while it is
turned on. Once landed, immediately turn off the model and transmitter.
2.6 AVOID FLYING ALONE
Beginners should avoid flying alone whilst learning flight skills. It is advised that an
experienced pilot be on hand for guidance.
It is recommended to practice with a computer-based flight simulator.
CAREFULLY INSPECT BEFORE REAL FLIGHT
• Before operation, please check the batteries of the transmitter and receiver are
charged enough for the flight.
• Before turning on the transmitter, please check that the throttle stick is in the
minimum position.
• Check for any missing or loose screws and nuts. Carefully check main rotor blades
and rotor holders. Broken or premature failure of parts will result in a dangerous
situation.
• Check all the ball links to avoid excess play and replace as needed. Failure to do so
will result in poor flight stability.
• Check the battery and power plug are securely fastened. Vibration and violent flight
may cause the plug to loosen resulting in loss of control.
• When turning on the unit, please follow the power on/off procedure: for Power ON-
please turn on the transmitter first, and then turn on the receiver. For Power OFF-
please turn off the receiver first and then turn off the transmitter. Improper procedure
may cause loss of control of the helicopter.
3 SAFETY CHECK BEFORE FLYING

4. Notice that the cyclic joystick is spring-loaded, you must maintain a forwards
pressure on the cyclic joystick otherwise it will return to its neutral position and your
helicopter will stop moving.
Tip-if you become confused, releasing your helicopter's controls will bring it to stop. it
will not lose height as the throttle is on a ratchet.
5. Stop you helicopter, turn it around (use rudder), and bring it back.
6. Choose a landing site. Fly your helicopter to a position that is precisely over your
chosen landing site and set your helicopter down in a smooth and precise landing.
7. Repeat this flying lesson until you become S-M-O-O-T-H-L-Y proficient and
precise.
3.5 Advanced Maneuvering
In this flying lesson you will combine cyclic joystick Pitch and Roll inputs with collective
Rudder and Throttle inputs to give more precise control to your helicopter maneuvers.
You've probably already tried combining Rudder and forward Pitch inputs. This
combination allows you to turn your helicopter, but it won’t look right. The helicopter
will remain upright. It's like watching a bicycle that's not leaning into the turn, because
air has very little grip, your helicopter will actually skid through its turn.
The solution is to make the helicopter lean-"Roll"-so that rotors help to counteract the
tendency to skid (or 'side slip').To do this, you must learn to synchronise your use of
mixed Pitch and Roll on the cyclic joystick, with mixed Rudder and Throttle on the
collective joystick
1. Begin a hover at shoulder height.
2. Push the cyclic stick Forwards to gather sufficient airspeed.
3. Begin your turn by pushing the cyclic joystick to the right (setting up the Roll) while
maintaining forward pressure.
4. As your model begins to respond to the Roll, push the collective Rudder joystick to
the right to initiate the turn.
