The following manual provide important instructions to correctly assemble the model. It is structured in a logical way, based on the work
done in previous step. If you change the order, it may result in additional or unnecessary steps. So we suggest you to read this user manual
very carefully to understand correctly the assembly procedure. Failure to do so may not only downgrade performances but also increase
the risk of danger. Apply thread lock as indicated, allow the threadlock to cure before mounting parts. It is recommended to use threadlock
on each bolt or screw that are engaged with metal parts.
LOCATE A N AP PROP RIATE LOC ATI ON
R/C helicopters fly at high speed, thus posing a certain degree of potential danger. Choose an
appropriate flying site consisting of flat, smooth ground, a clear open field, or a large open room, such
as gymnasium or warehouse without obstacles. Do not fly near buildings, high voltage cables, or trees
to ensure the safety of yourself, others and your model. Do not play your model in inclement weather,
such as rain, wind, snow or darkness.

Before turning on your model and transmitter, check to make sure no one else is operating on the
same frequency. Frequency interference can cause your model, or other models to crash. The
guidance provided by an experienced pilot will be invaluable for the assembly, tuning, trimming, and
actual first flight(recommend you to practice with computer-based flight simulator).
1.INTRODUCTION
2.SAFETY NOTES

3.Safety Check Before Flying
Agile Helicopter is a Trademark of Flight Research Rc Europe , Proudly made by KDS Model Shenzhen
Page 02
Before flying, for safety reasons, make sure that no one else is operating a R/C model on the same frequency as yours.
Before flying, please check that the power of your transmitter and your helicopter are sufficient for the flight.
Before turning on the transmitter, please check that the throttle stick is in its lowest position, IDLE UP switch must be on OFF
position.
When turning off the model, please follow the power on/off procedure. Power ON: turn on the transmitter first, then turn on
helicopter power. Power OFF: turn off the helicopter power first and then turn off the transmitter. Improper operating procedure
may cause the model to be out of control, so please do make this your habit.
Before operation, check that every movement is smooth and directions are correct. Inspect servos carefully for interferences and
broken gears.
Check for missing or loose screws and nuts. See if there is any cracked and/or incomplete assembly of parts.
Check main rotor blades and rotor holders carefully. Broken and premature failures of parts might result in a dangerous situation or
crash.
Check all ball links to avoid excess play and replace as needed. Failure to do so will result in poor flight stability.
Check that the battery and power plugs are fastened. Vibrations and violent flight might loosen the plugs and so lead to out of
control.
Check for the tension of main drive belt.
PREV EN T MOIST URE
R/C models are composed of many precision electrical components. lt is critical to keep the model and
associated equipment away from moisture and other contaminants. The introduction or exposure to
water or moisture in any form can cause the model to malfunction resulting in loss of use, or a crash.
Do not operate or expose to rain or moisture.
KEEP A WAY FROM H EAT
R/C models are made up of various forms of plastic. Plastic is very susceptible to damage or
deformation due to extreme heat and cold climate. Make sure not to store the model near any source
of heat such as an oven, or heater. lt is best to store the model indoors, in a climate-controlled, room
temperature environment.
