NOTE FOR AS SEMBLY
R/C helicopters, including the AGILE 5.5 are not toys. R/C helicopters utilize various high-tech products and technologies to provide
superior performance. Improper use of this product can result in serious injury or even death. Please read this manual carefully
before using and make sure to be conscious of your own personal safety and the safety of others and your environment when
operating all AGILE products. Agile 5.5, KDS Model, their affiliates and authorized distributors are not responsible for personal
injuries to the operators and others, and property damages that could occur from the assembly, maintenance or your use/misuse of
this product. Always respect the rules provided by your local remote control aircraft organization.
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.
OBTAIN TH E ASSIS TANCE OF A N EX PERIE NCED PI LOT
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
During the operation of the helicopter, the main rotor will be spinning at a high rate of speed. The
blades are capable of inflicting serious bodily injury and damage the environment. Be conscious of
your actions, and careful to keep your face, eyes, hands, and loose clothing away from the blades.
Always fly the model a safe distance from yourself and others, as well as surrounding objects. Never
take your eyes off the model or leave it unattended while it is turned on. lmmediately turn off the
model and transmitter when you have landed the model.

PROPE R OPERAT IO N
Please use the replacement of parts on the manual to ensure the safety of instructors. This product is
for R/C model, so do not use for other purpose.
SAFE O PE RATION
Operate this unit within your ability. Do not fly under tired condition or improper operation, which
may cause danger.
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.
