Operate the helicopter in open areas with no people nearby.
Follow your countries air regulation rules.
You may need to join a local club and become a member before you can y the model.
Do NOT operate the helicopter in the following places and situations (or else you risk
severe accidents)
In places where children gather or people pass through in residential areas and parks,
indoors and in limited space in windy weather or when there is rain, snow, fog or other
precipitation. If you do not observe these instructions you may be held liable for personal
injury or property damage!
Always check the R/C system prior to operating your helicopter.
Keep in mind that other people around you might also be operating a R/C model. Ne-
ver use a frequency which someone else is using at the same time. Radio signals will be
mixed and you will lose control of your model.If the model shows irregular behavior, bring
the model to a halt immediately and disconnect the batteries. Investigate the reason and
x the problem. Do not operate the model again as long as the problem is not solved, as
this may lead to further trouble and unforeseen accidents.In order to prevent accidents
and personal injury, be sure to observe the following:Before ying the helicopter, ensure
that all screws are tightened. A single loose screw may cause a major accident.
Replace all broken or defective parts with new ones, as damaged parts lead to crashes.
Never approach a spinning rotor. Keep at least 5 meters/yards away from a spinning rotor
blades.Do not touch the motor immediately after use. It may be hot enough to cause
burns. Perform all necessary maintenance.
PRIOR TO ADJUSTING AND OPERATING YOUR MODEL, OBSERVE THE FOLLOWING
Operate the helicopter only outdoors and out of people’s reach as the main rotor opera-
tes at high rpm!
Note that a badly assembled or improperly adjusted helicopter is a safety hazard!
In the beginning, novice R/C helicopter pilots should always be assisted by an expe-
rienced pilot.
SAFETY FIRST! ALWAYS.

About Tronhelicopters
Designed, engineered and manufactured by YINTECH and Tronhelicopters Switzerland.
Tronhelicopter’s team was built in 2019. Including professional RC Helicopter Pilot and RC
FPV Drone World Champion from 2017 Dario Neuenschwander, we partnered with YIN-
TECH, to provide high-quality manufacturing thanks to over 18 years experience within
the helicopter industry.
Partnered together, an idea was born to release a helicopter that satised the market
needs. Lightweight, strong, simple assembly, ease of maintenance, high quality, a wide
ight envelope with precision and responsiveness, all while delivering unique and sporty
robotic aesthetics.
After over a year of testing, the Tron 5.5 was found to deliver superior performance while
utilizing 550mm class rotor blades. Any pilots will nd not only a great ight experience
but also plenty of neat features of the model.
Pilots can power the Tron 5.5 with a wide variety of motors and battery setups, ranging
from 4020, and 4025 motors, as well as 6s, 8s, and even 12s power systems.
Low head speed and high head speed provide pilots the exibility they want in a helicop-
ter, to meet the performance they want.
No matter your needs as a pilot, the Tron 5.5 will meet them all.
