Read before assembly
1. Before assembly, read the instruction manual thoroughly familiarizing yourself with
the model and assembly procedures.
2. Check the contents of the box and make sure there is no missing part and all parts
are in good shape. After the packaging has been opened and parts have been used,
parts cannot be exchanged or returned.

An R/C Helicopter is not a toy.
Despite its small size, it can cause serious injury as its rotor blades
rotate at very high speed. This helicopter is a complex flying machine.
Therefore, it must be assembled with care by a responsible person.
Since the manufacturer and its agents have no control over the proper
assembly and operation of the model, no responsibility or liability can
be assumed for its use.
Warning!

Safety Guidelines for the R/C Helicopter
1. Beginners should get guidance and supervision from experienced flyers.
2. Fly only at approved airfields.
Do not fly at school, residential area or near roads, railways and power lines.
3. Make sure there are no other pilots flying with the same radio frequency as yours.
Interference can be very dangerous to all.
4. Keep the helicopter at least 5~10m away from the flyer for safety.
5. Do not fly the helicopter behind the flyer himself.
6. Never fly near or above other flyers, spectators or cars.
7. In case of emergency, priority should be given to the safety of other flyers and spectators.
2-1. Before a flight
1. Make sure batteries in the helicopter and the transmitter to be fully charged before flying.
2. Do a range check of the radio before the first flight. The radio should work at least
20 meters away from the helicopter with the transmitter antenna collapsed.
3. Inspect the helicopter thoroughly so that there are no missing or loose bolts.
Important checking points: linkages, rotor blades, motor, gears.
4. If there is too much slops or breakage in the linkages, replace it with a new one.
The linkages should not be too loose or too tight and they just fit snugly.
5. Carefully check that the rotor blades are not damaged or cracked, especially around
the hole of the blade holder. Check that the rotor blade is safely fastened.
6. Make sure the motor is fastened securely to the mount as it produces high degree
of vibration.
7. Check that the servos operate smoothly and properly.
Their malfunctioning may cause a loss of control that will result dangerous situation.
8. Be sure to keep the following sequences to turn on or off the power:
① When you start flying, turn on the transmitter first and then the heli.
② After flying, turn off the heli first and then the transmitter.

2-2. During the flight
1. We strongly recommend you to spend time in practicing the helicopter simulation program
before you fly the real model.
This will get you confidence and will significantly reduce the cost of repair.
Keep practicing the simulation program and that will accelerate your learning curve.
2. If you face any problem during the flight, force the heli down straight away.
3. If there is other helis in the airfield, you are advised not to fly at the same time.
But if you really want to, make sure to check the radio frequencies to prevent interfering.
4. In case there are people or animals in the airfield, a flyer should pay special attention to
these objects coming to him or the helicopter as the flyer usually occupy himself in the
flying only.
2-3. After the flight
1. Conduct a through inspection on the helicopter to insure no parts have come loose
or become damaged during the flight.
2. Check the temperature of motor and battery.
If they are too hot to touch, something goes wrong.
In this case, you should find the problem and fix it before the next flying.
3. Disconnect the battery from the speed controller.
If you leave the battery connected overnight, this will seriously damage the battery.
4. When the helicopter has crashed, inspect, in particular, main rotors, tail rotors, main mast,
tail shaft, the flybar, and the feathering shaft.
If any part is damaged, it must be replaced with a new part.
Do not try to repair damaged or broken parts with glue.
The parts in the helicopter are under high stress due to vibration.
If parts fail during the flight, this will lead to a loss of control that is highly dangerous.

Pitch and Throttle settings
4-1. Pitch Range setting
ⓐ Check that no data has been input into the pitch curve function of the transmitter.
If any data has been input, delete it.
ⓑ Adjust the length of the pitch linkage rods so that the main blade pitch is 0˚ when
the transmitter throttle stick is in the mid position.
ⓒ Check that the full stroke is set to approximattely 22˚.
For example, if the low pitch is set to -11˚ and the high pitch is set to 11˚, than,
11˚-(-11˚)=22˚.
If you don't get 22˚ for the full stroke, use the transmitter's rudder angle
adjustment function for swash mode, and input data so that it becomes 22˚.

Steps should be taken before flying
① Extend the transmitter antenna.
② Put the throttle stick of the transmitter at low position and then turn on the transmitter.
③ Put the hold key at on position. (This will prevent the main rotor from rotating abruptly
in case that you put the throttle stick at high position inadvertantly).
④ Connect the battery to the esc.
⑤ Wait until the ESC sets up itself with buzzing sound.
⑥ Move the elevator and ailron sticks of the transmitter and check up the swash movement.
⑦ If everything goes all right, turn the hold key off.
⑧ Start the main rotor by moving the throttle stick up slowly.
※ Refer to the transmitter manual for setting up hold key.
