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.

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.
