Check to make sure there is no radio interference before operating a model helicopter. Make sure the transmitter and receiver batteries are fully charged before operation. Model helicopter main and tail rotors operate at high rpm, therefore make sure nothing can come into contact with the rotors during flight. The servos must operate properly with the transmitter antenna collapsed and at 20 meters away. Make sure the transmitter and receiver are turned on before starting the engine. Do not touch the engine or muffler immediately after the engine was run, because they will be extremely hot. Warning (Items to watch out after flight) Inspect the model helicopter thoroughly to make sure nothing is loosen or damaged. Lubricate every moving part with oil to ensure a smooth operation in the future. Warning (For Storage) Keep the model in a cool, dry place. Add some engine after-run oil through the carburetor, then crank the engine by an electric starter. Please replace any damaged parts if they are discovered during maintenance. 43 Preflight Checklist and Starting Procedure Control system check. (1) The flybar and control paddles must tilt in the proper direction and smoothly through the whole range. Once you can keep the model at one place, then it is time to slowly increase the height a few centimeters (inches) in each flight. Soon, you will be able to hover the helicopter confidently at few feet high. Beginners should always practice hovering close to the ground because in an emergency panic, throttle and collective can be reduced rapidly without causing a large drop or damage to the model. If the model was hovering at beyond one meter(3 feet) altitude, then always descend slowly. A panic drop can damage the helicopter. (5) Always stand behind the model helicopter when learning how to hover because then you can watch the nose of the helicopter, and a left tail rotor command will yaw the helicopter nose to the left, and a right command will yaw to the right. Similarly, a left cyclic command will cause the helicopter to translate left. After you can comfortably hover the model at one meter high without drifting, then start practice hovering while standing to either side of the model. Eventually, you need to be comfortable at hovering the model from any orientation, including with the helicopter nose pointing at you, this is challenging because all control directions are seem backward. (6) Once you can confidently hover a model helicopter at any altitude and at any orientation, then congratulate yourself because you have mastered 80% of the fundamental control movements of a helicopter. 48 Forward Flight Training After mastering hovering flight: (1) Start practicing moving the helicopter laterally to the left or right slowly from a 1. 5 meter (60 inches) high hover. This is the beginning exercise of translational flight. hovering at 1-1. 5 meter (2) After a few hours of practicing step (1) and you are comfortable with translational movement, start using some tail rotor control so the helicopter nose will point slightly to the left or right as you fly it to the left or right. Please visualize these movements in your mind. 49 After Flight Checklist The model helicopter should be thoroughly inspected after each flying session. (1) Check every screw and bolt to make sure none has loosened due to vibration. [. . . ] (3) Does the throttle control arm move properly and in the correct direction according to your transmitter command?There are different types of glow plugs on the market for different types of fuel and operating conditions. Seek the advice of experienced fliers and also experiment with different types of glow plugs until you find the one that suits your operating condition the best. (1) Check the main rotor blade pitch angle, they should be set at 5. 5 to 6 degrees when the transmitter throttle/collective stick is at the center position. [. . . ]
