[. . . ] Operating a model helicopter for extended time can cause fatigue. 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. Pump out the remaining fuel from the fuel tank. 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. Avoid storage under direct sun light or near heat. Add some engine after-run oil through the carburetor, then crank the engine by an electric starter. This help to prevent the engine bearings from rusting. After-run oils are available from hobby shops. 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. (2) The rotor shaft and flybar must be straight and not damaged. (3) The swashplate must remain clean and tilts freely. But with repeated practice close to the ground you will develop a feel for the controls. It is recommended to let a more experienced model helicopter pilot trim out your new model before you attempt to learn to hover. 47 (4) It will take a few hours of hover practice with the helicopter skids at 10 to 20 cm (4-8 inches) off the ground in order to comfortably control the model. Do not try to lift the model to more than 10 to 20 cm(4-8 inches) in the beginning because then the model may tip over readily when the beginner panics and an incorrect command is given. 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. [. . . ] (2) Does the engine throttle arm move properly?The carburetor opening should be fully open when the transmitter throttle/collective stick is moved up. The carburetor opening should be nearly closed when the transmitter throttle/collective stick is moved down. And the opening should be completely closed when the transmitter throttle/collective stick is moved down and the throttle trim is also moved down. [. . . ]
