(5) The two control paddles must be leveled and parallel to each other, and point in the correct direction. (6) Check to make sure there is no radio interfence before operating the model helicopter. (7) Make sure the transmitter and receiver are on and all controls operate properly before flight. (8) The engine carburetor must be in the idle position before starting the engine. Please read the engine instruction manual on how to properly adjust the engine. Depends on the fuel and glow plug used, the carburetor idle screw may require fine adjustment of 1/4 to 1/2 turns away from the factory setting. (9) Fuel up the tank, move the throttle stick to idle, and connect a specially designed glow plug battery to the glow plug. (10)Use a 12 volt model engine electric start along with a 6 mm hex starter extension (sold separately) to start the engine. Otherwise, the main rotor may start spinning immediately after the engine is started. Always grab on the helicopter main rotor head when starting the engine. 44 Flying Adjustments (1) Tracking adjustment . . . When the two main rotor blades are in track it means their blade tips should follow the same path as they rotate. (1) Rev up the motor until the helicopter becomes light on its skids. (2) When the two main rotor blades are in track it means their blade tips should follow the same path as they rotate, then it's ok. increase throttle gently and not too much (3) When two blades are in track, the blade tips will appear overlapped as one look at the rotor tip path plane from the edge. out of track If the blades are out of track, then adjust one of the pushrods that connects to the main rotor blade pitch arm. Redo steps (1) to (3) until the blades are tracking properly. in track In hover, the main blades should be around 5. 5 to 6 degrees in pitch. 45 Flying Adjustments (2) Trimming: All helicopters are inherently unstable. But when a helicopter is properly trimmed, it will not drift away or yaw by itself quickly. (1) If the helicopter nose starts to yaw left or right, then use the transmitter trim to compensate: yaw right yaw left (A) situation: move to (b) (B) situation: move to (a) (2) If the helicopter rolls to left or right, then: rolls right rolls left (C) situation: move to (d) (d) situation: move to (c) (3) If the helicopter noses down or up, then: Noses down (E) situation: move to (f) (F) situation: move to (e) Noses up 46 Hover Training (1) Hovering is when the helicopter is floating in a stationary position in the air. Here is the procedure to practice hovering: (1) Make sure there is no spectator anywhere near the model helicopter. You, the pilot, should stand at least 10 meters (30 feet) behind and slightly to the side of the model helicopter. (2) Prior to lifting off, while the main rotor is spinning and the helicopter is on the ground, check the main rotor fore/aft and left/right cyclic to make sure the main rotor is tilting in the correct direction according to your cyclic command. Move the tail rotor control stick to make sure the helicopter nose will swing in the desired direction accordingly. (3) Increase the throttle/collective to lift the model helicopter skids off the ground to no more than 10 cm(4 inches). Initially, it will be very difficult to control the model to prevent it from moving. [. . . ] If not, then add some tape to the lighter blade near the blade tip until the two blades teeter in a level position. Hobby shops also sell blade balancers that are designed solely for balancing model helicopter blades. 50 In the event the model has crashed. Inspect the flybar, rotor shaft and the blade spindle to make sure they are not bent at all. If any item is damaged, it must be replaced by a new part to ensure safe operation. [. . . ]
