Introduction Thank you for your purchase of our product. In order to enjoy all the benefits of your helicopter, we recommend you carefully read the entire manual before you begin working with this model. After you have read the manual please store it in a safe place for future reference. Warning 1. Walkera helicopters are not toys. They are a complex combination of electronics and mechanics which produce an aerodynamic rotorcraft. All models require proper setup and exacting adjustments to avoid accidents.
Cautions 1. Because the helicopter is operated by radio control, it is important to make sure you are always using fresh and/or fully charged batteries. Never allow the batteries to run low or you could lose control of the helicopter. 2. Do not allow any of the electrical components to get wet. Otherwise electrical damage may occur. 3. You should complete a successful range check of your radio equipment prior to each new day of flying, or prior to the first flight of a new or repaired model. 4.

Flybar Set Assembly Flybar block Flybar 1. Let the location notch of flybar block aim at the flybar, and press the flybar block till the flybar reaches the end of notch; Insert one end of the flybar through hole 1 (Fig. 6-1); Flybar block sleeve * * Fig. 6-1 Location notch 2. Let the location notch of flybar block aim at the inner location mast of flybar block sleeve, and press the flybar block along the inner location mast into the sleeve (Fig. 6-2); 90* 3.
Fig. 7 2. CG balance. Put your helicopter on a horizontal ground and make the flybar perpendicular to the tail truss of your helicopter. Lift your helicopter using your index fingers to support the two sides of flybar, and check the balance. The tail boom should be level with the ground. If it is not, move the battery pack backwards or forwards to balance. Always check the Center of Gravity (CG) with the battery pack and canopy installed (Fig. 8).
Main Rotor Blade Adjustment Fig. 10 1. Main rotor blade inspection. (1) Inspect whether the fixing screw of the main rotor blades are too tight or loose. Extreme tightness or loosing of the blades will result in instable flight. (2) Inspect the blade tracking problem. Blade tracking will lead to instable flight. 2. Main rotor blade adjustment. (1) Keep the fixing screw of the main rotor blades not too tight or too loose. (2) Lengthen or shorten the short ball linkage if the blade tracking is existed (Fig.
