2 IntroductionThank you for your purchase of our product. In order to enjoy all the benefits of your helicopter, we recommend you carefully read the entire manualbefore you begin working with this model. After you have read the manual please store it in a safe place for future reference.Warning5. Before flying your helicopter, please undraw the upper and lower blades and make sure the left and right blades are in line.Notice: please let the motors cool 10 minutes after your helicopter flies every one of fully charged battery packs, and then continue your next flight; otherwise, the motors of your helicopter will take a high risk of burning or damage!1. Walkera helicopters are not toys. They are a complex combination of electronics and mechanics which produce an aerodynamic rotorcraft. Allmodels require proper setup and exacting adjustments to avoid accidents. We accept no liability for damage and/or consequent damage arisingfrom the use or misuse of the products due to improper construction methods, use or operation, It is your responsibility to operate this highly advanced model in a safe manner.2. When charging the battery, do not overcharge. Overcharging may result in fire or explosion. When the battery is hot during charging, please stop charging at once. Use specified charger only. Never short circuit! Proper disposal of the battery is your responsibility. 3. Children under 14 years old are strictly forbidden from flying the helicopter. Please do not allow children or adults in the designated flying area.4. Any situations that occur during flight, that cause the rotor blades to stop spinning or that result in a serious ground strike and cause damge to the helicopter could initiate a fire or explosion. If this type of situation occurs, IMMEDIATELY move the throttle stick to it’s lowest position.
3CautionsDon't fly your helicopter at the places with these signs1. 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. If the helicopter gets dirty, don’t use any solvents to clean it. Solvents will damage the plastic and composite parts.5. Always turn on the transmitter before plugging in the flight battery and always unplug the flight battery before turning off the transmitter.6. Never cut the receiver antenna shorter or you could lose control of the helicopter during flight.7. When flying the helicopter, please make sure that the transmitter antenna is completely extended and is pointed up toward the sky, not down toward the ground.

Unscrewthe fixing screw of linkage using cross screwdriver and fix the linkage of another sideusing the screw. And then remove the throttle arresting spring to fix in your expectingside. Unscrew the fixing screws of plastic flakes to remove the plastic flakes, and thenfix them in your expecting side using the screws. In this way physical refit has beenfinished (Fig. 4).
7Flybar Set Assembly1. Let the location notch of flybar block aim at the flybar, and press the flybar blocktill the flybar reaches the end of notch; Insert one end of the flybar through hole 1 (Fig. 6-1);2. Let the location notch of flybar block aim at the inner location mast of flybar blocksleeve, and press the flybar block along the inner location mast into the sleeve(Fig. 6-2);3. Counterclockwise rotate 90*the flybar block sleeve (Fig. 6-2), let the hole 1of flybar block sleeve aim at the hook of flybar, and then push the flybar block set outside and make the hook completely insert into the hole 2 (Fig. 6-3).Note: the flybar set will be thrown off at high speed in flying when it is mountedimproperly. A serious damage to people or property may be taken place.Fig. 6-1Fig. 6-2Fig. 6-390* Flybar blockLocation notchFlybar block sleeve**FlybarFlybar block sleeveFig. 5Battery Mounting and Adjustment1. Battery pack mounting. Place the battery pack in the correct position of your helicopter (Fig. 7).
8Battery packlocationFlybarTail trussHorizontal level ofthe swashplateServo linkage rod2. Swashplate adjustment. If the swashplate is not in a horizontal level,adjust via the following steps: *Elevator servo and aileron servoadjustment. Firstly unscrew the screw of servo bellcrank to take the bellcrank off , and then re-connect to the helicopter battery pack andawait the servos reposition. After the reposition is ready, adjust thebellcrank to be in horizontal state and then tighten the screw of bellcrank.*Servo linkage rod adjustment. Adjust the servo linkage rod to parellel to swashplate bottom level (Fig. 9) .Fig. 7Fig. 8Fig. 9Aileron servoElevator servoSwashplate Adjustment2. CG balance. Put your helicopter on a horizontal ground and make theflybar perpendicular to the tail truss of your helicopter. Lift your helicopterusing your index fingers to support the two sides of flybar, and checkthe balance. The tail boom should be level with the ground. If it is not,move the battery pack backwards or forwards to balance. Always checkthe Center of Gravity (CG) with the battery pack and canopy installed(Fig. 8). Note: If you can not obtain a level condition a very small amount of weight may be added the tail. It is possible with the battery upgrade to a LiPo of 1250 mAh that a nose heavy condition may occur.1. Swashplate check. Pull down the throttle stick and throttle trim tothe lowest position, and put the elevator trim and eileron trim in theneutral position. Check whether the swashplate is in a horizontal level.
9Fixing screwShort ball linkageFig. 10Main Rotor Blade Adjustment1. 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 bladeswill 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 bladesnot too tight or too loose. (2) Lengthen or shorten the short ball linkage if theblade tracking is existed (Fig. 10).
