4 CAlIBRATION
If the Quadrocopter drifts or can only be trimmed with difficulty while flying (yawing), try to
calibrate the Quadrocopter. Switch on the remote control and Quadrocopter for this purpose
(see instructions) and place the model on a level surface.
The slider (the left-hand stick on the remote control) must point downwards. Now move the slider
down as far as it will go and towards the right-hand corner and hold it there. Now quickly move
the control for pitching and rolling (the right-hand stick on the remote control) five to six times to
the left and right. The LEDs on the Quadrocopter will briefly flash. Then the calibration is finished.
5 CHANGING THE pROpEllERS
If the Quadrocopter‘s rotor blades are damaged and must be replaced, proceed as follows:
• Before fitting the propellers, make sure they are not mixed up. The Quadrocopter has
4 different propellers, which differ in colour and markings on the bottom:
• Front right: White, marking A
• Front left: White, marking B
• Rear right: Black, marking B
• Rear left: Black, marking A
• Carefully pull the defective propeller off the shaft.
• Carefully fit the new propeller onto the shaft again.
TROUBlESHOOTING

• The ON/OFF switch is in the "OFF" position.
• The battery is too weak or depleted.
remedy:
• Set the ON/OFF switch to the "ON" position.
• Charge the battery.
Problem: the Quadrocopter stops and descends during flight for no apparent reason.
Cause:
• The battery is too weak.
remedy:
• Charge the battery.
Problem: It isn't possible to control the Quadrocopter using the remote control.
Cause:
• The ON/OFF switch is in the "OFF" position.
• The batteries were not inserted correctly.
• The batteries do not have enough power.
remedy:
• Set the ON/OFF switch to the "ON" position.
• Check whether the batteries are inserted correctly.
• Insert new batteries.
Problem: the Quadrocopter only turns on its vertical axis or rolls over when started
or does not lift off.
Cause:
• Incorrect arrangement of propellers.
remedy:
• Install the propellers as outlined in the manual.
