7A Take off or increase altitude by
carefully moving the control for thrust
(2A) forward.

carefully move the control for forward/
backward and clockwise/anti-clockwise
rotation (2D) to the left, as long as the
helicopter tail is facing toward the pilot.

for forward/backward flight and right/
left rotation (2D) carefully forward.
instructions For saFE FlYing
GENERAL FLyING TIPS:
• Always place the model on a level surface. An inclined surface can, under certain
circumstances, have a negative impact on the starting behavior of the model.
• Always operate the controls slowly and with a gentle touch.
• Always maintain visual contact with the model and do not look at the remote control!
• Move the thrust control down again somewhat as soon as the model lifts off from
the ground. Maintain flying altitude by adjusting the thrust controller.
• If the model lowers, move the thrust control slightly upward again.
• If the model climbs, move the thrust control down slightly.
• In order to fly along a curve, it often suffices to tap the control for forward/back and
clockwise/anti-clockwise rotation very slightly in the respective direction.
There is a general tendency during preliminary attempts at flight to operate the
model's controls too aggressively. The control for forward/backward and clockwise/
anti-clockwise rotation should always be moved slowly and carefully. Never fast and
fitfully.
• Beginners should first master trimming before attempting to master the thrust control-
ler. The model does not necessarily have to fly straight at the beginning – initially, it is
more important to maintain a constant height of approximately one meter above the
ground by repeatedly tapping the thrust control. Only then should the pilot practice
steering the model left and right.
SUITABLE FLyING ENVIRONMENT:
The location in which the helicopter is flown should fulfil the following criteria:
• It should be an indoor location without any wind. Insofar as possible, there should be
no air conditioning systems, heaters, etc. that can cause air currents.
• The room should be at least 10 metres long, six metres wide and three metres high.
• No disruptive objects, such as fans, lamps, etc. should be present in the room.
• When initialising take-off, make absolutely sure that all persons and animals
– including the pilot – are at least 1-2 metres removed from the aircraft before flight
begins.
• Always watch the aircraft to ensure it does not fly into and injure the pilot, other
people or animals.

7B Land or decrease altitude by moving
the control for thrust (2A) backward.
Only minimal corrections to the controller
are necessary to ensure smoothing flying
of the helicopter!
7D To fly along a right-handed curve,
carefully move the control for forward/
backward and clockwise/anti-clockwise
rotation (2D) to the right, as long as the
helicopter tail is facing toward the pilot.
7F Fly backward by moving the control
for forward/backward flight and
clockwise/anti-clockwise rotation (2D)
carefully back.
8 changing thE rotor bladEs
If the rotor blades of the helicopter should become damaged, they must be replaced.
To do so, proceed as follows:
8A Prior to installation, make sure that you do not mix up the rotor blades.
The rotor blades are marked with A (top) and B (bottom).
8B Unscrew the blade retaining screw in anticlockwise motion.
8C Pull the rotor blade down and at an angle to remove it.
8D Now fit the new rotor blade and carefully screw in the blade retaining screw in
clockwise motion. Attention: The rotor blade must rotate freely.
troublEshooting
Problem: The rotor blades do not move.
Cause:
• The ON/OFF switch is set to 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 helicopter 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 helicopter using the remote control.
Cause:
• The ON/OFF switch is set to 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 helicopter only rotates around its axis clockwise or
anti-clockwise.
Cause:
• Excessive trimming to the left or right.
Remedy: • Reset the the left/right trim adjustment in the opposite direction
(see point 6: Adjusting the Trim Controller).
