INSTrUCTIONS FOr SaFe FlYINg
GENERAL FLyING TIPS:
• Always place the helicopter on a level
surface. An inclined surface can, under
certain circumstances, have a negative
impact on the starting behaviour of the
helicopter.
• Always move the controls slowly and
with a gentle touch.
• Always maintain visual contact with the
helicopter and do not look at the remote
control!
• Move the thrust control down again
somewhat as soon as the helicopter lifts
off from the ground. To maintain the
flying altitude, adapt the setting of the
thrust control.
• If the helicopter lowers, move the thrust
control slightly upward again.
• If the helicopter climbs, move the
control down slightly.
THE SUITABLE FLyING ENVIRONMENT:
The location in which the helicopter is flown should fulfil the following criteria:
• It should be an indoor location with still air. Insofar as possible, there should be no air
condition systems, heaters, etc., which could cause airflow.
• The room should be at least 10 metres long, six metres wide and three metres high.
• There should be no disruptive objects in the room (fans, lamps, etc.).
• When starting, make absolutely sure that all persons and animals – including the pilot
- are at least 1-2 metres away from the aircraft before the flight begins.
ATTENTION!
Liability insurance has been mandatory since 2005 for flying model aircraft and
helicopters outdoors. Contact your private liability insurer and make sure that your new
and earlier models are included in the insurance coverage. Request confirmation in
writing and keep it in a safe place. Alternatively, the DMFV offers a trial membership
free of charge online at www.dmfv.aero, which includes insurance.

• In order to fly along a curve, it often
suffices to tap the directional control
very slightly in the respective direction.
On initial flight attempts, there is a
general tendency toward excessive
movements of the helicopter controls.
Always move the controls slowly and
carefully. Never fast and fitfully.
• Beginners should only attempt to
master the thrust control after the trim
adjustment. The helicopter does not
necessarily have to fly straight at the
beginning - initially, it is more important
to maintain a constant height of
approximately one metre above the
ground by repeatedly tapping the thrust
control. Only then should the pilot practice
steering the helicopter left and right.

8 ChaNgINg The rOTOr BlaDeS
If the rotor blades of the helicopter are damaged and you must replace them,
proceed as follows:
8A Prior to installation, make sure that
you do not mix up the rotor blades.
The upper rotor blades are pictured on
the left; the lower rotor blades are on
the right (see Fig.).
8C Now carefully remove the rotor blade
from the mount.
TrOUBleShOOTINg
Problem: The rotor blades do not move.
Cause: • 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 helicopter stops and descends during flight for no apparent
reason.
Cause: • The battery is too weak.
Remedy: • Charge the battery.
Problem: The helicopter cannot be controlled with 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 helicopter only rotates around its axis clockwise or anti-clockwise.
Cause: • Excessive trim adjustment to the left or right.
Remedy: • Reset the trim adjustment by repeatedly tapping the trim button in the
opposite direction (see Item 6, Trim adjustment of the control).

8B Take a 1.5 mm Allen key and
a small pair of pliers and carefully
remove the screws on the rotor blade.
8D Carefully fit the new rotor blade
in the mount and tighten the screw.
Attention: Do not over-tighten the
screw. The rotor blade must have a
certain amount of play.
