GENERAL FLyING TIPS:
• Always practice without the Quick-Slow
button pressed (slow flight) until you
have mastered flying the helicopter;
then you can switch to fast flight!
• 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 thrust
control down slightly.
• 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 approxi-
mately one metre above the ground by
repeatedly tapping the thrust control.
Only then should the pilot practice
steering the helicopter left and right.
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.
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 rotor blades are marked with "A"
and "B" (see Fig.). Type "A" rotor blades
are mounted on top and Type "B" rotor
blades are mounted on the bottom.
8B
Use a Phillips screwdriver to care-
fully 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.
8C
Now carefully remove the rotor blade
from the mount. Attention! The rotor
blades have small brass sleeves - do not
lose them!
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.
• The antenna of the radio remote control is not inserted correctly and/or
is not completely extended.
Remedy:
• Set the ON/OFF switch to the "ON" position.
• Check whether the batteries are inserted correctly.
• Insert new batteries• Check the antenna and extend it completely.
Problem: The helicopter only rotates around its axis clockwise or anti-clockwise.
Cause:
• Excessive trim adjustment to the left or right, possibly due to the
incorrect position of the trim knob.
Remedy:
• Reset the trim adjustment by turning the trim knob to the neutral
position (see section 6, Trim adjustment of the control).
