gENERAL FLyINg TIPS:
• Always place the helicopter on a level
surface. An inclined surface can, under
certain circumstances, negatively effect
the helicopter during take-off.
• 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. Maintain
flying altitude by adjusting the
thrust controller.
• If the helicopter lowers, move the thrust
control slightly upward again.
• If the helicopter climbs, move the thrust
control down slightly.
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 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.
• 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.
WARNINg!
Flying model aircraft and helicopters outdoors has required mandatory liability
insurance since 2005. Contact your private liability insurer and make sure that your
new and earlier models are included in your insurance coverage. Request written
confirmation and keep this 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 helicopter's rotor blades are damaged, they must be replaced.
Proceed as follows:
Prior to installation, make sure that you do not mix up the rotor blades.
The rotor blades are marked with "A" and "B" (8A). Type "A" rotor blades are
mounted on top and Type "B" rotor blades are mounted on the bottom.

• In order to fly along a curve, it often
suffices to tap the directional control
very slightly in the respective direction.
There is a general tendency during
preliminary attempts at flight to operate
the helicopter's controls too aggres-
sively. Always operate the controls
slowly and carefully. Never fast and
fitfully.
• Beginners should only attempt to
master the thrust control after the trim
adjustment. It is not necessary for the
helicopter to fly straight at first. It is far
more important to maintain a constant
height of approximately one metre
above the ground by repeatedly tapping
the thrust controller. Only then should
the pilot practise steering the helicopter
left and right.
8B Use a Phillips screwdriver to carefully remove the screws on the rotor blade.
8C Now carefully remove the rotor blade from the mount.
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.
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: It isn't possible to control the helicopter 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 helicopter only rotates around its axis clockwise or
anti-clockwise.
Cause: • Excessive trim adjustment to the left or right.
Remedy: • Reset of the left/right trim adjustment in the opposite direction
(see point 6, Steering trim adjustment).
