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.
8 CHANGING THE ROTOR BLADES
If the helicopter's rotor blades have been 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 "B" rotor blades are mounted
on top and Type "A" rotor blades are mounted on the bottom.
Note:
Only minimal corrections of the controls are necessary for a smoothing flying
behaviour of the helicopter!
7B
Land or decrease altitude by moving
the control for thrust backward. Only
minimal corrections to the controller are
necessary to ensure smoothing flying of
the helicopter!
7D
Fly backward by moving the controller
for forward/backward flight and right/left
rotation carefully backward.
7F
Turn the helicopter around clockwise
by moving the controller for forward/
backward flight and right/left rotation to
the right.
7A
Take off or increase altitude by
carefully moving the control for thrust
forward.
7C
Fly forward by moving the controller
for forward/backward flight and right/
left rotation carefully forward.
7E
Turn the helicopter around anti-
clockwise by moving the controller for
forward/backward flight and right/left
rotation to the left.
7 FLIGHT CONTROL
6 TRIM ADJUSTMENT OF THE CONTROL
The correct trimming is a basic requirement for achieving fault-free flying from the
helicopter. Its adjustment is simple, but it requires some patience and a feel for it.
Please observe the following instructions precisely: Carefully move the thrust control
up and raise the helicopter approximately 0.5 to 1 metre in altitude.
If the helicopter begins to automatically rotate clockwise, rotate the left/right trim
adjustment anti-clockwise until the helicopter no longer rotates on its own.
6A If the helicopter quickly or slowly rotates clockwise by itself…
If the helicopter begins to automatically rotate anti-clockwise, rotate the left/right trim
adjustment clockwise until the helicopter no longer rotates on its own.
6B If the helicopter quickly or slowly rotates anti-clockwise by itself…
INSTRUCTIONS FOR SAFE FLYING
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 operate 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 controller somewhat down again once the helicopter has lifted off
from the ground. Maintain flying altitude by adjusting the thrust controller.
• If the helicopter descends, move the thrust controller slightly upward again.
• If the helicopter climbs, move the thrust controller down slightly.
• To fly along a curve, tapping the directional controller very slightly in the respective
direction often suffices. There is a general tendency during preliminary attempts at
flight to operate the helicopter's controls too aggressively. Always operate the
controls slowly and carefully. Never fast and fitfully.
• Beginners should first master trimming before attempting to master the thrust
controller. 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.
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.
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.
