2. ROTOR BLADES CHECK
Unfold the main rotors to the flying position
as per the above pic ensuring they are
exactly perpendicular to the flybar and
paddles and that they are not damaged.
WARNING!
The main blades are factory fitted and should feel
'tight' in the rotor hub as they are unfolded to the
flying position. If the blades are too loose, this will
lead to incorrect and/or nodding flight behaviour.
N.B. Helicopter experts only:
This is the reverse of what you might expect...
please be assured the Twister requires the blades
to be reasonably tight in the blade holders - not
loose!
3. VISUAL CHECK
Check that all linkages, electrical
connectors are attached and that rotating
parts are free to rotate smoothly.
Check that all linkages move freely with no
binding or stiffness. Free off any linkages
that show any level of tightness or binding.
4. SWITCH ON TRANSMITTER
The transmitter is supplied in Mode II version where
the left stick controls height (climb or descent) and
tail rotor (yaw left or right). The right stick operates
the cyclic steering controls which are used to
pitch the helicopter nose up/nose down and to roll
the helicopter left or right. Note that the included
DVD depicts the use of a Mode I (throttle right)
transmitter. See pic below for Mode II layout.
1. Move the throttle stick and throttle trim of
your transmitter to the lowest (low throttle)
position.
2. Centre the trim controls for the 3 other
transmitter functions.
3. Extend the transmitter aerial fully.
4. Switch on the transmitter.
5. Check that the receiver aerial is unwrapped
ENTIRELY from its stowed location around
the right side undercarriage and is free
to dangle from the front of the helicopter
where it will not become caught in the tail
rotor.
6. To power up the helicopter, you must
connect the JST battery connector to the
matching lead emerging from the '4-in-1'
control unit.
Do this now - ensuring you are well clear of
main and tail rotors and that throttle stick
and trim are in the low position.
7. Observe the '4-in-1' status LED. Initially,
it will blink red, then blink green. After
the on-board computer has completed
satisfactory systems checks, it will glow
green continuously.
Do not move the helicopter during this
checking and calibration process.
WARNING!
Keep hands, clothing, eyes, animals and children
well clear when connecting power to this model
or flying it!
WARNING!
Do not operate this model with a collapsed or
partially collapsed transmitter (or receiver) aerial.
The model may suffer from interference and may
endanger your personal safety! Always extend
aerials fully. Never tape an aerial to any carbon
fibre helicopter components.
5. RANGE CHECK
Check that all controls operate without
interference at a minimum distance of 50
metres with transmitter and receiver aerials
extended.
WARNING!
At distances of greater than 50 metres, it will
become impossible to see your Twister clearly
enough to be able to control it safely. Do not fly at
50 metres distance or greater.
We strongly recommend you fly no further away
than 15 metres.
