Thank you for buying the Twister 400
Sport. It is the latest 400 size fixed pitch
helicopter with 4-channel R/C, 2.4GHz
radio and excellent stability. The Twister
400 Sport is an ideal choice for the
beginner helicopter pilot as it features
professional 4-channel operation
and stable flight characteristics.
Intermediate/Advanced pilots will
also enjoy the more advanced flight
characteristics of the Twister 400 Sport.
Small and lightweight, it can be flown
indoors or outdoors in calm conditions so
almost anyone can enjoy the fun of R/C
helicopter flight.
nEw To R/C
hEliCopTERS?
This model is not a toy. If you are new to
RC helicopters, please do not expect to
be able to open the box and immediately
‘fly around’. RC helicopters are fun to
fly but require some time and training in
order to be flown successfully.
If this is not what you were expecting,
we advise you not to buy this model.
Although the Twister 400 Sport is
relatively easy to fly, please note that we
do not guarantee that by following the
information included with this product
you will be bound to achieve successful
helicopter flight. Neither do we guarantee
you will not break anything!!
AboUT ThE FlyinG AREA
REQUiREd
The Twister 400 Sport is designed for
indoor or outdoors in less than 5mph of
wind. Ensure you have at least 2 meters
of clear space all around the Twister 400
Sport before attempting to take off. A
hard, flat surface clear of all obstacles
is recommended for taking off. Because
of its size, the Twister 400 Sport can be
flown in virtually any size room. However,
you should fly only where it is safe to do
so and bear in mind the smaller the room
the more likely you are to experience
backwash from the rotors turning which
will effect the stability of the helicopter.
AboUT TRAininG,
CRAShES & SpARE
pARTS
The Twister 400 Sport Twister has been
designed to be strong and very easy to
repair, however, the helicopter is not
invulnerable and most people will tip their
helicopter over or break parts during their
flying career. This is quite normal. All
parts are available as spares from your
local model shop. If repair is necessary,
carefully remember the order in which
you remove items so you may put them
can replace them in the reverse order.
CRASH DAMAGE IS NOT
COVERED BY WARRANTY.

bindinG TRAnSmiTTER To RECEiVER
A working 2.4GHz transmitter and receiver (in the helicopter) have a coded, ‘bound’
relationship with each other. The setting up of this relationship is known as ‘binding’.
In a ‘bound’ transmitter/receiver relationship the receiver (and therefore the
helicopter it is in) is bound to your transmitter and can only respond to signals
received from that transmitter. It will not respond to any other device or transmitter.
Once a transmitter is bound to it’s receiver, re-binding of transmitter and receiver is
not normally required.
HOW DO I BIND RECEIVER AND TRANSMITTER?
1. Make sure the throttle is in the lowest position, that is, throttle stick towards you,
then switch on the transmitter.
2. Connect helicopter battery and place on a flat surface, then switch on the
helicopter.
3. Wait for at least 5 seconds after switching on the helicopter.
4. Pick up the heli and hold it by the landing skids in one hand, keeping clear of the
rotors. Gently move the sticks on the transmitter side to side to confirm the heli
is responding. Then gently move the throttle up until the rotors just start to spin.
Your helicopter is now ready for use.
5. It is possible to have up to five Twister 400 Sport helicopters operating in the
same vicinity at the one time. However it is very important to only turn on
the heli’s one at a time (not all at once). The procedure is Turn on the First
Transmitter then turn on the First Heli. When it is responding as detailed above,
Turn on the Second Transmitter then turn on the Second Heli and so on until up
to five Twister 400 Sport helicopters are ready for flight. Double check that each
transmitter is only controlling one heli, then all five can be flown together.
TRAnSmiTTER USAGE
TRANSMITTER AERIAL POSITIONING
The transmitter aerial can be angled to optimise the transmitted signal. During
operation keep the aerial pointing upwards at all times. Do not fly with the aerial
pointing downwards. Avoid pointing the aerial directly at your model.
Keep the aerial pointing up–but
not directly at the model

8Twister 400 Sport Instruction Manual
hEliCopTER ChARGinG inSTRUCTionS
Note: Charge the helicopter battery before using your Twister 400 Sport for the first
time.
1. Turn OFF the power point on the wall.
2. Make sure the helicopter is switched off and the black
battery plug is disconnected
3. Insert the AC Charger into the power point and turn on.
4. Carefully connect the white charge plug on the heli to
the charger plug ensuring it is the correct way around.
You should not need to force it.
FORCING THE CHARGE PLUG IN THE WRONG WAY AROUND
MAY DAMAGE THE FLIGHT BATTERY OR ELECTRONICS.
5. Charging will take approximately 120min with the following lights: Red light for
charging, orange light for almost charged and green light for fully charged.
6. When the light turns green, disconnect the battery from the charge lead.
7. Unplug the AC Charger from the power point.
DO NOT LEAVE UNATTENDED WHILE CHARGING
pREpARinG FoR FliGhT
TURNING ON
1. Before setting the ON/OFF switch of the transmitter to ON, make sure the throttle
stick is down, in its lowest position.
2. Set the ON/OFF switch of the transmitter to ON. The LED above the ON/OFF
switch will flash several times then glow RED.
Note: Always turn your transmitter ON first, then your helicopter.
3. Align the red plug and black plug and carefully push the battery leads together
taking great care to connect it the correct way round, red to red and black to
black. You should not need to force it. Do not attempt to plug it in the other way
around or you will damage the heli and/or the battery. Then switch the heli on.
4. Place the helicopter on the ground with its tail facing towards you.
5. Make sure you have a clear indoor space of at least 3 metres wide and two
metres high when you are learning to fly.
Note: If there are two or more Twister 400 Sport helicopters to be operated in the one
area, please refer to Item 5 on page 7, BEFORE turning on multiple helicopters.

TRimminG ThE hEliCopTER (modE 1)
Gently apply throttle until the rotor blades start to turn, keep advancing the throttle
until the helicopter leaves the ground and begins to hover.
The model should be stable and centred in the hover to produce the best flight
performance. If you find that your model has a tendency to drift out of the hover then
you can use the trim sliders detailed on page 5 to correct it.
THROTTLE TRIM - RIGHT STICK
Decreasing throttle power
If the rotor blades on the model are rotating when you plug
in the battery and no throttle is applied, decrease the throttle
trim by sliding the trim slider next to the throttle stick,
backwards or down.
Increasing throttle power
If the rotor blades do not start to rotate when you raise the
throttle stick, increase the throttle trim by moving the trim
slider next to the throttle stick, forward or up.
YAW TRIM - LEFT STICK
The model rotates when no yaw control is applied
If the model rotates to the left or the right slide the yaw
trim slider in the opposite direction to correct it, e.g., If the
model rotates left, slide the trim slider right, until the model
is centred.
FORE/AFT CYCLIC TRIM - LEFT STICK
The model drifts forwards (fore) or backwards (aft) when
the fore/aft cyclic stick is centred
If the model drifts forwards or backwards slide the trim
slider in the opposite direction to correct it, e.g., If the model
drifts forwards, slide the trim slider backwards (aft) trim until
the model is centred.
LEFT/RIGHT CYCLIC TRIM - RIGHT STICK
The model rolls/drifts to the side when left/right cyclic
stick is centred
If the model rolls to the left or right, slide the trim slider to
correct it, e.g., If the model drifts to the left, slide the trim
slider to the right, until the model is centred.
Once you have trimmed your model reduce throttle and
land. Switch off the helicopter and disconnect the battery.
Then read through the next section on how to use the other
controls on the helicopter.

TAKING OFF
If you have never flown an R/C helicopter before, we recommend learning to
fly in the beginner mode before progressing to advanced mode. See page 6 for
information on how to switch between the modes.
1. Gently move the throttle stick up. The main rotor blades will start to spin.
2. Keep advancing the throttle stick until the helicopter leaves the ground.
3. To begin with, move the throttle stick up and down in very small movements to
find the correct amount of throttle to keep the helicopter at a constant height.
4. If you get into trouble or loose orientation, slowly move the throttle stick to its
lowest position and the helicopter rotors will slow down and stop spinning and
the helicopter will land. This is a much better option than allowing the helicopter
to crash into something with the rotor blades spinning.
LEFT-RIGHT ROTATION
1. Now that you have the helicopter hovering you can learn to turn it around by
using the yaw control.
2. To make the nose turn to the left, move the stick to the left. Centre the stick to
stop the helicopter rotating to the left.
3. To make the nose turn to the right, move the stick to the right. Centre the stick to
stop the helicopter turning to the right.
Yaw left
- Rotate nose to the Left
Yaw right
- Rotate nose to the Right

12 Twister 400 Sport Instruction Manual
FORE/AFT CYCLIC CONTROL
1. Once you have got used to hovering the model and turning it you can try moving
it around the room using the for/aft cyclic control, move the stick forward to
make the helicopter move forwards. Centre the stick to stop the helicopter
moving forwards.
2. Move the stick backwards, or towards you to make the helicopter move
backwards. Centre the stick to stop the helicopter moving backwards.
Forwards -
Fore cyclic
Backwards -
Aft cyclic
LEFT/RIGHT CYCLIC CONTROLS
1. Now using the left/right cyclic stick, move the stick left make the helicopter roll
to the left. Centre the stick to stop the helicopter rolling to the left.
2. Move the stick right to make the helicopter roll to the right. Centre the stick to
stop the helicopter rolling to the right.
Roll to the Left - Left cyclic Roll to the Right - Right cyclic
WHEN YOU HAVE FINISHED FLYING, SWITCH OFF THE
HELICOPTER AND UNPLUG THE BATTERY.
THEN TURN OFF THE TRANSMITTER.
3. As you get more confident, you can combine movements at the same time to
fly circles, figure eights, climbing and descending circles, nose in flying and
precision landings on objects. The possibilities are endless. ENJOY!
