Thank you for buying the Mini Twister
Sport. It is the latest mini fixed pitch
helicopter with 4-channel R/C, 2.4GHz
radio and excellent stability. Mini Twister
Sport is an ideal choice for the beginner
helicopter pilot as it features professional
4-channel operation and stable flight.
Intermediate/Advanced pilots will
also enjoy the more advanced flight
characteristics of the Mini Twister Sport.
Small and lightweight, it can be flown
almost anywhere so almost anyone can
enjoy the fun of R/C helicopter flight.
nEw To R/C
hEliCopTERS?
The 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 Mini Twister Sport is 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 Mini Twister Sport is designed for
indoor use only. A hard, flat surface
clear of all obstacles is recommended
for take offs. Because of its size, the Mini
Twister 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 Mini Twister Sport 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
supplier. Study the exploded view of the
helicopter carefully to understand the
relationship between parts and how to
replace them if necessary. 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 exclusively 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.
However, by binding your transmitter, for example, to a friend’s Mini Twister Sport,
the unique relationship between your original transmitter and receiver in your Mini
Twister Sport will be broken. Should you wish to - or need to, re-establish or ‘bind’
your transmitter with your receiver once more; proceed as follows:
HOW DO I RECOGNISE WHEN MY RECEIVER IS NOT BOUND?
Upon connecting the battery in the model the internal LED will flash on and off
slowly regardless of whether the transmitter is switched on or not. Even when the
transmitter is switched on; no control or change in the slow flash of the LED will be
seen.
HOW DO I BIND RECEIVER AND TRANSMITTER?
1. Switch off the transmitter.
2. Connect helicopter battery.
3. Within 5 seconds of connecting the battery to the helicopter press the throttle
stick down as if it were a button and turn on the transmitter
4. The internal LED will flash and then go solid and the transmitter will emit a
succession of beeps and stop.
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

Note: Charge the helicopter battery before using your Mini Twister Sport for the
first time.
1. Turn on the computer power switch
2. Plug the USB charge lead into a spare USB slot in the computer
3. Carefully connect the battery to the charge lead ensuring it is the correct way
around. You should not need to force it. The light on the USB charge lead will
glow solid RED.
FORCING THE CHARGE PLUG IN THE WRONG WAY AROUND
MAY DAMAGE THE FLIGHT BATTERY OR ELECTRONICS.
4. When the battery has finished charging the light will go off.
5. Disconnect the battery from the charge lead.
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 glow RED.
Note: Always turn your transmitter ON first, then your helicopter.
3. Align the red identifying arrows and carefully push the battery into the battery
bay in the bottom of the helicopter taking care to connect it the correct way
round. You should not need to force it.
4. The internal LED will flash quickly and then go solid, this means the helicopter is
bound to the transmitter and ready to fly.
Note: If the light does not go solid and continues to flash see “BINDING THE
TRANSMITTER AND RECEIVER” on page 7.
5. Place the helicopter on the ground with its tail facing towards you.
6. Make sure you have a clear indoor space of at least 3 metres wide and two
metres high when you are learning to fly.

TRimminG ThE hEliCopTER (modE 2)
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 buttons detailed on page 5 to correct it.
THROTTLE TRIM - LEFT 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 pressing the lower trim button on the throttle stick
Increasing throttle power
If the rotor blades do not start to rotate when you raise the
throttle stick increase the throttle trim by pressing the upper
trim button on the throttle stick.
YAW TRIM - LEFT STICK
The model rotates when no yaw control is applied
If the model rotates to the left or the right press the opposite
yaw trim button to correct it, e.g., If the model rotates left
press the right trim button until the model is centred.
FORE/AFT CYCLIC TRIM - RIGHT STICK
The model drifts forwards (fore) or backwards (aft) when
the fore/aft cyclic stick is centred
If the model drifts forwards or backwards press the opposite
trim button to correct it, e.g., if the model drifts forwards
apply 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 press the opposite trim
button to correct it, e.g., if the model drifts to the left apply
right Yaw trim until the model is centred.
Once you have trimmed your model reduce throttle to land,
disconnect the battery and read through the next section on
how to use the other controls on the helicopter.

FliGhT ConTRolS
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 7 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

11
www.jperkinsdistribution.co.uk
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
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!
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, UNPLUG THE BATTERY
FROM THE HELICOPTER TO TURN IT OFF, THEN TURN OFF
THE TRANSMITTER.
