intRoduction
Thank you for buying the Twister
400 Sport V2. It is the latest 400 size
fixed pitch helicopter with 4-channel
R/C, 2.4GHz radio and possesses
excellent flight stability. The Twister
400 Sport V2 is an ideal choice for
the beginner helicopter pilot as it
features professional 4-channel
operation combined with stable flight
characteristics. Intermediate/Advanced
pilots will also enjoy the more advanced
flight characteristics of the Twister 400
Sport V2.
V2 features an improved rotor head with
better flight performance and better
clearance between blades and boom to
reduce accidents. The transmitter has
been ugraded with digital trims and a
metal carrying handle. New anodised
metal frames, free training undercarriage
and a sparkling new colour scheme
are just some of the many additional
improvements to your V2.
Small and lightweight, the V2 can be
flown indoors or outdoors in calm
conditions so almost anyone can enjoy
the fun of R/C helicopter flight.
A. NEW TO R/C HELICOPTERS?
This model is not a toy.
It can accelerate very rapidly in flight
and the rotating blades are capable of
inflicting severe injuries if the model is
not operated responsibly!
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, some patience and some
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 V2 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!!
B. FLYING AREA
The Twister 400 Sport V2 is designed
for indoor or outdoors flight in less than
5mph of wind. Ensure you have at least
3 metres of clear space all around the
Twister 400 Sport V2 before attempting
to take off. A hard, flat surface clear
of all obstacles is recommended for
training. Because of its size, the Twister
400 Sport V2 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
the effects of rotor downwash causing
instability and therefore making the
helicopter more difficult to control.
C. TRAINING, CRASHES & SPARE
PARTS
The Twister 400 Sport V2 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 and/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. Unfortunately, crash damage is not
covered by warranty.

Vital Safety
pRecautionS!
Please be aware that rotating blades
can inflict painful—at the very least—
and possibly serious injury or damage
to people, animals or objects should the
rotors strike someone or something.
We recommend you use protective
eyewear when operating this model and
that you read the manual carefully before
operating your Twister 400 Sport V2.
Radio controlled models can reach high
speeds and cover significant distances
rapidly if control is lost. This model is
capable of speeds of around 20mph
(30kph) or greater. The model must
therefore be used responsibly and with
great care generally.
The model operates on the 2.4GHz radio
band using the latest technology, thereby
providing probably the best interference
rejection for any R/C frequency in use
in the UK today. However, this does
not make it invulnerable to outside
interference!
Interference might cause the model to
go out of control or stop responding!
Therefore, in the UK, we recommend you
study and observe the model flying safety
codes and bulletins of the British Model
Flying Association which can be found at
the following web address:
http://www.bmfa.org
In Australasia, please contact your
hobby supplier.
Please note the following additional
safety precautions:
f Not suitable for children under 14
years.
f If you are completely new to R/C
helicopters we advise that you seek
advice from an experienced R/C
helicopter pilot before attempting to
fly this model.
f Always turn on the transmitter first
then switch on the helicopter.
f When you have finished flying
always switch off and disconnect
the battery on the helicopter first,
then turn off the transmitter.
f Only for use indoors or outdoors in
calm conditions.
f Do not fly near electrical or wireless
equipment or magnetic objects.
f Always let the battery cool down
before recharging.
f Always recharge the battery after
use, especially if it is going to be
stored and not used for a while.
f Be careful to insert the battery the
correct way round, do not force any
connectors.
f Only use the AC charger provided
with this model to charge the
helicopter battery.
f Never operate your model closer
than 10 feet to yourself, other people
or objects!
f Never operate near free-range
animals or children!
f Never wear loose clothing or ties!
f Always use protective eyewear
when operating this model!
If any of this information is unclear,
DO NOT operate this model!
