Twister Bell 47
PREPARING FOR FLIGHT
1. UNPACK YOUR TWISTER BELL 47
1. Carefully remove the model and other items
from the packaging.
2. Screw the transmitter aerial into its socket
in the top of the transmitter.
3. Insert 8AA alkaline batteries into the
transmitter battery compartment being
careful to observe battery polarity.
4. Unwrap the receiver aerial ENTIRELY from
its stowed location and leave it free to hang.
WARNING!
RC flight is achieved through low power RF
transmissions and is susceptible to interference.
It is important to route the receiver aerial
directly away from the helicopter and away from
interference hazards.
Useful tip ........................... Although the Twister
Bell 47 is very strong, all model helicopters require
careful handling and a delicate touch. In particular,
take great care with the electrical connections
to and from the '4-in-1' control unit and do not
overtighten any screws.
2. FITTING THE FLYBAR
1. Carefully snap fit the flybar unit into the
mouldings at the top of the main shaft and
retain with the single screw supplied. Do not
overtighten. The flybar must be free to rock
unimpeded with no friction. See pic above.
2. Snap the plastic flybar link into position on a
main blade pitch arm as shown above.
3. CHARGING THE FLIGHT BATTERY
2
The Lithium polymer (Li-po) flight battery is supplied
in a partially charged state. The Li-Po fast charger is
designed to automatically charge the Li-Po battery
in about 1 hour from a discharged state.
The charger requires a 12 volt DC source.
Use either:
5510050 12 volt sealed gel cell modelling battery, or
4460049 Ultrapower 12V 10A power supply (3 PIN).
1. Connect the charger to your power source.
The 'POWER' LED will flash red.
2. Connect the Li-po battery to the charger.
The green LED will light and the red LED will
glow solid red.
3. When the battery is fully charged the green
LED goes out. Disconnect the battery from
the charger.
4. Disconnect the 12V power source from the
charger.
Never use other types of charger - the battery may
explode! Never attempt to charge a hot battery,
always let it cool down. Always disconnect the
battery from the charger when not in use.
WARNING!
Dangerous if treated improperly!
Please take time to read the supplementary
instructions on charging Lithium Polymer batteries.
4. FITTING THE FLIGHT BATTERY
1. Place the charged battery pack onto the
battery holder using Velcro supplied and
secure in place with rubber band supplied.
Do not connect to the RC equipment yet.
5. CHECKING CENTRE OF GRAVITY
The helicopter must balance on the main shaft. This
means that when the helicopter is lifted by the rotor
head it hangs perfectly straight and level.
It should hang neither nose down nor tail down.
Adjust the position of the battery until this is so.
