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

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.
