12 volt DC charger
Connect the nicad to the mains
charger (observing correct polarity)
and charge for 2 hours, checking periodically that the battery is not warm.
IMPORTANT
When the battery is charged from new
for the first time, make a note of the
time required for the battery to become warm to the touch. At this point
the battery will be fully charged. When
this occurs, disconnect the battery
and record the charging time. This is
the correct length of time required
for battery charging and should be
observed when recharging the battery
from a completely discharged state.
IMPORTANT
If the battery gets warm, stop charging immediately. A warm battery
indicates the battery is charged.
If the battery becomes hot to the touch (around
40 degrees Centigrade): STOP CHARGING
IMMEDIATELY!
DO NOT CHARGE LONGER THAN 2 HOURS
Please note that nicad batteries
require up to 5 or 6 charge and discharge cycles before reaching peak
capacity. As long as the battery is
not damaged by overcharging and/or
overheating; you can expect to enjoy
around 500 flights (complete charge/
discharge cycles) from one Nicad battery!
12V DC FAST CHARGER USE
 1.
The fast charger is designed to charge
your Electrafun nicad in just 20 minutes.
The charger connects to your car
cigarette lighter socket and features a
clockwork timer to start and stop the

If you are a newcomer to R/C flight
and have never flown a radio controlled model before; it is vital you
seek advice from an experienced
model pilot on where to fly and how to
fly.
Only fly in large open spaces that are
approved for R/C model flying and that
are away from people, animals, buildings, power lines, water or trees.
Only fly in bright, sunny conditions
where wind speed does not exceed 5
mph.
NEVER FLOWN R/C?
SEEK EXPERT
ADVICE FROM YOUR
LOCAL MODEL SHOP
GENERAL FLYING PROCEDURES AND TECHNIQUES

The following procedures are intended as a guide only. They are not a substitute for proper
model flight training conducted by an experienced model pilot.

If you have never flown R/C model aircraft you should consult your local model shop for information on local clubs/pilots who can help you learn to fly.
WARNING: IT IS DANGEROUS TO ATTEMPT TO FLY A MODEL AIRCRAFT WITHOUT PROPER TUITION
TRANSMITTER RANGE CHECK

Always range check your model before every flight.
Place your Electrafun on the ground
and collapse your transmitter aerial
completely. Walk away from your
model whilst operating the rudder
continuously. Ask a friend to watch
your model for you as you walk away.
The range check is OK if you can operate the rudder without interference
at a distance of 25 yards.
FREQUENCY CHECK
Always check your transmitter frequency with other pilots at the flying
field. The frequency number is printed
on the back of your transmitter.
IMPORTANT
Never operate your model if someone
is operating on the same frequency.
It will cause the model to crash and
spectators could be endangered.

FLYING TIPS




Use the controls gently. The right
stick controls the rudder and turns the
model left or right. Left rudder causes
the model to turn to the left and vice
versa.
The left stick controls the elevator. Pull
back on the stick to climb and push
forward on the stick to descend.
Use the trim controls on the transmitter to achieve straight and level
flight thereby using the minimum
amount of stick movement.
Use the throttle switch to cut the
motor and thereby reduce height to
descend or to set up for a landing approach.
If at any point you lose control of your
model, always cut the throttle so that
the model cannot travel too far.
BASIC FLYING — LAUNCHING
Use the frequency pennant tied to the
end of your transmitter aerial to check
the wind direction. Always hand
launch your model into wind.
IMPORTANT
Never attempt to launch any model
downwind. The model will not gain
enough speed to fly and will stall and
crash.

Get a friend to hold the model by the
fuselage below the wing.

Check that fingers and clothing are
well clear of the propeller

Operate the transmitter throttle switch
to check motor performance.

Check that the aircraft control surfaces operate in the correct direction
and by the correct amount of deflection.

Switch the throttle to the on position
and tell your assistant to launch the
model firmly into wind from shoulder
height perfectly straight and level.
A relatively hard throw is required to
launch the model to flying speed but
great care must be taken to ensure
the model is thrown dead straight and
horizontal.
The model should climb out level at an
angle of about 10-15 degrees. Use the
control sticks and trimmers to achieve
this.

Launch into wind
BASIC FLYING — LANDING
BASIC FLYING — TURNS
Once your model is at a safe height
(around 150 feet), practice turning to
the left and then to the right.

Left turn

Right turn
IMPORTANT
If you use too much rudder, the model
can enter a steeply descending flight
path known as a spiral dive. Release
the rudder immediately and apply a
small amount of up elevator to bring
the model back towards straight and
level flight. As the model regains level
flight; apply a small amount of down
elevator to kill off any tendency for the
model to climb.
To land the model, ensure that the
model is travelling downwind at
around 40 metres height and the
power is off. Allow the model to fly
past you by around 50 metres. Height
should be down to around 20 metres
at this point. Start a gentle left turn
and complete a 180 degree change of
course with the model flying into wind.
As the model descends to around 2
metres, apply gentle up elevator to
slow the model and bring it to a gentle
landing.
Disconnect the flight battery and turn
off the transmitter.

BASIC FLYING — AVOIDING STALLS

BASIC FLYING — DESCENT
Descend by cutting the power to the
motor and steering left or right to
your required target. You should not
need to use down elevator which will
serve just to increase the speed of the
model in a descent.

Ascent
Descent
Straight and level
An aircraft stalls when flying speed
is too low and the wing can no longer
generate enough lift to keep the aircraft flying.
A stall causes one wing to drop and
the aircraft to enter into a relatively
steep descending path. Correct a
stall by allowing the model to regain
flying speed and then use the rudder
to straighten up followed by a touch
of down elevator to stop any tendency
for the model to zoom up in a nose
high attitude.
Avoid the stall by never allowing your
aircraft to fly too slowly. Practice stall
recovery when you have plenty of
height and some flying experience.
It is important that every pilot should
know the limits of his aircraft.
FLYING ZONE

Try to keep the model within a defined area when flying as the further the model travels the
more difficult it is to see and therefore to control.
Keep the model in this area
