Fig. 93, checking the electric power system
- Caution: always move the transmitter stick to the idle
end-point before switching on, so that the motor cannot
burst into life unexpectedly.
- Switch the transmitter on, and connect the flight battery
to the speed controller.
- Check the direction of rotation of the motor: when viewed
from the front, the propeller shaft should rotate anti-
clockwise, as indicated by the arrow. If this is not the
case, e.g. if you are using components other than those
recommended, you can reverse the motor by swapping
over any two connections between the motor terminals
and the speed controller.
- Note: keep your fingers well clear of the rotational plane
of the propeller whenever you are working on the model
(assembly, adjustment, maintenance) - injury hazard.
Ensure that nobody stands in front of the model when
the motor is running.
Fig. 94, checking the control system
- Move the transmitter sticks and trims to the centre posi-
tion.
- The control surfaces should now be at centre. If this is not
the case, make corrections using your transmitter's servo
centre adjustment facility.
- Stand behind the model, and check that the control sur-
faces deflect in the correct "sense": move the rudder stick
to the right, and the rudder must also deflect to the right.
- Pull the elevator stick back towards you, and the trailing
edge of the elevator should rise.
- When you move the aileron stick to the right, the trailing
edge of the right-hand aileron should rise, the left-hand
aileron fall.
- If any of the control functions works the wrong way round,
reverse that channel at the transmitter using its servo
reverse facility.
Assembly and operating instructions
Charterle
- Use your transmitter's servo travel limit facility to adjust
the control surface travels as stated on the previous page.
Test-flying, flying notes
- Please read the sections in the Safety Notes entitled
"Routine pre-flight checks" and "Flying the model"
before attempting to fly the aeroplane for the first time.
- Wait for a day with as little wind as possible for test-flying
the model.
- The ideal flying site for initial test-flights is a large, flat
grassy field devoid of obstacles (trees, fences, high-ten-
sion overhead cables, etc.).
- Repeat the check of all the working systems.
- The model is designed for hand-launching; you will need
a friend to launch the model for you; he or she should be
capable of giving the aircraft a reasonably strong push
into the wind.
- The model must be launched exactly into any breeze.
- Switch the motor on, and give your assistant the signal to
launch the model firmly, directly into the breeze.
- Allow the machine to climb steadily, flying straight ahead.
Do not attempt to initiate a turn close to the ground.
- Adjust the transmitter trims if necessary to stop any
unwanted turning tendency.
- Check the model's response to control commands; you
may need to enlarge or reduce the travels once the model
has landed.
- Take the model up to a safe height and check the speed
at which it stalls.
- Keep the aeroplane's airspeed well above the stall speed
for the landing approach.
- The model can also be taken off from the ground. As for
hand-launching, all take-offs must be directly into wind.
11
- Carry out a few ground-roll experiments before attemp-
ting a take-off, so that you have some idea how the
aircraft behaves on the ground.
- Once you feel confident of the model's handling, point its
nose directly into wind.
Gradually advance the throttle to full power, allow the
model to gain flying speed on the ground, and apply gent-
le up-elevator to lift off; take care not to stall it at this
point. Adjust the trims immediately if necessary.
