- Place the prepared wing on the fuselage, running the
aileron servo leads forward into the radio bay.
- Fix the wing to the fuselage using the M4 x 30 plastic
screw.
Fig. 27, connecting the aileron servos and battery
- Connect the aileron servos to the receiver using the Y-
lead.
- Place the battery in the radio bay for balancing,
but do
not connect it at this stage.
- Place the canopy on the fuselage again.
Fig. 28, balancing
- The Centre of Gravity (CG) should be in the range 50 to 60
mm back from the wing root leading edge. Mark this point
on both sides of the fuselage.
- Support the model at the marked points and allow it to
hang freely. The CG is correct when the model balances
level, with the nose inclined slightly down.
- Adjust the position of the flight battery if necessary.
- Mark the battery location in the fuselage, so that you can
be confident of replacing it in the same position after
removing it.
- Pack pieces of scrap foam round the battery, so that it
cannot shift in flight and alter the model’s balance.
Figs. 29 - 32, checking the working systems
Charge the flight battery.
Switch the transmitter on, and
move the throttle stick to
the “Motor stopped” position.
Place the fully charged flight battery in the fuselage and
connect it to the speed controller.
Check the
neutral position
of the control surfaces: adjust
the swivel pushrod connectors if necessary.
Place the model on the floor and stand behind it.
Check the direction of rotation of the servos:
Move the aileron stick to the right (a), and the right-hand
aileron should rise (a), the left-hand aileron fall (b).
Pull the elevator stick back towards you (c), and the trailing
edge of the elevators should rise (c).
Move the rudder stick to the right (e), and the rudder should
also deflect to the right (e).
If any function works the wrong way round, correct it using
the servo reverse facility for that channel on your transmit-
ter.
Adjust the control surface travels to those stated in Figs. 30
and 31.
Motor run
Hold the model in such a way that the propeller is free to
rotate.
Caution: whenever you are working on the model
(for maintenance, or making adjustments) do not stand in
front of the propeller, or in line with its rotational plane.
The same applies when launching the model.
Note that the propeller blades will open up suddenly when
the motor starts.
Check the motor’s direction of rotation: when viewed from
the front, the propeller must turn anti-clockwise. If that is
not the case (perhaps because you are using components
other than those we recommend), you can reverse it by
swapping over any two of the three motor wires.
Disconnect the battery from the speed controller first, and
only then switch the transmitter off.
The model is now ready for flying, as soon as you have
recharged the flight battery.
Test-flying, flying notes
- Please read the sections entitled “Routine pre-flight
checks” and “Flying the model” in the Safety Notes
before attempting to fly the model for the first time.
- For your first few flights please wait for a day with no
more than a gentle breeze.
The glider version should be
given a hand-glide to test its state of trim.
- A good flying site consists of a large, flat, open grassy
field, devoid of trees, fences, high-tension overhead
cables etc.
- Repeat the check of the working systems.
- The model is designed for hand-launching; ask an expe-
rienced friend to do the honours for you. He should be
capable of giving the model a reasonably strong, flat
launch.
- The model must be launched straight into any wind.
- With the motor running at full-throttle, give the aeroplane
a firm launch, directly into any breeze, with the fuselage
and wings level.
- Keep the “ASW 15” flying straight and level at first; don’t
turn the model while it is still close to the ground.
- Adjust the control surface trims if necessary, so that the
model flies straight with a reasonable rate of climb “hands
off”.
- Check the model’s response to control commands; you
may need to increase or reduce the control surface travels
after the first landing.
- Check the aeroplane’s stalling speed at a safe height.
- Keep the model’s speed well above the stall for the lan-
ding approach.
- If you needed to adjust the trims during the test-flight,
correct the pushrod length after the landing and return the
transmitter trims to centre, so that full trim travel is avai-
lable to both sides of centre for subsequent flights.
