Fig. 20, 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.
Fig. 21, the canopy
Place the canopy on the fuselage again.
Fig. 22, 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 position in the fuselage, so that you can be
confident of replacing it in the same place after removing it.
Pack pieces of scrap foam round the battery, so that it can-
not shift in flight and alter the model's balance.
The ASW 15 as a pure glider
Figs. 23 and 24
If you wish to fly the model as a glider, i.e. without the power
system, the propeller and spinner can simply be removed
and replaced with the glider nosecone.
Undo the screws holding the spinner in place, undo the pro-
peller nut and remove the propeller.
Undo the screws holding the motor in place, and remove
the motor, speed controller and flight battery.
Disconnect the speed controller from the receiver.
Fig. 25
Connect the receiver battery to the receiver using the switch
harness.
Fig. 26
Install the receiver battery and slide it forward into the nose.
The switch can be attached to the fuselage using Velcro
tape.
Assembly and operating instructions
ASW 15 ARF, ASW 15 RTF
Figs. 27 and 28
Place the glider nosecone on the model and fit the retaining
screws to secure it.
The model must now be re-balanced - see Fig. 22.
Figs. 29 - 32, checking the working systems
Charge the flight battery.
Switch the transmitter on, and move the throttle stick (fun-
ction 2) to the "Motor stopped" position.
Place the fully charged flight battery in the fuselage and
connect it to the speed controller. Wait until you hear a
series of beeps.
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 elevator 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.
Motor run
Hold the model in such a way that the propeller is free to
rotate. Do not stand in front of the propeller, or in line with
its rotational plane.
Note that the propeller blades will open up suddenly when
the motor starts.
Open the throttle (stick forward): the motor should now
start running.
Move the throttle stick back to the "Motor stopped" position.
Disconnect the battery from the speed controller first, and
only then switch the transmitter off.
Note: whenever you are working on the model, making
adjustments etc., keep well clear of the rotational plane of
the propeller - injury hazard.

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.
- 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.
