- Place the flight battery in the fuselage, but do not connect it at
this stage.
Fig. 8
Note: the ailerons should be connected to the receiver using a
Y-lead.
- Connecting the receiver: connect the servos and the speed
controller to the receiver. Refer to your radio control system
instructions for details of channel assignments and servo lead
polarity.
(the orange signal wire corresponds to the white wire used for
robbe-Futaba systems).

- Place the receiver in the fuselage and deploy the receiver
aerial(s).
Fig. 10, Balancing
- Place the canopy on the fuselage.
- Place the battery in the model for balancing; do not connect it.
- Mark the Centre of Gravity on both sides.
- Support the model at the marked C.G. and allow it to hang freely.
The model is correctly balanced when it hangs level, ideally 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 con-
fident of replacing it in the same position after removing it.
Figs. 11 and 12
- Charge the flight battery.
- Switch the transmitter on, and move the throttle stick to the
"motor off" end-point.
- Place the fully charged flight pack in the fuselage and connect it
to the speed controller. Wait until you hear the controller emit a
series of beeps.

Assembly and operating instructions
AT 6 Texan ARF
Figs. 13 and 14
- Check the channel assignment of the control surfaces, and swap
over the connectors at the receiver if necessary.
- Check the neutral position of the control surfaces. Make adjust-
ments to the clevises if necessary.
- Stand behind the model.
- Check the direction of rotation of the servos.
- When you move the aileron stick to the right (a), the right-hand
aileron (a) should rise, the left-hand aileron (b) fall.
- Pull the elevator stick back towards you (c), and the rear edge of
both elevators should rise (c).
- If either control surface function works the wrong way round,
correct it using your transmitter's servo reverse facility for that
function.
- Check that all the linkages are firmly fixed, but free-moving.
- We recommend that you set around 50% Expo on the aileron
and elevator functions.
Fig. 15, checking the electric power system
- Caution: position the throttle stick in such a way that the motor
cannot possibly start running.
- Switch the transmitter on, and connect the flight pack.
- Check the direction of rotation of the motor: when viewed from
the front, the output shaft must rotate anti-clockwise. If this is not
the case, perhaps because you are using components other than
those recommended, swap over any two motor wires to reverse
the direction of rotation.
- Note: whenever you are installing, adjusting or servicing the
power system, keep well clear of the rotational plane of
the propeller - injury hazard. Ensure also that nobody
stands in front of the model when the motor is running.
- First disconnect the battery from the speed controller, then
switch the transmitter off.
- The model is ready for flying once you have recharged the batte-
ry.

Test-flying, flying notes
- Read the sections in the Safety Notes entitled "Routine pre-
flight checks" and "Flying the model" before attempting
to fly the model for the first time.
- Advice on control surface travels
- The stated control surface travels are just a guide for the first few
flights. Every pilot will need to adjust the settings slightly to suit
his or her individual flying style. Exponential settings should also
be set to suit your personal preference.
- 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, devo-
id of trees, fences, high-tension overhead cables etc.
- Repeat the check of all the working systems.
- Ask an experienced modelling friend to hand-launch the aircraft
for you. He should be capable of giving the model a reasonably
strong, flat launch.
- The model must be launched directly 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.
- Allow the AT 6 Texan to fly straight ahead initially; don't initiate
turns 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 reaction to control inputs. If necessary, 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 landing
approach.
- If you needed to adjust the trims during the test-flight, correct the
length of the appropriate pushrod once the model is back on the
ground, then return the transmitter trims to centre so that full trim
travel is available to both sides of neutral for subsequent flights.
