- Open the throttle (stick forward): the motor should now
run, and you should feel a strong flow of air exiting the tail
end of the model.
- Move the throttle stick back to the "Motor OFF" position.
- Disconnect the battery from the speed controller, then
switch the transmitter off.

- Stick the black plastic hatch cover in place again using
UHU-por; apply the adhesive only to the inside edges of
the cover.

- The next step is to check the model's balance: place the
flight battery in its compartment, but do not connect it.
- Mark the Centre of Gravity on both sides of the fuselage;
the position is stated in the photo.
- Support the model at the marked points and allow it to
hang freely. When correctly balanced the aeroplane will
remain horizontal, with the nose slightly down.
- If necessary, adjust the position of the flight battery to
achieve the correct CG.
- Mark the battery location in the fuselage, so that you can
be sure of positioning it correctly after recharging it.
- Pack scrap pieces of foam round the battery in its final
position, otherwise there is a danger of it shifting in flight
and altering the model's balance.
- Top up the flight battery, and the model is ready for its
first flight.

need to carry out maintenance work or a repair.

Assembly and operating instructions
AMX - Jet
This is the procedure for opening the fuselage:
- Open and remove the black plastic hatch cover.
- Remove the small fairings over the retaining screws.
- Undo the retaining screws.
- Remove the fuselage hatch.
- Disconnect the plugs and sockets: the speed controller
and / or the ducted fan unit can now be removed. Note
down the sequence of the wire colours.
- Reverse the procedure to re-install these items. The fair-
ings for the screws can be secured with a drop of contact
cement.
Test-flying, notes on flying the aeroplane
- Please read the sections entitled "Routine pre-flight
checks" and "Flying the model" in the Safety Notes
before attempting to fly the AMX - Jet for the first time.
- For the first flight you should wait for a day with no more
than a gentle breeze.
- A good flying site is a large, flat, open field. Keep well
away from trees, fences, high-tension overhead cables
and other potentially dangerous obstacles.
- Carry out a complete check of the working systems.
- We recommend that you ask an experienced modeller to
help you initially; he should be confident of giving the
model a fairly powerful hand-launch.
- The model must be launched directly into any wind
- Switch the motor on, and launch the aeroplane strongly
into the wind, with the fuselage and wings level.
- Allow the AMX - Jet to fly straight and level initially; don't
try to turn it when it is close to the ground.

- Adjust the trims if necessary so that the model settles into
a steady climb.
- Check the model's response to control commands from
the transmitter. You may need to increase or reduce the
control surface travels once the model is back on the
ground.
- Take the aeroplane up to a safe height and check its
stalling speed.
- Keep the speed well up on the landing approach to avoid
stalling.
- If you had to move the trims during the flight, correct the
mechanical linkages before flying again. This allows you
to re-centre the trims, so that full trim travel is available for
subsequent flights.
