Congratulations on your choice of a
factory-assembled model aircraft from the

range and thank you for placing your
trust in us.
Very little preparation work is required to get this
model ready to fly. To operate your new model
safely it is important that you read through all of
the instructions and safety information included
with your model, before you fly it for the first time.
The illustrations in this manual show the Silver
version of the model with factory applied decals.

The model is powered by a brushless outrunner
motor and ducted fan, both of which are
factory-installed on the Ready-To-Fly version.
The motor is connected to the electronic speed
controller which is factory calibrated on the
Ready-To-Fly version. All that is required is to
charge the Li-Po battery, following the safety
instructions, and connect the battery to the
electronic speed controller .

To fly the Jas 39 you will need a radio control
system with at least four channels. 2.4GHz radios
systems are recommend ed , similar to the unit
included with our deluxe version.
The power for the receiver is drawn from the
electronic speed controller ’ s integral BEC system.
The electronic speed controller is located inside of
the fuselage, in front of the ducted fan.
When you wish to fly the model, always make sure
the transmitter is in the “ OFF ” position. Move the
throttle stick to the “ OFF ” position as well. Then
connect the flight battery to the electronic speed
controller .
Switch off in the reverse order: disconnect the
battery from the electronic speed controller first,
and then switch off the transmitter.

placed under stress.

- S tand behind the model.
- Check the direction of rotation of the servos:
- Move the aileron stick to the right (a), and the right aileron (a)
must rise up , the left aileron (b) fall down .
- Pull the elevator stick back towards you (c), and the trailing
edge of both elevators should rise (c) .
- If either function works in the wrong way, correct it using your
transmitter ’ s servo reverse facility for that channel.

- Hold the model securely.
- Remove any loose objects such as cloths, tools , etc from the
area in front of the model, as they could easily be sucked into
the ducted fan.
- Open the throttle (stick forward): the motor should now run,
and you should feel a strong air flow rushing out from the tail
end of the model.
- Move the throttle stick back to the “ Motor OFF ” position.
- Disconnect the battery from the electronic speed controller
and then switch the transmitter off.

- P lace the flight battery in its compartment, without
connecting .
- Mark the Centre of Gravity (CG) on both sides of the
fuselage; the position is shown in the photo.
- Support the model at the marked points and allow it to hang
freely. When correctly balanced the airplane 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.
- Pack scrap pieces of foam around the battery in its final
position, otherwise there is a danger of it shifting in flight
and altering the model ’ s balance.
- Charge the flight battery and the model is ready for flight.

- For the first flight you should wait for a relatively calm day with no more
than a gentle breeze.
- A good flying site is a large, flat, open field; 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 modeler to help you initially;
to give the model a fairly powerful hand-launch.
- The model must be launched directly into any existing wind .
- Switch the motor on, and launch the airplane strongly into the wind, with the
fuselage and wings level.
- Allow the Jas 39 Jet to fly straight and level initially , do not 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 airplane up to a safe height and check its stalling speed.
- Keep the speed well up on the landing approach to avoid stalling.
- If you ha d 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.
- We reserve the right to introduce technical modification s and suggest that
you check our website for updates .
