Dear customer,
Congratulations on your choice of a
factory-assembled model aircraft from the jpower
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 power system
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.
The radio control system
To fly the KANATA you will need a radio control
system with at least four channels. 2.4GHz radios
systems are recommended, 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.
Glued joints, suitable adhesives
Foam safe epoxy is recommended and available
from most reputable model retail shops.
Trial-fit all parts “dry” before applying glue.
Follow the recommended curing time suggested
by the glue manufacturer. Allow the glue to fully
cure (harden) to the point where the joint can be
placed under stress.

Fig. 11-12 Checking Ailerons
- Check that the control surfaces respond to the
appropriate movements of the transmitter sticks. If
not,swap over the connectors at the receiver.
- Check the neutral position of the control
surfaces;you may need to screw the clevises in or
out to correct any discrepancy.
-Stand behind the model.
- check the direction of rotation of the servos:
-Move the aileron stick to the left (a), and the left
aileron(a) must rise up, the right aileron (b) fall down.

Fig. 17 Checking the power system
-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.

Fig. 19 Checking the models balance
-Place 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.
Fig. 20 Access to the ducted fan unit and
electronic speed controller
-The ducted fan unit is accessible from underneath,
if you need to carry out maintenance work or
repairs.
-Ensure that the wire colors match correctly.

- 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, and then switch the transmitter
off.
- The model is ready for flying once you have
recharged the battery.
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, devoid of trees, fences,
high-tension overhead cables etc.
- Repeat the check of all the working systems.
- Ask an experienced modeling 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 KANATA 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.
- We reserve the right to introduce technical
modifications and suggest that you check our
website for updates.
