Dear customer,
Congratulations on your choice of a
factory-assembled model aircraft from the jpower
Nano Warbirds range and thank you for placing
your trust in us.
The model can very quickly be completed ready to
fly. Please read right through these instructions
and the separate information sheets before
attempting to assemble and fly the model, as this
will make it much easier to complete the tasks
required.
All directions, such as “right-hand”, are as seen
from the tail of the model, looking forward.
Notes on the power system
Abrushless outrunner motor, propeller and spinner
are factory-installed.
The motor is connected to the speed controller,
ready to use, and the controller is correctly set up
at the factory.
To complete the power system all you have to do
is connect the LiPo flight battery.
The radio control system
For this model you require a radio control system
with at least four channels. We particularly
recommend 2.4 GHz systems.
The receiving system is powered by the speed
controller’s integral BEC system.
Before you check the model’s working systems,
set the control surfaces to neutral from the
transmitter (transmitter sticks and trims central).
Before operating the model always move the
throttle stick to the “motor stopped” position before
switching the transmitter on. Only then connect the
flight battery.
To switch off, first disconnect the flight pack from
the speed controller, and only then switch the
transmitter off.
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.
Kit contents
Fuselage with vertical fin, complete with motor,
speed controller and servos.

- Opening and closing the canopy:
The canopy is retained by the cowl at the front,
and by a tongue at the rear
- To open the canopy, slide it forward, raise it at
the rear and lift it off
- Reverse the procedure to replace the canopy.
- Congratulations, you have completed the
assembly process. We hope you enjoy flying your
new model!
Fig. 33 Balancing
- Place the canopy on the fuselage.
- Place the battery in the model of balancing; do not
connect it.
- Make 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 confident of replacing it in the same
position after removing it.

- Switch the transmitter on, and move the throttle
stick to the “Motor OFF” position. (Diagram MODE

- 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 adjustments 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. 38 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.

- 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 T-28 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.
