Dear customer,
Congratulations on your choice of a
factory-assembled model aircraft from the
J-POWER 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 Explorer EDFyou 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. 16 Photo shows the balancing weight.
- 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.

Fig. 19 Function test
- Check the channel assignment at the receiver, and if
necessary swap the plugs as necessary.
- Set the transmitter sticks and trims to centre.
- The control surfaces should now also be at centre (neutral).
Adjust the clevis where necessary.
- Check the direction of rotation of the servos.
- Stand behind the model. - When you move the rudder stick
to the right, the rudder should also deflect to the right.
- Pull the elevator stick back towards you, and the rear edge
of the elevator should rise.
- Moving the aileron stick to the right, you MUST check that
the trailing edge of the right aileron rises, the left aileron
should go down.
- If any function works the wrong way round, correct it using
the servo reverse facility on your transmitter.
- Set the control throw using the transmitter servo end point
adjustment function.
- The travels are measured at the inboard end of the control
surfaces.
- The stated control throws are just a guide for the first few
flights. You will probably need to adjust the actual settings
to suit your individual flying style.
- The Expo settings should also be adjusted to suit the pilot's
preference.

- 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 Explorer EDF 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.
