●Caution!
Radio-controlled models, and especially model aircraft, are by no means
playthings in the usual sense of the term. Building and operating them safely
requires a certain level of technical competence and manual skill, together
with discipline and a responsible attitude at the flying field. Errors and
carelessness in building and flying the model can result in serious personal
injury and damage to property. Since we, as manufacturers, have no control
over the construction, maintenance and operation of our products, we are
obliged to take this opportunity to point out these hazards and to emphasise
your personal responsibility.
●Do not fly under the conditions below:
1.Wind strong enough to make the trees rustle.
2.A street with many trees or street lamps.
3.Close to high voltage electrical wires.
4.High Population density areas.
●Cautions for flying
Front lawns and parks make excellent flying areas. Make sure you have permission
to fly and follow safety guidelines set by local authorities. The calmer the wind, the
better!
●Note for Storage
Please disconnect the lipo packs when finished flying.
Do not press or crush the airplane when storing.
The best way to store is to hang the airplane to keep the control surface rigid.
Tools:
Scissors, balsa knife, combination pliers, screwdriver. quick-dry glue

not the case, follow the above illustrations applying the labels and/or the
decals to your plane by yourself.

Parts included in the packing

7 Canopy 1pc
8 Right servo arm protector 1pc
9 Left servo arm protector 1pc
10 Screw for EDF cover 1pc
11 Mounting screws for EDF cover 4pcs
12 Glass fiber stick for linking the wing

Assembly (Please pay more attention to those which have not been done at
factory.)
1) Stick the tailpieces in place as shown.
2) Glue the back of the rear rudder and the all related plastic parts as
well.

3) Connect right and left wing by using the grass fibre stick as shown in the
picture
4) Aiming at the pin holes, insert the pins.
5) Install the main wing to the bottom of the fuselage by using the mountin
g screws and pads provided.
6) Install the EDF in place onto the fuselage with 4pcs of mounting screws as

shown in the picture.
Note: Keep all wires in order during installation and never get them installed
reverse.
7) Place the cover of EDF and fasten it with due care by using the mounting
screws.
8) Following the illustrations install the servos seperately to both right and left
aileron , secure with the thrust steel wire , and then stick the cover onto the ar
m.
Note: Tuck the connecting wires of the servos into the slots. Replace with the
longer connecting wires if necessary.

9) Install the rear rudder servo as shown in the picture. ( Replace with the long
er connecting wires if necessary.)
10) Install the servo arm and the thrust steel wire as shown in the picture ,
level up the rear rudder and centre it in place.

11 Install receiver, ESC and battery, and power on, then debug before
fly.
12 After test, you can cover the equipment cabin canopy as picture shown.
.Recommended Flying Setup
Max servo travel of aileron: 25 degrees up and 25degrees down（20mm）
Max servo travel of elevator:15 degrees up and 15 degrees down（15mm）
Max servo travel of rudder: 15 degrees up and 15degrees down（15mm）
Setting the correct control surface travels is important if you wis h the model to res pond to t he
control commands in a balanced manner.
The t rav els should always be measured at the widest part of the control surface.
The c ont rol surf ac e throws are not crit ic al, and if you are unable to set the exact stated travels
using your transmitter’s adjustment facilities, that’s no problem. If the discrepancy is relatively
great, you will need to re-connect the linkage using a different hole at the horn or servo output arm.
If you intend to fly the model as a trainer, we recommend that you reduce the control surface
travels to about 50 - 60% of the stated values.

Setting the Centre of Gravity
Like any other aircraft, it mus t be balanc ed at a particular point in order to achieve stable flying
characteristics. Assemble your model ready to fly, and install the flight battery.
The Centre of Grav it y (CG) should be at a position of 84 mm away from wing leading edge, please
refer to attached picture.
Support the model at this position on two fingertips, and it should balance level. If not, you can
mov e the flight batt ery forward or aft to correct the balance point. Once the correct position is
found, mark the location of the flight pack inside the model t o ensure that it is always replac ed in
the same position.
Preparations for the first flight
Please wait for a day with as little breeze as possible for the model’s init ial test -f light . The evening
hours are often ideal for calm conditions.
Be sur e to carr y out a r ange check before the fir st fli ght, usi ng the procedur e descr ibed in your
RC system instructions. If you encounter a problem, please don’t risk a flight.
The fi rst fl ight . . .
If you are a beginner to model flying we strongly recommend.
that you ask an experienced model pilot to help you for the first few flights.
Hand-l aunching
Please don’t try unpowered test-glides with this model – the result is invariably a damaged
airframe. The Neptune should be hand-launched with the motor running at half-throttle, and
always pointing directly into wind.
Ask an experi enced modell er to hand-launch your aircraft for you.
The launcher shoul d run for ward for two or thr ee paces, then gi ve the machine a power ful
straight launch, with the wings and fuselage level. Use the controls to hold the model in a
steady, gentle climb - remember to keep the rate of ascent shallow and the airspeed high!
All ow the aer oplane to cli mb to a safe hei ght, then adj ust the tri ms on the tr ansmi tter until i t
flies in a perfectly straight line “hands off”. While the model is still at a safe altitude, throttle
back and tr y out the control s on the gl ide. Carry out a “dry run” landing approach at a safe
hei ght so that you ar e prepar ed for the r eal landi ng when the batter y r uns fl at.
Don’t try any ti ght tur ns at fi rst, and especi al ly not on the landing approach at l ow al ti tude. It i s
always better to land safely at some distance from you, than to force the model back to your
feet and risk a heavy landing.
38 Safety
Safety is the First Commandment when flying any model aircraft.
Thir d par ty i nsur ance should be consi der ed a basic essenti al . I f you j oin a model cl ub sui table
cover will usually be available through the organisation. It is your personal responsibility to
ensure that your insurance is adequate. Make it your job to keep your models and your radio
control system in perfect order at all times. Check the correct charging procedure for the
batter ies you are using. Make use of al l sensi ble safety systems and pr ecauti ons whi ch ar e
advised for your system. An excellent source of practical accessories is the SUPER-E main
catalogue, as our products are designed and manufactured exclusively by practising modellers
for other practising modellers.
Always fly with a responsi bl e attitude. You may thi nk that fl yi ng l ow over other peopl e’ s heads
is proof of your piloting skill; others know better. The real expert does not need to prove
himsel f i n such chil di sh ways. Let other pilots know that thi s is what you think too.
Always fly in such a way that you do not endanger your self or other s. Bear i n mi nd that even the
best RC system i n the wor l d is subject to outsi de inter fer ence. No matter how many year s of
accident-free flying you have under your belt, you have no idea what will happen in the next
minute.
