Assembly & Operation Manual
INTRODUCTION
Thank you for purchasing Skymaster arf pro Sabre! We have put a lot of effort and time into this model.
We at Skymaster strive to be a market leader in the ARF— jet market. We were the first company to
produce ARF—jets in the world and we would like to continue being amongst the best. Although we
have made every effort that this model was fit for shipping, we would like you to inspect the contends
and call your nearest dealer immediately if any defects or missing parts are spotted! This manual will
allow you to duplicate the factory prototypes.
LIABILITY
You have acquired a kit, which can be assembled into a fully working R/C model when fitted out with
suitable accessories, as described in the instruction manual with the kit. However, as manufacturers, we
at Skymaster are not in a position to influence the way you build and operate your model, and we have
no control over the methods you use to install, operate and maintain the radio control system components. For this reason we are obliged to deny all liability for loss, damage or costs which are incurred
due to the incompetent or incorrect application and operation of our products, or which are connected
with such operation in any way. Unless otherwise prescribed by binding law, the obligation of the Skymaster company to pay compensation is excluded, regardless of the legal argument employed. This applies to personal injury, death, damage to buildings, loss of turnover and business, interruption of business or other direct and indirect consequent damages. In all circumstances our total liability is limited to
the amount which you actually paid for this model.
BY OPERATING THIS MODEL YOU ASSUME FULL RESPONSIBILITY FOR YOUR ACTIONS.
It is important to understand that Skymaster, is unable to monitor whether you follow the instructions
contained in this instruction manual regarding the construction, operation and maintenance of the aircraft, nor whether you install and use the radio control system correctly. For this reason we at Skymaster
are unable to guarantee, or provide, a contractual agreement with any individual or company that the
model you have made will function correctly and safely. You, as operator of the model, must rely upon
your own expertise and judgment in acquiring and operating this model.
WARNING
This ‘jet’ aircraft is a high-end product and can create an enormous risk for both pilot and spectators, if
not handled with care, and used according to the instructions. Make sure that you operate your Viper
according to the AMA rules, or those laws and regulations governing model flying in the country of use.
The engine, landing gear, servos, linkages and control surfaces have to be attached properly. Please
use only the recommended servos and accessories. Make sure that the ‘Centre of Gravity’ is located in
the recommended place. Use the nose heavy end of the CG range for your first flights. A tail heavy
plane can be an enormous danger for you and all spectators. Fix any weights, and heavy items like batteries, very securely into the plane. Make sure that the plane is secured properly when you start the engine. Have a helper hold your plane from the nose before you start the engine. Make sure that all spectators are far behind, or far in front, of the aircraft when running up the engine. Make sure that you
range check your R/C system thoroughly before the 1st flight. It is absolutely necessary to range check
your complete R/C installation first WITHOUT the engine running. Leave the transmitter antenna retracted, and check the distance you can walk before ‘fail-safe’ occurs. Then start the engine, run at about
half throttle and repeat this range check. Make sure that there is no range reduction before ‘fail-safe’
occurs. If the range with engine running is less then with the engine off, please DON’T FLY at that time.
Make sure that your wing spar tube is not damaged. Check that the anti-rotation dowels for the wings
are not loose. Check that the wing, stab, fin and nose retaining bolts are tight. Please don’t ignore our
warnings, or those provided by other manufacturers. They refer to things and processes which, if ignored, could result in permanent damage or fatal injury. Secure the plane before starting engine.

Assembly & Operation Manual
ARF Paint
The color finish on your Skymaster Sabre arf pro model was applied out of the mould.
We have used only the highest standard automotive paints to finish your model.
Should you damage the finish, Skymaster stock the color paint and hardener required
for the repair. A good automotive spray painter should also be able to mix and supply
the correct samples for repair.
If you have no experience in the use of these paints, it will be best to seek assistance.
Do not leave your model unprotected in the sun! always cover your model or park it in
the shade. Extreme temperatures will damage the paint!
Finishing Your All White SABRE ARF PRO
It is always best to fully assemble the model before painting. By doing so no damage
or glue prints will ruin the paint.
The all white model will have some release agent on the surfaces.
Use #1000 wet and dry paper to sand the entire model. Mould lines can be sanded
and filled using normal automotive fillers.
Please be extra careful when sanding near the hinge line! The hinges can easily be
damaged. When masking and painting please make sure the control surfaces are not
bend past 90—180 degrees extensively. This will cause the hinges to crack and may
cause flutter.
The rudder and clear canopy are not installed. It is best to install these components
after painting was done.

Assembly & Operation Manual
HANDLING & TRANSPORTING
Composite models are very light but strong. These characteristics do have a down side! It is
brittle.
Take care when handling your model. DO NOT ATTEMPT TO PICK UP AN FULLY FUELLED
MODEL BY THE LEADING EDGE BY YOURSELF! The leading edges will crack and delaminate. Full size jets have specially marked access points for the hooks of cranes!
Inspect your model before and after a rough landing. Make sure all parts are safe and sound.
Inspect model before and after transport. A sudden stop can easily cause an unnoticed dent!
The wings and tails are very flight worthy structures. They are light and extremely strong , however, they will dent if mishandled. Always support these structures on clean soft foam rubber.
LIVE HINGE
Skymaster utilize this system of hinging control surfaces because it is a very strong
hinge system and is accomplished at the factory.
Occasionally, because of climatic changes, the bottom surfaces may “catch” or interfere with control travel surface actuation. Should this happen, use a fine abrasive strip
to further bevel the L.E. of the control surface.
CAUTIONS: Do not apply any primer or paint to the underside of the main surface trailing edge.
Prior to each flight, check that the ailerons and elevators actuate properly, up and
down.
Inspect the live hinges on a regular basis. If some cracks occur please repair asap with
special hinge tape available from Skymaster or its dealers.

Tools and Adhesives
Assembly & Operation Manual
Tools etc:
This is a fairly quick and easy plane to build, for a jet model, not requiring difficult techniques or special equipment, but even the building of Skymaster aircraft requires some suitable tools! You will probably have all these
tools in your workshop anyway, but if not, they are available in all good hobby shops, or hardware stores like
"Home Depot" or similar.
1. Sharp knife (X-Acto or similar)
2. Allen key set (metric) 2.5mm, 3mm & 5mm
3. Sharp scissors, curved type for canopy
4. Pliers (various types)
5. Wrenches (metric)
6. Slotted and Phillips screwdrivers (various sizes)
7. Drills of various sizes
8. Battery drill and Dremel tool (or similar) with cutting discs, sanding tools and mills
9. Sandpaper (various grits), and/or Permagrit sanding tools (high quality - recommended)
10. Carpet, bubble wrap or soft cloth to cover your work bench (most important !)
11. Car wax polish (clear)
12. Paper masking tape
13. Denaturised alcohol, Acetone, or similar (for cleaning joints before gluing)
Adhesives:
Not all types of glues are suited to working with composite parts.
Here is a selection of what we normally use, and what we can truly
recommend. Please don’t use inferior quality glues - you will end up
with an inferior quality plane, that is not so strong or safe. Jet models
require good gluing techniques, due to the higher flying speeds, and
hence higher loads on many of the joints. We highly recommend that
you use a slow cured epoxy for gluing highly stressed joints, like the
hinges and control horns, into position and the most commonly used is
‘Aeropoxy’ (Bob Violett Models, USA). The self-mixing nozzles make
it easy to apply exactly the required amount, in exactly the right place, and
it will not run or flow onto places where you don’t want it! It takes about 1
- 2 hours to start to harden so it also gives plenty of time for accurate assembly. Finally it gives a superb bond on all fibreglass and wood surfaces. Of course there are many similar glues
available, and you can use you favorite type.
1. CA glue ‘Thin’ and ‘Thick’ types. We recommend ZAP, as this is a very high quality.
2. ZAP-O or Plasti-ZAP, odourless (for gluing the clear canopy)
3. 30 minute epoxy (stressed joints must be glued with 30 min and NOT 5 min epoxy).
4. Aeropoxy/Loctite Hysol 3462 or equivalent (optional, but highly recommended)
5. Epoxy laminating resin (12 - 24 hr cure) with hardener.
6. Milled glass fibre, for adding to slow epoxy for stronger joints.
7. Micro-balloons, for adding to epoxy for lightweight filling.
8. Thread-locking compound (Loctite, or equivalent)
At Skymaster we try our best to offer you a high quality kit,
with outstanding value-for money, and as complete as possible.
However, if you feel that some additional or different hardware
should be included, please feel free to let us know.
P-6
Assembly & Operation Manual
HEALTH
Use a mask (available at auto paint stores) to protect from inhaling the glass or carbon
fiber dust. Use this mask whenever you are sanding or cutting fiberglass or
carbon fiber materials. Use a charcoal filter paint mask (available at auto paint supply
stores) when spraying any primer or paint. Spray out of doors or in a properly vented
spray booth. Use safety glasses any time rotary tools, such as Dremel cut-off disc or
Perma-Grit cutters, are being used.
GENERAL ASSEMBLY TECHNIQUES
We recommend to wax the model before assembling. This will help protect the finish
from an epoxy finger print. Wax will not help for CA glues!
Extra glue, extra paint, extra resin will add up to a heavy model. Plan before you glue!
The glass cloth side of parts to glue, should be sanded with #80 grit paper for best
glue adhesion.
Support the fuselage on foam pads.
Skymaster makes every attempt to insure that the parts fit. However, due to manufacturing tolerances, some parts may fit a little tight. Always trial fit parts and adjust if
needed.
Only use high quality adhesives such as the ZAP products from Pacer Technology.
For extremely high stress areas we recommend “Aeropoxy.” It is the strongest and
best gripping adhesive we have found.
If fuel or grease are on the surface, first clean with acetone or thinners.
Clean off all excess glue—excess glue is excess weight.
Always check the outside skin of the model to look for any glue residue and remove it
with Acetone before it cures. “Aeropoxy” is tough to remove once it has thoroughly
cured.

Assembly & Operation Manual
Radio equipment
Failure to use the recommended servos, output arms, extensions, and hardware may result in a loss of control!
Throughout this manual we make use of various types of servos and radio equipment! We have used JR equipment
during the installation process. If you make use of
another manufacturer, please use equipment with similar specifications!
The Viper will require extension leads! Please use high quality extension leads. Make use of ceramic non ferrite
cores if leads exceeds 1 meter.
The trend nowadays is to use dual battery management systems and dual RX equipment. With the introduction of
2.4 Ghz even quad RX systems are considered as normal for a jet model.
Always center and install the correct output arms while on the bench, once the servo is in the aircraft access to the
servo arm screw is sometimes limited. The JR Matchbox makes this task very easy without using the complete
radio system on the work bench.
Do not save any money when buying radio equipment. The price of servo’s are far from the price of replacing the
entire model.
REMEMBER: The best equipment is only as good as the weakest link. Ask yourself if this servo or link or
lead etc is worthy of my trust to protect my very large investment...
Accessories
The full size F86 gear main gear doors are always closed. Accept when retracting. A special air or electronic sequencer is needed for this option.
1. 2 DS8511 servo’s for the elevator.
2. 1 DS8511 for rudder.
3. 2 DS8511 servo’s for ailerons
4. 2 DS8511 servo’s for flaps
5. 1 JR8511 steering servo.
6. 4 DS8401 servo’s for slats
7. 3 Standard JR577servos for Landing Gear, Door and Wheel Brake valves or check next line.
8. 1 Airpower EV5U valve + 1 x EV2U valve for landing gear + doors + brakes
9. 1 EV2U valve for speed brake
10. 1 EV2U valve for sliding canopy
11. 2 JR Matchbox for slats and flaps or Powerbox Royal with build in matchbox function.
12. Pneumatic support set for landing gear (air tubing, valves, Tee’s, fill valves, air tanks etc.)
13. Turbine motor, with thrust range between 16kg and 18kg, with ECU, fuel pump, battery and
solenoid valves, mounting strap etc. One of the common choices is the JetCat P160sx.
15. Fuel tubing, Hopper tank (or BVM UAT), festo fittings, fuel filters, fuel tube clamps etc.
16. Cable ties in various lengths. Cable management parts, Aluminum tape, safety clips etc.

Equipment installation is a personal venture. There is one golden rule: Do it as neat
and logical as possible! This will make faultfinding and service of components easier. The Sabre basically consist of 6 circuits!
1. Servo wires
2. Power cables
3. Data cables
4. Pneumatic pipes
5. Fuel pipes
6. RX cable / Satellite Receivers
Please try and separate these circuits as far as possible. It is advisable not to run RX
cables near any kind of electrical fields. Make all switches and filler valves and charging sockets easy accessible
The Sabre will come out tail heavy if you do not plan installation. It is very important
to install all equipment as far forward as possible.
I have installed 2 x RX + 2 X ECU batteries around inlet ring (photo 65). This is
weight of 1.2 kg together.
I have installed a UAT next to the nose gear retract. This will always be full of fuel
and will help with the final adjustment of CG.
Please wire the accessory tray outside aircraft. It is designed to slide and lock in
position. (note—tidy up wires unlike me :-))

Assembly & Operation Manual
BEFORE YOU FLY
It is assumed that the builder of this kit has acquired the basic skills and knowledge
necessary to make a safe and functional radio control installation into a model.
Therefore, these notes are intended only to assist that experience.
When inserting the main spar into wing, make sure it only enters the amount required.
If you can slide complete main spar into 1 half of wing, it means the stopper were removed. Please measure correct distance for main spar and secure spar so that it does
not slide more to one side than other. It must be symmetrical to both sides.
Travel adjust measured at root. Use Expo to suite your style.
1. Elevator 25mm 2. Rudder 25mm
3. Aileron 20mm 4. Flaps take off 35mm
5. Flaps landing 65mm 6. Slats 30mm
NOTE : Make sure flaps travel same. Flaps should be deployed in landing circuit only
below 90mph. On prototype flaps and slats were mixed together. If you require separate operation a separate switch will be needed.
CG 390mm –410mm from leading edge at root. Empty tanks, UAT full
and wheels down. The CG can be changed to best fit your flying
style. A forward position is safe and nose heavy configuration. .
WARNING: Do not move CG back unless you are experience
and have some feel of model before!
Weight Dry weight will be between 40 and 45 lbs depending equipment.
PSI 80—100 psi for pneumatic system
Power Make use of battery management system. Double up on batteries
and make sure all wired can carry current needed to operate.
TX RX Do a complete range check before flight. Do this with turbine
running. Follow manufacturers instructions.
Speed Set the maximum speed to 180mph! The prototype were tested
with Jetcat P-160 turbines. More powerful turbines require extra
care and extra reinforcing.
Timer A timer can safe your model. Get into the habit of programming
the timer.

Assembly & Operation Manual
Take-Off
Do some taxi tests before your flight! Make sure you are familiar with all settings and
make sure the model track straight on the ground without rudder input.
Choose a fine day for the maiden flight. Do not force a maiden flight!
Murphy will visit you!
Select take off flap or flight mode 1 and open throttle. Gently pull back on stick 50m
down the runway. Raise the flaps and gear at safe altitude and let the model sit on
rails.
Slow Flight
Most of the first flight should be utilized to get familiar with the slow speed flight characteristics. Select the flaps to the takeoff position; there should be no pitch change. Extend the gear and select full landing flaps; adjust the power to maintain level flight and
a speed of about 80—90mph.
Climb to a safe altitude and slow the model to the edge of a stall to know where that
edge is.
Landing
Fly a complete circuit before landing. Approach from the downwind side and lower the
LG. Fly a complete circuit getting use to the power required. On the next circuit lower
the flaps. If you have a headwind be very careful not to get below the power curve on
the downwind side. Do not use speed brakes for landing on maiden. When you are
happy and more experienced the speedbrakes will slow model down faster.
Align the model and use throttle to control the descent! The elevators will stay very active even at low speed. Flare the model just before touch down. Let the model roll out
and apply brakes.
Taxi back and do necessary adjustments to customize Sabre for your need!
We at Skymaster wish you many happy flights with your Sabre! Add some more scale
options like drop tanks etc. Before and after landing slide open canopy for extre realism. Add landing lights and machine guns and your Sabre will be just like real thing.
