  for the privat recreational aviation.

Headquarter
ScaleWings has its headquarter in Strasswalchen (Austria), about 30 km northeast of the city of
Salzburg, where development and sales are located. This is also the place where the SW-51 Mustang
(ultralight) was developed in the years 2011 – 2017.
In 2017 ScaleWings investors enabled ScaleWings to develop the Experimental version of the SW-51
Mustang in cooperation with an aviation certified (DOA) and renowned engineering company
to meet the requirements for the 1200 kg experimental version according to the CS-23 regulations.

The SW-51 Mustang – the innovative legend !

Never before has an historical aircraft been successfully recreated as a light, ultralight and
experimental aircraft in such detail.

The ScaleWings SW-51 Mustang is an absolute true-to-original replica of the legendary North
American P-51 Mustang built to a scale of 70%. The precise contours of the aircraft and the exact
reproduction of the surface structures make the SW-51 Mustang so compelling. Thousands of details
of the original P-51, such as rivets, screws, metal sheet joints and surface details of the original can
be found on the SW-51 Mustang.

In order to be able to
replicate the same
true-to-the-original
surface over and
over again,
ScaleWings has
developed a new
manufacturing
technology. The SW-
51 Mustang is
manufactured in an
intricate but
extremely strong
carbon fibre
honeycomb sandwich
construction. This
guarantees minimal
weight together with
maximum strength.

SW-51 Mustang - ScaleWings
Versions

Quick-build kit for amateur aircraft builders
The quick-build kit is designed for a maximum take-off mass (MTOM) of 1,200 kg or 2,646 lbs and
engines up to 600 hp (441 kW).
Due to the special design, the building time can be limited to appr. 600 hours for an average amateur
aircraft builder. In order to maximize quality and safety, ScaleWings and its distribution partners offer
an extensive building support.

                    Build your own SW-51 Mustang with the help of experts !

Using cutting-edge technologies and an innovative streamlining of planning, manufacturing and
assembling processes we managed to design a Factory Assisted Build program that reduces the usual
time of Aircraft Kit Building by more than 75%.

The tailor-made “Build Your Legend” program offers professional building assistance in line with
the FAA Major Portion Rule (51 % Rule), bringing the goal of completing your own Kit Built Aircraft
within the reach of only 3 to 4 weeks. Appreciate of the joy of building your own aircraft in minimum
time while gaining full understanding of the processes and components involved in manufacturing your
own Legend. Knowing each and every detail of your SW-51 Mustang is your safety gain and brings you
the comfort to fly this aircraft to its maximum performance.
We invite you to visit our production site in Krosno, Poland.

Ready-to-fly ultralight aircraft (EU)
Europe has paved the way for an increase of MTOM for ultralight aircraft up to 600 kg or 1,323 lb. As
most European member states will pick up the possibility to allow a MTOM of 600 kg or 1,323 lb for
ultralight aircraft, the SW-51 Mustang is also offered as an ultralight aircraft.

Ready-to-fly Light Sport Aircraft S-LSA (USA)
From beginning of 2019 the S-LSA version will be available in the U.S. Due to the U.S. regulations it
has no retractable landing gear, a fixed pitch propeller and its maximum speed it limited to 120 kts.

All versions
are produced in the same
moulds and are visually
identical. They only only by
the
strength of structures and
shells. The structures and
shells of the experimental
version are considerably
stronger and stiffer to
enable the envisioned
engine power and speeds

For details please consult
the section Specifications.

Rotax prohibits aerobatics with their engines. So it´s not allowed to fly attitudes of more than
60° bank and +/- 30° pitch. Rotax engines can therefore not be uses for aerobatics. The ScaleWings
AcroOil system is hence not available for Rotax engines.

Rotax prohibits aerobatics with their engines.
So it´s not allowed to fly attitudes of more than 60°
bank and +/- 30° pitch. Rotax engines can therefore
not be uses for aerobatics. The ScaleWings AcroOil system is hence not available for Rotax engines.

Flight tests
The SW-51 completed the first part of the flight test in September 2014 with very good results.

Test pilot Thomas Kreimeier attested to the excellent flight characteristics of the sw51 Mustang.

Captain Thomas Kreimeier – (Test Pilot):
“I had a very good feeling with the Mustang right from the start. The aircraft is comfortable to fly,
stable but shows at the same and exceptional responsiveness, similar to the Comet S2. Both the take-
off and landing do not require any specific demands to on the pilot.”

Cockpit panels

Front cockpit panel
The following picture shows the fully equipped front cockpit panel. It is equipped and designed to suit
our customers individual wishes. With regard to navigation, there are tablet solutions as well as
complete packages for Garmin, Dynon and Flybox-Oblo including the associated autopilot equipment
available.

Rear cockpit panel
The rear cockpit panel is equipped and designed to suit our customers individual wishes.

Tablet solutions
Due to the popularity of tablet computers in the cockpit, ScaleWings offers tablet solutions for iPad
mini 4 and Samsung Tab S2 8”. These holders fit the tablets harmoniously into the panel. The tablet
holders include ventilation and heating to keep the tablets within their operational temperature range.
The tablets can be taken out at the push of a button and taken home for flight planning. The standard
side pocket of the SW-51 has place for a second tablet which eliminates the need to carry paper-
based documents.

FLINOS - Flight Information and Operating System

The FLINOS is the central module for the control of the retractable landing gear, the landing gear
doors and the flaps of the SW-51 Mustang. The FLINOS display also informs about the position of the
trim rudder for ailerons, elevators and rudders.
The main control functions are performed by individual high safety modules.

FLINOS – standard control panel

Left: Flaps
Tipping the selector switch up or down selects the next flaps position. The actual position of the flaps
is indicated through the four LEDs.
Center: LED trim tab position indicators for the three-axis trim.
Right: Landing gear control
Tipping the selector switch up or down actuates the landing gear drive. A control logic operates
landing gear and landing gear door drives and their sequential order.

For additional comfort, the FLINOS can be upgraded with an optional Linux controller board and
software modules which can be purchased separately installed.

FLINOS Linux control panel
As an extension of the FLINOS basic version the Linux computer offers the pilot a whole range of
modules to choose from:
 -   monitoring of landing gear, landing gear doors, flaps
 -   monitoring of wing connections
 -   fuel and energy monitoring (incl. sensors and wiring)
 -   engine monitoring (incl. EGT & CHT sensors and wiring)

The FLINOS Linux control panel offers a color display. Depending on the installed software modules,
the pilot can select from a variety of information, such as trim tab positions, engine data, etc.
The FLINOS Linux control panel allows to install a second FLINOS control panel in the rear pilot's seat
which replicates all functions and information from the main FLINOS Linux control panel.

FLINOS – control unit
The FLINOS control unit is the core of FLINOS. It operates the FLINOS control panels. Located in the
center console, it is the terminal for all prefabricated and tested wiring harnesses which are connected
to the control unit by screwed connectors. The multiple cable connections are made by electronic
boards of highest quality which eliminates manual wiring in the fuselage. The FLINOS control unit also
houses all circuit breakers.

The Linux computer multiplies the options as the computer unit handles all communication protocols
(Ethernet, CanBUS, CANAerospace, Video, Audio, etc.) and opens all doors for future developments.

The FLINOS is a joint development of ScaleWings and a well-known company in the field of safety
electronics. It goes without saying that all components are subject to strict safety tests.

"FLINOS" is a registered trademark of the ScaleWings group of companies.

Retractable landing gear

Main landing gear
Landing gear leg
The SW-51 Mustang is equipped as a
standard with a sturdy retractable
landing gear. The landing gear legs are
made of high-strength steel and
equipped with gas-spring shock
absorbers with a travel of 200 mm (8
in.) which take over both, suspension
and damping. This results in a
progressive suspension at the end
position range and at the same time
provides damping already from the first
millimeter of deflection.

Wheel
The SW-51 Mustang wheel consists of a two rim halves made
of high-strength aluminum which replicates the original. In
combination with the aviation tire (19.5 x 8 ") it looks
deceptively similar to the original tire of the P-51.

Brakes
The SW-51 is equipped with Beringer® high-quality disc
brakes. By default the SW-51 is equipped with toe brakes for
the pilot seat only. Toe brakes for the rear seat are available.

Optionally a differential hand brake can be selected for both
seats.
Function: At a defined deflection of the rudder the brake in the
outside of the turn is released. In conjunction with the
unlockable tail wheel the plane can be rotated on the spot.

Landing gear drive
The new landing gear drive enables the locking of the landing gear both retracted and extended
without locking lever or locking pin. This guarantees an accurate long-lasting locking without any
jamming.
In case of a mechanical or electrical failure the integrated emergency extension system triggered from
the pilot seat ensures the unlocking, extension and locking of the landing gear.

Main gear doors
A slightly modified drive is used for the operation of the inner main landing gear doors keeping the
advantages of the main landing gear drive.

Tail gear
The tail gear is a lightweight steel construction using the slightly modified electric drive from the main
landing gear.
The tailwheel is connected to the rudder and can be decoupled to turn the SW-51 Mustang on the
spot. It can be rotated around 360° which eases hangaring.

The tailwheel landing gear doors are driven from the tail wheel drive.

Flaps
The four-part flaps are driven through threaded spindles by one electric motor via a single tooth belt.
As a result, the exact same landing flap movement is reliably guaranteed on both sides of the wing.

Trim
Electric trim on all controls is a standard feature. The aileron and elevator trim tabs are operated each
by a separate trim motor. In case of a malfunction of one trim motor the runaway can be
compensated by the second.
Aileron and elevator trim is controlled by a four way hat switch on the stick grip. Rudder trim by a
rocker switch at the front side of the throttle grip.

Easy removable outer wings
The outer wings (disconnecting line outside the landing gear) can be easily removed. One person only
needs five minutes to attach or detach the outer wings with all connections (wing locks, aileron and
flap connection, electrical connections, pitot tube hose, fuel lines from outer to center wing)
connecting or disconnecting using a single lever.

The optional FLINOS Linux pack monitors all connections electronically (wing locks, aileron and flap
connection, electrical connections, pitot tube hose, fuel lines from outer to center wing).

Outer wings removed, the SW-51 Mustang only needs 280 x 690 cm (9 x 23 ft.) hangar space.

GALAXY parachute rescue system
All SW-51 Mustang versions are prepared for the installation of ballistic rescue system. ScaleWings
relies on GALAXY® which has years of experience. GALAXY has customized the parachute pack to fit
into the SW-51 fuselage.
In case of emergency, the parachute can be triggered from both seats. Within only a few seconds, the
aircraft and its crew glide safely back to earth on a parachute.

Carbon – Kevlar – safety fuselage shell
The safety of our customers is of paramount importance for ScaleWings. Therefore the cockpit section
of SW-51 Mustang fuselageis equipped with an inner safety shell made of carbon/Kevlar-fibre. This
safety shell enhances in the same time the strength of the fuselage..

The above picture shows the
laminated carbon-Kevlar shell
before vacuum compression.

The safety shell enhances the
historic metal look in the cockpit.

Seats and pedal
adjustment
The carbon-Kevlar seats combine high stability with low weight and splinter protection for pilot and
passenger. The seats can be moved 120 mm forward up and backwards down and ensure a
comfortable seating position for any pilot.
The rudder pedals are also adjustable (+/- 80 mm).
This adjustment combination allows for an ergonomic seating for pilots between 160 and 200 cm (5 ft
3 in. and 6 ft 7 in.).

The optional electric seat adjustment allows an easy seat adjustment at any time even during flight.

The seats can be raised by the optional seat lift which raises the seat by 200 mm and offers even
more entry and exit comfort.

Dual stick control
Dual control comes as a standard and allows the SW-51 to be piloted from the both seats. (Attention:
only with a pilot in the front seat!).
As a standard the rear cockpit is equipped with a minimal instrumentation.
Optionally, the rear cockpit can get a full instrumentation and the FLINOS.

Fuel tanks
Aerobatic main fuel tanks
The two 50 liter (13 USGal) Kevlar safety tanks located in the center wing, are easy to remove for
maintenance. By default, these tanks are designed for aerobatics and reliably provide the engine with
fuel in all flight attitudes.

Auxiliary tanks
The outer wings can be equipped with auxiliary tanks. These are membrane tanks installed in front
and the rear side of the main spar. Fuel transfer from the outer wing tanks to the main center wing
tanks is done through electric pumps.

Fuel gauges
Four fuel gauges indicate the fuel level. The fuel transfer switch is placed next to the gauges. Pushing
the button initiates and stops the fuel transfer. The fuel transfer is automatically stopped when the
main tanks are full or if the outer wing tanks are empty.

ScaleWings AcroOil aerobatic oil supply system
ScaleWings has developed a novel aerobatic oil supply system (AcroOil) which reliably supplies the
engine with oil in all flight attitudes. This patented aerobatic oil supply system integrates not only the
maintenance free and reliable oil routing but guarantees that not oil escapes into the environment
during aerobatics.

Silencer and exhaust system
The engine packages also include the silencer and the sixfold exhaust pipes made of stainless steel on
each side of the aircraft.

Cabin ventilation and heating
The fresh air is taken at the front air inlet behind the propeller. Two vents in the instrument panels
and one in the center console assure good aeration of the cockpit. Additional vents in the windshield
frame prevent the windshield from fogging.
Cabin heating is provided through heat exchangers around the silencer but for safety reasons, the hot
air duct is not directly connected to the silencer wall.
Hot and cold air can be controlled separately through to buttons in the center console.

Standard and additional equipment
Please consult the attached Equipment & Option List.

Canopy
For taxiing the canopy can be slided 45 cm backwards. In the rear position the canopy can be
swiveled to the right side for a comfortable entry and exit.
By pressing the emergency release, the canopy is jettisoned rearwards.

Paint and aluminium look
The ready-to-fly ultralight version of the SW-51 will be painted to customer requirements WITHOUT
extra charge. Giving your Mustang a unique appearance.

An optional look of polished aluminium is available. It is permanently protected and needs no
polishing.

We can also give
your Mustang a
weathering effect
(artificial aging) in
the intensity you
wish.
Historic maintenance
and service labels
are available as an
option.

We offer to realize
this special surface
treatment for your
Experimental
Mustang in our plant
in Krosno.

Luggage compartments
The SW-51 Mustang has wo luggage compartments. One in the front (between firewall and cockpit)
and one in the rear (behind the rear seat). To load bulky items (e.g. golf bag, skis) the rear seat can
be folded forward or removed completely. Both luggage compartments are equipped with lashing eyes
to secure items.

Both control sticks are removable. Removing the rear seat and the rear stick enlarges the space to a
“sleeping place on tour.”

Worldwide container transport
The SW-51 Mustang was developed for the international market. Therefore, ScaleWings offers a
transport frame for safe accommodation in containers or on trucks or trailers. This allows the SW-51
Mustang to be delivered to virtually anywhere in the world at low cost, almost ready to fly.

Once arrived at the destination, the SW-51 is swiveled from the 45° position on the transport frame to
the horizontal position. The landing gear extracted, the SW-51 can be rolled from the transport frame.
Mounting the propeller and the outer wings attached you only need fuel to take-off.

It is just as easy to ship the Mustang (e.g. for painting or completion and repair work) to our plant in
Krosno.

Maintenance
Minimal maintenance was one of the development goals for the SW-51 Mustang. This has been
achieved, except the engine maintenance.
The SW-51 maintenance manual is essentially just an inspection manual.

Load tests
Using carbon fiber for both the shells and the entire structure in a special technology realizes a very
favorable weight-to-strength ratio thus enabling a higher payload.
In 2014, the SW-51 has successfully completed the load tests for ultralight aircraft – with impressive
results – as shown in the following picture. By far above the requirements.

Safety of its customers is paramount for ScaleWings. Therefore, not effort was spared to offer our
customers the highest safety standard.
The new software
controlled hydraulic
test rig at our location
Krosno enables
ScaleWings to perform
comprehensive load
tests, both for the
1,200 kg (2,646 lb) kit
version and the 600 kg
