sw51 Mustang  -  Overview

-> Detail Information


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


The ScaleWings sw51 Mustang is an absolute true-to-original ultralight replica of the legendary North American P-51 Mustang built to a scale of 1:1.43 (70%). The precise contours of the aircraft and the exact reproduction of the surface structures are what make the sw51 Mustang so compelling. Thousands of details of the original aircraft, such as rivets, screws, metal sheet joints and surface details of the original can be found on the ultralight 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 sw51 Mustang is manufactured in an intricate but extremely strong carbon fibre honeycomb sandwich construction. This guarantees minimal weight together with maximum strength.

The technology of the ScaleWings sw51 Mustang 



sw51 Mustang fl 18

sw51 Mustang fl 15

sw51 Mustang gr 31 

The sw51 Mustang is designed for high air speeds and aerobatics ( +6g / -3g).

The sw51 Mustang is offered both as an experimental aircraft with a MTOW of 2,646 lb / 1,200 kg and S-LSA with a MTOW of 1,323 lb / 600 kg (U.S. only). The Mustang will also be available as ultralight aircraft (EU) with a MTOW of 1,323 lb / 600 kg as soon as the MTOW for ultralight aircraft is raised to 1,323 lb / 600 kg.

An Experimental Exhibition is offered for the U.S. market.

The outer shell of the sw51 variants is identical but the 2,646 lb / 1.200 kg version has stronger structures and shells and conforms to the CS 23 load requirements. This enables stronger engines and higher speeds.

Engine types

sw51 Experimental

The standard engine for the experimental version will be the 300 hp Chevy LS ScaleWings edition of which a 600 hp version is also available.

The standard engine for the ultralight version is the ULPower 260iS (102 hp). ScaleWings also offers the whole range of Rotax engines from the 912 ULS (100 hp) up to the 915iS (141 hp). Speeds of approx. 280 km/h cane be reached with these propulsion units. The cruising speed is approx. 250 km/h.

Controller system in the standard version

sw51 Mustang ControllerA controller system with an extremely high safety standard has been developed to control the landing gear, landing flaps, and the electronic elevator, rudder and aileron trimming. This system is based on CANaerospace, a communication system developed for commercial aviation which has been tried-and-tested a thousand times over and also been published by NASA as a standard. All the functions can also be controlled from the rear seat with a second controller board.
Further details on the sw.Controller can be found under AeroTronics. 

Electrically retractable landing gear with emergency extension function

ScaleWings has developped a new electric drive for the retractable landing gear for the sw51 Mustang.

Landing flaps electronically controlled and monitored

sw51 Mustang gr 05 flapThe electronic control of the landing flaps enables a precise positioning and indication. The optional sw.Flinos enables the automatic positioning of the landing flaps according to the flight status. This reduces the pilot's workload and facilitates flying in difficult flight conditions.





Electronic elevator, rudder and aileron trimming

sw51 Mustang TrimBy default, the sw51 has a fly-by-wire trimming on all three axes controlled by the ScaleWings Controller.
The optional sw.Flinos offers a fully automatic trimming depending on engine power, speed, loading, attitude, altitude, etc.
Electronic trimming on all axes also enables attitude and course stabilization.




Electrically adjustable pedals 

The front pilot seat of the sw51 Mustang is equipped with electric rudder pedal adjustment as standard. As a result, the Mustang can be comfortably flown by pilots with a height of 165 to 195 cm. The electrical pedal adjustment is also available for the rear pilot seat as an option.
The optional sw.Flinos enables the pedal positions to be stored and subsequently automatically approached. This function is greatly appreciated by clubs, flight schools and charter companies.

Dual controls

The sw51 is equipped with dual controls as standard and can therefore also be flown from the rear pilot seat. The rear cockpit is provided with a minimal instrumentation as standard. Full instrumentation with an sw.Controller panel and sw.Flinos is also possible for the rear cockpit as an option.

Aerobatic fuel tanks

The two 50 litre Kevlar/Carbon safety tanks are located in the central wing area and can be easily removed for maintenance purposes. Aerobatic tanks which were specially developed for the Mustang and reliably supply the propulsion unit with fuel in any flight attitude are available for aerobatics.

The sw.AcroOil aerobatic oil supply system

ScaleWings has developed an innovative aerobatic oil supply system which reliably supplies the engine with oil in any flight attitude. Apart from the maintenance- and problem-free oil circulation ... -> read more

Integral engine cooling system

The cooling system was modified several times during flight testing, in order to be able to determine the best variant. The water and oil coolers as well as the cabin ventilation and heating are located directly behind the engine cowl in the lower fuselage area. The hot exhaust air is conducted directly downwards into the open air here.

As a result of this optimization, the large oil cooler shroud below the fuselage remains free and therefore generates hardly any air drag. 

Detatchable outer wings

The outer wing components (outside the landing gear) can be removed very easily. One person can assemble or disassemble the two outer wings within 5 min., whereby all connections (wing locks, aileron and flap connection, electrical and Pitot tube connection, etc.) are automatically disconnected ... -> read more

Elevator can be adjusted and disassembled

The sw51 Mustang can be deployed for a wide range of speeds, engines and take-off weights. A variable longitudinal dihedral has therefore been provided in the basic design. This enables subsequent tailoring to other deployment and equipment options. The elevator can be disassembled for easy replacement if damaged.

Cockpit equipment

sw51 Mustang de 19The sw51 cockpit panel with the analog instruments closely follows the original Mustang cockpit. The instrumentation is supplemented by the sw.Controller and the sw.Flinos as an option. There is also space for a 7-8 inch GPS, iPad mini or Android tablet. Details of the equipment can be found under Equipment and Prices.






Cockpit canopy

The cockpit canopy can be moved approx. 45 cm to the rear for taxiing and flight (max. 82 kt). The cockpit canopy can be opened sideways for easy entry and exit.






Luggage compartment

The sw51 Mustang has two luggage compartments. The front luggage compartment (between the engine compartment and cockpit) is for heavier luggage and the rear luggage compartment (behind the seats) for lighter luggage. The rear pilot seat can be folded forwards or removed completely from the aircraft for loading bulky pieces of luggage (e.g. golf bag, skis). An increased cargo space is available as an option. It includes an enlarged cargo space ranging from the behind the front pilot seat up to almost the rear landing gear. It contains a removable rear control stick and the lashing straps for the accomodation of (not to heavy) pieces of luggage. The area would offer itself as a place to sleep.

sw51 Mustang is made entirely from carbon

The entire aircraft as well as almost all the technical components are manufactured in a carbon technology patented by ScaleWings. This guarantees state-of-the-art standards, maximum strength with minimal weight and a decades-long service life.

AeroTrailer sideview

The sw.AeroTrailer was developed for the transport and “hangarage” of the sw51 Mustang. It is equipped with a special holding and swivelling mechanism, by means of which loading and unloading become child's play. A residential/office expansion kit will also be available for the sw.AeroTrailer from the end of 2017 to provide overnight, living or working accommodation at airfields, events or on the road. Further information can be found under AeroTrailer.




Worldwide transport in a sea container

The sw51 was developed by ScaleWings for the international market. With a transport frame for secure accommodation in a sea container or truck, the sw51 Mustang can be delivered anywhere in the world at a reasonable price in an almost ready-to-fly condition.

Flight tests

The sw51 Mustang has been undergoing flight testing with a Provisional Certificate of Airworthiness (PCA) / Permit to Fly (PTF) since September 2014. The extensive test flights have have confirmed the results of the first flights.

Test pilot Thomas Kreimeier certifies the sw51 Mustang excellent flight characteristics.

 Captain Thomas Kreimeier – (Test Pilot):

“Right from the start I had a very good feeling with the sw51 Mustang. The aircraft is very good and stable in the air. The control response is exceptionally good, similar to the new Comet S2. Both the take-off and landing do not impose particular requirements on the pilot.”
