Performer of innovative design,
efficiency and safety.


Our world speed record holder

Risen is an exceptional performer of innovative design, with unparalleled efficiency and safety, luxury interior, and top level avionics.



Risen is the all-carbon flying beauty in the picture above: a side-by-side 2-seat ultralight airplane with a wide cabin (123 cm) for pilot and passenger comfort, both enjoying a panoramic view from the 3 m2 motorized canopy, surrounded by gorgeous leather interior with Bose noise cancelling comfort headsets.


The choice of avionics for Risen mirrors its philosophy: excellence without compromise. The glass cockpit Dynon combines two 10” touch screens with one 7” central display. Additionally, a 2-axis autopilot and a computer for flap control are standard.


Exceptional safety for pilot and passenger is an integral part of Risen’s design philosophy. To this purpose, Risen features a ballistic parachute, anti-explosion and anti-fire fuel tanks, as well as inertial-reel seat and shoulder belts that can be locked for flight through turbulence. For additional protection, the cabin is surrounded by strong carbon reinforcement.


Risen is powered by the reliable Rotax 912 ULS engine. SEA has also developed a custom propeller which generates the optimal airflow around Risen’s fuselage and enables it to maintain an amazing continuous speed of 315 km/h.

Risen has been designed using tools and expertise generally found only in large aeronautical industries. Advanced fluid dynamics, in particular, is the secret behind Risen’s outstanding flight characteristics. Every detail as well as the overall shape of the aircraft were meticulously studied and optimized. The synergy of these optimizations resulted in an aircraft of spectacular efficiency, for example, with a glide ratio of 1:23 and speeds unheard of in any aircraft powered by the Rotax 912 engine. At the low end of Risen’s speed envelope, generously dimensioned flaps give it a very low stall speed. Careful design of all aerodynamic aspects assure reliable and desirable behaviour throughout its exceptionally large flight envelope. The meticulous attention to aerodynamic details behind Risen’s design is evident also from the choice of propeller: when propellers available on the market were found not to be optimal, SEA’s engineers developed a propeller design of their own which unlocked the full potential of this aircraft.

  SPEED (km/h) CONSUMPTION (lt/h) RANGE (km)
Long Range Cruise Speed 190 6,5 2360
55% Power Speed 230 9,5 1919
65% Power Speed 262 13 1562
75% Power Speed 290 17 1288
Max Continous Speed 312 21,5 1063


Risen is available in three different standard paint schemes and interior finishes: “Race”, “Sport”, and “Elegance”. Further customization is available, however, to tailor your aircraft to your own preferences.


Interior quality and comfort are one of the main goals of the project philosophy behind Risen. The wide cabin measuring 123 cm across, combined with the glider-like sculpted seats, allow pilot and passenger to enjoy full comfort even on very long flights (taking advantage of Risen’s range of 1288 km, at 290 km/h cruise speed).

The extra large canopy provides an almost 360o panoramic view, and the cabin is luxuriously appointed with carefully selected interior details and equipment.

The first production airplane debuted at the Aero Expo in Friedrichshafen (Germany) with leather and carbon interior fittings, but subsequent production is offered in 3 different styles: Race, Sport, and Elegance. Bose noise-cancelling headsets are included and provide a quiet space for relaxed attention and easy communications.

The motorized canopy, along with electric trim and flap operation, complete the Risen experience of exceptional comfort, functionality, and performance.


The simplified,
fixed gear alternative

With Siren SEA created a fixed-gear version of Risen, which will also conform to US LSA regulations. Besides the difference of the gear Siren has also a simplified flaps system with split flaps.



Risen is the all-carbon flying beauty in the picture above: a side-by-side 2-seat ultralight airplane with a wide cabin (123 cm) for pilot and passenger comfort, both enjoying a panoramic view from the 3 m2 motorized canopy, surrounded by gorgeous leather interior with Bose noise cancelling comfort headsets.


Siren is available with different ROTAX engines ranging from 80 to 115 hp and offered ready-to-fly with reduced minimum equipment at a lower entry-price. Like Risen the Siren has a full composite robust airframe structure with double carbon skin, sandwich foam and Epoxy resin technology. This offers optimum strength at a light weight. Another great advantage of the SEA airplanes: You can easily disassemble the tail and wings of your Siren to load it on a trailer or store it during the winter season.


The larger tyres, the light weight and the short landing and take-off distance make Siren interesting for all types of runways, even under difficult conditions. When it comes to efficiency Siren is at its top level. Even with regular tanks (2x 45 litres) it has a range of up to 2,340 km, so 1263 NM (including 30 minutes reserve) – this means you could go straight from Lugano to Saint Petersburg or from Miami to Montreal at a long range cruise speed of 180 km/h (97 kn).

For the cruise speed the optimized aerodynamics promise an outstanding performance of 250 to 265 km/h, so 135 to 143 knots at 75% (calculated by SEA simulation software). Depending on the engine we will guarantee a maximum continuous horizontal speed of 270 to 290 km/h, so 145 to 156 knots. For detailed information have a look at the download area.

First Demo

The first demo Siren was presented at AERO 2017 and will be finished this summer. More photos and videos are available in September. Siren is expected to become one of the fastest fixed-gear ultralights in the world. We are looking forward to test the performance in reality.

The demo Siren is for sale and can be delivered in September. Please contact the SEA sales under info@sea-avio.com for more information
