Side-by-side 2-seat ultralight airplane

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.

AEROTECH 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.

Efficiency and Aerodynamic

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. 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. At the low end of Risen’s speed envelope, generously dimensioned flaps give it a very low stall speed.
