Design & performance goals for Diana 3

The Diana 3 was designed with the goal to have top performance in the FAI 18 metre class for sailplanes. 


The wing was design by professor Kubrynski and has a high aspect ratio over 30 and high lift. At low speed the Diana 3 has an enormous climb and yet at high speeds of 200 km/h a low descent of 1,4 m/s which will make the Diana 3 a tough competitor at competitions or just a great cross country glider / sailplane. 

Standard glider or SLG with FES-option

The Diana 3 can be ordered as a standard glider/racing sailplane or as a Self-Sustainer with the new safe and proven FES electric propulsion option from LZ Design. The FES-option makes your life safer and more secure when lift is weak and you need a push to gain some altitude to prevent unwanted landings outside the airport.
