[Translation of the original French comment]First rigid wing with wide diffusion. Very safe to fly, sink rate below 0.8m/s, glide ratio above 16, speed range from 32 to more than 110 km/h.
very easy to fly. handling at take off is typical rigid wing stuff: does not require any assistance in strong winds, cause on the wing that lifts up the spoiler will lift up too and will bring the wings level again without any pilot input. Very easy at take off. normal cruising speed is about 35km/h in thermals, 50 km/h straight. Very light in turns and very stable trajectory at speed hence excellent for (aero)towing. In thermals, its stability in roll requires sensitive pilot input to climb well. Not much affected by turbulences, only in pitch. Landing is easier than on a flex wing.
When folded, the weight and bulk can be problematic but splitting the wing in 2 halves helps.
