Why?
Looks much like the ATEC Faeta NG, slightly slower in HP Cruise and considerably faster/higher Stall.
The Pipistrel Virus SW & Faeta have sub 30 knot stalls (about 8 Kn lower than the FK) - To me this is an important feature as:
It means that in a crash, the crew are likely to not only survive but walk away - minimal/nil injury.
Short Field capability is fantastic (not as good as a dedicated SF airfact)
Terrific glide (not quite as good as a dedicated glider) to get to a better landing ground/thermal if you wish/stooge around at 40-70 knots without fear of stalling
The Virus has Rotax two 80-100 hps options. The Faeta 80=100-115 hp options. Faeta 2-3 blade prop (ground adjust) and CS prop.
The Faeta comes in a T tail (the one I prefer) and a conventional (NG) tail.
The Virus comes in tail/nose wheel variants.
Not absolutely sure - both are available as, factory build, very advanced kits, multiple option, base to luxury fit out (all have the same performance)
