It's the logical evolution of the 4.5m². A kind of beast, but rather technical. No design problems to mention, it performs great. Very good handling for its size. The only (big) problem : luffs in a snap in gusty winds. Very efficient in laminar winds. In the buggy, performs best with a wide rear axle and lots of weight.
Spécifications : 5.35m spanwise, 5.5m² (AR=5.2). Profile : modified MH31 16%. 32 proportionnal cells, D-Ribs, twisted.
