Another motor glider as successful as the ASH 31? There are 291 Ventus 2cM (including X variants) self launchers listed on the Rcawsey.co.uk site against 154 ASH 31s (although the latter list hadn't been updated recently). Also more self launching than turbo Ventus's are listed. I don't expect these figures to be entirely accurate on a spotter site but the point to the, for me very surprising, fact that SH are a major manufacturer of self launchers that are mostly registered into the large German market.
