LS1c-d performance
The IGC HC of LS1c-d is 3 points lower than the LS1f (0.98-1.01). Why
is this differnece? The wings are the same, as I know. Does somebody has any experiences with LS1c-d performance, compared to LS1f, Std. Cirrus or ASW15? (Assuming more or less the same wingload). |

Idaflieg data, as availble in the Thomas book on glider design, supports the difference. This was the subject of review by the US handicap subcommittee a couple of years ago. US handicap difference is 2.4% which reflects maybe a liyyle difference in the analysis. The difference in "opinions" is worth 6 pt/day. FWIW UH |

Thanks, yes, this is the "theory", but I would be nice to get real-
life experiences. |

LS1c-d performance
LS1, LS1A-, LS1D are totally different gliders from LS1F, different
fueslage, different tail, cockpit even different wing construction, these can hardly be even considered to be all the same tim wrote in message ...

But the question is the real performance comparism between Ls1c-d and Ls1f, ASW15, Std. Cirrus. |

IMHO the LS1f should be consideribly better performer than ASW15 or Cirrus
and certainly handles far better than either of these and is more refined than earlier LS1 as well, Ealry LS1 would be more similar to these in both performance and construction to Cirrus and ASW15, ASW15B would be again a better glider than earlier ASW15, larger cockpit than earlier ASW15 also. tim "csonka istvan" wrote in message ...
