LS-4 vs ASW-20
Hi,
I'd like to hear about the people who were able to compare the performance of an LS-4 with an ASW-20 in weak, average and/or strong conditions. Which climbs best? Which glides best? By what kind of advantage (is one glider really better than the other, or just average?) Overall, which is the best machine and is it a lot better or just slightly better? If one can point me out to some polar curves for both gliders, I'd be very happy. Thank you! |

These gliders are usually not compared, so it makes ask what you have in mind for your mission: contests, recreational flying, badges, or just curious? -- ----- change "netto" to "net" to email me directly Eric Greenwell Washington State USA |

Asbjorn put it well.
You might also have a preference for stiff (LS4) or floppy (ASW20) wings. I prefer stiff but bought an ASW20 for the performance per £/$ (still the best around) and the generally lower prices of the 20's anyway. If going for a 20 join: http://groups.yahoo.com/group/ASW20owners/ for more advice etc. There are already several comments about types etc. Regards Andy Henderson At 10:00 23 February 2004, Asbjorn Hojmark wrote: On Mon, 23 Feb 2004 00:04:15 -0500, 'AttentionLEcureuil' wrote: I'd like to hear about the people who were able to compare the performance of an LS-4 with an ASW-20 I don't think it makes all that much sense to compare them as they are in different classes.

These gliders are usually not compared, so it makes ask what you have in mind for your mission: contests, recreational flying, badges, or just curious? Yeah, I know about the differences and the FAI classes and I guess that is why it is very difficult to find a comparison on the internet. I'm interested in pure performance comparison, glider against glider in about the same conditions. The reason behind is that I'm looking to buy an ASW-20 and a guy at our club owns an LS-4. I am quite impressed by the LS-4 capabilities (I used to fly a SZD-41 Jantar Standard "against" the LS-4 and the LS-4 has a clear advantage in climb and cruise). I am wondering, pilot's skills aside, how will the ASW-20 stand-up against the very good LS-4 performance. So, I'd like to hear from people who have seen or experienced some cross-country flights with an LS-4 and an ASW-20 flying side by side. E.g. You own an LS-4 and your friend an ASW-20 and you go cross-country together every week-end. Does one clearly out climbs the other? Does one clearly pulls away in cruise? Does the "wind turn" for a glider or the other when the conditions become weaker or stronger (e.g. LS-4 performs better in less than 2kts and the ASW-20 gets the advantage when it increases to 4kts). Thanks a lot! |

If one can point me out to some polar curves for both gliders, I'd be very happy. Thank you! They are both fine gliders, but tHe USA handicap does list the ASW 20 with about 4% cross-country advantage over the LS4. The ASW 20 has a steeper, slower landing approach, due to it's flaps, and a softer ride in turbulent conditions, due to the more flexible wings. Those are two reasons I chose the 20 when I had one in the 80s. The ASW 20 B and C are preferable to the first model, as they have automatic elevator hook up and a disk brake; the C is preferable unless you really want the higher wing loading of the B model. I wouldn't chose between the LS4 and the 20 based on performance, as neither is at the top of it's FAI class anymore. In non-contest flying, it will be difficult to see any difference. I'd make the choice on the other qualities; primarily, I think the LS4 is an easier glider to fly, so would be a better choice for a club or lower time pilot. If the pilot is "experienced" then that isn't a factor, and he can choose based on the other features, like the short landing capability, etc. -- ----- change "netto" to "net" to email me directly Eric Greenwell Washington State USA |
