[Aus-soaring] VMFG Video of Duo Discus Flight at Mt Beauty this Easter
Hi, The following you tube link is of a video taken yesterday at Mt Beauty. The video camera was mounted on the wing of our Duo Discus which was then winch launched on Mt Beauty Gliding clubs winch. The original footage is close to DVD quality but had to be compressed (and slightly shortened) in order to be put on the you tube site. http://www.youtube.com/watch?v=B-BL02Phibo Cheers, John Parncutt Victorian Motorless Flight Group ___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring

Re: [Aus-soaring] Swimmers getting helped by new surfaces
If swimmers wish to better there own performance, why don't they just swim in budgie smugglers and continue to inject steroids. Its a proven concept and works really well, just ask the Chinese. - Original Message - From: "Mike Borgelt" <[EMAIL PROTECTED]> To: "Discussion of issues relating to Soaring in Australia."

[Aus-soaring] 2 day NSW RASP Blipmaps forecasts now available ......
I have implemented 'Current+1' processing on the NSW Blipmaps - which means that in the evening after, say, 1800 you can see a forecast for tomorrow AND the day after... great for planning your weekend away. Saturday is looking good at this stage! Temporarily (probably permanently) at http://blipmap.walsys.net/UNI/univiewer.html (and only available via the Univiewer interface). The 'Current+1' forecast utilises AVN (low res) data, rather than the usual GFS (high res) data. See http://www.drjack.info/twiki/bin/view/RASPop/GFSvsAVN for more details. Thanks to David George for his assistance.
