At 1:53: "Maximum weight of this glider when fully loaded on a World record with 2 pilots and water ballast is 1.2 tons"
I bet that's a test condition that the designer didn't envisage... Is the glider modified, or was that comment hyperbole or ignorance? -----Original Message----- From: aus-soaring-boun...@lists.internode.on.net [mailto:aus-soaring-boun...@lists.internode.on.net] On Behalf Of Mike Borgelt Sent: Wednesday, 4 May 2011 6:47 PM To: Discussion of issues relating to Soaring in Australia.

In the Schleicher gliders the landing flap transfers the lift to the inner part of the wing and the tips then hang down or at higher speeds could even lift downwards, hence the anhedral. Sure looks like flutter to me, initiated by the impulse of moving the lift outboard suddenly. This probably isn't a test condition that the designer envisaged. Fortunately the flutter was damped and ceased after a few oscillations.
