I know this post is 6 months old, but the ASG-29 is not an ASW-27 with long tips. It has changes to the airfoil, the wing fuselage junction, rudder and mixer. Sure it is based on the ASW-27 but it is a different glider, even in 15 meter configuration it has a different wing area than a 27.

In no way does Schleicher rest on their laurels, which why they have a history of winners in 15 meter, 18 meter and open. The new turbo ASG-29Es,, is the first with a starter. While Jonkers and Lange are and were a welcome addition in technology and competition both the Schleicher and Schempp factory continue to make great gliders that push the limits of production/design/ while still being a viable business.

Don't get me wrong - The ASG 29 is a great glider but its basically already
a 20 year old design. It's really just a 27 with some extra long tips.
