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.


My -27 has been parked next to a -29 all week at Nephi. We've flown together all week - we are both flying with 15-meter tips ;-). The -29 has a slightly different taper break to accommodate the 18-meter tips/span so the tip chord doesn't get too small.This necessitated going from the two-taper planform of the -27 to a three-taper planform even is 15-meter configuration on the -29. I'm sure there was some tweaking of the airfoil to accompany the changes in taper. The rudder has a slightly longer chord to go with the longer span in 18-meter configuration. The fuselage sure looks identical and I can't pick up any differences in how the flaps and ailerons function - it's the usual Schleicher arrangement. I expect the certification authorities allow a number of minor modifications to a design to still qualify as a derivative, which saves a lot on certification for the things that didn't change.
