Yes, and Diehl wing skins are longer than stock wings, but I don't think they lower the stall speed enough to get you into the LSA category, unless you build it very light. And I mean less than 500 #, and then, who knows. If you just want to lower the stall speed, add flaps.
See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2011 - KR Gathering in Mt. Vernon, Il - MVN There is a time for building and it never seems to end. Daniel R.
