    Yep - you get one chance before the vortex decays, however; that's all you need.

    I think this is possible if you can create a momentary Vortex on top the wing just before you touch down. Birds do it all the time when they land on a branch. Hang-gliders do it all the time (especially during spot landing contests). What can happen is you approach fairly fast above the stall...

    Thanks Topaz - Right on, now I totally agree with everything in your comments above (we see eye to eye). The Northrop wings are all a thing of great beauty. I don't agree with the radical taper ratios he used (affects handling) but from a total drag point of view, they are the cleanest thing I...

    Stephanie - if I can't trust you to accurately state the design origin of the Kasperwing (you still haven't retracted your link between the BKB and Kasperwing Ultralight in an earlier post) why should I trust you with my personal information?

    Topaz - you have no idea of my understanding of stability and control. I would suggest it is you who can't understand how a flying wing can maintain control in a vertical mush totally independant of forward airspeed (something the Kasperwing does). I may have mis-stated my comment about trim...

    Thanks Norm - nice video. Yes I already knew you can use flaps on a flying wing if properly sized and positioned. That's not the problem - I am not flying models and I am looking for a design that can carry 1-person or 2-people then back to one again without moving a bunch of lead weights around...

    Topaz - I totally disagree. Have You ever tried to design one that carries two people and actually flown it? Most people who say they they know about flying wings got their experience from models (simply different than full size aircraft). You can make any flying wing fly with a fixed payload...

    Norm - the question isn't how many machines did Kasper personally design by himself, rather how many of his ideas ended up in machines that were successful. I didn't take part in the BKB or Bekas design, only learned about them after the fact. The Bekas was crashed by Lynn Emrich who is/was a...

    Jim - In post #52 Stephanie states: The Ultralight was a successful design and very popular, I understand. I've talked to several people who flew it. Its design was based on the original BKB-1 concept: tailless, constant chord, slightly-swept wing, elevons and wing-tip rudder controls. I...

    [edited]When are you going to respond to my post and retract what you said said about the origin of the Kasperwing ultralight? signed: Vortexwing

    Stephanie - I have to agree with highflight. I am a Kasperwing owner who still flies and was there when the ultralight was designed and developed. I also knew Kasper and Grossruck and I can tell you with great assurance that the ultralight was not based on the BKB aerodynamically or control...
