RE: Northrop N9M Plans Availability
Don,
Thanks for your question. I am providing links to some websites that may help in understanding bell-shape lift distribution.
Reinhold Stadler's paper on bell-shaped lift distrbution: http://www.nurflugel.com/Nurflugel/P.../h_ca_01e.html
Also a graphic that illustrates the "bell-shape" of the spanload lift distribution:
http://www.nurflugel.com/Nurflugel/P.../falvy_19.html
If you want to modify your Klingburg wings for the bell-shaped span load, take a look at the next link. This will tell you how to modify your Klingberg and eliminate a lot of mathmatical work for you.
http://pr.erau.edu/~allenm/wing.html
You are going to have a "negative dihedral" at the tip of the wing panel using the Horten lift distribution, so you will need to add dihedral at the root of the panel.
I am thrilled to answer your questions, so don't be shy.
Jeff

N9M IMAA version
After three years of research and two years of developing flying prototypes, I am approximately two weeks away from publishing the first set of plans for the Northrop N9M. This first version is a twin-engine electric powered by two Speed 400 engines. Wingspan comes to just under 70". It can easily be converted to glow power. I have flown it both ways.
The second version is an IMAA legal version. Electric or glow powered...builders choice.
The third version is a fully scale N9M that may be used in scale competition.
And yes.... I may be producing plans for the 154" flying wing. But she is still in the flight testing phase so plans won't be released this calendar year.
Many of you have asked about the Ho229 that is in development. I am approximately 5 weeks away from the maiden flight. It uses two EDF's and has a 72" wingspan. Plans will not be available until Spring 2005.
More information will follow in about 7 days through a press release that will be distributed to the RC community (magazines, organizations and websites) . I'll be classified as a vendor and will conform to the RCUniverse.com vendor policies.
Thanks again to all for your interest and encouragement over the last few years.

OMG! Subscribed! "Everyone" has a Horten wing, but the Norcrafter birds are rare!
And I love 'stand apart' planes.
I can't wait until you start your N9M.
Any plans on making up the YB-35/49?

I've seen a lot of models flown and built on the various RC groups. Remember Horten designed many flying wings. Albeit the 229 is the most common one built that I have seen. I gave my son in law a short kit for christmas a few years ago.
Looking good so far Northrup!
