Yes I have his program and I not being an aeroengineer type still can use it and see some good results from different airfoils and his flap bender helps you locate the proper location for the flaps as well as the proper amount. The computer generated wind tunnel is the best. I picked an airfoil out for my scratch built v-22 osprey and when I found the one that gave me the most lift I found that it was the same airfoil that the first XV-3 that bell built.Which was like mine -==== heavy for the power plant .I still have not been able to make the transition to forward flight but the new wing did keep me up longer than the old ones .This year I am using some twisted blades that I hope will pull me thru the air fast enough for the wing to stay wingborne.
By the way John happened to pass through my area last year and stopped in for a visit and he is also a very nice young man to talk to and will help you with any aspect of engineering problems that you might go through.He also is an avid R/C pilot as well as a full scale aeroengineer.
hope this helps

Airfoil software
Well, moreover I am interested in software which will take random, known coordinates, off some old set of plans and convert to or search for a known airfoil. I do an awful lot of this. It would be helpful to take a tip and a root rib from an old plan and generate those in between.
As I see presently, I must hand sort through a few hundred airfoils to find one close enough. That takes too much time. It should be feasible to sort through the library of airfoils to find one (or two) which hits the shape necessary, then go through a correction process and smooth it up. I really need software which does a search for me, instead of it making me do the searching. It is not the intention to "Hop-Up" or alter the airfoil, but moreover to duplicate the original characteristics.

Designfoil

You are right, designfoil is only a computer wind tunnel and wing analzing program. I think what you are talking about could be done with the r/c design program that I also have ,called RcCad.It will do the root and tip rib ( you still have to do a little search for the right airfoil though )and then you can place ribs at any interval that you want in between and then print them out to paper along with the full size wing plans .You can also do the same for the fuse.You just insert a bmp or jpg of a 3 view drawing and move the rccad model lines to fit the 3 view and then press print and it makes the fuse plans and all the formers.
You can download a trial vesion at :
http://www.rccad.com
The price of the full program is only 49.95.I used it this last time on my scratch built V-22 osprey and really liked the way it worked.
Good luck

Sorry ,I mislead you.I was thinking about the RcCad program today at work and now I opened it up and find that it is Model Cad that you can put the airfoils in and it prints each rib for a tappered wing not RcCad.I guess that is why I have both programs.The RcCad is nice for the fuse formers and plans and the Model Cad works great on double tappered wings.You still have to look through a small library of airfoils and then load the symbol from the file and place it on the drawing where you want it.
What I did was to scan the tip and root ribs off the plans that I had and then saved them in the library under my name and then it was easy to find and use the airfoil that I wanted.
Hope this helps
