I thought I'd posted something here before but I guess I didn't.

Da man, asking an open ended question like this is like someone that can barely change engine oil asking for instructions to design a winning race car engine. It's just waaaayyyy too broad a topic in my books....

Speaking of books that's where I'd start. Along with some web searches on key words like aerodynamics, wing lift, lift coefficient, reynolds numbers and any of the dozens and dozens of terms you see in posts around here and elsewhere. I've done a few searches like this and was amazed at the large number of sites out there with interesting information, Java applets to show graphically what is so hard in words and other items.

And along with the actual shapes of the craft don't forget that the structure is just as important. Learning the how's and why's about structures is just as important as choosing the right wing area.

Read some books and web sites and study some model plans and then ask specific questions and you'll get more specific answers. As it is I wouldn't know where to start.
