some new flyers new a quick visual on CG and incidence angle of attack and what they mean in actual practice
The new micro flyers such as the one ounce VAPOR can be used to easily demonstrate this
I learned it with paper gliders when I was a kid
the basics can't be skipped over if you really want to understand what is happening.
a text book full of how to's is fine - for some
but the new models DEMONSTRATE this and that is a learning approach which is much easier for some. The airfoil stuf is all well and fine but misses the basics.
