Question for all the aerodynamicists out there.

If a plane is flying, its wing must be generating lift. Does a wing generate lift at a zero degree angle of attack?

I thought that there must be some positive angle of attack in level flight. Am I wrong about this?

And if I am right, shouldn't the angle of attack be set to some small positive number?

Tom,

Interesting. The wing has wash out so different parts of the wing are at slightly different AOAs (think propagation of stall). The design has the longeron at zero degrees at cruise, flaps at reflex (think chord line from leading edge to flap TE). Even average angle of incidence doesn't work because of wing/flap design. Why not use zero, 1 or 2?

I am about to setup a g3x in my 360. I was wondering if anybody could tell me what the typical cruise angle of attack might be

Thanks
