I got the gen direct from the horses mouth. The tailplane can be set by lining up the T.E. with the top of the fuselage for the first flight. I don't know if this equates to 0 deg incidence. He was really helpful, by the way!

If you need a copy of the 1/7th scale Hawk instructions I can help you out.

If you are buying a built one there is not much in the instructions to help. I can easily post CG, control deflections and flying tips if that is all you need.
