Angle of incidence question
Hey all...long time lurker, infrequent poster here.
Quick question (I didn't see a FAQ sticky anywhere): Building these airliners, is there a rule of thumb regarding angle of incidence for the wings and stab? I want to give the wings a few degrees positive...I know that, but not sure about the tail. I want to give it a little aircraft nose up trim (which would be a negative angle of incidence for the stab). Before I glue this is this the right thing to do?
Model is the KLM DC-9-15. Thanks for the help!

Hi GjFerg, I don't want to speak for other Builders here on RCG but I try and closely match the Main wing & stab Incidence angle of the plane I'm building as closely as possible.
I would say the DC-9 series has a Zero angle of Inc on the stab and a positive Up angle on the leading angle of edge of its wings between 2-4 degrees of incidence.
I hope this helps Sir!

The 2 degree angle of incidence is what I'm using on the Martin 4-0-4. The 4-0-4 was rather unusual; it had 3 degrees positive on the wing and a bit under 1 degrees positive on the horizontal stabilizer. The seasoned builders here recommended setting the stab to 0 and making the wing 2.
Going with that, hope it works!
