Default RE: Effect of incidence angles?

Wow, Jim! Thanks for the advice. Once the models start getting THAT big, making a balance stand becomes a serious matter! I'll definitely pick up an incidence meter this summer.

Sticking with strict scale construction, the Nieuport 11 looks to have zero tail incidence and about 2-3 degrees of upper wing incidence. The question is to what degree can a (very) scale model simply use the incidence angles of the real aircraft. The Flair Legionaire has a couple of degrees of positive incidence on the stab (created by an angle cut to the rear longerons). Not sure on the wing yet.

I'm going to have to do some research to figure out the CG point on the Nieuport 11's swept-back and slightly staggered wings. If anyone with a Proctor N.11 could give me a starting point that would be great. I prefer my models to be a bit nose heavy for that first flight. From experiements with RealFlight it's obvious that a plane can be seriously nose-heavy and still be manageable but just a bit tail-heavy can spell disaster on a maiden flight.

BTW, I thought we were supposed to balance the aircraft "dry" (with an empty tank).
