Anyone here who know how I easily can find out how much a 10" longer nose (i.e. moving prop 10" fwd) impact longitudinal and directional stability of a SEP airplane? Say a RV-10.
Since your question is pretty generic and only uses an RV 10 as an example, I'd suggest that you post the question on http://www.homebuiltairplanes.com/forums/forum.php
You are likely to get a fine education on stability and aircraft design.

An older copy of "Airplane Performance, Stability and Control," by Perkins and Hage, contains an excellent and easy-to-use section that includes this sort of thing.
You'll need to assess the characteristics of the existing plane and compare those to the revised plane. In general, what you're describing will reduce the stability of the airplane, especially at higher power settings.
