I have been pondering this question for the last few weeks, but haven't satified myself with an explaination yet. Most aerodynamics seem to make intutive sense to me, but this doesn't.
The test I am speaking of is when you put the sailplane into a 45 degree dive and see if it pulls up, flys neutral or tucks under. A page on how to do this can be found here: http://www.polecataero.com/articles/cg_art.shtml But this page doesn't explain why... to me it seems that a nose heavy glider should tuck not rise when the CG is in front of the average lift on the wing. Any help understanding this? Thanks -Richard RCSE-List facilities provided by Model Airplane News.
