I downloaded an excellent 2-page "trimming chart" a few weeks ago and have been trying to apply what it says not only to my actual RC aircraft but to an aircraft in my FS One simulator. So far the simulator is responding to CG changes as expected but my airplanes are not. Here's the situation.
The chart says one of the ways to check CG is to roll inverted and see if the pitch increases or decreases. It says if down elevator is required to hold level flight, move the CG aft.
A couple that I have say, "If a lot of down is required....."
There is one I've seen that says if no down is required that the airplane is tail heavy, and that is to be avoided.
