Would(n't ) the tail volume (especially the horiz. ) have a large impact on the ability to move the C.G. aft to or perhaps behind the N.P.?
The larger the area of the stab. the greater the ability to remain stable in pitch as the C.G. moves aft, to or behind the N.P.?

The 3D types have large tail volumes. Makes for good control authority, and stability, and allows you to shift the C.G. further aft than perhaps a more "conventional" design...correct?


I added a little wt. to the tail of my Tribute "4D" 36 and now it (when I get it trimmed neutrally ) will dive just slightly whether upright or inverted. If I read the above posts correctly, that means I have the C.G. pretty close, right? (for this type of application )
