The recommended C.G. is where the manufacturer feels the prospective buyer will have the most success and at the same time, they will like the characteristics of the plane.

A slightly nose heavy plane may need more "throws" to get the same amount of pitch movement as one that is not. (see Da Rock's and Nathan's comments ).

However a slightly nose heavy plane can also be easier to land. It depends in large part on the plane.

My Skybolt seems to be nose heavy to me, at the recommended C.G. IMHO for best in flight performance it needs to be much futher back than where the manual recommends for this plane.

However offsetting that, is that EVERY landing I make with this plane, I "grease" it in to a beautiful 3 point landing. Even in winds the plane makes me look GOOD.... so I'm tempted to leave it as is.

A tail heavy plane can be dangerous.
