I've learned a lot by asking questions here, so I'll add another one. I was wondering what the effects are from having the CG to far forward and to far back. do people adjust it for different style of flying or is it something that is always a constant?
Actually, a simple question that has simple answers.
Too far forward... The elevator is maxed out working to carry the load the CG creates being so far forward. Airplane is close to death from the elevator having no spare force available to do controlling as it's busting butt just fighting the bad CG.
Almost Too far aft... But still safely ahead of the Neutral point.... The elevator is extremely effective. Needs almost no deflection to give huge results. Tune the elevator throws to be minimal, and you got a flyable model. Unfortunately, no one does that and they all wind up with an airplane that scares the crap out of them.
Farther aft than that... As in at or behind the NP. No hope. The forces generated by the tail work with the lousy CG instead of against it. Unflyable model.
