Where is the CG?

It's been mentioned by a couple of us because it matters.

When an airplane trimmed for level flight climbs with an increase in power, and dives with a decrease in power it very often has the CG too far forward. It can be other things as well, but a too far forward CG is a good bet. The airplane is lugging around a CG that can be handled by the tail at cruise with the help of the engine. The pitch is balanced at that speed, but when the airplane speeds up, the tail trim works better with the increased airspeed. And that tail that has been pushing down some at cruise speed now pushes down even more. And the airplane starts to pitch more and more up. So now you slow it down below the cruise speed and now that horizontal tail trim doesn't work as well at the slower airspeed. And the CG simply pushes the nose down.

The tail on that airplane really looks marginal for the job it's being asked to do. When they're too small the CG range is very narrow. The CG range is where the CG can be, front to back, on the wing and the airplane fly ok. The range can be increased by increasing the size of the tail or moving the tail farther back. Or you can simply plug the numbers into that CG Locator and find out where that size tail, that far back, needs the CG range to be. And move the CG into it.

How far back from the wing LE is the CG?
