If you work the CG back a little at a time you can check flor in flight stability with the gyro off. Fly upright, trim for level pitch. Fly the next pass inverted. Hands off inverted should have the nose dropping slowly for a pitch neutral airplane.

Once the CG is set in the neutral zone the pitch will be much more sensitive requiring caution to. It over control the aircraft at first. It will fly faster using less fuel and land slower with less elevator deflection.
