Hi Paul. I take it you mean, that If it flies hands off inverted, it will nose down when flying the right way up and vice versa? Sooooo...... it will always need a tiny bit of down elevator, no matter how close I get it. Is this right? I assume then, that there is no such thing as a neutrally handling airplane?

The trim for level upright won't work for level inverted. It shouldn't take much, usually of about the same amount in the opposite direction, for a plane balanced close to the aft c.g. limit.
