I have an actual sukhoi 3.1
I set the rates for a similar feel on the sim but no mater where I adjust the cg the nose drops drastically inverted my real 3.1 I just have to breath down elevator inverted.
How can I make the 3.1 on sim neutral( little to no down inverted)?

Old post but for anyone still wondering, Phoenix will eventually respond to cg changes. It just takes more extreme amounts than you would ever consider in real life. You might go back as far as 2-5 inches depending on your taste so don't be afraid to play with the numbers to make it fly like you want.

Sounds to me that the CG is too far forward!!
When you trim for level flight right side up. it requires some up elev to fly straight. When you are inverted that up elev will cause the nose to drop. With a "Neutral" CG plane should fly level either up or inverted.
