When physics sucks, try what @Dragoranos said: cheating

There are many solutions for this

1- Place the center of lift behind the center of mass (recommended), that is, put the wings further back, or add larger stabilizers

2- Deadweight in the nose of the plane

3- Remove fuel from the wings and put fuel in the fuselage, it makes easier to work with the wings

4- Redesign the plane

5- cheating

If none of this works, give me a link to the plane
