A forward CG will give you that "squirleyness". Correcting the CG/CP relationship will correct it.

You mean "a forward CP", so the distance between CG and CP will be
shorter!?

Sorry, you are right. That would be an an AFT CG problem.

CG is ahead of CP by some distance, and a download on the tail
holds the nose up.


A large tail area and long tail arm won't fix instability.

That's contrary to what I learned, so please explain further.

Stability is a CG/CP issue.
