My GP Venus seems about as straight as an ARF can be.
I have the CG balanced per the plans.The model has the inverted engine muffler on the left, making it laterally tip to the left every time. So, I put a little weight on the right wing tip...not enough to make it perfectly lateral, but close.

When flying, the model requires a little LEFT trim on the Ailerons, even though the RIGHT wing is still a little light.
Is this due to torque?

Should I put even less weight on the right side, making the plane less laterally balanced on the ground?

As it is now, it tracks well and flies through loops well, it just has a slight bit of left trim on the ailerons
