Ok...Be a bit careful in your assessment...To fly straight and level you must be honest with yourself...

My personal experience with this was very interesting. I belong to a very small club and was considered one of the better pilots (ok...for those that know me, it's a very small club...LOL )

I thought I was good until I went to my first contest...I practiced all the wrong things for three years and I could never get my plane to trim well, pulled to the left...sound familiar... I couldn't put enough right thrust to compensate for the huge pull to the left... I knew my plane was built straight as I'm a perfectionist to a fault (an ARF will take me months trying to make it look good and be straight).

I agreed to meet Mark Atwood at the contest and he would help trim my plane. He flew it through some pretty amazing maneuvers landed it and said, yep...It just needed a click of right trim...He followed on with, "Your problem isn't the plane"...Time to be humble and honest with my self...[]

My problem was -my straight and level wasn't straight and level-...It looked level from the ground, but the wing closest to the runway was actually low...Mark worked with me as well as others until I could recognize straight and level...Now pulling to a vertical is much easier and when I miss, I know why...Again being honest with my self, the wings weren't level...

Now the morale of the story...Your airframe being crooked could cause this and I'm not smart enough to explain them all...However, be honest with your self assessment in flying straight and level...You may only need to adjust your perception of the plane being wings level viewed from the ground...
