Ok, I have a potentially strange question to ponder.

I'm building my first airplane from a custom kit (87" 50cc Yak 54)

I want to keep most of my weight centralized and balanced.

It seems to me because of muffler position and thrust angle more of the engines weight winds up on the left side of the plane. I saw a picture of someones plane and they had the engine rotated approx. 10 degrees clockwise (viewed from the front)

I'm wondering if anyone has tried this and knows what angle gets the weight centered? I know it will change depending on how much right thrust, length of standoffs etc... I just think I could prevent having to add more weight to a wing tip than necessary for lateral balance.
