I'm not a newbie but I'm just getting back into flying after almost 6 years! I've got a sig somethin extra arf that has been flown many times, and was well balanced. I recently put a new .46 thunder tiger on it ( I LOVE IT).
However in level flight it tips heavy to the LEFT, so I have my trim set 80-90% to the right to compensate.
After getting home, I tested the lateral balance by hanging from some string, and it actually is quite heavy on the RIGHT side.
Maybe the muffler is heavy?
But how is it that it's right side heavy, yet I need so much right trim?
