I just put the finishing touches on my Tower Trainer ARF. Balancing on the C.G. was perfect, I didn't have to move a thing. However, when I tried to balance laterally I found that the plane is pretty significantly heavier on the right side. I'm pretty sure it's the muffler hanging out there that's causing this. My question is, how important is lateral balance? Can I just correct with trim and be ok? If it is important, how can I correct it? Thanks.
