I don't know if this is a problem in all these ARFs. My Seagull extra 300s had a big issue. The main wing was not balanced. I used the same servo and connecting rod setup on both sides of the main wing. The left side of the wing was heavier, could not figure out why? Checked everywhere nothing to be found in the main wing that would add weight to the left side. So sadly I was forced to add 15 grams of weight to the right side of the main wing just to balance it. I think this is why this plane likes to snap around itself when you try to use full elevator. Let me know if you guys have the same issue, do your main wings balance correct????

Thanks
