I started the SB and after disconnecting the cables, and servo arm I checked the balance. It takes 9-10 ounces pulling down at the very edge of the trailing edge to be level. My plane is a 2015 model and the KIA does not mention balance. Should it be level or is there an offset required to fly correctly? The plane flies great and has no bad habits, although I may not be the best judge. Maybe it could be better?
