I'm flying a Great Planes Reactor. I'm trimmed for level flight at about half throttle cruise. The elevators are pretty flat. I just flew a scratch built giant scale profile that was fairly tail heavy (42% MAC), and that was too much....so I'm guessing somewhere around 37-38% might be just about right. I like to fly my indoor stuff so it requires just a very lite touch of down elevator when inverted.....I was just wondering if anyone use a MAC percentage that seemed pretty standard for 3d?
