I don't suppose any of you guys own the ESDG Twin Comanche...If you did, it would be easier to compare notes. It is perhaps my favorite airplane, but I just have trouble believing that the real thing requires such constant control adjustment even in a shallow turn. I own a bunch of planes and normally I have no trouble keeping the ball centered at all, without having to pay particular attention to the guage (do it visually, like you said, in the absence of butt acceleration). If the airplane really is that unstable in the turn as the designers released, then I would be happy to abandon all of my tweaks and gladly enjoy the challenge of flying a difficult plane.
Maybe its time to just buy the Seneca instead.
