I will repeat what Colin has told me. This is going to get fixed. I will confess that in beta testing I was the man with the actual time logged in the Baron 55. So, it was my primary duty to ensure the FDE was accurate in accordance to the real airplane and to ensure the flight modeling matched as close as possible the performance on the actual aircraft.
I did not in my testing use the rudder with over 50% inputs and measure the totality of roll experienced because I would never fly a real world piston twin where I would be at cruise speeds in level flight and then essentialy stomp on the rudder to see what happens! I would strongly suspect what I saw would not be pleasant. So, I tend to test in a way that matches actual flying of the actual airplane. For what it is worth, I was never during testing able to perform a barrel roll with just using the rudder. Clearly if I had discovered that I would have flagged it as an item. Several people have reported they can do this. What can I say? I was not, but I certainly did not test for such a thing because I never would have done such a thing in the real airplane.
Again, Colin has told me this will be fixed. I ask your patience.
Thanks,
Ken
