I will also add that I'm not that good of a pilot so I'm not sure I would notice if one was not centering well. I certainly can notice how quick they are though. On all my other 3D planes I run zero expo on my rudder and all other surfaces are around 20-25%. On this thing I have had to add it to the rudder and all surfaces when in high rates are up to 50% expo. Overall the plane is great so far but I do need to find a different motor to get the power I would like to see.
