Bob,

You might be slightly tail heavy. Try shifting your CG forward and see what you get. If you are tail heavy your mixes will be a little more. When it is right you can fly it with 0 mix, but if you get really discrimination there will be a SLIGHT pull to the gear. I know people will talk about 0 mix planes, but I've yet to see one if you really push the envelope. With the speed changes and the fact that we fly props you will never get rid of all the effects from prop.
