Justin,

Everyone's parameters will be a little different depending on how you've set up your plane.  Servo throws will be different from plane to plane.  What you need to do is go through the procedures described in the manual using the FBWA first.  check to see that you are getting your pitch angles with full up and down elevator deflections.  If not increase P.

Here are my settings which have worked pretty well for me:

I understand that, and thanks for the screenshot.

But the difference between a P of 0.6 and 3.0 is huge ... so huge that there seems to be no point offering config files to look at?

i flew today at 0.5, the default is 0.6, you have 2.0 and the example config for skywalker is 3.0. these pretty much span the spectrum possible.

I'm wondering what a value more than 3.0 says about the airframe or the amount of movement in the aileron or elevator at full deflection.

I've read in several posts from Chris Anderson that the default PID settings are "woefully conservative" so that planes would operate safely before over-correcting themselves into the ground.  In those posts, he has advised to expect large value adjustment before you'll see expected results.
