Just got APM2, and setup a test bed to bench test before I stick it in the plane and go.. I noticed something I think is odd. In stabilize mode, when I use rudder, I also get some aileron... Problem is I get aileron that is opposite what it should be...
For example with no rudder, when I give stick to bank left it banks left, and when I give stick to bank right, it banks right... When I give left rudder, I get aileron that would make the plane roll right, and when I give rudder to go right, I get left aileron roll. Is this normal??

Thanks for the input guys, but I figured it out... There is a setting in StandardParams that I changed.
Rudder Mix (KFF_RDDRMIX) was set to .5 and I changed it to 0. This eliminated the issue that I was seeing. Hopefully this helps someone else along the way.
Now I have to wait for my 3DR Radios to get here then I can put it in the plane and fly next week...
Also, so others may be able to help, what transmitter (radio) are you using?
Also test the surfaces when you tilt the plane around in stabilize mode. My elevator moved correctly when I moved the stick, but when I tilted the nose of the plane down the elevator would go down as well. Luckily I noticed this on the bench and reversed the elevator in the RC config panel. :)
