some things to get an understanding of
in the location screen where you put the measurements in for where everything is can be tricky. make sure + and - values are right. red vs. green...... the closer you get all that and the better you understand calibrating it the better off you are in the wkm setup part. other than that gains make a difference if she wants to nose over in manual versus hop straight up,,, along with cg of course
those bone stock 550 seem to like a pretty high gain, like 140-160 manual........ more weight you put on it the less that is an issue. read the manual about the gains and go give it a shot.
if you put the gain on a knob, lower the end points of that channel so it moves the gain just a little, don't let it go from 50 - 300,,,, make endpoints like +10 - 10, move the knob to zero and enter the gain number assigned to the knob to the middle, lets call it 150,,, hit write till the text isn't red and move the knob to see how far it sweeps. the worse thing i've seen is too low of gain. too high it just shakes, too low it falls off plane and shoots off, hard to control
