V922 (FBL100) Is this normal?

Hi, I downloaded a FBL100 model file for my V922 and I've adjust it to suit my needs, i mean basic fly , no 3D, so I've a pitch curve with NO negative pitch and a max of 75% angle. The throttle curve goes from 0 to 100… I can hover without problems in a small area (at least for me) but when i land the heli I noticed that the trims has changed so switching off and on my Devo 7e I got a warning telling me that the throttle is over 0… Is this normal?

I've attached my model file….

Thanks in advance.
