QuadPlane + frame works like an X frame

Hello,

I am working on a PLUS frame QuadPlane. I set these parameters:
Q_FRAME_CLASS = 1
Q_FRAME_TYPE = 0

I am checking the outputs for the 4 ESCs, and recognized that, all 4 change, when I use elevator, or aileron separately. I believed that only front and rear motor outputs should change, when I use elevator. And only right and left motors output should change, when I use aileron. So it works like an X or H frame.

Is it a correct working? Or did I make any mistake?

Thanks, Laszlo
