about DEVO F12E

The remote devo f12e brush my deviation system, side potentiometer aux5 and aux6 directly from the 100 to-100 negative, even if the remote calibration is also so, someone told me the same question?There is no aux3 and aux4 reaction!

Brush the latest version, I said on the side of the potentiometer problem has been completely resolved! But the U disk mode still can not be used, once the format is set up in the state of the brush on the brush.
