Hi all, Just this weekend installed my new Zenmuse H3 and the upgrade board, updated firmware to 4.0 and calibrated everything. Now my RC won't go in PPM mode, but D-Bus and everything seems to work except for the X1 lever to tilt the GoPro. Cannot calibrate it, slider just won't move. So now my GoPro is facing down, is steady, but only drop-shots... don't think so Anyone similar experience/suggestions or help????
