Usage of Storm32 Gimbal with Pixhawk via mavlink


i am using a Storm32 gimbal with my copter 3.3.2 on a pixhawk as described in

My questions are:

  1. can i remote trigger my Sony Nex5N via mavlink and the PWM out of the Storm32 gimbal?
    At the moment i just use Aux2 of the Pixhawk and RC Channel 10 with this fella.

  2. Can i move the camera relative to a stick movement like the relative RC modes on

  3. Is it generally possible tu use autotrigger for the camera and maintaining the possibility to remote triger a video with the same channel (low = photo, mid =off, high=video)?

Thanks in advance!
