We have put the VOXL Flight deck on a custom H8 drone frame. It has been working well but we have been having an issue taking off in position mode. We also have a m500 with the VOXL flight deck so I know taking off in position mode is possible. I have been hand launching the H8 and have been very successful with this approach. We cannot do this all the time and am wondering Is there a minimum height the tracking camera needs to be off the ground for successful takeoff from an optical constraint? If not is there a parameter for setting this value? Been looking but have not found it.
