I am thinking about trying third party SW like Litchi. Especially because of the possibility of pre-programming the route and using a VR display. Has anyone experience with DJI's service if an accident occurs using 3rd party SW and does DJI then cover damages if they are caused by the firmware? What SW is recommended for VR display's and what displays work best? I have reading glasses (+1.5). Does Litchi work with the Samsung Gear VR(2)?
