Hi guys,
As for the wind, the manufacturer call for maximum wind velocity of 17.8mph - 15knots.
This take to account the accuracy and safety of the unit when not in "manual" flight modes, like we used to to film(hope to have longer version to you all by tomorrow).
Our insurance cover us to high wind speed, per our safety discretion on the location.
The bird used in the video was a S900, with a GH4 camera.
Well, we can get pretty close, but we do have a lot of experience doing that, and I would say its a matter of safety more then anything really,
Cheers
Ido
