The FDS is looking good in 10 knots in that wind range on your video
but so as with the stock FLS in that range.
So I'd like to see doing the same to see the benefit of FDS in 20 knots winds,
because maybe it is only justifying BS.
I'm launching and landing with FLS my S3 DLX 15m in a similar area surrounded by trees,
so I'm not outside of the box
