15 to 25mph wind makes a BIG difference in Ground Speed
I missed the Kite Surfers so I decided to just play going up and down the beach a few times
Up Wind my P3S barely made it to 30mph but Down Wind was a different story...lol
Sorry I didn't learn picture in picture in my latest Edit Software yet because 10Ft off the Water/Waves at 50mph looks pretty cool

Yup I was flying at 10350 ft altitude near in the mountains.  No wind warnings but on my return leg of the journey hit over 50mph. I only saw that on my flight logs after the flight.  By the way the DJI App shows you going 20mph faster than you are. Mine shows over 70mph. Use Phantomhelp or healthydrones and see what your max speed is on their data.
I started a thread about the speed discrepancy a few days ago.
