What was the top speed you achieved with the Phantom 4 in sport mode with a tailwind.

I've pulled off 53.9 mph with tail wind

53.9

I pulled off a 54.25 MPH flight.

Seems very fast...

Actually that speed is easy to achieve with enough tailwind assuming the onboard GPS measures ground speed which is affected by wind speed.  with enough headwind the bird could be at max throttle and not be moving over the ground.

Here is my speed run, no wind.

I'm so absolutely confused with all the aspects of yours post.  You are correct the wind has no effect on ground speed but it does have an effect on objects in the air.   

If you have an object flying at 40 mph in the sky under its own power, and you add a 10 mph tail wind that means the wind speed is added to the craft.  

Very basic break down.  Take an rc car.  If it can drive 5 mph and you drive it down a conveyor belt moving at 5 mph the car will essentially be moving 10 mph.   It's own speed and external effects as well add on to over all speed.

Hope this helps

everything you said is correct and so was my post.  The difference between True Air Speed (TAS) and Ground Speed (GS) is wind.  If your craft is flying a TAS of 10 (pick any speed measurement; mph, kts, kph, fps...doesn't matter) and the wind speed in the direction of travel (off the nose)  is 10 then the GS will be zero.  Turn the craft 180 degrees so the wind is coming from behind the craft and the TAS of 10 affected by the wind speed off the tail of 10 will give a GS of 20.

soo what you guys are saying is, P4 flies faster WITH the wind? i think we can close this case.

P2 flies 60+mph with crazy wind:

For a split second I saw a top speed of 63 mph on my phantom 4 last night with a pretty good tail wind. It was cruising at 60 mph.

You are all crazy. I flew last night and winds were gusting over 20 mph, but I was happy to go up and down and stay in one place. I am getting braver every day though.

I was flying right before a storm the other day and got right at 70 mph

Not speed, but related......

We had a very windy day here in KY. Winds were running about 20-25mph with gusts over 40mph. I thought I would try the P4. Amazing how well it worked in those conditions. Held stable very well. My pics and video were pretty darn level. Actually kind of amazing.

Wow 60mph that's just nuts

Got Up to 60.5 in atti mode at 232 feet off the deck.  Will post pic ok when I get hone

Ok so not sure if my P4 was recording speed properly but I got 69mph yesterday with a tail wind lol?!

Over the weekend I hit 67 with some wind

Hit 80mph yesterday with a 20-25mph tailwiind.  Couldn't believe how fast it was flying.
Hmm, which do I trust, HealthyDrones or the DJI Go app?  Go app said 80mph, HealthyDrones said 61mph.

We had a nor'easter blow through a few days ago and my phantom 4 clocked out at 123 MPH with a 60 MPH tail wind!!!!

screen shot of getting up over 60

82mph.... with a tail wind.... In the Microraptor case..... In the back of the Jeep

My p3 pro always goes 50 mph with tailwind but its prolly not a strong one yet...
