Anyone able to explain why, in flight, the live feed will show I am wide open at 52 MPH (with wind ATTI mode), but when I replay later from the user screen, it never goes above 17.2 MPH in the playback?

Am I going 52 or 17?

I noticed the same thing, it would be nice to see max speed on the flight info page.  I flew today and had speeds well over 30 mph, but the max speed on the playback was 15 mph.

Are you taking into account for the wind that the Inspire is flying in?  Because a tailwind will show a much faster airspeed as it is flying in a wind that is going 15 mph already. (Example: 15 mph wind, 20 mph Inspire = 35 mph ground speed with the wind). And flying into that same wind does the opposite. (15 mph wind, 20 mph inspire into that wind + 5 mph ground speed) and all the GPS sees is how fast the Inspire is traveling across the ground. Not the air or the speed of that wind.

I think in playback mode it is showing meters per second, but labeling it as MPH. I think it is a bug in the iOS App (0.9.2 has it)

Yes it's a bug in the iOS app, will optimized in next version.

I've not been able to go faster than 17.2 MPH. Is that the way to go faster, to put it in ATTI mode?

It can' the that.  I do fly in ATTI mode and though the craft hauls ass, the replay shows 17.2.

The speed is subject to the value on live video feed.
