Hi.

From day one my DJO GO app has registered a max takeoff altitude of 215.0 mtr. I have
never been taking off from more than about 50 mtr above sea level. And with a maximum
of 100 mtr flight altitude above ground level.
How can this be corrected?

No it is very buggy, i have the same problem and it is not possible to reset it beside clearing all flight records but it turns up again at next sync.

I think part of it can occur if the connection fails during flight.
Also i think there has been a change of decimal point/precision in some of the app versions. At some point i had it claim more than 2000m but after a upgrade it changed to over 200m for the same date. It is still more than 200m but truth is more about 20m as max takeoff alt.

I'm finding the same thing here but wonder if "Max Takeoff Altitude" is actually height above sea level.
