Guido's Mandarin maiden flight, recorded in flight by FPV.
In this flight I'm using a DIY vario for the first time (thanks Kapteinkuk for development and software).

You can compare the vario sound with the height changes measured by the autopilot, shown at the middle right in cm/sec, above height.

Autopilot is UavDevBoard3.

I'm using for the first time a DIY drift free head tracker also (thanks Dennis Frie for development and software).

I forgot it in flight: no more drift reset!
I my previous flight I used the reset button tens of times.
