Cold-weather flying video over a river which is almost frozen over.  It was about -10 C (14 Fahrenheit).    This was my first time flying in freezing temperatures, I didn't have any issues.  I made sure the batteries were warm (let's say room temperature) before takeoff, and I let it hover 1 metre up for a minute before flying further.

That looks pretty cool.

Cool geometric design in there.

It's amazing ! That icy river is beautiful !
