I was a bit concerned when I recently read that you shouldn't use the DJI Spark below zero Celcius as I'd bought the drone for sking and climbing in the mountains!
I was naturally expecting poor battery performance and reduced flying time as with most electronics, once the temperature got below zero, but have not noticed that much difference.

I've been pleasantly surprised with it's performance at just below zero down to minus 7 and by using hand launches and catches have so far kept the drone out of the snow.

I keep the drone in my backpack when out climbing or skiing and after several hours of x-country skiing at well below zero, Sparky still flew well and got some amazing shots through the snow laden forest trails :-)

If flying near the roadside, I just switch everthing on and connect up the app inside the warm car before, flying outside.

Good to hear, nevertheless I would recommend to read this very good tutorial: https://forum.dji.com/thread-120497-1-1.html

Sparky has surpassed my expectations and has been really useful for getting winter climbing crag photos for climbing topos and exploring new unclimbed ice and ski lines.
