Batteries hold less charge and discharge quicker when cold so much shorter flight time. Keep batteries warm inside coat pocket until ready to fly. Not harmful in the long run since cold exposure so brief
I did a flight today in -10 °C / 14 °F. I had no problems whatsoever, except I got very cold on my hands This is my first post and would like to use this opportunity to thanks for a good community / forum.
Thanks for the additional info. I'm impressed that tello can withstand -23. I'll try it next time.Winter flying works fine with tello. Batteries will not last so long tough. Couple of days ago it was around -23°C in here (finland). Tello did fly nicely. Batteries lasted about 8-9mins in that weather.
