Weather conditioner for copter at extreme cold weather

Hi everyone,

Does anyone have experience in flying copter at very low temperature on high mountains, up to -40deg Celcius. I need help to find some heater/ weather conditioner for the electronics and the battery to fly in this weather. If you know some equipments like heater or weather conditioner for drone please let me know, I really appreciate!

Thank you.

I’m just curious at what altitude are you trying to fly your drone? And what’s your setup? You know at higher altitude air has lower density which makes difficult for your copter to fly. And also lipo battery would perform poorly at that temperature.
