-42F mavic pro flight

[whareable]

Good ol alaska weather this week

• Shutter/Shake upon takeoff, extreme cold must impact Lift ratio
• Battery started at 36C ended at 22C in 6 minutes of flight.
• Small random delay in response at end of flight
• be very cautious flying -0 or sub zero temps
• no 'icing' discovered, low humidity.

D@mn. The whole video is just cold. Freezing cold. Nicely done. Like the edit.

Random injected observation: at -40º F, it is also -40ºC.

Must be the lowest yet, at those temperatures things could be getting awful brittle though - I notice you weren't going far - so just very brief flight then back in the warm?

Pretty much, upon take off she stuttered in the air, like a vibration, my guess is that the Cold air is changing the lift dynamics of the craft. Never had this at -10F

Considering that -40 is probably also well outside the specs of the electronics components, there might also be issues with parts like the gyros not functioning perfectly, leading to shake. When the fan starts pumping cold air through the body, there will also be extreme temperature differences between the part of the electronics generating heat and the rest of it.

Fan only runs if needed - pretty obvious it won't there

But yes you can be sure you're outside of the specs of every single component in it there, potentially even outside of safe storage range i.e. components may be damaged permanently even just sitting there unpowered (mechanical stresses due to differing thermal expansion characteristics physically cracking stuff).

I'm not so sure. Local temperatures within the CPU or other chips can still get high enough for the fan to be engaged.

Give you credit for standing out there and flying it! About 6 minutes is all my hands would last.

Around 0°C it already never turns on.

Thank you for this post! Heading to Iceland in February and I'm hoping to do a bit of flying there.

I don't know how people can stand to live where it gets that cold! When it gets down to 40F at night here, I can barely stand to go outside long enough to take the trash out. I can't even imagine what -40 would feel like.
