Hi all,

In Sweden where I am it was around 0 degree celsius and sunny today so I went out flying. After 20 minutes my quad just stopped all the motors and fell from the sky. Thankfully at a grassy field from about 3-4 meters. At the time I was about 15 to 20 meters from the quad so it was not loss of signal.

I rebooted and got the blue light but the red and green lights were blinking and I couldn't get it to work at all. 

When I got home the thermometer showed -1 and I couldn't connect to the FC with the usb cable. My other quads connected so not a PC problem. After some googling I wrote it off as flight controller failure and was resigned to buy a new FC.

Some time later this evening I was going to show my friend the quad and connected the battery to light it up just for show and I got a normal response with a blue light from the FC. With the TX active it flew normal.

So, from this I get that Naze32 do not like cold weather. Do any of you have any experience with cold weather and flight electronics?

I try to fly when I can and I have flown it for more than an hour in +5 to +10 degrees without problems and when I flew helis some years ago I can't remember any problems with cold weather.

BR,
Henrik

I can add that it is a naze32 acro rev 5.

i have never heard about flight controller stop working at 0 degree... i think they should work at even lower temperatures...
so are the FC LEDs still on?

they say your FC could freeze... but shouldn't literally freeze hehe... I am more concerned about condensation and your LiPo

Yes, condensation is an issue. Especially after I've put it down in a heap of wet snow

The blue led was lit and the green and red was flashing alternately. When I got in and tried to connect with a usb cable it didn't show as a serial port. And later that night it worked normally again.

I think I'll put it in the freezer for a while and see what happens

yea i think the heat from electronics just melts the snow and water got into the circuits.. be careful though your FC could go crazy, that happened to me once (crashed into wet grass previously)
