Default Do servos function in cold wheather?

hopefully this is the right spot to put this in

anyway i just got a dw yak jr and i was excited to flight it so i flew it outside in my caldasac(i live in wisconsin) and i had 2 servos break and after about 1min of flying it would take my elevator servo an extremely long time to move.

there were no major crashes and no reason for any servos to break

i let my plane sit inside for about 15min turned it back on and my elevator servo worked like normal...

help me...i think cold has some thing to do with it

p.s. it is about 15 degrees

thanks for any help you can offer

I would think your servos would be fine in that balmy weather.

BTW what servos are they? If you say they are Mojos', that is your problem right there.

We had bought 24 Mojos and all of them failed. DW (Steve is it?) took them off his site now.

I don't think it was the cold -based off of info from that other thread.

If there is any grease on the servo gears they will be affected by the cold.

Hi Kyle,

I'm thinking it may be the servos that you are using. I quite frequently fly in the winter (both helicopters and foamies). I use HXT 5g and 9g servos in my foamies from hobby city (because they work well and are cheap) and I've never had a problem.

Here is a video of me flying one of my foamies in about -6C weather (22F). I fly in down to about -15C (5F).. anything beyond that and my hands/fingers get too cold.

Don't let the weather get you down; find a setup that works for you.

Batteries do have an issue in the cold - but never seen any issues with a servo.

I've never had a problem with servos flying in cold weather. Its usually my old arthritic fingers that stiffen up.
