First flight today after updating firmware to 02.00.0600 and about 5 minutes in I noticed a horrible wobble while it was hovering stationary. It was quite foggy and about -5C temp and I was getting some footage of the cold fog. I took a short video of it for posting here then landed, however upon landing I noticed significant ice buildup on the props, which turned out to be the cause of the wobble. Wiped the props clean then flew again after fog had cleared and all is okay, so far.   

So if you're going to be flying in fog in cold temps, beware of this.

Here is what the wobble looked like from the ice buildup on the props.

your very lucky it was small amount of uildup.haha

It seems that the weather is not appropriate for the flight test. Change to another sunny day and check whether the wobble remains, we will appreciate your feedback.

Thanks for the advice !!

Maybe spray with a little deicer.

Yes I flew it again when conditions were better and it does seem ok so far.

I realize that it was the ice causing the wobble - The intent of my post was to warn others that flying in sub zero fog will ice up the propellers.

Thanks for sharing your experience. Nice to know the drone works now. Enjoy it!
