So many new and even experienced drone operators fail to take this simple setup step before flying their drone, it may be doing more harm than you think!

It can't be good for your motors to start them with the props folded, everything is so out of balance.

Great share!  I don't think I have ever left the props folded on my Mini, but have not been taking the extra step of pulling to get everything completely straight.  I will be now...
As you said, it is so simple to make sure the blades are completely straight before starting them.

I have seen a similar video on Facebook and must admit I never used to open props but since watching that I have always opened them up for every flight

I only failed to unfold them once, on the first try, since I was used to the mini and that seems to be ok with it. Not going to ever happen again after I saw the wild vibrations that caused.

I never unfold the props before flying. Always thought they separated right after starting the motors. From now on, I will also unfold them before every flight.  Thanks for sharing!

I have to admit,  I don't ALWAYS spread the props.....usually,  but NOT always.  That will change as of today!!

Thank you

Thanks folks! The DJI manuals all the way back to the original DJI Mavic Pro state that props must be unfolded prior to flight, and yet as many as 30% of consumers aren't doing it before flight (according to our poll on the YouTube channel). This is shocking, let's share this video to educate drone operators!

As you said, it is so simple to make sure the blades are completely straight before starting them.

It doesn't matter on the Mini that much because the props are free spinning on the screws that ties them to the motor. Even more, they spin so easily that as the motor starts to spin they will first remain behind and only then fully extend due to the centrifugal force. So there's no point in arranging them manually. On the Air 2 this is completely different as the props are pretty stiff in place and the central hub is securely held by the motor. Furthermore, the two individual props stick together which makes it worse if the motor is started like this.

This is true that the props spin pretty easily on the screws on the Mini, but if nothing else, it is a good habit to get into.  One of these days I may well buy a different drone (such as a Mavic Air 2) where it is does matter.

Thanks for sharing, I often don't open the propellers on my Mavic Air 2.  I'll keep this in mind.

This makes a lot of sense. What's missing is any empirical data showing a difference between folding versus not unfolding. Don't get me wrong - I'm convinced and will be unfolding my props going forward. What I don't see is the solid evidence that this makes a difference. This evidence would probably be impossible to come by though, so I know that's not really possible.

I agree with you empirical  data would be useful. While this shows the impact visually of folded props I am not sure of the damage this would cause. At best guess it puts some stress on the motor bearings and rear arms

I suspect that it would be no different than the flying of the drone in sports mode and the impact of the auto braking. I would like to see the stresses of just basic flying in slow mo video.

To date i have never had an issue but I will try and unfold in the future.

Edit never mind ....not redoing my post sometimes this site is retarded for Android mobile and what's up with just a thousand word cap ??? LOL yes I am trying to write a novel! Lol anyways I agree with always putting the plates out straight I have always even done this with my RC helicopters blades shouldn't be tight in the prop hubs nor in a helicopter so it's kind of common Sense think of a helicopter doing this with the blades folded almost 90°, wouldn't be pretty and also on a drone this does do damage over time you want notice probably till after 30 or even 100 flights but I bet you some motor screws would be loose even though they're loctited and I guarantee you might even have a jangly motor can .... This is why putting blades out straight will reduce wear and tear.  if I'm home I usually just keep props straight this way I can just grab it off the shelf and go and it's still in the same neutral point so  the next start is very smooth

After seeing this post I have been unfolding my props before launch and that makes sense. That said, I have to say, there's this odd sort of little excitement I have watching a video and seeing the drone wobble a bit before it takes off. Can't say why - maybe it's just me. Like in this short video I made before I knew better.
