Never did this myself until just recently, and I will say that all four props from DJI (stock ones) where all off a bit.
Then after doing the balancing it seemed to just purr at idle, sounded much smoother and quieter.

I've been looking at prop balancing kits, which do you use and how difficult is it to do?

Here's the one I have: https://smile.amazon.com/gp/prod ... 1_s00?ie=UTF8&psc=1

It's simple as pie. You can either sand the heavier side or add tape to the lighter side.

Thanks wmcvey! That 1st one is what I'd been looking at - and now, have just purchased

I have a load of damaged props I don't use, maybe good for an art project, a few sets that are pristine and 2 sets still in the packaging from DJI, it'll be interesting to see the difference.

I have the Du-Bro (2nd link wmcey listed) and it is easy to set up and use.  Of the eight props, 2 were perfect, 5 needed little strips of electrical tape and one need grinding off some of the hub to perfectly balance.  It took perhaps 30 minutes and will not be done again (what cold change).

Just make sure your table is level as can be, even if you have to shim with a business card.

Just a suggestion, rather than add weight to a blade you can sand the tip of the heavy blade with fine sandpaper. You will have to remove very little to balance.
I would avoid, my opinion, grinding or removing material from the hub area. A fracture in that area can cause the blade to separate possibly causing severe damage to you and/or your drone.

Add tape? Sounds clunky.

I saw a guy on Youtube, adding a dab of clear nail varnish to add weight, letting it dry then another coat until perfect balance was achieved. That strikes me as far more reliable and elegant than sticky tape on the props?

Didn't think my props needed attention either, then I just decided one day to buy an inexpensive balancing tool and check the set I was using. They were all off to a small point and after adjusting them and reinstalling, on the very first test flight I immediately noticed the props sounded smoother and quieter. If my old ears can immediately notice a sound difference at idle that has to mean something.

As this was my very first try at balancing props I took the most easy path, using "scotch tape". It's clear and very thin, almost invisible on those white props. You're adding a piece (at least for me) that's so small, maybe 1/4 to 3/4 inch (1 to 2 cm). In my mind that's so small I don't see a negative with using it.

Not clunky at all.. increments are very small and becomes basically transparent when on.  Definite upside vs. accidentally taking too much off with sanding. :-)  Usually it doesn't take very much to get it balanced.  I try to keep the tape closer to the hub..  I have the Dubro 6mm which comes with a rod for both screw directions (clockwise and counter clockwise).  Works great.

One like this https://www.hobbyzone.com/building-supplies/hand-tools/balancers/topq5700.html?gclid=CNqtqY77uc8CFQlahgodpGkGTg you just have to drill a hole through the top for the shaft.

If you really want to be serious, weigh each prop.

With the Du-Bro, the table doesn't have to be perfectly level.... Just enough so that the whole thing doesn't topple over. I'm very impressed with this product. It's very sensitive to the tiniest prop imbalance.

A local Forum friend @Rigworker, kindly let me borrow his Dubro prop balancing set. It showed me that the DJI props are pretty accurately balanced right from factory.
I don't get vibrations or jello in my videos, so it has never been a major concern of mine.  But it was fun to check them over. Nothing wrong with being sure that your rotor blades are balanced.
This is a camera platform, after all. So ultimate stability and smooth steady flight is desired & required.

Waiting for the Sun to shine, so we can go flying together again. Hopefully before the North country is blanketed in white fluffy, cotton ball looking, winter garb. Hahaha

Thanks for the reply. I thinking about returning my first one (just got it) and getting this one instead. The one I have now if the tabletop is not almost dead level the rod rolls to one side. I'm thinking this one won't be so sensitive to that issue.

Everyone is talking about balancing. Former heli flyers know tracking is the question you should asking about. Just because the blade is balanced in a vertical balancer does not mean it horizontally tracks true. You balancers have hopped on the wrong band wagon. Does it track true?

not dismissing your point on tracking in any way!
BUT
I  would disagree that proper prop balance is "the wrong bandwagon"

as long time Phantom flyer I can assure a poorly balanced prop can cause many flight issues.
factory DJI props do seem pretty solid balance for the most part.

the off brand XOXO, and others found all over the internet are not so well balanced.
buy a set and fly without balancing for fun and see the difference your self as test.


good luck and have fun flying

If it takes more than a sliver of tape on the underside of your prop or hub, your prop is really off balance. Save that one for last resort. I would say the best prop is usually the one that required the least fiddling with.

Oh great - now I need a dial indicator too? I agree that might be a good test as well. A bad result would mean tossing the prop out.
But a balance problem is easily corrected and will stop the vibration that ruins video and stresses motor bearings.

This is the one I use - good price.  I use matt finish clear nail varnish to balance.  I've seen the videos of some using tape, sometimes what looks like gaffer tape. i think that would take away the aerodynamics of the prop.

That-s how I do mine except if the hub needs balanced, you might end up with a pea sized glob of varnish on the hub before it's balanced. On my hubs I use epoxy or CA.

It's a personal preference between the O.C.D. and the general enthusiast.  
If a prop is causing that much vibration, sure balance it, or use another.
