In the RC plane world, a balanced prop(s) is an important basic mod all owners do. (Balancing an EDF fan is vital, bye bye plane)..

A balanced prop is a more efficient prop. And, more importantly,  it reduces the load on the motor and the ESC.  It also cuts down on vibration as well as sound.

Unless I'm missing something, (post/thread/video) it seems many P3 owners aren't doing this?

For those who have never attempted to balance your props, you'll be quite surprised the first time you place your props on a balancer. Almost all of my DJI props (both sets) were a bit out of balance. When your props are balanced, your motors will be less stressed and your gimbal won't have to work as hard to steady your camera.

My recommendation would be to buy the SpeedyTM prop balancer. It comes packed with everything you need to balance your Phantom 3 props. Here's a complete list of prop balancer or balancing rods that work well with the Phantom 3:

Here's a good video that explains how to balance props. It's showing Inspire 1 props, but the process works with any props.

If you're good with your set up, great! But ALL new props come way out of balance. Literally, ALL of them.

If you threw a set of balanced props on, you'd be blown away how much more stable and quiet it will be. No the high pitch whiiiiiiiiiiiiiiiiiine.   More precise reactions to inputs, and *likely* a slight increase in flight time.  

Not trying to tell anyone what to do, or come off as a turd here, just passing along some knowledge from my RC plane experience.  I recommend all P3 owners try it out.

I did mine. I found they were quite close right out of the box. Removing the raised lock icon and arrow was all any needed. Used a DuBro balancer with the optional threaded shaft. I tried it without the threaded shaft as shown on a video but that was definitely not a reliable method IMHO.

rayrokni, I don't use sand paper since it permanently alters the props. Instead, I place a small piece of clear Scotch tape on the bottom of the light side of the prop. If it's still not balanced, I add another small piece of tape -- or remove the first piece and add a larger piece.

PS, don't sand anything on the top of the each prop, only the inner bottom, closest to the hub where it's thick. Bad advice by the other guy.

Respectfully, the whole point of balancing a prop IS to permanently alter it. The tape method is a band-aid to the problem.

toddf.perkins, any of the rods at the link below will work. The important part is to make sure the Phantom 3 props thread onto it. And, the props will fit anything listed there.

Everyone of my alleged 'balanced' DJI props were out of balance when I measured them, some quite a bit. I used a dubro balacer and a balancing rod with some tape. Now they are all spot on.

I use the DuBro balancer and small pieces of tape. If you over sand and take too much off you'll have to then sand the other side and if you take too much off that ....

I purchased a balancing rod off ebay rather than use the standard rod which came with the DuBro and found that the props balanced with the DuBro rod needed to be re-balanced with the ebay rod which was designed specifically for the Phantom 3 props.

I prefer sanding, 1500 or 3000 grit.  

IF you use tape, use electrical tape. Stick it to the MID/INNER TOP TRAILING EDGE of the prop.

That was my only complaint - and a small one at that - about the DuBro balancer. To balance the Phantom 3 props, you *must* have their special threaded shaft - and it does not come with the "standard order" balancer package. When I saw I needed the threaded shaft, I called the company. They were very polite, but I had to spend extra to buy the threaded shaft. I personally think that if they're advertising it works with the Phantom 3, even if they have to raise the price, they should include the shaft.

For those new to the world of balancing props, many, many RC plane props are NOT threaded and the mounting hole goes all the way through the prop. The threaded, self-tightening props are not yet the same kind of standard we're starting to see in quads.

Another commonly used technique is to quickly wipe a dab of super glue along one side of the props.

My preference is for the tape. Despite the rpm of the props, the tape tends to stay on there very well.

The two obvious schools of thought: (1) remove weight from the heavy side by sanding it gently or (2) add some weight - very slowly and very lightly to the light side.

The tape method has been used by RC plane guys for years. Works fine.
As I wrote in another part of this thread, there are two schools of thought:
(1) add weight to the lighter side
(2) remove weight from the heavier side.

The beauty of the tape technique is that if you put too much on, you can remove some. If you sand too much away OR SAND AWAY IN THE WRONG SPOT! - it's much harder to correct.
