That is almost exactly the technique I use. I use a loose piece of sandpaper though, as this allows you to sand the blade evenly and not significantly alter the airfoil of one blade more than the other. That way the blade is balanced by weight and aerodynamics so that each blade maintains as close to the same lift during rotation as possible. I start by removing all the flash all the way around the propeller before even putting on the balancer. I also try to finish with a finer sandpaper, sometimes, not really necessary though.

James. Very good. In regards to small black props, I clean the blades and then i use very small pieces of foil tape on the back of the lightest blade till it balances. This method doesn’t take much. Then i touch up the tape with a black sharpie. Many different ways to skin the cat so to speak. I prefer not to remove any material when i’m able. P.S. I like the magnetic balancer you have. 👍👍😊
During my RC boat racing days I balanced my props to gain a speed advantage. Same applies to plane props as well. Balance = performance and speed Great video James!
Good tip James, I tend to sand off the front of the prop to avoid altering the concave side of the blade on the principle that the concave side is the shape that is grabbing the air and creating the thrust, unless of course some aerodynamic genius tells me otherwise !
@@Navy6438 probably 80 or 120 grit, don't remember. But again, smoothness doesn't matter on the back of the prop, your just removing a small amount of material to balance it
3D printed propeller blades are tricky to make, because each blade has a high chance to asymmetrical making them mostly ineffective, and yet I try my best to make it happen
This is actually very quick and easy to do. Shouldn't take just a few minutes. It is important to turn off all fans, a/c, or anything that causes air moment in the area though.
It used to take me nearly 30 mins to sort out my 3 bladed props , but now that time will definitely be shorter. Cheers James for this great tip. 👍👍👊🇬🇧
No problem!
As you get closer to balance I suggest going to a finer grit sandpaper to get back to a polished surface.
would that matter on the back side of the prop?
What grits?
That’s a good one for me James. I was not sure how to do a 3 blade, now I do 🤓.
That’s quick and clear. Good job James 😉
Thanks!

Awesome. Just what I needed to know.
Nice wrk. Very clear message
Thanks so much!
Great job and simple explanation James, thanks for the tips👊🏼👊🏼

@@MotionRC thank you so much James!!! Humbled buddy👊🏼
Great video. I’m looking for a bigger balancer that I could use for my gas engine propellers. Any recommendation?
Great tip James
Thanks Jeff!
Nice tip James I really like that magnetic balancer
Me too!
@@MotionRC I need one of those.

That works well, as well for sure. Good tip
👍👍😊 Just ordered one (for each video - so 2 😉) - now I have perfect gift for young modeler friends ..
soo satisfying
Good information. Thanks
Glad it was helpful!
Great stuff thanks so much for sharing, regards from Alan in the UK 🤗🤗👍👍👍👍
Good method for balance 3-prop

Great video James!
Good tip!
Would like to see balancing a 4 bladed prop like the one on my F4U Corsair. Thanks.
Great video.
Thanks for the visit, glad you liked it
Excellent tutorial 👌 much appreciated 👍

What grid sandpaper are you using
Whatever I have on hand ..won't make a difference on the back of the prop
Are u in the thousands or hundreds, 1000 grid or 500

@@MotionRC no but a heaver sandpaper will remove more vers a lighter will remove less, i think 320 would be great
Which side of the prop blade do sand on? Front or back??
Always the back
Good vid!
Thanks Randy!
What grit sandpaper like 1000?
What grit sand paper did you use?
That was 220, but shouldn't matter
how come no one shows this with something as small as even a 5 inch? Does this not work with those?
Im try this balancer. I tried 2 orhers that the balancers themselves were out of balance.
What about the hub balancing?
Great tip 👍
very useful
Is the mig 15 better edf trainer than the f-8 crusader?
I wouldn't say that as don't consider either as a trainers. The Rebel, Hawk or Avanti would be better trainers.
@@MotionRC thanks ! 🤗😆
3D printed propeller blades are tricky to make, because each blade has a high chance to asymmetrical making them mostly ineffective, and yet I try my best to make it happen
I just add a small amount of thin CA to each blade that needs it.
Another good way to do it
3 blade props take time and patience.
This is actually very quick and easy to do. Shouldn't take just a few minutes. It is important to turn off all fans, a/c, or anything that causes air moment in the area though.
Yeah, what I wanted to make sure I didn't do was take too much off the heaviest side then have to start the process over
👌
You don't ever sand on the blades.
