I made a sensitive Prop Balancer from an Old Motor + my Prop Balancing Tips.

[@oliverdots]

Great vid Dave. Just one thing I would add. When I balance my heli blades I put tape on the lighter blade but don't fold it over until I check the balance. That way I can simply cut off part of the tape and balance again. When the balance is right, then I fold it over. Just my 2 cents worth lol. Keep the great vids coming!!

[@johnclarke7938]

I absolutely AGREE with the "Enjoyment of making somthing to do the Job" and I think your idea Rocks

[@tomterahedrob]

Your experiments with the one bladed props and copters are an inspiration to me.Thanks!

[@MC909Garfield]

OMG !! Thank you very much for this rich Idea !!! one of my motor died after a crash , so I'll use it for props balancing now :) Thanks again , 'cause like Wordreet said : the cheap prop balancers are often not balanced themself ...

[@ARTSTUDIODES]

Just made and tested this fantastic prop balancer. It works great and it's really sensitive! Thanks for sharing!

[@weldslag]

Thanks Dave! What an elegant solution! Now I know why I saved those motors.

[@ThatGuyWhoFanDubs]

Learn something new everyday. Thanks for sharing, I've got about 5 burned up motors just waiting to be converted into prop balancers. Thanks a lot!

[@trobi81]

This is such a great idea! Thank you for sharing this :-) I have purchased three prop balance tools and none of them provide me with an average level of sensitivity for small props - I'm definitely going to give this a go!

[@RealWoutLies]

I have "some" education in industrial engineering. I have been drawing and thinking on how I want to build a balancer. I have the perfect stick-mount motor for this. Thanks a LOT.

[@Drew_TheRoadLessTraveled]

Another fantastic tip Dave. In just 3 years I have gone from crashing and braking small toy helicopters to building 450 class heli's and now I have started to build planes. The A380 1.5m wing span with 4 EDF is my latest project. Most of my knowledge has come from watching your videos. Thanks for all the useful info, I often wonder what you guys did in the days before the internet, lots of experimental crashing and hrs of library books is my guess

[@reubenginsburg2012]

Thanks, it worked perfectly! I used an old Turnigy blue wonder. Very sensitive. One thing I had a problem with was getting the coils out, it took me a minute to take out the bearings. Other than that, it's perfect! Subscribed

[@trappy77]

This works well for car tires if you have a car with rear drum brakes. Adjust the rear bearing to allow for free movement, or if you squeeze the pressure from the caliper. Whatever it takes to get the drag down. I have balanced my own tires In between sets for a long time like this. An old RC plan hobbyist showed me this 25 years ago.

[@iforce2d]

you could be a voice actor, narrate an old western would be perfect

[@marhar2]

Great tip Dave, that thing spins like a piece of precision lab equipment. I love the tips that let me reuse stuff out of old parts!

[@blackmennewstyle]

Nice way to understand balancing blades! It's great!

[@chrissieracki2959]

Great idea! I had an old motor and was looking to balance some props and did not want to buy more stuff to do it.

[@randyneighbour]

great tip now i have a use for all thise old brushless motors. thanks for shareing

[@DevonWayne]

Great video! Lots like this for DJI balancers. I appreciate how much effort DJI goes into balancing props, as I use tape on mine but very small amounts to achieve a perfect balance. I even put tape on the outside of motors and that stops vibrations for video.

[@MyWillyboi]

Great Video Dave and thank you for the tips, will use them in the future for sure.

[@HigherFlyer420]

ive been watching your vids for a while now, but this one got me to subscribe. Thank you for that. :)

[@NarcizoJE]

Great idea, nice tips. Thanks for the video Mr. Herbert.

[@AntoniodaPisa]

Gran bella furbata...semplice ma efficace...complimenti!! Great tricksy beautiful ... simple but operative ... congratulations!

[@kenkentse]

Good video,It's very helpful for me. Thanks Mr.Herbert.

[@pauljohnson5918]

Thanks for your service and Semper Fi.

[@RCPilot204]

Thanks Dave will be making one for sure.

[@Nandox7]

Great idea! With that it even allows to balance with prop adaptors as most of the times they are way worse than the props.

[@spocktra50]

Great stuff Dave as always.I am going to give this a go.

[@felixu95]

It's worth saying that this will work best on two-bladed props - odd-numbered props (3 blades, 5 blades) will be sensitive to the angle the motor's being held at in the vice.

[@c1derpunk]

the music makes this even better!

[@motopest]

Love the vids. You're helping this beginner out!

[@n8lbv]

Vibrator was a good "why the eck didn't I think of it" tip!

[@dpgoverride]

Great video man, I will be doing this next time I replace a motor :) Thanks! BTW you sir have a perfect narrator voice...

[@ramis182]

That's pretty intuitive. I think I'll try making one, great video as usua

[@boomerangfreak]

I got a set of 2 master airscrews from hobbyking for my umx geebee as3x (5.5x4) and the 1 I tried to balance was pretty bad and it took a long time but that might be cuz it was the first prop I balanced and I did use light tape and steel wool to balance (to be sure that I didn't mess up that prop)

[@biglon62]

Thanks for demo of balancing! cheap but effective!

[@63straycat22]

Great, was going to buy a pre built unit but read bad press about them not being balanced and people ruining good props. I'll make one like yours now. plain and simple design Thanks.

[@CheifyRC]

Thanks nightflyer, great video and thanks for sharing your knowledge

[@francoisBonin-phils]

Good idea the vibrator to fight the friction!

[@ysrfreak87]

Great tip as always. Thanks Dave

[@tom321s]

Thanks Dave. Great idea as always. Thanks

[@coriscotupi]

Cool, but.. 1. Must balance the motor first; 2. Thee ball bearing will only turn under a relatively high torque. This method is enough for a rough indication, but it won't have the sensitivity of balancers whose shafts rest on large-diameter discs with 12:1 or more reduction ratio. Not to mention magnetic balancers, that BTW are great DIY project too. :)

[@bessybessy]

Exactly! The friction in the bearings is much larger than friction on the cheap DIY magnetic balancer

[@adrianw2972]

+corisco tupi Totally agree Magnetic balancers are so cheap, so much less friction, and don't need balancing; but this is useful in an emergency. (but I have a box of balanced props) The method of adding tape is 'odd'. Why stick it down and then peel off again if wrong? Touch the tape to the leading edge, only press down if correct. The change in CoG is minimal. Make sure that you balance your motors too, otherwise it's like adding a balanced tire to an unbalanced rim!

[@pauljohnson5918]

Very nice video and great voice,please explain or make video on balancing the hub your way,thanks

[@jbirdaspec]

I really needed one of these, but my hobby funds are dried up. Thank you so much for sharing!

[@tedr35]

What a great idea! Thanks!

[@SlyDawg951]

Great Video, Thanks for making this one, very helpful

[@snoopw111]

Thanks for the class, I will make one, thanks

[@da959]

Another AWESOME video Dave. You really are the MAN. One thing though, how do you know if the magnets are balanced before you throw the prop on? Do you first balance the motor magnet can and then add the prop or are these brushless motors already balanced from the factory?? Just curious. I've seen other videos on how to balance a brushless motor useing a laser pointer.

[@PanayiotisSavva]

Here's a question for you. If the motor bell is not balanced beforehand, doesn't this mean that it will influence how the props are balanced? Do you balance the motor bell first?

[@juniorbaptista6587]

Can you remove bell and let only shaft with bearings...works fine too! I do it myself.

[@jeantessmer6971]

Great video by the way. Thanks for sharing

[@rcpilot9963]

Great way to use spare parts and save some money (for new projects perhaps). Regards.

[@scottfirman]

Horizon Hobby says to sand the heavy side on the back thicker side,what says you to this? Wouldnt tape eventually blow right off anyways?

[@forteleaerieneromane]

this is a really good idea!

[@HyperJoe]

Question: What's the benefit of a single bladed prop? Seems to me a shorter double bladed would be more efficient, single blade would have to be longer to create the same thrust, right? Just something I've always wondered about... ;)

[@markholt17a]

When balancing the blades move tape closer to tip and it get heavier

[@daryl75052]

what if the motor your using to make your balancer is off balance? Do you have a good way to check this possible issue?

[@ryanfonseca3270]

Great idea, what about the motor can tho? On multirotors ive noticed some motors cans are unbalanced and when your looking for 100% zero vibs you need them balanced, So do you balance them at all? this would work for 99.9% of situations out there tho. And maybe the small amount of the motor can balance doesnt effect it at a static state vs 20k rpms....

[@Taskforce1x1]

nicely done

[@Deluxe312]

Pure genius.

[@beverke7]

perfect, and a lot cheaper then some balancers, suppose we all have a stock brushless unused motor somewhere from a plane which we replaced by a stronger and faster motor ;-) I know I have lol

[@rednekk58]

Excellent!! Thanks!

[@MidnightHeli]

If you put it on the leading edge, wind will go over it and it will stay there. if you put on trailing edge or the back or front, wind will grab into the edges of the tape and it will come unglued or just rip off at high rpm.

[@plugtheheliflyer]

Why Did you not do this video a few weeks ago,I was racking my brains thinking how I could balance my props on my 450 Quad. I ended up spending £10 on a slec prop balancer. Ho well you live and learn lol

[@RobinnTech]

great idea!

[@obese1konobe]

Does the tape stay on???? I was sure you were going to file or drill out the heavy blade.

[@samselectronic4548]

thats just awesome!!! thanks

[@BenPortmanlewes]

Very nice, usefull, thank you.

[@EmilyHeathcliff]

Great video!

[@vip3rz200x]

thats pretty pro good work

[@wordreet]

Brill idea Dave! Heh, I guess I'd better hurry up and burn out a few motors. I'm still good with my first brushless at the moment. Hmm, maybe my local hobby shop has one or two lying around! ;¬)

[@nathanskinner8941]

sweet man just made mine thanks

[@NiCadHeliPilot]

If you heard what he said in the video, he said "OLD brushless motors." By 'old' he's implying that the motor was used prior to this little D.I.Y. Havin' said that, if the motor WERE off-balance, it would have shown up in whatever-it-was the the motor used to run in.

[@Ditcha1]

Great Idea Thank You

[@slq5541]

great video!!!!

[@ravenwings7945]

I would buy this

[@jeantessmer6971]

do have any extra burned out brushless motors?

[@MacVision3D]

Thanks for the video ...I use WD40 to clean off the glue works much better

[@Fierag]

i got a dubro as a gift, and i gotta say its very nice, but after trying out this guys method I wish i had the money spent on something else.

[@jonasmannen1998]

can you make totorial how you make your videson i am a big fan of you

[@andreasminninger3246]

Nice Video simple Things ar best in regard of those many, many so called "precise Propbalancer" with heavy unbalanced cheap manufacturerd Prop Cones and bended or croocked Prop Mountachses

[@MartinWeinecke]

Great! Thanks a lot!

[@Trex450S]

WD40 works well too for removing sticky stuff, and it smells good to!

[@GijsBudel]

Good idea! But how can you be sure your motor bell is balanced? If your bell is unbalanced, the prop will never be balanced properly.

[@rcmodelr]

Why do you fold the tape over the leading edge before you have it balanced and know that's where the tape needs to be? Folding tape won't change weight so why not wait with folding tape over prop until after you know how much or where it needs positioning?

[@zyxw12347]

And I almost paid $30 for a little prop balancer today! thats what i get for not subscribing a long time ago!

[@TwistedIntentions79]

You only balanced that one way what about if the hub is not balanced

[@reddeck13]

Ty its great

[@Moeisabeast12]

Dude, quit being awesome :D

[@G56AG]

Great idea for a balancer, but what about glow engines? Glow fuel will easily eat the adhesive for the tape.

[@noodles818]

You must balance the motor bell first though

[@dannegp]

but what if the nut is unbalanced?

[@devinduncan6922]

would be great if you demostrated that the set up was calibrated without any test piece... otherwise we only know that the prop is balanced for THIS setup.

[@MrApru1]

This method obviously requires the motor bell be balanced and that you have good bearings installed.

[@Jimbolina1]

Very nice, but not anywhere as good as a magnetic balancer.

[@wordreet]

Heh, dang! I only have a couple of unusable motors here, and they both have bent shafts! I bought a cheap £3.99 magnetic balancer, and the balancer isn't balanced!! ROFL!!

[@RobBob555]

old motor makes a Shit balancer

[@deltaqnord3103]

pis of shit, Balancing props for over 50 years, hehe..

[@helifanensenada5183]

Thanks Mr. Herbert... I'll try it.

[@MichaelNewton-mydroneclub]

Great video!

[@scottfirman]

Horizon Hobby says to sand the heavy side on the back thicker side,what says you to this? Wouldnt tape eventually blow right off anyways?

[@Ucceah]

that's why he puts the tape on the leading edge, the air presses it tight. personally i wouldnt use vinyl electrical tape though because it doesnt tend to stick well and "creep" over time. sanding is another method i dont like but there are many methods, from drilling tiny divots and sanding, to a mix of 1-minute nail polish and tungsten dust. personally i would propably use aluminum tape and scrape some off with my fingernail, if it was too much. the glue on that stuff is great, and it's pretty thin.
