Steven Kjeldgaard: Very cool and informative video. Great information to get things tweaked
and peaked! Thanks much!
Darran T: Does this work for the dji 22-12 motors that come with the flamewheel f450?
Zbip57: It's possible. Check your props are balanced. That makes the biggest
difference. Then check the motors for balance. I only discovered much later
that one of the three blades of the stock camera mount had cracked right
through. I still had noticeable jello whenever giving full power. It's gone
completely now that I have the Zenmuse H3-2D gimbal with its rubber
nzhuntahr: Would the motor shaft bend from a 50ft fall.Seem to have jello now after
power failure.Landed hard ,took off without checking nuts,nut came off
landed hard again.Check out my after failure vid.Accidently deleted actual
Mitch Peterson: What about the other two motors that use a LH thread Einstein??
Mitch Peterson: The new phantoms come w lh and rh threaded motors.
Zbip57: You guys with the fancy new motors will have to figure that one out for
yourselves. My original Phantom has all RH threaded motors. I don't
understand the need for LH threads. My stock DJI props are keyed and can't
turn on the shaft. Simply snug down the prop nuts and nothing moves. The
newest version has the prop nuts embedded in the propeller. How are you
supposed to balance those props Einstein?
Zbip57: Uh, ya. Those would be the "fancy new motors" I referred to in my previous
post. I posted this video more than five months ago back in April, when
Phantoms had only RH threaded prop shafts. You'll have to figure out your
own method for balancing the new LH threaded motors, and for balancing the
new-style props with the nuts embedded in them.
Pat B: Thanks for the reply, every thing that can be done to help balance is good
thing. The aluminium tape idea is cool.
Zbip57: Well spotted. The centre shaft is slightly bent on this motor so the whole
bell housing is off centre. I don't know if it was like that right out of
the box, or if I bent it when I hit the flagpole in 'My First Phantom
Crash'. But that's certainly what is causing the imbalance on that motor.
One of the other four was perfect. One needed only a tiny piece of aluminum
tape to balance it. This one though needed two fairly large pieces of tape
to get it to balance. It made a huge difference.
Pat B: Interesting but the motor is out of round or not centered. Look at the
"top" as it's spun, and the shaft end on the balancer. It's wobbling and
that's not due to balance.
Zbip57: If I can figure out how to put it back together :) I can still use the $15
tool as a centre punch, whereas if I bought just the $5 piece I'd only use
it once to balance the motors.
Willard Jansen: excellent! Thanks for sharing
Zbip57: -Disclaimer-: No guarantees whatsoever offered or implied. Your mileage may
vary. Batteries not included. Never run with scissors. Always look both
ways before crossing the street. If you don't always look both ways, at
least make sure you're wearing clean underwear before leaving the house.
Just because I had success using this balancing method doesn't mean it will
work for everyone. Always remember to send flowers to your mom on Mother's
Day. (Thanks mom, for the underwear advice.)
Jaime B: This is brilliant. Thank you!
alex laur: Hi friend ! How are you?...Great work !
ghosttjr2: I was told never to run a brushless motor without load?!!?!?
Zbip57: Any tips are welcome. Which piece under $5 would you suggest from the
vemotorsports: And thanks for a well put together video! Worked perfect on mine. Thanks
Tommo Guernsey: Great tutorial best I've seen
ghosttjr2: maybe if I put a bearing on one side in a clamp I get the same result as
with you're balancer.
topgunm: This is a good idea in theory, but it didn't work for me. I did this and my
motors were completely out of balance. I used the Dubro balancer.
Zbip57: Why can't they be run without load?
Zbip57: I wish I'd taken a shot of it dancing all around the table before I
balanced the motors. It made a HUGE difference. The tube is lying on the
table at the bottom edge of the last shot. It didn't even start rolling on
the table. No vibration at all. :)
Zbip57: Thanks! That's excellent news. I know a lot of my American friends were
looking for a suitable equivalent.
Neavissa: not bad not bad. I have the same balancer, but it stood around for a while
collecting dust! Now I feel like it is not as smooth as it was! Any ideas
on how to get it going again?! Thanks!
Zbip57: If it is out of balance it will always stop turning with the same heavy
side at the bottom. Once balanced it will stop equally in any position.
Dany Thivierge: Wow great idea! I like that. Not too difficult to do and will help a lot.
Wonder if you can put a laser pointer on the arms to see how much vibration
you have left now. (and Before/After shots would be great!) Good work! Dany
Steve myob: Funnily enough it's because they can vibrate to the point of generating
excess heat, 30 seconds isn't going to hurt though :-)
SHAWNS High Altitude Media: Nice video! I found some dji bearing upgrade kits on ebay . These ceramic
bearings thrust washers and retaining clips are a great improvement on
these motors .And reduces the harmonic resonance to improve FPV range and
topgunm: Such a great tip! Thanks for sharing! I thought I had balanced the motors,
but the 2 motors I have done so far needed 4 strips of electric tape to
balance them out. I can't wait to see the results. Balanced motors,
balanced props, upgraded bearings, Iso-mount. It should be jello free now!
Zbip57: Whatever system you choose, it's definitely worth it and not foolish to try
to improve the balance of your props and motors.
arakuzi: Another alternative is to "slowly" drill 1/2 way the heavy side to balance,
not sure what may happen if the aluminum tape come out while flying.......
Phil Wright: Very nice! Don't suppose you have the diameter and thread pitch handy of
the motor shaft threads. That center punch isn't available in the US Home
Mark Crandall: But I do like the idea and balanced is always better. Nice work. Why buy a
$15 dollar tool for the threaded piece? Why not go to the hardware story
and by just the piece for under $5? Isn't the motor shaft a 1/4-20 thread?
I'm too frugal I suppose.
vemotorsports: As Aqngler said below, the Procise is only in Canada. Search Empire level #
27203. Amazon., Tools Plus in the USA.
Al Me: Okay, that makes perfect sense. Thank you!
ghosttjr2: without load can overheat the motor or something, but doesn't matter I
liked the video, only thing is I have a magnetic balancer and so I can't do
this : (
Ron Jackowski: Great Video. Shows in detail how to balance your motors before balancing
the props. The Pocket Auto Punch shown in the video is only available at
Home Depot IN CANADA! However, I found it at Menards in the USA
manufactured by EMPIRE. I hope that this saves a lot of time looking for it
as I did, The 6mm thread screws right in the one side of the barrel.
woodryan: thank you for this video. I was trying to figure out how to figure out how
to balance my motors!!!
Al Me: Great video. I'm confused about one thing: After you balance them, you
twirl them and say "Perfect" based on how they stop, I presume. What
exactly is it you're looking for to know the motor is balanced? What shows
it is balanced?
Edward Bernard: Very simple. WAY easier then these fools using there iphones and lasers.
