Perfect prop balancing shaft for Hubsan 501S Props

Perfect prop balancing shaft for Hubsan 501S Props
This is a very well machined prop balancer that I purchased exclusively to use with my Hubsan 501S self tightening props. One side fits the CW and the other side of the shaft fits the CCW threads. It's made by Du-Bro so it works perfectly with their prop balancer. It's a great product from a trusted brand and now I check every prop I get.

5.0 out of 5 stars Must Buy Tool for Your Quadcopter/Drone
Reviewed in the United States on February 6, 2017
Style: 5MMVerified Purchase
I have a Hubsan H501c and used this tool to balance my 5mm shaft propellers.

I was very pleased with this tool since I found that it is machined very well and "true" - if you try to buy some cheap knock offs you may end up buying an unbalanced rod which will only produce unbalanced props. One side of the rod is for the propellers fitting clockwise and the other side is for propellers fitting counter-clockwise. Just remember to screw your propellers COMPLETELY into the rod for best results (give it about 1/8 inch of turn after the propeller is fitted onto the rod). If you do not do this you will get faulty readings on your balance results.

Another tip - if you want to balance your props the easy way, perform the prop balance with scotch tape and prop hub balance with hot glue. Some purists will sand their props and use CA (super glue) to balance their hubs (you have to buy CA kicker if you want to use CA or else you'll be waiting forever to apply additional coats) but I found tape + hot glue is way faster and far less messier.

Anyway if you want to minimize jello/vibration on your drone videos and want to get long efficient use from your motors then you need to buy this!

5.0 out of 5 stars Balance your props
Reviewed in the United States on March 8, 2018
Style: 6MM QuadcopterVerified Purchase
I bought my first Phantom 2 back in 2014 and now also have a Phantom 3. Sometimes when I need to discharge the battery (and don't have access to my discharger) and I can't actually fly the drone I clamp the drone to a workbench and run the drone until I get the battery to storage voltage. Once when I was doing this I noticed at certain rpm's the drone would really vibrate. This got me thinking about the props being out of balance. I have been into RC (cars) for decades and I happen to already own a Dubro prop balancer. I needed the balancing shaft so I could test my props and ordered the Dubro 6mm balancer. It arrived and it is very well made and has the CW and CC threads, one on each end so all the props can be balanced. After checking my props I found two were way out of balance and was causing the vibration. Excessive vibration will wear out your motor bearings and stress the motor mounts, so I highly recommend you have your props balanced. I have found the Dubro products to be of high quality and I recommend them.

Reviewed in the United States on April 30, 2018

Fits my 3DR Solo propellers and thus I can now balance them.

Clockwise threaded on one end and counterclockwise on the other with a machined indicator on one end to tell you which thread direction that end is.

Well made and well worth the price. It is important to balance your propellers to prevent vibrations that can cause bad video or photos. Also it lessens the wear and tear on the quad's motors.

2.0 out of 5 stars Poor Quality Left Hand Threads
Reviewed in the United States on June 14, 2020
Style: 5MMVerified Purchase
Very disappointed with the first one I received. Could only spin the left hand drone propeller on about 3 threads then it would continually get tighter and would not go on all the way. Returned and Amazon sent me a new one and it went on about 5 threads and was very tight all the way to the end. When I first received the new propellers I installed them on my drone and they spun freely all the way down. The right hand threads would spin all the way down to the end like they do on the drone. Would like the seller to contact me and let me know if I can get one that works like both the drone motors and spin all the way on.

Hard to find balancer rod for Hubsan props. Not the cheapest thing in the world, but worth it if you are at all 'serious' about your H501s.
