DuBro Tru-Spin Prop Balancer - Black (499)

Great Balancer, but Needs Something...

I have used this balancer to balance a large number of props, since receiving it. It's a great design, sturdy built and works great. It is especially useful in balancing larger, quadcopter/drone props like Phantom and Chroma.
The balancer comes with a universal balance rod, that fits a wide range of prop sizes. However, when balancing fixed-nut props, like Phantom, you will need a special threaded rod, specific to the prop. Since these props will not allow the balance rod to pass completely "through" the center of the prop, a special rod is needed. Also, I wanted to balance even my small, lightweight props, like on a Syma X5C or other toy-grade quadcopters. These cheap props are typically very unbalanced, but have a very small shaft hole. This is a problem with ANY balancer, since no balance rods exist for these small props. I have made my own, using a variety of material, including bicycle spokes. Once you make something fit, the balancer works amazingly well for these small props as well. And it makes a BIG difference in performance, even on the toy drones.
So, this is a great balancer, that will work on most ant prop. BUT, there are not enough balance rods available, for the large number of aircraft out there. This is a problem that shouldn't exist. Yes, you can make your own, but not everyone has that ability and wouldn't it be nice to have them available for this great balancer.Read full review

Nice balancer BUT

This is a great balancer after I worked on it. Two of the threaded rods would not accept the nuts and lock nuts. Luckily as a retired machinist, I knew what to do. After wire brushing the threads on my bench grinder, they fit ! The rest of the balancer seems to be high quality.
Don’t know what happened to quality control with this one ? The average person would probably have to send it back. Hope this was helpful !

After Dubro read this ,they contacted me with an apology and sent two new post, free of charge ! Thanks to Dubro !!!Read full review

Get what you pay for.

This is the prop balancer that I recommend to others asking for suggestions. It's a bit more than some of the other models available, however it is fully adjustable to accommodate the larger props, threaded nut props (IE DJI, 3DR, etc). I've used this piece of equipment to balance phantom props, 5 and 6" props, as well as 13" t-style. A twist of 4 easy grip nuts allows you to change orientation for the threaded nut stype props, raise for the longer props, or even take down for easy storage out of the way. It compacts down small enough to fit in your field box if you want to take it along. Phantom operators will need to purchase a short threaded aluminium rod in addition as the included rod is intended for pass through use on standard prop designs.Read full review

Very good balancing tool.

This was really easy to use to get both spinners and propellers in balance with a high presicion. I balanced my spinner for my FMS P-51D with the propeller blades mounted on it after I weighed the blades individually on a gunpowderweight, and now there are no more vibrations in my plane whatsoever. It's easy to assemble right out of the box, comes with a very understandable instruction sheet, it's easy to use, and seems stable and accurate.
Very happy with my choise of this tool from Du-Bro.Read full review

Awesome Prop Balancer

Had an issue with a slight vibration in my Drone, was able to determine one prop was out of balance with this product. Easy to use, I balanced the prop, an now no more vibration. I now test every prop, even if the manufactures says if balanced, I don't take their word for it. This makes it very easy and quick to test.Read full review

one the best blade balancer money can buy

Saved my helicopters from vibrations that can affect it flighty performance. This is made by Dubro in the USA. Very versatile as it can be adjusted to the lenght and height of the blade assembly and as second step would attach the main rotor blades itself. Highly reliable for double and multi-rotor roto blades. An essential tool the helicopter and fixed wing hobbyist. It's entertaining to see if the blades and rotor head are in perfect balance. This balance had been for years.Read full review

works as described

I bought this product because my plane a F4U Corsair 1450 mm has a 14.5 inch 4 blade propeller that when I started the motor the plane would vibrate and jump all over the place. Using this balancer my plane now doesn't do that. It was quick and easy to see where I had to make the changes to my propeller blades.Read full review

It's the bomb

Asembled and worked perfectly. Almost bought cheaper balancer, glad I didn't.
Accurate and repeatable with an ingenious mechanism to reduce friction on the balance shaft.
I used the "sand-off-material-from-the-heavy-side" method to balance drone props and must have built-up a static charge; my prop would move as my hand approached the prop.
Very sensitive instrument. Made in America. Can't say enough good about it.Read full review

Gliding on air

This thing is smooth as silk . The rotation is so sensitive , the slightest imbalance on a propeller set's it tipping .
Multiple set up adjustments makes this the most universal blade and propeller balancer I've ever used . This is by far the easiest thing to use with simple illustrations to follow by . I highly recommend this prop balancer .Read full review
