Hobby Fans RC Prop Propeller Balancer for RC Helicopter Multirotor Airplane

Easy to assemble and very sturdy. Works great for my RC boat props

Balancing shaft is bent right out of the box and does not straighten. Useless essentially. Large turn wheel needs so much graphite powder to spinn smooth.

Great product

It was easy to assembly by just looking at the picture, so i structions are adequate. My balancer came with a warped shaft, so minus one star for that. Since I'm not relying on that shaft, I can and did static balance props with this balancer using my own shaft, so it works good enough for me and a good buy for the price.

Works great, much better then expected and much cheaper then the $50 one from the DuBro. Yes! I would recommend this.

Save your money and buy a more expensive brand. Since the main balance shaft arrived very slightly bent, the unit always reports that the prop is unbalanced. This is a manufacturing defect, either with quality control at the factory or poor packaging that let it get damaged in transit. Could tell that the shaft is bent because its readings aren't consistent. There is a discoloration on the shaft, which always settles pointing upwards, regardless of the prop's final orientation. Proves that the imbalance is caused by the shaft not the prop. The bend isn't visible to my eye, but in addition to the above behavior I can hear the bend by rolling the shaft on a very flat surface. The rest of the construction seems adequate. Trying to salvage the situation by buying a replacement shaft from DU-BRO.

Yes it worked. The two silicon tubes it uses to keep the centering bits pushed towards each other need to be stronger. That said I was using it to do 20 times what it was designed for. All is forgiven for this small short coming since it worked so good! Look for pic, you can see what I mean about silicone tubing. I used electrical tape cut thin.

Pkg arrived fast, and yes it looks exactly like the Dubro version at a much cheaper price, but it came with silicone tubing that fits loose so you can't set the cones with any kind of tension( granted not that big a deal BUT the balancing shaft, a critical piece to making this item work right is warped. No way to accurately balance anything with it. No way to contact the seller to get a new one.
