RC Prop Propeller Balancer for RC Helicopter Multirotor Airplane

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

The balancing shaft is bent. Completely defeats the purpose. Just got the second one... Also bent. I wonder how many people out there are running terribly unbalanced props because of this

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.

Great product

Balancing you props before you fly is mandatory if you want your RC plane to perform at its best and last a long time. It also improves reliability. At this price the balancer is a no brainer.

It is impossible to balance anything on a bent rotation shaft. Two badly cut pieces of clear vinyl tubing is what's supposed to hold the spring and mounting cones in place on the balance shaft. You can't apply enough pressure on the mounting cones because the tiny piece of vinyl tubing just slides back. This so called "prop balance tool" is actually dangerous and could lead to crashed aircraft and injured bystanders. This is a lawsuit waiting to happen! I pay for Prime mainly to save money on shipping costs. Amazon should automatically allow prime customers to print shipping labels at zero cost for damaged items. However Amazon sucks at some things. Amazon customer service is a sad joke. Endless automated menus beforeyoucanspeak to an actual human customer service agent and customers have to pay to ship damaged products back to Amazon. In my case, I have to drive 12 miles to the nearest drop off location. This poor quality propeller balancer cost about $18 after tax. Driving 12 miles to return this thing isn't worth it. So I get stuck with a piece of junk that doesn't work and Amazon keeps my money. It's time to cancel prime and boycott Amazon!

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.
