Goolsky Tru-Spin Prop Balancer for RC Helicopter Multirotor Airplane

EXCELENTE ARTICULO.100% RECOMENDABLE.

Working Great as Advertised.

The prop shaft had a very slight curve, about 1-2 thousandths (less than a hair thickness), easily fixed by supporting the ends and pressing (hard) in the middle.Over-tightening the nuts that secure the balance disc assemblies to the vertical rods will compress the plastic housings and prevent the discs from spinning freely. The nuts don’t need to be very tight at all, just snug them up enough to prevent slipping but not enough to cause the discs to bind.After figuring these two quirks out I easily balanced a folding prop, and determined that Uxcell plastic props are close to perfect out-of-the-bag.Other reviewers have mentioned missing parts and improperly threaded nuts or rods. If you get one that suffers these problems, contact the seller for replacements, or just return it for another one.Overall, it works fine if you’ve got a hobbyist’s mechanical intuition and tinkering skills to get it set up right.

The specific item that I received was not functional as shipped. The tubing that is supposed to hold the springs and washers in place was approximately 1/4” long for each piece and did not have enough friction to hold any tension in the springs. Additionally, the aluminum hubs had sharp edges and did not spin freely. I was able to solve both of these issues with some work and parts that I had in my shop. If you are looking for a prop/wheel balancer that works out of the box, I would look elsewhere since this item simply did not function as it was sent to me.

To small for most prop spinners. Good for props but needs better plastic sleeves that hold everything together. I use striped insulation off of small wire.

came with bent balancing shaft making it unusable. Sent three emails to customer service with no answer. Had to buy Du-Bro replacement so I could use it. Should have went with Du-Bro in 1st place. Wouldn't recommend to anyone.

Can’t get it to work. The rubber hoses do not lock it in so was kinda a wast of money for me

What a great prop balancer. If you’re into RC planes or any flying aircraft this is the must have tool. Easy to use. And the quality of the product is fantastic. I give this product a five star.
