Hobby FansTru-Spin Prop Propeller Balancer for RC Helicopter Multirotor Airplane

Thanks

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.

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

Worked fine

Get what you pay for ...shaft was bent.... I started a return but decided to keep it and just buy a new Du-Bro 959 shaft Lets see how that goes... I knew something was up when I would turn the shaft 180* and the balance would follow it..
