Using this assembly, our team successfully repaired a quadcopter that had been gathering dust for months. We were amazed at how easy it was to install and get the drone back in the air. The product is versatile and fits a range of drone motors, making repairs simple and cost-effective. The only downside is that we wish it came with more detailed instructions. Overall, this is an excellent product that exceeded our expectations. Highly recommend for anyone looking to restore their quadcopter!
