Review on 🔩 Uxcell 2mm x 5mm x 2.5mm Shielded Miniature Bearing - Power Transmission Products by Christian Young

Like my reviewer, I bought these to repair 1407 quads. As the stator and bell were in good condition this should be an easy bearing change. Right? Well I actually went back and bought a second pack after having trouble with the first one. I assumed it was my fault because I didn't know how brittle these bearings really are (have you seen the balls?!). This time I made the right tool to mount the bearings. However, I still had about 50/50 positive results. I went through 4 camps before getting a smooth and calm response. is it just me I do not know. What I do know for sure is that I should have bought new engines right away and saved time and headaches.
