SMF681X-ZZ Radial Bearings
1.5 x 4 x 2 Millimeters

I still not used all off previously ordered bearings, but the one I used are much better than the one which I received with my RC helicopter. The fact is, that the original one are not ceramics and doesn't have high tolerance as those I ordered from you, so the increase of the performance is something what I was expecting. One thing I was surprised is how good is working Clean touch. I'm using it extensively now and I'm very satisfied with the result. As my experience with Boca bearings is still very limited, I have to say that it meets my expectations so far, so that is the reason why I would like to order some more.

I would like to let you know that I have received your shipment last friday and I'm very happy with your extremely fast shipping, and even more with your products: I have just installed the bearings on my V120D02S and it's smooth as glass, less noisy and I guess the battery are running longer, I can't wait to install the Blade 130X kit on my 130X. Thank you for your awesome service.

I had put in an order for RC helicopter bearings while I was out of country with the hope to have the parts from you by the time I return. Due to your diligent shipping and handling, the parts arrived right on time for me. Thank you a lot!
