I got my package from FastEddy today and used the new sealed bearings to replace inner and outer axle bearings on my Rlaarlo SBK10 buggy and XTS-S10 rally car. I love my Rlaarlo vehicles but it seems their OEM bearings (shielded, not sealed) are not the best quality.
The FastEddy bearings came in a tube of 10 so I serviced two cars and had two bearings of each type left. I wish the FastEddy bearings had come in a dozen-pack instead of ten. It was my first order with them so I was hesitant to order more. They seem to be OK so I won't hesitate in the future.
In my RC flying days, I ordered a lot of bearings from Boca Bearings. They offer grades of bearings of excellent quality but you pay for that, obviously. For my RC glow engines, I thought the high quality was worth paying for. For RC ground vehicles, I thought I might look for a more budget-minded choice. The sealed bearings from FastEddy were much smoother than the OEM and I'm satisfied so far..
