losi ten bearing question??
 

I have a losi scte and was taking it apart to clean. I came across a few bearings that are rubber sealed. Just wondering as regular maintenance when do the bearings need to be replaced and how to tell they are going bad?

Roll them to see if they feel gritty. If they do then its time to replace.

+1, If they feel gritty its time to replace them. Best place to pick up some replacements: www.avidrc.com. Only $1 a bearing for the Revolutions and they are a high quality bearing.
