metal sealed bearings or rubber sealed bearings?

[danny the elfman]

hey, sorry to start two topics on the same day. But im about to order some bearings for my mad monkey, but should i get metal sealed or rubber sealed ones? im only going to be using my car once a week on a multi surface race track for around 4 6 min races

Go rubber. In years gone by, the metal shield would have been worth it for the reduced drag but with the power of brushless and LiPo that isn't a problem any more.

The rubber will give the bearing max protection.
