Hi, does somebody can tell me if those bearing are good?
Summit RX8/1550kv-Slash4x4 MM2/2400kv Twin-V Merv.
Don't know but can recomend Avid wich I use only and RC Boca.
I use AVID Stainless Steel Ball Bearings and they are great! They were $2 each so I replaced almost every bearing in my car for $30, and they don't have any problems. They are good quality, and I would recommend them to anyone. Just clean them regularly and they will be fine. If any seize up at any time, they are only $2 to replace anyways so it's a great bang for your buck. It just says these are chrome, so if it wears out quickly, you will see rust and seizing up more often. +1 on the Avid bearings
