Yup, this is seriously the biggest problem I have had with all of my brushless motors is the bearings. Rtr brushed motors aren't too bad because they have bushings, but the brushed motors that have bearings in them also suffer from this issue and it is worse because most of the cans aren't sealed and are completely open, I've actually killed a freshly rebuilt brushed motor in 1 pack from the dust getting in itYes, the stock bearings (in most if not all motors) leave something to be desired. They are not sealed which let's dirt and moisture get into them and they fail fairly quickly. There may be a few out there that are an exception.
You cant source a new Arm for the RTR motor. Get a new motor and if you are motivated enough get a set of hybrid sealed bearings ( ABEC 3 minimum or even ABEC 5's best ) to swap out the OE bearings. I believe Jims Bearings has them. I noticed Castle motors use quality bearings like these as standard. The Hybrid Seal bearings have a seal on one side and metal shield (unsealed side) on the other. Install the bearing with the seal facing out. Dirt will stay out. I would lube the new bearings well before installing.( lube the metal shield inner side) Then just watch your temps a little better.What’s the recommendation? Do I buy a new motor and get better bearings? Can I rebuild this one somehow?
Thanks
