imho brushless is boring *dons flame suit*

jokes aside - re: RC / hobby grade oil... wouldn't an ATF or full synthetic gear oil be just as adequate if not better? I've never understood RC marketed stuff which are just re-labelled/re-packaged items easily available from other industries. i.e. engineering / automotive / common hardware

My method of cleaning BB is probably overkill but works very well. Quick wash with toothbrush in kero, then 15 minutes soak in clean kero and ultra sonic bath, flushed and dried + re-oiled.

I'm probably not going to bother with my current motor bearings as they were second hand and have clearly been abused + never cleaned and oiled.
