So I'm fairly new to brushless setups. I just got a used Reedy 3300kv setup off "the bay." I can't see any way to get the motor apart (no through, bolts or anything). I'm the kind of guy who likes to take used stuff apart and inspect/rebuild it before I use it. Should I just shoot some motor spray through it, oil the bearings, and call it good? Any other things I should be looking at?
