My son can testify that brushed maint. sucks. He's waiting for brushes to show up for his RC while I'm having fun running my BL. We order most every thing on line as the LHS is 2.5 hours away. Even at that they carry minimal parts especially brushes as most of the guys who run there go BL.
If I could only draw what I see in my head, then build it, and finaly get to play with it...
