My D5 11x1 brushes lasted me about 3 packs before the tips turned purple...yes the tip turned purple
I like mod, I can't afford a new motor (I want one)
I'm getting some hodge-podge mod within the next week (week is a long time) "old 12x2 can with a 10x2 Arm...probably needs a rebuild" - can't beat the price of free. Maybe I'll pop the 10x2 arm into the D5's can.....
I'm bored....I just needed to write something along the topic
