More MaxxFan Motor Problems - Can we upgrade to Brushless?

Having again needed to completely tear apart our MaxxFan ventilation for the 10th+ time, I figured I'd show the problems you might have with a MaxxFan and how you might solve them. I also go to great lengths and cost to get a drop in Brushless Motor to fix these motor and controller problems once and for all, only to fail miserably.
