what advantages are we seeing over the fantastic stock Revoslot motor?

Way more power than most brushed motors at only half the size (or less). If that's what you want. Not everyone wants their Scalex VW Beetle to run as fast as a winged car. It tends to leave Beetle imprints on the drywall at the end of the longest straight. 

I've been running all sorts of brushless motors in my RC planes for years. It's considered old tech already.

Like a moth to a flame. Some people like to go too fast and break cars.
