Well, maybe not slow per-say, but higher quality motors can be reved higher, and can definately handle being geared taller. I dont know the efficiency range of the Medusas, but feigaos work best in the 30-35,000rpm range- any faster and they start to run hot (well, hotter than normal at any rate). One way of looking at the Medusa is to say its better to rev them a little higher and then gear down (torque bonus), than to run them slower and try to gear up too much (higher load on the esc). If you get a 6s esc, then the slower medusa will be great on 5 or 6s, and it appears much better quality than the feigaos, for not much extra $$.
