1515/1y vs. 1515/2.5d

Confusing & interesting, yes! I would have thought gearing down a high kv motor would be better, but then again some motors are said to run better if overgeared....

I like the idea of using the smaller 1512 motor since it would be more than powerful enough for my ideas- for you though the 1515 2.5 sounds like a nice motor.
