Case in point; I like to bash more and want that instant diff-chewing power whenever I want.
Also, it might depend on which ESC you are running. From conversations with Mike, the Tekin motors like low rpms when running sensored. Just gear up (within limits) for speed. But, if running a sensorless, low motor rpms means even lower rpms on take-off and may cause cogging at startup. So, for pure sensorless ESCs (like the MMM), a higher kv ~2000-2200 might be better.
