IMO, I don't know what the fuss is all about. Yeah, 2200kv is a
bit high for 6s, but if you don't want to go that fast, just gear down. For a given battery voltage and vehicle speed (mechanical load) a higher kv motor geared down will draw just as much current as a lower kv motor geared up, and runtime will be about the same. Any efficiency gained by using a low kv motor is lost by gearing high to compensate for lower speeds. Again, this is for a given voltage and vehicle speed.
Plus, spinning a motor a little faster and gearing down is better for the ESC because it has enough rpms at low speed to get adequate back-EMF pulses. A too-low kv motor geared high will spin too slow at low vehicle speeds and may produce cogging. Of course, this theory holds true for better motors like LMTs and Neus (which the CC motors are based off of) - you wouldn't treat Feigaos the same way because of their lower rpm sweet spot.
If geared down and it's still too fast, set the throttle EPA down a tad. Once you get bored with that speed, increase it back up to 100% and you'll be happy again....until max speed becomes boring.
