These are just what I was seeing from Hobby City/King

motor 1 - KD36-74-15XL 1100kv 45A
on 6s should give up to 24,400rpm and 999 Watts

motor 2 - KD36-60-08L 3000kv 78A
on 3s, should give up to 33,300rpm and 865 Watts

motor 3 -KD36-50-11S 3200kv 60A
on 3s, should give up to 35,520rpm and 666 Watts

My logic would say that a larger motor is required to produce more torque and that the most efficiency would come from motor 1, higher voltage = less amps for same power output, so less heat waste. Yet motor 3 seems to be more efficient spinning faster with less voltage, but maybe more amps.</div><div></div><div>Needless to say, fast is key. But I also like decent run time.</div><div></div><div>I would go for motor 1, but is it going to provide me with enough RPM. Could I just get a prop with more pitch?</div><div></div><div>I could also go to Feigao motors, I would a 10XL or 11XL size on 6s giving 35,000rpm or 38,500rpm and both up to 1000watts?or move down to 8L and 3s? Th more I look the more I am lost.
