4s = 14.8v x 2200kv = 32560 RPM
5s = 18.5v x 2200kv = 40700 RPM
6s = 22.2v x 2200kv = 48840 RPM
Or am I way off the mark here?  |
yeah...i think he was just using 4.2v instead of 3.7v
3s X 3.7 = 11.1 vs 3s X 4.2 = 12.6
but remember the max rpm of a motor is still limited by the quality of construction and size of the motor. In this case, we are talking about neu motors which have a max rpm
recommendation of 60,000rpm. So take your max rpm and divide by your voltage to get the max kv rating.
60000 / 22.2 = 2702kv
now is this the end?....nope
while you CAN run the motor to 60000rpm, it doesn't mean you should. Running any motor at its max will most likely cause heat/efficency issues.
and here is where brian and others could probably school me...
...i have heard that its best to run these motors in the 40000-50000rpm range for best efficency.
which is why I bought the 1515/1Y to run on 6s (22.2 X 2200 = 48000rpm max) Only time will tell....
