RE: picking the right electric motor
like 785 said, Kv depends on your voltage. What is the Max [cell/volts] your ESC can handle? Then see what Kv you need to spin about 30,000rpm (Kv = rpm/volt)
If you run the 752Kv motor, you are going to need to run like 10s-12s (37V-44.4V nominal)

RE: picking the right electric motor
hello everyone have question on battery s rating I have a swordfish pro 300a esc with 4s - 15s lipo rating I need to know if its ok to use two 7s lipos in series or is that too close to the max cell rating for the esc, because that would give me 14s . thanks
