lol, I was calculating the rpms based on lipo voltages. RPMs using LiFe cells will be even less, and likely more of a problem. Generally, we try to shoot for ~35k rpm. So, if you are using 3s lipo, that's ~3100kv; for 4s lipo, that's ~2300kv; and so on. Just divide 35000 by the voltage you want to get the motor kv, then just pick the motor that is close.
