RE: help please
Yes. kV is a theoretical number and tells how fast the motor will spin without load/propell.
Two identical motors with different kV-numbers would require different propell. The low kV-numbered motor could spin a larger propeller at lower RPM, and vice versa.
Low kV = suits for slowfliers and 3D.
Medium kV = suits for sportplanes.
High kV = Suits for Ducted fans and pylon maybe . Or gearbox.
In general.
kV at 1000 is quite low if you run on 3S LiPo, 230 is low/medium if you run on 10S LiPo.
