KV Comparison of Cheap and Popular A2212 Brushless Motors. Which KV For your Airplane.
A BLDC (Brushless Direct Current) is an electric motor powered by a direct current voltage supply and electronically commutated instead of by brushes like in conventional DC motors. The brushless motor thrust is made of aluminum and plastic materials, which can provide strong power. BLDC motor (Brushless Direct Current) thrust, high efficiency and low power consumption. BLDC motor can be used for many kinds of vehicles and engines such as rc airplane, rc car, rc boats, propellers, and rc jet engines & rockets etc.
These are static thrust tests. None of the cut propellers have been tested in-flight.
In-flight performance could be different, vibrations are quite possible if props are not cut with equal length. It'll be interesting to see if GF5030x3-4030x3 becomes a good choice prop to use since those don't do well on 4S-2300KV with the larger 2204 motor. They end up wobbling too much.
Only thing I did notice with the SZ6040-4040 were vibrations, I tested 2 props. I don't know if it's because of the very wide shape of the prop at the 4" mark that causes lots of turbulent air or my prop-cutting skills, so that's something to keep an eye on, as excessive-constant vibrations will wreak havoc with motor bearings
