The SunnySky 2207 2100KV motors can deliver over 400W of power and generate about a Kg of static thrust but will you see *any* benefit if you simply swap out the existing1806 motor on your miniquad and use the same old 5x3 GemFan props with this motor?
The answer is.... no!
The reason is that the GF5030 props just won't load this motor up enough to extract any more power than your 1806/2300KV motor is delivering.
To really get the most from the SS2207 motors you need to run a prop that loads up the motor far more. A 6x4.5 prop and preferably a 4S battery are what's really needed.
