heli louder

I'v installed a KDS 3800kv motor in my blade 450 3d,and i'v noticed that it is quite a bit louder than with the stock motor,Everything seems normal as in the main gear mesh and I was warned that the motor is more powerful than the stock one.Could this explain the difference in sound?

I'm thinking it could just be louder because it has more power, just double check the gear mesh to make sure..I've come to find out that you should be able to move the main gear just barely, without the pinion moving at all..If you can't move it a tit, chances are it is too tight.

Noise usually comes from more rpm, poor gear mesh, smaller pinions, and motor balance issues.
