You probably need to do the throttle ranges for each motor, most new people don't know about that. The motors and ESCs need to know the range of zero to a hundred percent on your radio's throttle stick. If you haven't done this it's very easy. One at a time, plug your ESC wire directly into your throttle channel with the throttle all the way up then power up your quad. When you hear a beep, immediately set the throttle to zero - that's it! You can test it by throttling upon down, masking sure it goes full power at the top and stops at the bottom. P.S. if you find your throttle is reversed when you plug the ESC into your throttle channels, i.e. so full throttle is at the bottom, just do the same as above but remember the throttle is upside down so full throttle is temporarily at the bottom, it will still do the job and work fine when you plug it back into your flight controller. Here is a video that shows some guy doing this:
