‘Rates’ is the term people use when they describe the stick input sensitivity when flying a quadcopter. ‘Rates’ is used because it describes the ‘rate’ of rotation at which the quad moves with a given input.

I highly recommend playing with this to find what suits you – it can make a tremendous difference on your flight style. A more gentle curve often aids a smoother style, and higher rates can provoke more aggressive flying style. Fly whatever you are comfortable with – but note that high rates does not mean you are a better pilot…set the full stick rate to roll/flip at the speed you feel comfortable with then set the curve that feels managable. You can adjust the curve by using expo, or balance the RC Rate (linear) with Rates (curved at the end)…. 

Most people fly using thumbs or ‘hybrid pinch’ (where your fingers rest on and guide the sticks as well as thumbs). Thumbers tend to have more expo to help smooth out stick movements and give more ‘resolution’ to help accuracy, because thumbs alone are not the most dexstrous digits…The combination of thumb and finger with the hybrid pinch method helps with accuracy, and thus with the rates you can take more mid stick sensitivity. However, using just thumbs, it can feel freer for fast flick moves which are becoming popular in freestyle, so both methods have their pros and cons.

The reason I bring up thumbs and hybrid pinch is because below are some starting points for the three major flight FW for freestyle. I fly hybrid pinch and thus have a bit more sensitivitiy mid stick. If you fly thumbs feel free to add some expo, but below is a reasonable starting point!
