The FP's thrive in conditions that require the high power in a small space and high RPM's.

They are good for things like running a ball roller system, where you need the high RPM and you can keep it running at that speed. It's also helpful that they have far and away the greatest power the weight/size ratio of any motor in the kit so packaging them is easier.

In fact, anytime you need to keep something spinning at a fairly consistent (high) speed is a possible FP use. It's not that a CIM motor can't do it, but they are probably better placed on a drive train or arm which will require more slow speed high torque operation.
