Feigao's do not have segmented rotors, they are simply made from multiple set size chunks... XL is three pieces, L cans are two, and S are one piece. IIRC.
A segmented rotor will have small thin magnet 'segments' that make up a larger one... those of you that don't know what it would do; a larger magnet segment will have excess 'eddy currents' caused by high frequency switching (from ESC, both the carrier frequency: PWM, and the pole switching)... now when you reduce the size of these pieces, you reduce the eddy currents, thus less heat is created. A 'sintered' rotor is the best for this as the 'segments' are very small, particles really... so you can see how this would create the least amount of heat created by eddy currents.
