The Scorpion HKIII-4020 motors follows in the footsteps of the HK-4020-1100 model which re-wrote the book on power for helicopter models, the HKIII-4020-1100 motor features a new patented rotor can that provides several benefits. First, it is thicker for more stability at higher speeds, and this also helps to retain more of the magnetic field for higher efficiency. Second, the outer surface of the rotor can features a new spiral rib pattern that increases surface area and helps to move air around the motor for increased cooling and lower operating temperatures.
In addition to the mechanical changes to these motors, changes in metalurgy in the stator assembly and rotor can have increased the overall efficiency. This allows the motor to handle ...
