Get increased cooling with a bonded heatsink. A bonded heatsink transfers the heat
from the motor to the air better then just a slip-on heatsink. The heatsink is permanently
attached to the motor so it won't slip off or move and there are no air gaps that
reduce the effectiveness of the heatsink. The heatsink is positioned in the middle
of the motor where the most heat is generated to provide the best cooling possible.
NOTE: Not recommended for motors used in EDF (i.e. Ducted Fan) applications!
