Main Motor Care and Installing the Optional Main Motor Heat Sink
The 180 motors used to power your Blade™ CX2 are of the closed endbell variety and do not require any special
maintenance. We do, however, suggest that you allow the motors to cool to near ambient temperature between
flights/battery pack changes to prevent accelerated motor wear due to excess motor heat.
You will find the performance and life of the 180 main motors to be very good, however, installation of the optional
Main Motor Heat Sink (EFLH1208) can help to further improve motor cooling during flight, resulting in improved
motor performance and longer motor life.
Installing the main motor heat sink takes only a few minutes following these steps:
• Installation of the main motor heat sink will require that you to temporarily remove the right-hand main motor from
the main frame. This is easily accomplished by removing the two motor mounting screws found on the bottom of
the main frame.
