The Arc brushless motors offer excellent efficiency and durability.  This motor will give great performance on a 6S battery and extreme performance on a 8S system.  If using a 8S system, the motor needs to have very good airflow and cooling.  This motor will work with fan units like the HET 9305, 9305-700, Wemotec Midi-Fan and the Schubeler DS-50.

FOR MORE INFORMATION: REFER TO THE "ELECTRIC SETUP GUIDELINE" ON THE HOME PAGE TO HELP DETERMINE THE PROPER SET UP FOR FAN, ESC, MOTOR AND BATTERY.

In Midifan PRO on 6 cells the motor produces 5.7lbs/2.6kg thrust at 1580 watts.

WARNING: Operating the motor outside of the specifications listed above can either damage the motor, battery or esc. It is important that these components are set up properly. Failure to do so can void the warranty. It is strongly encouraged to use a Watt Meter to test the watt and amp performance when setting up a new system. If the output is above the factory recommended specs, then it needs to be adjusted by the esc. The timing and throttle settings on the esc can help to set the appropriate levels.
