JP Hobby 70mm 2250kv 4-6S CCW EDF

The JP Hobby 70mm 2250kv 4-6S 12 Blade CCW Metal EDF offers great durability with a metal fan unit that offers excellent performance.

All JP Hobby fans and motors are test run at the factory to ensure that they are in proper operating manner before being shipped out. The fans are put through a series of tests to ensure that they are operating as intended. Be sure to reference the instruction manual for proper motor and esc program settings.

FEATURES:

The shroud acts as a heat sink, removing heat from the motor. The motor and fan unit comes assembled and balanced from the factory. This design creates a more efficiently running motor and will provide peak performance while extending the lifespan of the motor.

Jingpin Hobby uses High grade aluminum alloy material for highest rigid structure and lightest weight. The aluminum shroud body heat sink and design assures your motor will run cooler. The high rigid structure design is capable of running up to 88,000 RPM to produce extremely high efflux velocity for maximum speed and efficiency. The anti blade flying out design, keeps the blades be safely in the shroud and without damage to the aircraft. It is the best replacement for your plastic or carbon shroud if you want to have a safe EDF fan.  Each metal blade is precisely made of high grade aluminum alloy to generate jet airflow. Every blade has been tested for 8 hours of metal fatigue test as well as in the dynamic balance machine for calibration, making it a better and safer user experience for every edf fan.

BUILDERS NOTE: REFER TO THE “ELECTRIC SETUP GUIDE” ON THE HOME PAGE TO HELP DETERMINE THE PROPER SET UP FOR FAN, ESC, MOTOR AND BATTERY.

Electronic Speed Control Notice:  The JP Hobby edf units have a high pole count in their motors.  It is strongly recommended to use Hobbywing or JP Hobby esc’s as they will provide better performance  than other esc’s that are designed for motors with lower pole counts.

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.
