The JP Hobby 90mm 12 Blade 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.

1057KV  motor produces 5.1kgs of thrust with  12 cell LiPo and the Amp is 96A.

The highly rigid structure is capable of running up to 75.600RPM to produce extremely high efflux velocity for maximum speed and efficiency.

The aluminium shroud body acts like a heat sink and new cooling structure at the motor mount assuring the motor will run cooler. The EDF also has a unique "Anti Blade Fly out" system which ensures the rotor remains safely within the shroud if the fan happens to come loose.

The fan and motor weighs only 455g giving a high power to weight ratio.

You could assemble our EDF system with any other motor without losing dynamic balance effect.
