The JP Hobby 90mm 10S 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.


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 aluminium alloy material for highest rigid structure and lightest weight. The aluminium 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.


Design Change Notice: JP Hobby has changed the manufacturing design of the 90mm edf unit.  The tail cone that goes over the motor is no longer part of the edf unit.  JP Hobby has eliminated the tail cone to further cool the motor to improve the performance of the edf unit.  The tail cone shown in the pictures are no longer part of the edf unit.

VIDEO NOTE: While the video shows the edf unit operating on 39 and 40 volts, this is only for demonstration purposes and is not intended to run at this voltage in a jet.  Doing so exceeds the motors parameters and can damage the motor.  This is not covered under warranty.


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.
