EDF Ducted Fan JP Hobby 70mm + 3300Kv 4s Motor

100% CNC aluminium JP Hobby EDF unit (shroud and rotor) for 4s.


  • The V2 version offers an exceptional reduced gap of 0.6mm between each blade edge and the EDF shroud for more efficiency.
  • Jingpin Hobby uses High grade aluminium alloy material for highest rigid structure and lightest weight.
  • The shroud acts as a heat sink, removing heat from the motor. This design creates a more efficiently running motor and will provide peak performance while extending the lifespan of the motor.
  • The highly rigid structure design is capable of running up to 88,000 RPM to produce extremely high efflux velocity for maximum speed and efficiency.
  • Anti Blade flying out design,the Blades be safety kept in the shroud and without damage.It is the best replacement for your plastic or carbon shroud if you want to have a safety 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 bring a better and safer user experience for every RC fan.

The motor and fan unit comes assembled and balanced from the factory.
