Metal JP 70mm Ducted Fan EDF Jet 12 Blades 4s-6s Lipo Motor Electric for RC airplane Model Accessories Parts 3055 2250KV

Features:

100% CNC aluminium JP Hobby EDF unit (shroud and rotor) for 4, 5 or 6s  (7s lipo possibility).

The V2 version offers an exceptional reduced gap of 0.25mm 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.

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

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