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

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

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

CAUTION: JP Hobby EDF are fitted with specific 12-pole motors compatible with JP Hobby brushless controllers offered as "Must have Accessories" on this page. Only the use of these controllers validates your warranty and ensures the correct functioning of the EDF.

JP Hobby EDF are only guaranteed if used with these ECS.

Description

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.

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

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

About the above measures : they have been read on the test bench with the intake lip on the unit. The measures have been made using a bench stabilized power source. Results may changed depening upon your equipment and situation.

The controller should be chosen 20% over rated due to the long lasting load.

LV = low voltage controller up to 6s, HV = high voltage controller above 6s.

Battery should be chosen about 15/ - 1/20 of the max current for 4-3 minutes WOT. 30-40 C is appropriate.

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.
