JP Hobby 105mm 12S All-Metal 12-Blade EDF Fan Unit w/4250-875KV Brushless Motor

This high-quality all-metal fan unit uses the latest technology and high-grade aluminum alloy to ensure a powerful, smooth-running unit. It is built to the highest of standards, and each blade is precision made to generate the best airflow, and to a rigorous 8-hour fatigue test before installation.

The highly rigid structure is capable of running at a very high RPM which produces an extremely high efflux velocity for maximum speed and efficiency. The design includes an anti-disintegrating safety feature that will stop a blade from flying out of the shroud in the unlikely case of failure. The shroud itself acts as a heatsink for the motor and each unit has been dynamically balanced to ensure smooth running and a long lifespan for both the fan unit and the motor.

With a thrust of up to 7.5kg, the JP 105mm all-metal 12-blade EDF fan is the perfect power unit for the HobbyKing Sports Hawk, it is a marriage made in heaven. It will supply an amazing amount of power and thrust very smoothly and with an amazing jet-like sound, to push the Sports Hawk around the sky in a true jet-like style.
