120 mm EDF

This is the fan that powers my EL-39 and He-162. The He-162 impeller spins at a higher pitch, generating more thrust and drawing a higher current. These fans are designed specifically for Het 800-73-590kv motors and 12S batteries. They draw approximately 95 A of current when running the EL-39 fan and around 110 A with the He-162 fan. When operating any EDF, extreme caution is essential, especially when dealing with a homemade unit. A fan explosion can cause severe physical injuries. This setup is intended for advanced modelers who fully understand the associated hazards. The motor used in this configuration is a HET 800-73-590kv model equipped with a jetfan heatsink. You can find more information about this motor and heatsink on the following websites: https://www.turbines-rc.com/en/50-56mm-brushless-motors/285-typhoon-het-edf-800-73-motor-50mm-590kv.html https://www.turbines-rc.com/en/heat-sink/1075-heat-sink-75mm-for-50mm-motor-and-ejets-jetfan-120-edf.html To ensure the impeller stays securely attached to the shaft, it is crucial that one of the grub screws sits in a 3 mm hole drilled perpendicular to the motor's shaft, roughly halfway through. This setup prevents the impeller from coming loose under any circumstances, as the hub remains plastic. Safety warnings: - Be aware that this assembly is heavily loaded at high speeds and requires expertise. - Verify the integrity of the printed impeller before attempting to run it. - Always wear protective glasses when testing the fan, and ensure your eyes are fully protected. - Never operate the fan at high power while holding it in your hand. - Keep a safe distance from loose items and your hands when running the fan, as its suction force is extremely strong. If anything gets sucked in, it can damage the impeller or shatter, releasing debris.
