120 mm EDF

This is the fan that powers my EL-39 and He-162. The He-162 impeller is higher pitch and gives more thrust and higher current draw.

They are designed for Het 800-73-590kv motors and 12S batteries. Current draw is ~95 A for the EL-39 fan and ~110 A for the He-162 fan.

Take extreme care when running any EDF, sespecially a homemade one. An exploding fan can cause severe physical injury. This is only for advanced modelers who understand the hazards.

-Motor is a HET 800-73-590kv with a jetfan heatsink:

The impeller is mounted to the shaft with two long grub screws. However, one of the screws MUST sit in a 3 mm hole drilled perpendicular to the motos shaft, about halfway through the shaft. This is to ensure the impeller can not leave the motor in any situation as the hub
