The EDF that powers my EL-39 3D printed jet: https://youtu.be/9tShEHO5M5s
https://cults3d.com/en/3d-model/various/el-39-semi-scale-rc-jet-for-120-mm-edf
I recommend a 120 A ESC and 12S lipos. Expect 85-100 A current draw. I haven't measured max thrust as my thrust stand maxes out at 5 kgf.
the photos show the fan with rubber inlet and exhaust installed. It will be shorter without them.
------
Safety warnings:
-This is a very highly loaded assembly at high speed so it's important that you know what you are doing.
-Make sure the integrity of the printed impeller is good before trying to run it.
-Always wear protective glasses when test runnin the fan. Always protect your eyes.
-Do NOT run the fan at high power while holding in your hand.
-Keep your hands and any loose items away from the fan when running. It WILL shred your fingers if they get sucked in, and the suction force is very strong. If something gets sucked in it can damage the impeller and potentially shatter,
