Green Lightning 400mm EDF

This gigantic ducted fan was designed for and used in a go-kart called "Green Lightning" but it has an array of other applications including other vehicles or R/C aircraft. As a completely custom design, this huge fan has 12 interchangeable blades and room for a powerful motor. The motor and blade mounting plates ideally should be CNC or laser cut out of metal or carbon fiber due to 3D-printable plastics not handling well with heat. This project uses A LOT of filament (>1.8kg) so beware that more than one 1kg roll will be used up.

Performance:
I use a 7Kw 130kv brushless motor on a 12s lipo battery to power this thruster, but more powerful motors may yield better thrust. The theoretical thrust of this unit (https://rcplanes.online/calc_thrust.htm) at 4Kw is in the range of 150N -190N with a large margin of error from simplifying the blade geometry. For more power, a lower Kv motor can be used at a higher voltage. Motor may become warm, so a cooling fan in the tailcone is strongly
