Ducted Fans

This large fan is extremely powerful and produces around 140N of thrust on a 12s Lipo battery. It is fully 3D printed and uses two high-power electric skateboard motors for a power of around 7kw.

120mm EDF

This lightweight thruster is extremely powerful and intended for flight applications. Producing 42N of thrust and weighing less than a kilogram including batteries, this thruster has the thrust to weight to be used in R/C planes, drones and small thrust vehicles.

300mm EDF

This large thruster is powerful and light for its size, making it the go-to for small thrust vehicles with more than 80N of thrust. This particular design was specifically made for a jet scooter and both single engine and dual engine variants were able to get me going pretty fast.

Rim-driven EDF

This unusual motor setup for a thruster was an experiment in getting even more power out of a given blade diameter by packing the motor itself into the rim of the blades and the surrounding shroud. This proof of concept was able to work, but it had difficulty starting and the printed coil holders were enough outside the airflow to have overheating issues.

Green Lightning 400mm EDF

This massive thruster was built to be the primary power system of the thrust go-kart Green Lightning. With printed blades and stators and a Kevlar composite lined bucket for a duct, this huge fan produces nearly 220N. It used individually printed blades interlocked to a laser cut hub and the largest drone motor I could get a hold of.
