I made this 12 blade fan to replace the stock five blade fan that came with the Starmax F-5. It produces 830 g of thrust @ 630 W with the stock Starmax F-5 motor and 4S battery. Warning: If you run this or any other EDF fan outside a plane, make sure you wear protective goggles and keep fingers away from the intake. Balance the fan by screwing in M3 grub screws into the holes around the hub of the fan by trial and error. Hold the duct in your hand and spin up slowly to feel for balance after you insert screws in different holes.
