Hi all,

I need 3 blade or 5 blade fan spare for 74 mm EDF for brushless 3800 KV for my EDF of which I have damaged the fan blades.   If anyone is having a burnt out 74mm EDF with fans intact I am ready to buy it at a price.

The 74 mm EDF is from hongkong, has the brushless without any shaft, housed inside the fan impeller/ spinner and the fan blades around it. Looks some what like the photos posted along

Still Wanted anyone ????. :)

I have rewound the motor and I am using a CPU fan clipped, modified and mounted for the fan. Some how not happy with as not as good as the original due to unbalance of the blades, seven blades of the CPU fan in place of the three, further the winding is of the brushless now is thicker than the original therefore the amperage is much higher. Though it is giving good thrust, it is close to 40 at full throttle. and the thrust is not commensurate to the wattage.

I am going to attempt again with thinner windings and fan with lesser number of blades and more balanced this time if I do not get the original blade.
