If you're looking for high performance and that realistic jet sound in your latest 64mm sized EDF model, then look no further than this high quality 12 bladed unit.
The 12 blade fan moves a greater volume of air to make for a quiet unit with an amazing sound, this is the closest you will ever get to the sound of a turbine without actually buying one!
Molded from 30% FRP with integral mounting lugs, the unit is for use with 20mm EDF motors or those with a 20mm extension and has adapters to suit 3.17 and 4mm motor shafts.
For the best results from this and any ducted fan unit we strongly recommend checking the balance of the complete assembly and eliminating any sources of vibration.

Always use a Watt meter to ensure that your motor and ESC are running within specs, as 10/12 blade fans draw more current than conventional types.
I know it says so at the bottom of the product page, but it's worth reiterating...check your amp/watt draw with this fan!!! It is power hungry! Mine drew 54.32 amps on a 4s pack, for 761 watts, with a 3500 kv freewing EDF motor. It's an animal. It sounds really fantastic, far better than the 6 blade unit I replaced. Unfortunately thrust seems very similar to the 6 blade unit (judged by flying the plane, I didn't measure thrust), but draws far more power. On my freewing 64mm F15, It has unlimited vertical. These fans with a lot of blades aren't very efficient, but they sound really nice. If you have a motor and ESC that will handle 800 watts in a 64mm package, this fan is a great option. Just realize it will cost you flight time compared to a fan with fewer blades.
