Question
EDF 8 blades vs 12 blades

Hello guys, I have been flying EDF`s for a time but always have been flying with stock components. Recently I have an incident with my VIPER 70mm 8 blades EDF fan unit and when trying to replace the fan I could only found an 70mm 12 blade EDF fan so I purchased and installed.

What is the difference bewteen 8 blades and 12 blades, I think this works the same way as when you change props size and pitches on a plane but would lie to know the experience of you guys that are operators.

for sure the sound is different and I feel an extra power. (haven't flown yet)

I will appreciate your support.

regards.

Jose

Much higher load. Besure your motor, ESC and batteries are up to the task. Usually the high count fans require a lower Kv and longer(more mass) motor.

Hook up a watt meter to see what it is drawing. Best tool you can have flying EDF.
