No "thoughts" yet?? LOL

Lower blade count fans are more efficient. So you will get more thrust for your Watts.
Not tons, but enough to make a difference in flight times.
But then you don't get the great "CS10" sound..... sort of.

The real source of 'great jet-like sound' is a fan actually being QUIETER. Which then allows you top hear the airflow generated noises far better. The White Noise of the airflow system.
A low blade count fan sounds like a leaf blower and drowns all of that sound out.... but a well balanced and very high RPM lower blade count can at least be 'better'.

So if you want optimal jet-like sound, use the CS10 or CS12 (70mm).
If you want optimal power/flight-time, use a low blade count fan. eg that HET 6904

Personally I won't touch anything under the CS10 !! Because the sound result moves your models to far nearer 'real jets' than 'garden leaf blowers'!!! I do hate the loss it costs, but just have to accept that.
