Along with "your blades will fail" "efficiency is pointless" and you posted a CAD model of a fan and told me to use that instead.

I simply said I started the project before I saw any EDF of this size advertised. I don't know when that manufacturer started developing his 395mm, he could have been developing 5 years ago for all I know. All I know is he posted the YouTube video showcasing it in February so before that I did not know that there were any of that size.

Anyway I don't know why you keep saying my project isn't as powerful as a £10k professional carbon EDF. As I said this is like me posting a kit car build and you saying that it isn't as powerful as a Mercedes E-Class.
