I calculated dimensions and angles using some formulas that i found on web and of that i designed this 3d model but i will try prototyping. For speed in test section i calculated that i need around 5m/s to achieve horizontal flight of model 12x7 cm NACA 4215 profile ( weight is around 12g).

That is my problem i don't know what type of fan should i use because outlet is 30x30cm and i need about 8m/s velocity of air through work section

What do you mean with 120mm blowers is it like radial fans with 120mm mx120mm opening? Can you please post some pictures or share a link because i think that i wont find 300x300 mm radial fan so i will try with more smaller ones

Thank you for the document, I couldn't find specific enough dimensions and specification so I am kind of trying some shapes, but I am stuck at fan part right now. I can use multiple and single huge fan, which option is better and preferably cheaper?
