allows you to interact with all your printers via the Cloud, and many other exciting new features.
I designed the blade starting from an NACA6409 and then scaled the hub, mid and tip plane parameters to reduce in Chord & Thickness with radial height. I've attached a chart with the lift drag curves for the aerofoil. I choose the NACA6409 due to the very steep lift profile so I could tune the AoA to max and then very quickly reduce lift either side of the design point (20 degrees) and therefore minimising the amount of movements the PvP had to make to stall the aerofoil at high speeds.
