Anyone able to help identify what aerofoil this is? Firstly, apologies for the potato quality of the image below. I am attempting to determine the qualities of a VTOL and cannot find any data online. If anyone knows what aerofoil this could be that would help a bunch! (the green line is the upper edge and the yellow line is the lower edge)
Try contacting the local FAA Flight Standards District Office (FSDO-'fizzdoe') for help. They may be able to tell you how to get a copy of the aircraft's certification documents which may indicate the airfoil used. Mention the aircraft's N-number: N301XZ. To locate the nearest Flight Standards District Office, see here:
