...and similar airfoils.
What use are they intended for?
They are essentially symmetrical, but I just ran the polars for the 66-021 and it looks like a symmetrical over a very small range of AoA. Less than +/-4 degrees, depending on Reynolds number.
CL looks good, going beyond 20 degrees (but this is XFLR5!) Tiny drag bucket.
