I'd rather see the pitch or chord angle at the standardized 75% diameter instead of the silly A, B, or C. That at least would give some handhold as to what to expect. As a new kid on the block, Vess should know better than to be fuzzy. Data please. like blade angles and prop load factor at stationary, and at pitch speed.
Call me oldfashioned, but the design very much is like the old rubber powered handmades, with narrowed tips for noise reduction.
