Thank you Jean for this interesting blade profile link.

It made me feel more confident with my tapered (1/2"/ft.) blades. I was going to use the 0012 profile due to using a swashplate for blade pitch control but this paper showed that the OA-212 can perhaps provide more lift with less rrpm and it is also worth comparing it to the VR-7B (with tab).
