Richard, Norbert Habe's database (www.habebert.com) has a little summary data of all the airfoils he has designed, from HN-003 to HN-1091. The HN-216 is not included. It's possible that he did design it and it's just not listed, but it's also possible that some plane manufacturer chose this number to mislead buyers into thinking it's a Habe airfoil.
Anyway, if you go to his site, there's a link that allows you to send him a request for the coordinates and/or polars. If you promise not to use them for commercial purposes, he'll send you the info (for example, I got it for the Espada airfoil when I got my RL). If he supplies polars, you can judge from that; if not, you can use Xfoil to figure out the answer to your question. If he didn't design the HN-216, then there's your answer.

Ok guys, Can anyone tell me anything about the way this airfoil performs? HN-216 In speed ? In duration? In distance? What airfoil would it compare to of the ones we use now? So many airfoils so little time. Thanks, Richard
