Patrick Peebles, the inventor of the FanWing, kindly gave me experimental data with which I could compare my simulation results.
The following are the results of running on one, rather coarse, grid under two wind tunnel speeds and comparison with experimental data provided by Patrick Peebles. I may post a grid convergence study later, but with a few tests that I unfortunately did not record I saw that there was little difference in doubling the number of cells near the rotor. The grid used also did not have typical boundary layer cells near the blades.

As you can see, the results are quite good for a first-order or qualitative evaluation, especially for such a coarse grid.
