Thanks. I just like the elegance of the design of non-tiltrotor VTOLs, in the sense that there aren't a lot of extra parts, just two motors and two control surfaces. The downside with most designs is the stability of hovering in a cross-wind. You kind of need to automatically yaw so that the wing is span-wise towards the wind. Otherwise it is difficult to maintain position.
