Interesting, it looks like it got major revisions through the series. The first one I found ("I know I remember an Orca Gunship from somewhere" phase) has sort-of stub wings, fixed fans in the wings (takeoff assist?), and what I think are pivotable jets (TW vintage). Older TD style, as you say, is pretty much a heli form factor aside from the turbofans. One of the developers is Lancaster Lifting Body, which might imply that the hull is an airfoil, which could push it back towards plane.

I assume this has been discussed several times by now in the community!
