Really off-beat choice, typical WNW I would say! There are some sprue shots on the IPMS Germany site, too, showing some nice details in intricate moulding -such as the Fokker-type control stick with the combat throttles moulded in place, and some very delicate and curious looking framework (looks like a lower spar or something)
I'll wait until I see a few built, I like the curious and offbeat, but not one I'll go out and get immediately.
Somehow I was under the impression these had BMW engines, but I guess being wrong on that gives away my level of knowledge on this machine...!
