Am I correct in thinking that is a pusher prop?
Yep, driven by a Pratt and Whitney PT6A-42.
pusher prop design
Yep. As far as I know it was under construction but never flew. His last design that did fly was the XP-99.
Don't know what the silhouette is, but it looks like there was a Spitfire helicopter over the page. Any pointds for that
Ha! I should hand control over to you for that.
Damned if I could get rid of that artefact no matter what I tried, hence the 'darkness' as a final resort. But yes, it is a
Spitfire Mk II.
