Leif, yes I have seen the work of Griff, and it is very good, but it seems that rotary engines (because of their major symmetry?), Sopwith Camels and Fokkers are so much more popular with 3D artists and illustrators. I have filled in the feedback questionniare on Griff's site and mentioned my interest in the SE5a.
I have purchased the Orlik SE5a model, together with it's full set of laser-cut frames (to build the model with some of it's internal contsruction exposed for viewing). It is very detailed, and probably the best SE5a model available - who knows when I will get around to that, lol!
