This was flying a year before the one Pred YT video shows, about 10 years ago. The sound track is what I thought of when I saw Preds video. https://youtu.be/iHRyEWpHeec
The Archaeopteryx has been developed over the yeara and now comes in 3 models. The one most suitable for the field would be the electric version I would think. Only 90,000 EURO + freight. Maybe a syndicate buy. Then you could RC it and give joy flights. Sorry I think I got concussion on my last fall off my chair.
