I have gone so far as to get a quote on this jet from Gotz Vogelsang. When funds permit I may go for it as I absolutely love the plane and I would like to fly a delta. I would love to know if Airworld improved on the Liebtrau kit, molds are one thing it could be quite different internally.
Looking forward to following your build and seeing how it all goes together. With that nice new shop you have no excuse to keep us all waiting, Ha!
