I know I tried to build a few as a kid in the 60-70's, receiving them as gifts. never did finish a one of them.
saw a B-24 in a military catalog that claimed to have a four foot wingspan. Sounds pretty impressive.
Anyone ever finish one? They kinda look better to me without the skin. I would call one finished without that part, though I do remember the smell of the dope. What amazing toxins us old dinosaurs took in during our early modeling years.....
