RE: I've got some GREAT ideas that I could send out...
I've been working on a 1/10th scale Ju-52. Built from enlarged Graupner electric plans and beefed up for glow engines. 120" wingspan, approx. 30 lb for 3 Saito 91's.
I did the corrugation with plastic strips glued in place. I don't recommend doing it that way unless you are very patient. Took a long time but looks realistic to me.
Just need to finish the canopy and then paint.
