Back in 1969, my uncle flew a scratchbuilt P-39 or P-63 from what he said were MAN plans. The model was covered in a beautiful then-new product called Monokote. Is my memory fading, 'cuz I can't find the plans on the MAN website. It was a semi-scale stunter, and no, not the Sterling kit. Any help would be appreciated as I intend to build one for his B-day
