My Copperhead V-10 is an iteration of the V-Max Sidewinder, though mine was inverted mount PA 61.
V-Max Sidewinder had an OS 46 VF, wraparound header to a belly mounted pipe with a straight through exit via slightly too small arrowshaft extension, 4 inch leading edge sweep, with a short nose.
The only Werwage influence would be a pipe and the aesthetics, it was still a thick winged, large tailed model ala Big Jim. I used a wing foam set from Windy for mine, he sent me two others that I gave to Dan McEntee and they are still there in his garage. Very thick airfoil.
