I have an old curare and agree with almost everything that everyone has said. Leave the tail open, tack, glass, microballoons, but I didn't run the glass cloth past the sides of the fuse. Just flush or there abouts, I think I put a 1 inch strip on, and it has never ever even started to break at the fuse line. It's still holding fine after many years and still flying. Well it's in the hanger, but it still would. The anhedral stab always looked good in the air. Always liked it. Just my opinion on it. Paint it light as possible though. They're real bullets to land. Good luck
