Charlie, that must be a common gotcha because I did exactly the same thing you did on the bottom wing. Don't have a full shop like you but enough and easily fixed it. Took some time that's all. And I had problems with very warped fuse sides on both the bipe and later an Astro Hog. I'll bet I spent three times as long on both than I should have and just chaulked them both up as anomalies sp? Because if not there wouldn't be such glowing reviews of the sig kits like there are. Lost my bipe and have another waiting to be built so I'm anxious to see how that fuse comes out. And as far as the gotchas go, just read three times or at least just understand what you are reading, measure twice and then stop and take a look to be sure you are correct before glueing. Mine went well and flew great. That's why I want another. Charlie, I remember reading about yours while you were building. What engine you put on it and you still flying it?
