sig hog bipe CG problems
Hi i have a newly completed Sig Hog Bipe with a brand new os .91fs (non Pumped) running. I have been running the engine very rich to start out with. I tested every thing before i had some one with a hog bipe at my club fly it. The CG was exactly were it was supposed to be, 3 1/4 inches back from the leading edge. The plane taxied fine and seemed to take off fine as well. Every thing after that was not though. The plane was flying extremely tail heavy causing the plane to snap and stall very easily. THe guy test flying told me it was flying very tail heavy and needed more weight in the nose but the manual says 3 1/4 from the top wing leading edge. Has any one had this problem. Where should the CG be? I can't believe that the lowest setting in the manual would be that tail heavy! It even suggests to go further back to over 4 inches for more advanced aerobatic flight. Any insight would be great thanks
