I am putting together my second showtime, the first has a battery failure. I noticed that the recommended CG is 7 7/16" back from the leading edge at the fuse. I dont remember how I set the first one up. To me it looks like it really should be around 5 1/2" back. I want to set it up for a neutral feel, I fly aerobatics, not 3D. What are you guys setting the CG at?
