I am building a Pitts S-1-11B. Does anyone out there have the CG limits and datum reference for those limits? I cannot find this information on the plans sheets anywhere. I called Aviat, and they are no help at all. I have contacted several notable S-1-11B pilots, and they all said they would help me and no one has. Frustrating to say the least. If anyone out there has this information, I would GREATLY appreciate receiving it. Thanks!!!
