Hi, I am a fresh first time Skybolt owner and my plane is in good shape (1977, IO540, Constant Speed Prop), however I am missing some important documentation, especially on weight & balance (as well as a handbook).I found some handy documentation on how to calculate and measure CG & Weight and Balance (FAA-H-8083-1A). I guess I have to recalculate the CG and arms. I found an A&P mechanic who can probably help me out on that, but I have no idea what the limits of CG for my plane are. Is that specific to mine or is there some data available which is valid for all Skybolts ?I appreciate your help and experience!
