I seriously doubt you're that much off.. Did you use these: Main wheel right: 94.06" aft of Datum Main wheel left: 94.06" aft of Datum Nose Wheel: 34.55" aft of Datum What was the weight distribution? Can you post the numbers? I also assume the plane was weighted longerons leveled w/ closed canopy etc etc.. Maybe this spreadsheet would help: http://www.rv8a.com/downloads/RV-W &B.xls PS.. Just for fun, I used my numbers for weight on each wheel, using the above arms and I got 78.76" empty C.G at 1081 lbs.. which is more in-line with what'd be expected.. Good luck..
