Moment divided by mass equals arm, 52820 / 1549 = 34.10. You may also be confusing commas for thousand separators with commas for decimal points. Hope that helps, T67M

I have the following w&b data for the cessna 150 Empty mass 1175 lbs - arm 32,5" --> moment 38,18 Pilot + Passenger 320 lbs - arm 39" --> moment 12,48 Fuel 9 usg = 54 lbs 54 lbs - arm 40" ---> moment 2,16 totals: 1549 lbs moment: 52,82 When I input these data in aircraft properties skydemon says 1548,9 lbs (this is correct) and moment arm is 34,10 not correct. What am I doing wrong? regards
