Sure, it's a sum of moments either way. But why would you want to change not only the changed weights, but every other distance in the spreadsheet (or worse, your W&B sheet)? Now THAT's some bothersome math, adding whatever your new arm is to all those moment arms, rather than just the moment arm of the engine alone. That sounds like an increased opportunity for error, at least it would be for me. I know Larry knows this...just pointing it out... Mark Langford ML at N56ML.com http://www.n56ml.com
