Hi

I'm having some problems with my weight and balance calculations. By my calculation I can never get a situation where I can be within CG limits but below MAUW with a passenger heavier than 100lbs or so regardless of fuel quantity. I do have a full spreadsheet that calculates CG and weight for different scenarios and then combines them to give an overall CG/weight matrix but for now I thought I'd check the basics.

Here are the weights as given to me when I bought my 'Duster:

Do these weights and arms look reasonable? I am 200lbs 'ready to fly' - maybe I should give in to my 'better half' and lose 20 lbs!
