fuel calculations aren't this hard.

UT at 5,000 and you "trim" for best glide you have roughly 10 minutes. gliders are built different so they can last up there. not too sure about their aerodynamics. so if there is anyone here on the cellar that would care to elaborate...go for it.

mari i got on his ass a little more than a week ago about not trusting the guages. i asked him how much fuel he had and he told me what the guages said when i was expecting a time endurance. yeah, they give you an idea of how much you have but NEVER, EVER, trust cessna fuel guages. you do what you did in your old car. you have X gallons, you burn Y gallons an hour. plug it in, do the math and you know your endurance.
