Re: [Flightgear-devel] c172j

Syd,

I had to fix fuel usage for the Goose to drop fuel usage to about 65%
of YASim's guestimate. I generally replace the default nasal fuel
system with my own version these days, and as part of that, at least
in the Goose, I included a fuel-scalar that reduced the fuel-consumed
amount. Unfortunately this is in my later Goose build-- the one on my
site hasn't been updated in forever. If interested, I could send you
my work-- you'll readily see what I did as it's pretty easy.
Unfortunately a windstorm just blew part of my roof off, so I might be
busy with other things for a while.
