Our field doesn't really have any close neighbors so the sound isn't really an issue. My 20cc I fly 12-15 mins but still have 1/4 tank of I ned to fly longer. Takes me longer to land sometimes if it's windy. I like to have a buffer.
I'll bet it doesn't take @capthis as long to land one of your airplanes. ;-)
