That's a lot bigger than the 5/8" tube I was thinking about when I started going down this mental journey. Let's see... pi are square...14 times 12 is 168... gives 296.73 cubic inches.. quick conversion with help of the internet says that is a little over one and a quarter gallons. At 8lbs per gallon, that'll add over 10lbs to the airplane. Hmmm, what a conundrum. The thing is, the open area that I was considering would allow me to pull intake air from the wheel well, eliminating an additional opening in the skin for the air inlet. The outlet would be at the 70% chord point of the turtleback, and I'd have a long run to make a perfectly flaired inlet and outlet. But do I want to add 10lbs? Does a long tube work well for a reservoir? -- http://www.ernest.isa-geek.org/ "Ignorance is mankinds normal state, alleviated by information and experience." Veeduber
