I could use a little help regarding a fuel tank.

[Andrew Borgogna]

I am currently building a Lil' Zilch for VSC-20 to fly in ignition.  I have a brand new in the box Foster .29 replica engine and want to fly it on glow fuel.  This seemed to be the way to go based on what I saw at this years VSC, nobody seemed to be using gasoline.  Which I might add is all I ever used when flying ignition in Old Time Free Flight. 

The tank compartment does not seem to lend itself to any off the shelf gas tanks so it looks like I will have to make one myself.  What I need to know is in terms of volume what does one ounce of fuel equate to.  I want to build a 3 to 3.5 tank and I need to know what the volume of such a tank would  be.  Does anybody out there know the solution to "1oz.glow fuel = x ci of tank volume"?
Thanks in Advance

Andrew,

To figure capacity in fluid ounces: Find the volume in cubic inches (Length x Width x Height) and divide by 1.8.

Thanks Tom, that's what I was looking for.

Andy,

If you have a front intake Forster remember that the mounts are not on the center line. Not sure, but I think the rear intake ones were that way also.
