If you're not uptight about looks, put a tank on the inboard side.  You'll have lots of room, and centrifugal feed to the engine.

I've never tried it -- I'm uptight about looks.

I might be out of date but Brodak had/has a line of nice looking tanks.  Find something there around 3-3 1/2 ounces.  Profile tanks tend to be taller vertically to cram more capacity into a smaller space.  Look at their website. I've seen the tanks in the old Muncie Hobby Shop so I know they exist.

I recommend the RSM "Snub Nosed Uniflow" style tanks. They are designed for short nosed planes like Ringmasters and Flight Streaks and can be purchased directly from the web site "rsmdistribution(dot)com. 8)

Jason, my Ringmaster uses the Brodak uniflow profile tank—the one with the vent and fuel pickup tubes coming out the top. The only down side is the fuel pickup on the top which puts the needle underneath. That's fine for providing some protection in the event of a controlled flight into terrain but it makes the needle a little difficult to adjust—especially with the needle position of the Fox.

I use OK Model 80cc tank because my S-1 is powered by OS FP20. Fox will need 3.5-4oz tank.
It seems that somehow it may be possible to use Sullivan Slant 4oz tank (see pic).
The FP20 is installed on rear end of the engine mount.

Why don't you make one that fits into the space you have available?

That way you can control the amount of fuel you carry and the configuration of the tank - whether you want atmo or uniflow.
