Naive question about fuel tanks
So there are no wing tanks? Probably to keep with the wing removal ease?

Correct. The plumbing is much simpler if the tank is in the fuselage.

BUT: I have given thought to putting a long PVC pipe tank in each wing, stuck up thru the large lightening holes. Reckon one could get another hour of cruise that way? Just what IS the diameter of those holes anyway?

Add some fuel.
Why not just add one of these! Plus its removable!

I don't know if that is a good idea or not but I do know that when this is done, builder put baffling in them otherwise when they are half full they slosh back and forth when banking. That is a long way to slosh and the weight and momentum can make you over roll. That's what they say anyway.

Wing tanks full of fuel will also impose extra inertia loads on the wing structure, which will reduce the safety margin and possibly overstress some of the parts that you may be relying on to stay airborne.

Those marine tanks leak in negative gs, at least the two in my sailboat do. Since I remove them to take them to a gas station, and the gas sloshes around, it's a bit awkward. This happens even with the vents closed.
I see that yours are rigged to vent overboard, a very good thing.
Other than that, it's a neat solution. Removable, portable, inexpensive.

Where indeed!
The Theory and the basic concept is easy, its finding the hardware locally to make it all come together, that's hard.
I suggest you visit your local Aviation Bass Pro shop or Aero Cabelas. They have some great stuff for Airplanes.

If you keep the ball centered, the tanks don't know (or care) if they are banked or not...
