Do any of the experimental aircraft designs use just a simple hose with a
weight that follows the fuel...

Yes. It's called a "flop tube."

Thanks, Bob K.

Duh? I misread your post.

Although you described it as a hose, when you called it a flop "tube", I
pictured a mechanical tube or arm.

In aircraft use, generally it IS a tube, not a hose.

One also needs to perform similar magic with the oil system if
inversion longer than a few seconds is contemplated.

Actually, its surprising how long the engine will keep running after
forgetting to switch to the acro tank. I've made halfway into an
acro routine before being surprised by the sudden silence. ;-)
