During which times the engines of most airplanes just sputter.
Aerobatic airplanes usually have at least one tank with the fuel
pickup on a flexible hose that follows the fuel. That's usually called
a "flop tube."

Do any of the experimental aircraft designs use just a simple hose with a
weight that follows the fuel. It's very successful in modeling. You just
stick a weighted fitting on the end of the hose called a "clunk".
