Default Inverted Flop tubes

A data point for anyone considering fuel tank flop tubes.

Decided to see how long my engine would run while inverted and on the NON inverted tank.

I have a flop tube in the right tank and a standard pickup in the left. From "experience" I've noticed I can fly for quite some time inverted and on the wrong tank!

Today, I decided to find out just how long! With only 4 gallons in the left tank and the left tank selected, I rolled inverted and started a timer. At 25 seconds I rolled upright and at the 30 second mark the engine stumbled for about 2 to 3 seconds then it smoothly regained power.

Hope this will convince guys to bite the bullet and install that inverted oil system. There is absolutely no need to put in a flop tube unless you intend to fly inverted for more than 20 seconds.
