You can't replicate flight situations on the ground easily, but a held power setting is very rare!
I still have not worked out why people needed to re invent the wheel (Other than really rare big turbine models which require a completely different approach anyway)
I do think my preferred choice is the best...that's why I use and sell it. If I had any doubt I'd not be risking hours of work and thousands of pounds in flight!

With the right fuel tank installation a container with a tube in the middle will work as there will be no air supplied to the trap, people seem to look at the various huge capacity bubble traps as a Elastoplast for poor tank engineering-its not.

Constantly supplied with fuel this and other traps will work 100% as long as it does not develop air leaks from the multiple joints.
