HyperLoop Scale Model What is the best scale factor ?

Tubing ..... obviously smaller diameter tubing is cheaper , and easier to handle.  Tubing comes in standard sizes, so it would be awkward to propose a scale model that did not work with a standard size tubing.  Metal tubing may be cooler but I think plastic ABS ( black ) tubing is so easy to work with.  Gluing , cutting , machining are done with ease.  I am fairly sure that ABS tubing will work successfully all the way to a full vacuum.  The maximum pressure the tubing will have to withstand is 100KPascals ( 14 psi ) .

2 inch diameter tubing is cheap.  The capsules may be too hard to build.
4 inch diameter tubing may allow for easy to build capsules.
