Question How long before you need a stuffer tube?

I'm sure that I won't need a stuffer tube for any of my recent builds, as I've got plans from multiple Mean Machines that used D, and later E engines that didn't have a stuffer tube. That said, sitting before me is the plans for the Citation Patriot, and it has one (but it was using 18mm engines)

Out of curiosity, how long can a rocket (using BT-60s for the body) get before it should get one?

Thanks!
Jim

Very long. Today's ejections are pretty potent. Use a baffle in the upper most coupler to keep the recovery system near the nose. You can go super long by having the rocket separate at the mid point instead of the nose cone. That way a 10 ft rocket only has to be pressurized the first 5 ft.

If you have an old style nose cone ejecting Mean Machine, glue an 18mm motor in a 24mm casing and do a ground test. You'll be surprised how much of a kick it has.
