I ordered the 3500 psi cylinder from Matheson Tri-Gas.  Our local location didn't have it so they had to get it from Houston.  It's about the same size as a 200 CF, just way heavier and it uses a CGA-680 fitting instead of the CGA-580.

Robert,

Great work! I can't wait to see this fly.

Question: How do you source 3500 psi helium? What size cylinder is that?
The 300 CF bottles I order are around 2400-2500 psi.

I ran a vertical static test of my flight vehicle this weekend using my
250 lbf LOX/kerosene engine.

I'll post videos later but it was a 12 second run.  Everything generally
worked but I ran into some annoying test setup issues.
