I've skyped you about it. I'm interested in a custom engine for a SHF, contact if it's doable. Performance unchanged for balance reasons, of course, but with purple - white particle spray on cruise charge with distinctly nomad-esque nozzle effects.
Think a magnetoplasma engine - VASMIR style, InRp using a magnetic bottle to channel exit gasses in the Kilo Kelvin temperature range.
