How efficient is that control on most hybrids? I understand regression
rate working in favor of the process. I do admit I have not run any
calculations for regression vs oxidizer flow. Is it close enough to make
that much up? If so it might rejuvenate some interest in hybrids for me.
I'll have to look into it I guess I may have overlooked something there.
My thinking was it wasn't enough.
