Yeah, not worth my time. I was working on a manifold idea for the
Bloodhound motor at one time for a full pressure test. HTP hybrid wont
have the same issue. Adding a bit of AP to the HTPB (5%) was also an
interesting solution for that motor.
Yeah, I just can't get into the hybrids. Not my thing unless they are
pressurized versions.
