So, let me make sure I'm understanding this correctly... You've come up with a hypergolic hybrid motor with performance comparable to that of N2O4/Hydrazine?
Are there any long-term stability issues with either the fuel grain or the oxidizer of choice?

That is what wonders me as well - the main problem with existing hybrid motors are the mechanical properties of the fuel, especially the combustion behavior in the chamber.

Using RFNA as oxidizer is already known technology for decades, but of course, the problems that occur using RFNA are known as well. And well, there is already a lot of N2O4 in RFNA, which really ignites almost everything organic.

Did you use RFNA or IRFNA?
