Hi Jay,
I`m living in sunny Spain / Eu.
i bought N11YY In March this year and as ever, there are so many small troubles to remake, but fortunately she is over all in good shape, an it is not essential.
I have momentary portable oxygen in the plane. It does his duty. But I want the installed system may work as it should.
I`ll put myself on contact with Pecise Fligt.
many thanks
KJB
