the Jetbanger is one of the most under utilized machines at high altitude & DA, probably no one was game to push them where we do?
oh & she (JetBox) is the safest Rotory machine ever built, bar none
Sure the B & BA is a bigger machine than the Jettie hence the higher carrying capacity, but as the DA & altitude goes up, they fall away very quickly, only to match the JetBox in performance at ceiling but at a much higher operating price
Cheers & always land back happy
