I’ve not flown one of the newer B14s, which I plan to do. I’ve also got an older B8, which will be an interesting comparison flight.

That 1979 Centuri B14 is constant with latter 70s Centuri B14’s that I had.
I kind of suspect the deep core of the ‘real’ Estes and Centuri B14’s was ditched sometime in the latter 70’s (Estes was once again making the Centuri motors), and that they were ALL probably B8’s by then. The label change to ‘B8’ came some years later.
