I'm the owner of G-CGNZ, another Jab6 installation. I also use the
Sensenich 2 blade.

Some of you might remember I said I only knew of one successful Jab6
installation? Well I had an interesting conversation with
a guy who's been happy with his for a few years now. Sensenich 2 blade prop,
3 blades are not ideal on a Jab6 because of
crank resonance issues which I hadn't heard about. There isn't much useful
info about Jabs although must admit I don't look far.
I wonder what the Mach no of the prop tips at 150 knots and 3300 rpm? Must
be going super critical, around .65 ish?
With a wooden prop the blades need to be thicker and that isn't good for
high speed. Are Sensenich using super critical sections?
