Some of you might remember I said I only knew of one successful Jab6 instal
lation? Well I had an interesting conversation with-=0Aa guy-who's-be
en happy with his for a few years now. Sensenich 2 blade prop, 3 blades-a
re-not ideal on a Jab6 because of-=0Acrank resonance issues which I had
n't heard about. There isn't much useful info about Jabs although must admi
t I don't look far.=0A=0AI wonder what the Mach no of the prop tips at 150
knots and 3300 rpm? Must be going-super critical, around .65 ish?=0AWith
a wooden prop the blades need to be-thicker-and that isn't good for hig
h speed. Are Sensenich using-super critical-sections?=0AGraham
