Good info. I will remove Trailblazer from my
lexicon of descriptive terms. One can back into the
“ approved” polar of inertia values by looking at propellers approved for the IO-470 series, ranging from
fixed pitch 2 blade to constant speed 3 blade.
My experimental propeller 3 blade composite fits nicely
within the envelope. The 2 blade composite is at the low end of the spectrum.
I looked at the two blade and could not get the inertia up enough by taping $$ on to the blade, so I just went with 3 blades, seemed simple and reliable.
