If the old prop was a miserable 85% (it should be in the 87 to 91 range) then the new prop would be up around 102% or so in efficiency. Since no prop ever gets efficiencies anywhere near 100%, there has to be something else going on with the data. Still, it sure looks like it made a nice improvement! I'm looking forward to flying it. Regards, George >>> I just installed a Hartzell Scimitar prop on my IVP and have the following data comparing it to the original 3 blade Hartzell. Still testing but the initial results look very good and I thought I would share them with you: <<<
