Did static test comparison several hours apart today. Temp about 75 degrees (no fires nice weather, just hurricanes huh Rusty??), turned the Perf prop 5160 rpm. Ed and Tracy reported 5200 hundred with this prop. Did you ever spin the Tracy prop Rusty on your -3? Had previous to rework been spiinning the Sensenich about 4150 rpm, today spun it only 4380. Yuk, they thought they would get me up to 5000. Decided to accelerate the Sen down the runway and if felt good to fly with it. Schocking, it climbed 400 fpm better at 90 knots than the Perf. During WOT run it turned 5600 and 150 Kias. The thermals were booming when I did the test with the Perf and it only did 145Kias, but the turbulence can certainly effect the speed run, so not exactly a fair comparison. The airplane seemed much smoother with the Perf subjectively. Ed had his prop balanced on the airplane. It may be that it was compensating for the engine some and actually made it worse on my plane. After talking to Don at Sensenich, we decided to fly with it a while before doing anything rash. I want to clean up the exit area some also to see if it will turn up a little more without the excess drag area there. Ed, your prop fits in the 9. If you think you might wish to take it back from Lakeland , I will see if it fits in Gabe's 6 tip up. If you prefer, I can ship it back or wait until I'm driving to NC and bring it then , your choice. Bernie, no mud, no dust, no carpet coming loose, just a beautiful day! ----__JNP_000_3821.1ce0.1886 Content-Type: text/html; charset=us-ascii Content-Transfer-Encoding: quoted-printable Dodge vs Ford
