Well, its what you get when you
fly that counts {:>).
Bernie, I'm in no hurry for the
prop, just throw it in your van next time you come up this way.

Subject: [FlyRotary] Prop testing
flight report
Did a very simple flight test on the recut sensenich wood prop
compared to Ed A's loaner Performance prop.
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!
