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!
