Awesome!
Great stuff Brantel! Congrats on the successful upgrade and great write-up! Where were you 3 years ago when I was trying to figure out how to convert mine (before it first flew)?
The blended airfoil is gorgeous!

Glad it all worked Brian. I had the governor set at 2680 because some prop guru in a land far far away told me that it was fastest just a tad below redline.. May be old wives tale..
Glad you got it all done.

Brian,
I'm guessing the speed comment was tongue in check, but I would be very interested in hearing the speed difference between the Hartzell and Sensenich. Your pitch was 85, correct?
Thanks,
Scott

Yes and yes. I hope to get some speed runs this week.
With the FP, 174-176kts TAS was about all I could get @ 8000ft WOT 2700 RPM.

Congratulations Brian - don't let your face crack from the "even bigger" RV grin !
BTW, back on your comment, "I got the impression that the FSDO and the DAR thought I was a moron for following the rules" - I had a similar experience with the State Board of Aironautics when filing papers for my runway. They asked why I had not sent th papers in earlier and I explained that their forms clearly say that I needed my FAA evaluation *before* submitting to the state. Their replay was, "Oh. Yeah. No one pays attention to that."
Anyway, now I'm wishing I had a Blue Knob!

Just a suggestion. Where the safety wire crosses the flanges on the prop hub, over time the wire can eventually cut into the flange due to vibration. If this happens, the prop hub is "throw away".
Many people sleeve the safety wire with nylon-flow, or some similar, tubing.
As far as notifying the FSDO; changing from F/P to C/S or vice versa, a new 8130-6 is required to update information in Oklahoma City.
If changing F/P to F/P or C/S to C/S, the notification is only to confirm test area.

You mean like this:
On the helicopters I used to maintain, they had this stuff all over the place. We called it spaghetti.
I saw many warnings in the archives to use something similar on this wire so I put it on when I installed the wire.

Thanks for the GREAT writeup Brantel, I've been following along on the edge of my seat. Do you happen to have the same performance chart of takeoff with the FP prop? Would love to see those side by side!
