I just received my prop and have it installed. I have minimal testing as of yet. Managed two take-offs before wx forced me back to the hangar so I have little to offer as of yet.
Here's what I can tell you so far:
McCauley Pawnee prop (P235AFA8442) 35.05lbs removed.
Sensenich installed with a weight delta of -14.15lbs including hardware and prop spinner.
I wanted to start with an apples to apples comparison and set it to 42" like the old prop. But, there is no pin for 42" and 43" pitch was as close as I could get with the pins. So as an initial install this where I stayed. The pitch and tracking set up is a little fiddley at first. It took two of us to set it up with a couple try's to get it in spec. I imagine I will get better at it as I make more adjustments. I don't recommend that you use an ultra sensitive digital level. Use a cheap one otherwise you will be chasing numbers.
The engine start was very fast and very quiet. This prop is soooo lite! I ran the 50% RPM requirement for 10 minutes and retorqued. Then did a static test and the tach showed 2500 leaned for best power. I did not use a light tach to check the gauge but I will.
Takeoff and climb seemed a wee bit slower but...I also installed new 31" tires with extended gear and AOSS and added 44lbs to the bird.
Here what was VERY NOTICEABLE(!) the aircraft speed was increased across the board (in the pattern). Of the two trips I made around the patch, of which I have done a thousand times...I had to pull the throttle back ALOT farther and ALOT faster to slow down.
This was VERY noticeable and totally unexpected.
More to come if Winter ever leaves.
