![]() I imagine I will get better at it as I make more adjustments. It took two of us to set it up with a couple try's to get it in spec. The pitch and tracking set up is a little fiddley at first. So as an initial install this where I stayed. But, there is no pin for 42" and 43" pitch was as close as I could get with the pins. I wanted to start with an apples to apples comparison and set it to 42" like the old prop. ![]() Sensenich installed with a weight delta of -14.15lbs including hardware and prop spinner. McCauley Pawnee prop (P235AFA8442) 35.05lbs removed. Managed two take-offs before wx forced me back to the hangar so I have little to offer as of yet. I just received my prop and have it installed. ![]() FWIW the optical and digital tach on the EM are within 1-2 RPM of each other. I thought I must have had the world strongest 160 narrow deck till I checked the tach out. I have yet to see one that was not 150-250 RPM LOW on the top end so when your mechanical tach says your turning 2500 chances are your closer to 2300. If your running a mechanical tach have it check using an optical or digital tach. I have said it before many times and I will say it again. The difference was enough that after testing the demo prop, I bolted my 82X44 back on for 2 flights then went and plopped my CC down and walked out the door with the new prop and I have never looked back.Īnother benefit of the CF prop is instant spooling and better throttle response when your dragging it in. ![]() I have switch back to BW so I need to run the tests again just to see what the #s are on BW versus skis. 35" and we seem to get about 1-2 seconds longer take off, but a few MPH faster than the 82X44 borer. ![]() At 34 I can turn it up and get the best take off time, but cruise suffered a few MPH. On my 160 HP pacer I was over 48% shorter on take off times (17.7 seconds with 82X44 to 9 seconds at 34") on skis with a solid ice runway and better climb/cruise.įor what its worth, After a lot of testing I turned down one of the higher pitch pins that I can't use to give me a 35" pin and the 150/160 engine seems to like this pitch the best. Every single plane (not just cubs) showed significant improvement on take off, climb and cruise speed. I made up a spread sheet for the local dealer who was involved in the testing and certification flights and we compared A LOT of different planes doing same day testing with the original prop on the planes then the Sensenich GA prop at various settings. ![]()
