Sensenich FP.

[Python]

Hi, I’m thinking about changing my FP Sensenich metal prop to a Sensenich composite ground adjustable for my 160hp RV 6. Has anyone done this before & are these suitable ? Are 3 blade or 2 blade preferable ? Apart from the obvious advantages of changing pitch & less weight are they smoother ( less vibration) than the metal prop ? Also will they handle rain ? Cheers .

Original wood propeller, was changed to a metal Sensenich, and now to GA Sensenich on my O-320 RV6. Yes, the Sensenich GA are suitable for the RV6, recognizing the lighter weight of the GA will change the weight and balance. There does not appear to be a performance preference between the 2 and 3 blade propellers. My Sensenich GA is not any smoother than the metal propeller. Both dynamically balanced to very low vibration. I have not flown the GA in rain so no experience.

On my 9a with stock 160HP -320 I just changed from a metal Sensenich 2B to a 2B Catto composite. The Catto prop is lighter, smoother, and resulted in 5mph faster cruise and no RPM limitation. I also saw my CHT on climb out lower by 50 degrees and my rate of climb go up by over 200 fpm. This spring, I will increase pitch a bit more and really go fast! Now in std loading, level cruise flight, my elevator runs flush with the H-Stabilizer due to change in cg further aft.

Same path for my RV-6. Now I've got the 2 blade composite GA propeller on it, and have put several hundred hours on it. I've flown in it rain a number of times and haven't noticed any issues, erosion, or other signs of wear. It's a good prop.

I just did this. Swapped a two-blade aluminum Sensenich 72FM8SS9-1-85 for a three-blade, composite ground-adjustable Sensenich 3F0M8-C68NFF. This is on an 8A with an IO-360. I haven’t flown the new prop yet, but the condition inspection should be completed this week, so hopefully I’ll fly it soon.

I have a Sensenich 2 blade GA (I need to sell) that I flew for a year. I converted to CS at engine overhaul. I did fly through light rain with no effect on the prop. I don't know about vibration compared to metal but the GA Sensenich is very smooth and because its light engine acceleration is very fast. Cruise speed is the same with the GA compared to the CS.

hello, I wish I saw your post earlier.. as I just purchased a 3 blade GA... I'm still waiting on it.
Question... What airplane did you install it,.. did you go from a metal fixed pitch to a composite GA? how much lighter was it with the spinner?... Did you need to add ballast in the front or what did you do and what did you feel? I would appreciate the info and experience you had

I have an RV8A with an IO-360. I removed a Sensenich 72FM8SS9-1-85 at 25 lb and put on a Sensenich 3F0M8-C68NFF at 16 lb. I only have 1.5 hours on it so far, so not much experience yet.
