Club Homepage Forums Classified Ads Buy & Sell - Everything But Airplanes Sensenich 69CK Propeller

I am about to buy one. Does anyone know which vendor has the best price? List is $4,350.00, Wag Aero is asking $3,899.00 online.

When I bought mine I happened to find it in stock at Tiffin Aire in Ohio. I seem to recall the price was a bit less than through Aircraft Spruce.

I wasn't shopping for best price, I was just trying to get it faster than the 30+ days I was being quoted by other places. However, it seemed to work out.

I just Googled the prop part number and found it that way, as many prop shops seem to advertise what they have in stock on their web-sites. Alternatively, you can just call any prop shops and see if they happen to have one and/or can get it faster/cheaper than Wag-Aero.

One extra tip - since I bought my prop from a prop shop and not direct for the manufacturer through an on-line store, I had the option of having it repainted to my liking. So I had them paint it white with red tips. In my opinion, it came out really nice compared to the stock grey with white tips. Even Tiffin Aire said they had customers notice it and ask if it was a composite prop.


Of course, with the extra painting the price went up a bit, but it was worth it to me. Here's my post on the subject (from ten years ago):

PS - as I re-read the above link I'm reminded that the first spinner didn't fit correctly (the holes were mis-drilled). The spinner is made for Sensenich by ACS, and the complete package isn't always test fit for accuracy. Something to ask before buying if possible.

What do you have on it now Fred?

I have a 1A100/MCM6950. It was pitched 48" when I bought the plane, but it was VERY short, so I had Maxwell re-pitch it to 50". The RPM is better now, but I suspect it performs about like a new 48", and is probably not very efficient, as it has been whittled down over the years, including rounded tips. I figure a new "L" series 69CK will be much more efficient.

Perchance did you notice any increase in cruise at the same RPM with the re-pitch?

The current prop on JBN is short too - though it sounds like yours is shorter. We do have a lightly used, freshly overhauled one to put on this spring, I'm hoping the extra 2" in length adds at least noticeable performance gains but also wonder if a re-pitch on the existing one would be beneficial.

I show around 2550 rpm during the initial climb @ 65 mph IAS (digital tach). Before the re-pitch it was more like 2630. In cruise I don't see the kind of speed that many others on this forum report, even with the 50" pitch, again because I think my prop is not very efficient.

I hope you guys post the performance results of the prop changes. For instance... Max static RPM, Climb RPM and Cruise Speed at (X) RPM... before and after.

I spent lots of time investigating propellers and performance before and after reworking Delmar's HCM. It would be neat to install and New Propeller on do same day performance checks.

I'll get some decent numbers on mine before changing it and compare.

Simply replacing our worn/whittled McCauley with another used, but fully dimensional, McCauley made a noticeable difference on our airplane. So, an apples to oranges comparison of replacing an old whittled McCauley with a brand new Sensenich doesn't really provide any real useful data when simply comparing MCCauley to Sensenich. It would be much more useful to compare a brand new McCauley to a brand new Sensenich.

If I were a betting man, I would wager that there wouldn't be much, if any, significant difference.................

Too late - I already ordered a new 69CK.
