I ran a Sensenich GA carbon fiber prop on my STOL 750/Jab 3300.  I had a prop strike and am upgrading to a Gen 4 3300.  I called Sensenich and they told me that my prop was not repairable since it had been discontinued and they now recommended a new prop - the 2E0U5.  Don Rowell, the manager at Sensenich, said it was "an improved design" and recommended it be trimmed to 66" for the 3300.  Fortunately, insurance was OK with this and fully covered the $3K cost!  My previous prop's pitch was infinitely adjustable but required very careful adjustments to get the pitch the same on both blades.  The new prop uses a new system where a pin gauge is inserted into the hub and the blade rotated until it touches and then the blade is locked-down and the pitch is set.  Using the same pin for the other blade ensures identical pitch. An assortment of numbered pins are provided with the prop so the pitch can be varied.

Anyone flying this prop on their 3300?  If you have this on a STOL 750, what # pin did you wind up using to set your pitch and what static rpm did you obtain?

Thanks,

John

Hello John,

I also started out with a Sensenich carbon fiber prop back in 2007 on by 601XLB. After 2,300 hours for flawless service, I sent it in for inspection and I was told that it failed inspection and that it was not repairable. So I upgraded to the newer model. I can say that the new propeller is noticeably better. I had to replace the hub and spinner too because they are not compatible. I have had the new prop in service for about 5 years now.

Without elaborating, I will say I will always avoid any direct dealing with Sensenich as they have NEVER done for me what they said they would do. My issues with them are not subtle at all. I could tell a story that would make the hair stand up on the back of your neck.

Hopefully you can get your replacement propeller/hub/spinner from Zenith or Aircraft spruce.

Thanks for the info, Steve.  However, contrary to your experience, I have had excellent customer service from Sensenich!  I had to use a thin prop spacer for cowl clearance on my first prop and they made me the spacer and some custom drive bushings at a very reasonable cost and fast turn-around.  This new prop I already have in-hand - it was delivered on-time and I got great tech support from Don Rowell, the manager, on several questions 

Maybe I'm just lucky or you were just unlucky, but I'm a happy customer!

Hello John,

I got the replacement spinner directly from Sensenich. They are who warned me the old spinner would not work with the new prop.

And I forgot to say but yes, my replacement prop is a 2E0U5.
