915is Ground-Adjustable

[VictorV]

Has anyone installed a ground-adjustable prop on the 915is? I'm trying to figure out what
my options are. I'm Light Sport so I can't use the constant-speed prop until (if/when) MOSAIC
comes to fruition. MOSAIC will most likely allow use of a single-lever control so my only
option would be MT using the Stock Flight Systems controller (EMU) when the time
is right. For now I will be fine with ground-adjustable.

KF does not have a recommendation since they have not tested any yet.

Hey Victor,
I haven't tested (or even mounted) my prop yet as I'm still in early stages of my build with a 915 but I did purchase a DUC ground adjustable prop which can be upgraded at a later time to a constant speed prop. May be worth looking into but there isn't much info or user reviews I could find. Only time will tell if it was a good decision.
DUC USA was extremely easy to work with and very responsive. I went with a 4-blade 75" option but for better STOL capabilities, a 3-blade 72" might have been the better choice for a 915. I will definitely save on weight compared to an AirMAster or MT and the allen ket adjustability looks to be very simple. For future, DUC does sell an hydraulic/electric control system, which can be mounted and used similar to MT and Airmaster.
Just an option worth considering.
Here's a link to DUC's brochure

and a quick video of what my prop looks like

Thanks Kevin. Nice looking prop. I am learning that there are many things to consider when choosing a prop.
I'll talk to the guys at Duc. Were there any others you considered?

You might reach out to Sensenich. They make some ground-adjustable's for other Rotax, and may have an option for you. I can't speak highly enough of my ground-adjustable Sensenich that I put on my Lycoming powered Kitfox 5 Outback... it's such a nice prop.

Trent Palmer is using a NR/Luga 3-blade ground adjustable with his 915.

I just received Sensenich's new STOL prop for the 915is. It's a bit larger diameter than I was originally wanting to go with, but going to try it out anyways. 82" three-blade ground adjustable composite with the pin adjustment system. 14.75 pounds for everything (hub, blades, hardware, etc).

I'm definitely interested in hearing how it works out for you. Seems like many of the props I have seen are closer to 72" so 82" seems big.

A picture's worth a thousand words!

I have a friend with a Sensenich adjustable prop with the pin guides.

When setting pitch on these, make sure to double check them with a protractor. My friends individual blades can vary by more than a degree with just the pin.

My 2 blade NR(luga) is 69.7" long and 9.8lbs with the 2" extension, h/w and spinner. No data as of yet.
