MT Propeller sensor and slip ring bracket – 2

01 Jul 2005 MT Propeller sensor and slip ring bracket – 2

Update 20210918: I didn’t install the Eggenfellner Subaru engine, so any post that references that can be ignored or used as a cautionary tale about how to avoid wasting many years and $50k.

The first time I installed the bracket for the MT Prop controller I put the bracket on the outboard side of the slip rings. This was a mistake, since it interferes with the cowl. I re-did the bracket and put it on the inside of the slip ring. I think this is the recommended way to do it, but I lent out my videos, and I don’t recall.

Notice the lightening holes.

I have not yet riveted it yet, since I want to get the aluminium anodized, first. Not sure if anodizing riveted parts will work. The Eggenfellner PSRU looks very cool. Now I have to decide if I anodize to match the deep blue of the PSRU, or some other color. Hmmmm.

Good things about this Eggenfellner Subaru installation are that the mounting studs on the PSRU were already installed and ready to go. The MT Prop is really a very high quality propeller. This bracket is solid, and should be happy there for thousands of flights.

Here is the wiring diagram from the installation and owners manual:
