Nose ring on this engine turns out to be a simple job. The Hall sensor is located vertically in the SAP. Some engines have is set to the side and that tends to create a more difficult fit and set-up. Anyway, cutting 1/8" clearance around the sensor is not a big deal. Although I started this experiment with no nose ring, I came to realize over the first few dozen flights that the plane just wasn't behaving itself the way I was used to. Adding the nose ring cleaned the flight envelope; I recommend it if you soft mount the engine.

The ignition module mount was a gift from Todd. The least I could do is make good use of it.

BTW, the ignition wire and plug all fit neatly inside the cowl with about 1/4" clearance, as you can see in the photo above. That was not true for the ZDZ40 F3A. The cowl needed a clearance hole
