This question is about the behavior of the Rotax 912 ULS.

This is the engine that it's in the plane in which I took my checkride, not
my Kolb. I also have rented it some since then. I realize that every engine
design is unique but I've never seen any engine do this. When you kill the
mags to turn off the engine, it STOPS, thunk. No wind-down at all. It's
actually quite startling. The CFI with whom I trained said it was perfectly
natural for that engine.

How say you all? Does this sound like normal behavior?

Ken and All,

It is normal for the 912 ULS stop turning immediately. It is also normal to hear a small squeak at shutdown if it has the slipper clutch installed.

Hi Ken:

I'll echo what John W said. When you shut down a 912ULS, it stops,
right now. It has 10.5 to 1 compression ration running through a 2.43
to 1 gear box.

Sorta reminds me of shutting down my Dodge Cummins. The Cummins B6
has 16 or 17 to 1 compression ratio. On shut down it shakes hell
outta the whole truck.

Take care and stay warm,

john h
