Recently flew a 2008 Duo with the 5 bladed sustainer.

Started very fast and beautifully with very little height loss.

When it came to putting it away, it was, however, difficult to get it to stop rotating.

Yes, put it half way retracted and yes, used the decompression to also slow it down as advised. Only by reducing airspeed to close to stall and holding it there, did it finally stop.

The days was hot. OAT at 3,000' was 32C.

Of interest (as it seems counterintuitive), why does the decompression work to slow it down?

Richard, perhaps you skipped a few critical steps, or did them but
neglected to mention this.

1. Either turn off the ignition, or shut off the fuel, or both.
2. Partially retract the engine, perhaps 30 degress tilt.
3. Open the decompression valve for a few seconds and then CLOSE the
decompression valve. If you continue to hold the decompression open
the prop will NOT stop.
4. When the decompression valve is then closed the prop should stop
pretty quickly.
5. Complete retraction.

Hope this helps
