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:
Unaware of that technique.
From the Duo XT manual I have, 4.5.3.

STOPPING AND RETRACTING THE POWER PLANT
O Reduce speed to about 90 km/h (49 kt, 56 mph)
O Ignition OFF
O CLOSE fuel shut-off valve
O RETRACT power plant for 5 seconds
O When prop has stopped, RETRACT power plant
at 90-100 km/h (49-54 kt, 56-62 mph) fully
O Switch ASI to pitot head in fin
