Subject: Re: RotaxEngines-List: Re: reverse prop rotation at shut down

I believe I was the one who started this thread. The reverse rotation  
occurs occasionally on my 912UL if the rpm at shutdown is too high. It can go 

backward for as much as 3 complete turns ! (great for backing into parking  
spaces)
 Of course I don't have a slipper clutch so that isn't the  problem. I have 
had the gearbox re shimmed and that didn't help. I changed  to a lighter 
prop which did help a little.
Anyway, I think I have the problem solved. If I shut the engine down  with 
the engine rpm about 1200 or less,it doesn't happen. Sometimes you can see  
at prop stoppage that the prop blade wants to flip backward but at that low  
rpm ,it doesn't have quite enough inertia.
