Duc Swirl-3. How much tip play is acceptable

[ndufty]

I was pre-flighting my friends Eurofox 912 today and noticed that each blade had some 'tip play'.

Does anyone know what is acceptable .. I am used to no play on constant speed props but I am guessing that more tolerance is allowed on Duc ground adjustable units.

The prop has 50 hours or so on it so everything is quite new.

Any advice gratefully received

Not sure how much is allowed but mine had more than I was comfortable with so I sent the prop back. DUC says it?s normal but from what I found some have it and some don?t.
