Europa-List: Re: Performance of 80HP compared to 100HP Rotax

Graeme,

If I was in your situation I'd be looking at this new prop from Duc.  Looks like
they've thought about the design and have done a fair bit of computer analysis
on it.  It claims to have a 'Constant Speed' effect for a fixed, ground 
adjustable
prop.  Sounds too good to be true maybe but worth a look:
