Hi Graeme
I have just changed my propeller from a woodcomp scimtar to a SR3000/W
and have found that now in normal cruise i need a slight right rudder
input to keep the slip ball balanced,
This is because the new propeller is more efficient i believe,
It also gives me a improve 3kts in the cruise, On a sustained full power
climb to 5500
last week my oil/water temps remained within limits, Something i couldn't
say for the scimitar blades,
regards
Ivor
