Hi guys
I have over 400 hours now on a 70 inch IVO IFA Ultralight prop with a 912 UL on my Vixen.
Have no problem getting full RPM on takeoff and could also "overload the engine" with excessive pitch on cruise if you wanted to. I think it is a good idea to have a manifold pressure gauge with the in flight props.
I would be careful trimming the tips with the chance of unbalancing the prop.
They are pretty smooth. Be a shame to bugger it up.
Happy Thanksgiving.
