I had problems with my engine/prop when I first got it, it would only achieve 4500 rpm. Kept onto Warrior who just said that's the prop we recommend for the best all round performance and fuel economy, balderdash! I went and seen Tom at prop revolutions who did the calcs and said you don't want one of those you wants one of these.... maybe Well turns out Toms guestimate was spot on my Optimax now revs at 5400/5500 depending on the day.
What I'm trying to say is talk to the professionals. They do the calcs for free, then for a little investment you could end up saving a small fortune long term.
Kept the original prop as a spare. Tried it about 2 years after changing to the new prop and Maverick seemed like a slug getting onto the plane, soon changed back again
