I've got the opportunity to buy a 3-blade Hartzell (C3YR-1RF) for the RV8 we're building. We've already purchased an Aerosport 0-360 A1A for the project, and I'm wondering if anyone else has tried such a combination.
In particular:
What about the effect on CG? I know that constant speed props tend to make some 8's a little nose heavy, and this is about 14 lbs heavier yet. We're still finishing the fuselage, so I don't have any guess where the CG is going to finally fall.
Are there any harmonic problems with this combination? Again, all I have is second or third hand anecdotal information about substituting 3 blades for 2 on other airframes and engines. FWIW - the prop was recently removed from an -8, and the combination is apparently approved on the Mooney M-20C.
Any first hand experience would be welcome.
