Hi all, sorry to cross-post to 2 forums. Generally I don't do
that, but the RV-14 forum doesn't get any posts so at least
this one will go there.

As with all the other kits for the RV-14, Van's is taking
what in builders lifetimes is "forever" getting their FWF kit
out. I need to get some things fitted up, now that I have
my engine hung, such as the prop control cable.
So I want to buy my prop governor, and start working on that.

For the IO-390, it uses a .895:1 ratio governor, and on one
of the Van's planes they used the Hartzell S-1-79. The lever
comes clocked to 180 degrees. From a bit of googling, it
sounds like *perhaps* the Hartzell's are an older design, but
I hear conflicting things like the S-1 series were developed
for Van's, and have more oil flow.

Then, there is the PCU5000X P-520-029/A-947, that is the proper
gear ratio and model for the IO-390 that I've installed.
They claim to be newer designed, with high oil flows too.

Seeing as though Van's is so ultra-slow in getting the FWF kit
together, they don't have stock of the governors for the IO-390
at all. I'd like to get one ordered, and can get a PCU5000X
for about the same price as the Hartzell's that Van's sells.
I know some people love the PCU5000X. I know many who
have a Hartzell. Does anyone have any info on either that
would push me in one direction or the other?

I love pictures, if you have any, too.

Two planes (RV-8A and RV-10) with the PCU500X and they have been flawless. I got both via a group buy on Van's Air Force so price was less than the Hartzell.

You might want to call a couple of prop/governor overhaul shops and get their opinion as I have heard second hand they prefer the PCU5000X.
