Anyway, no hard feelings for the moderator edit. I just thought I'd clear the air on the real origin of "balls to the wall."

Great follow up post. Thank you for carrying on with your grandfathers example and a historically meaningful discription of the aircrafts performance state.

Anybody have an accurate weight for total install? Prop, hardware, governor?

I'm getting close to ordering my prop. It'll either be a 200RV or 74RV. I have an ECI IOX-370 w/P-Mags, Silverhawk and 9:1 compression, so the engine is rated at 205hp.
Anyone flying with the 74RV who can compare it to a 200RV or Hartzell?
Thanks!
Russ

Thank you for that bit of info, too cool. I did not know that!

Actually, the original, origin of balls to the wall, or balls out, was based on the flyball governors on a steam locomotive. When stoked and at full power the balls were all the way out, to the wall. They were brass too.
I can not say the aviation reference was not valid, but just not the first use of the term meaning "full power"

Hey Tom!!
I am making good use of the wing stands you passed along earlier this year. Hopefully another month or so and the second wing will be off the stand!
I did not realize you were based at Lake Norman Airport. The early entries in my logbook all have "LNA" as the airport from when I was a student at Davidson in the mid seventies, and taking flying lessons and working at Lake Norman Airport to earn flying time. The official designation 14A came to being after my private check ride.
Happy New Year!!

I am interested in hearing about this prop as well.

I have a 74RV on mine. 65 hours (ish). Angle valve, 10:1, .020 over, Pmags, cold air, injected. Wide open, 2600 rpm, 8000 feet I see 186 knots true consistently. I like it, but then I have the engine it was designed for. It's longer and heavier than the 200RV. If you have the engine to turn it, and don't mind giving up the ground clearance, weight and some climb in favor of a few knots......
I can say there is no way I would have purchased this prop without also having this engine and a plane intended for high speed, long distance cruise. Ground clearance alone would have dissuaded me.

I ended up pulling the trigger on one. She's sitting in our spare bedroom. :-)
My engine is the ECI IOX370, 9:1, Cold Air, Precision FI, PMags, rated at 205hp. So near the bottom end of the horsepower range this prop likes.
