Subject: | Fixed pitch to constant speed |
I have a RV8A with an O-360 and fixed pitch Sensenich prop. -I am conside
ring changing to a constant speed prop, but I am concerned about the added
weight on the nose of the plane. -My plane is on the nose heavy side as i
t is, and I would not like to make it any more so. -I am looking at the W
hirlwind RV series. -Does anyone out there know how the installed weight
of a Whirlwind prop compares to the fixed pitch Sensenich? -The Whirlwind
prop and spinner weigh in at about 38# according to the folks at Whirlwind
. -I was hoping to find out the weight of the Sensenich installation with
out pulling my prop.
Thanks,

Craig,
I did this conversion on my 8A about three years ago. After reviewing all
the performance data on the various CS props available, I selected the
Hartzell blended airfoil. I have an IO-360, 180 hp engine so the engine
weigh is the same as yours.
Looking back over my W&B data, I can tell you the Hartzell was 13 pounds
heavier than the Sensenich. I have two Odyssey 625 batteries mounted just
aft of the firewall. I considered moving one of them to the aft mount
location but decided to wait until after flying to see if it I had a nose
heavy problem or not. Bottom line, I did not see much difference so I left
the batteries where they are.
As I did with the Sensenich, I put a 25 pound shot bag in the baggage
compartment if I'm solo and no baggage. My W&B does not require this, but I
find it helps.
I can tell you the performance difference between the Sensenich and the
Hartzell was far more dramatic than I anticipated. You will love the
change. I have a couple of hotrod Lancairs at the airpark and while they
eventually pass me, I give them a surprising run for their money.
BTW - I'm using the PCU-5000 governor and am very pleased with it. If you
need a governor control cable bracket let me know - I have a new one sitting
here I bought from Van's by mistake for the RV-10.

Craig,
Do you have your battery in the back?
I have an IO-360 200 Hp / Hartzell BA CS prop (great combination) and have
no issues flying solo with full fuel or near empty and no weight in the
back.
One note I have dual G3X and back up EFIS so I suspect my panel is lighter
than a 10 year old build with steam gauges.

I have a RV8a with a IO-360 200hp which is a little heavier than your engine
plus I have constant speed prop and have been flying it since 2002. That
being said I do keep 25 lb. of lead shot in the aft baggage compartment and
a few tools which keeps the elevator pretty even or level in flight thus
creating less drag. When landing it also helps with a lot less trim. I have
confess my best landing are when I have a passenger in the rear seat and
nothing in the aft baggage area

A 20-year Project
A 42-foot schooner isn't a big project for a ship-building company. It's a different
matter if you're the one doing all the work. In the early 1990s, Dr. John
Vardiman decided to build one from scratch. It took over 20 years to complete.
What an great story of perseverance...

Thanks, Matt. That is another one of my dreams. When I was a teenager, there
was a doctor building a boat about the same size as this one of his own
design which he had in the water at Bellingham, the local port. I remember
thinking that he was an old man and would never get to enjoy it. I think I
am probably older now than he was then, and I do understand finally what he
meant when he told me he would enjoy it even if he never lived to see it
finished. He too was a medical doctor, I think his name was Montour, but
that was over 50 years ago now.
