sensinich props

Posted: Fri Feb 17, 2012 8:55 pm
by Rick DeCiero
Hello,
I do not plan on putting my rebel on floats and am wondering if anyone is
using the Sensinich 74"dia x 58" pitch. What is it's performance verses
the 56" pitch that Wayne has used on some float planes. Will the 56"
give 100 knot cruise? Will the 58" turn enough revs for 1200 foot grass
strip takeoffs?
Any and all comments will be appreciated.
I have a 2" prop spacer by warp drive and a 12" UMA spinner for sale
both parts are unused the spinner was precut by UMA for the warp drive 3
blade configuration. If anyone is interested just contact me offline at
rsdec1@star.net so we don't clog up the pipe here.
Thanks,
Rick D.

Rick, just to clarify.

Bob P's Rebel, on wheels, with 150 H.P. O-320-E2D is running a Sensenich
74DM x 56 pitch It gets a good 105 knot cruise (dirty with no gear leg
fairings, etc) Takes off in about 200 feet (at around 1375 pounds)! Will not
readline in cruise at full power, but just about makes it there, so prop is
pitched course enough.

Howard's on Amphibs with the same engine and a 74DM x 52 pitch works okay
according to Howard, and does not readline on climbout. I presume it
readlines in full power cruise, but I can't ever get a straight answer out
of Howard. He cruises apparently about 2 M.P.H. slower that Jack Weibe and
Les McGinnus with their 160 H.P. / Warp Drive pulled amphib Rebels and got a
little behind them coming home from Oshkosh last year. Howard's amphib does
get off in a hurry with this prop though. He goes up my 2000 foot runways 2%
grade ON GRASS and over the 90 foot trees at the end, with about 200 feet of
clearance. That is a total climb of about 330 feet in 2000 feet with FULL
Tanks and himself on board! It ain't no dog!

Do you mean a 12" UHS spinner??

WAYNE,
Thank you for the detailed info. As you have probably figured, I am going
to abandon the Warp Drive prop and go with the Sensenich. It seems like
the 74DM x 56 pitch is the way to go, 58 pitch is probably too much for
some of the short fiels that I frequent. The factory mentions the 56 for
climb and the 58 for cruise.

Other airframe info = firewall back 3", spring gear

Yes, the spinner is a 12" UHS. I just can't get those new UMA

1 1/4" gauges out of my head. I saw them at sun n' fun and they are beautiful but pricey.

Also the 2" spacer is for an SAE II pattern with 7/16" dia bolts.

Bye for now,
Rick D.

Rick, If you want cruise (vs climb) you probably <could> go with the -58! If
it turned out to be too course any good prop shop can make it finer for
about $250 Cdn. The same goes for the -56, if it's too fine have it twisted
courser! Flip a coin and pick one or the other! Is your engine 150 H.P or do
I remember yours being 160, thus you would need the courser prop for sure.

Blue skies,
Wayne

Wayne,

If I read your description about Howard's Rebel and his 74x52 Sensenich, and
he keeps up with the 160 HP Rebels with Warp drives (assuming the WD are
pitched for max cruise at red line), then the Sensenich 74x56 is the ticket
of choice, one would think. I am still waffling on the prop choice. Metal is
not an option for me (I'll change someday if I get floats), I'm afraid of the
C&G. But I am considering a wood Sensenich 74x56. Is it reasonable to assume
similar performance from the wood prop? The price is right too!

Bruce, I'm no propellor expert! I can just relay the proven performance on
what I have installed. I know Howard discussed at length with someone at
Sensenich about what prop he should get and then ordered through MAM to get
the OEM price. (I think he went finer than they suggested though!)

Why not contact Sensenich's tech department and see what they say will
compared to the 74DM metal propellor in wood. Phone is 1-717-569-0435 email
is ez@sensenich.com website is www.sensenich.com

How 'bout -56 on one blade and -58 on the other blade. Then you'd have the
best of both!

Wayne,

I talked with the wood prop guys in Florida several months ago.
Sometimes I get the feeling they will tell you anything you want to hear to
sell their product. I will call the metal prop manufacturers tomorrow and see
what they have to say. Thanks for the info.

I have a 150 HP version of the O-320.

Bruce G.
The 2" spacer is for the warp drive 3 blade hub that would be used on a
150 HP lycoming O-320-E2D with an SAE II flange. It was purchased
through Warp Drive and is made by Saber Mfg. Selling for $200.00 +
shipping. It is brand new.

Both Sensenich wood and metal prop shops said the metal blade out performs
the wood blade by 2 or 3%. The metal prop has a smaller cord and is a more
efficient airfoil. I think 3% is not a bad tradeoff for 30 lb. difference in
useful load, not to mention what it does to the C of G. The question becomes
will it out perform a WD?

Bruce,
The prop itself is not availabel. However, the 12' UHS spinner with the 3
blade factory cutout for a warp drive prop and the 2" spacer will be
available. Both parts are for a Lycoming O-320 with an SAE II flange and
7/16 dia bolts. Call me or e-mail me directly if you are interested in
purchasing them. I am in Massachussetts.
