Re: Wooden Prop

'John: (And Others Who Have Inquired): Sorry for the long delay in getting
the info to you about the prop that Sensenich made for my F24R46A. It is a:
W86AB53. I wanted something that would give me a little more climb pitch since
we have (had) trees at the end of our 2000' grass runway. It was a little
sluggish getting out on the hot humid days with the prop that was on the aircraft
when I bought it. The trees have since been cut but I like the performance
and it really didn't give up anything significant in cruise. Think I lost 2 or
3 kts. Again, sorry it took so long to convey the info.

'Steve,

What is your field elevation?

What is your current cruise and what setting.

I will ordering a new wood prop, my field is at 7050.

'Jamie: We're running in the 95 to 98 kt range at 2150 to 2200 rpm. The
field has an elevation of 540' . We're off the thick medium-cut grass in a little
more than half the field length. The plane had a W86RB60 on it when I bought
it. It got out of the field but it wasn't nearly as quick to rotate as the
current prop. I seem to recall that it had about 98 to 100 kts. before the swap.
It was O.K. but not what I needed. I also want to point out the we're using
the six bolt hub as opposed to the eight bolt. That impacts the Sensenich code
in the prop number. But, they said they can build the desired prop with either
six or eight holes.
Hope this info helps a little with the decision one way or the other.

'Hello Steve,
I'm the one you called when you were searching for a prop after
buying your ship from Bob B and told you about this jewel. This prop
for those who find it sounds odd is a very dinstincive looking
profile. It has, for lack of better description....breasts. The
Ranger has a short 20 spline and Warner hubs which are nearly always
used on the Ranger limit the hub thickness and therefore the root
profile near hub is not very aggressive on the standard R series. On
the AB series the root profile is way thicker but since it won't fit
the 4.5" long 8808(?) hub they have a stepdown at the hub crush plate
diameter to get what would be about a 5.5" thick hub down to 4.5
thick. I do not know of other wood props that do this. It is very
unique. This stepdown gives the look of a bump on each side of the
plate on the camber surface of blade. This lump requires an extra
lamination that is cut through at the hub and tapers in a teardrop
shape as the blade profile flattens. This is seen readily by the
rescorcinal glue line. Very unique.Also the tip is ever so gently
squared off but not perpindicular to blade axis. Whoever thought of
this profile gave it some thought. It's neat to just look at and
point out as 99% of observers never notice it. That sound about right
Steve?
We are running an 86AB54. 2400 rough washboard deep turf strip (this
makes for spectacular short stops, brakes will last forever!) at 900
elev. On our 880hr 200hp at 2350lbs it will be wheels off at
1600'w/half flap. As far as in flight our ship is not a fast one but
those numbers sound acheivable with proper rigging.

'Hello:
Your assessment of the prop and description are stated far better than I could ever have thought of describing it. And, yes, those teardrop "bumps" are also best described as you have mentioned. Overall I have been very pleased with the prop and understand that other props, including the one suggested by Jamie, may work well also. Bottom line is that it's great to have this forum in which all of this info can be shared for the individual and combined benefit of those who understand and embrace the Fairchild mystique' !
Keep 'em flyin'!!!
