Subject: | Re: prop for 447 on UltraStar? |
I bought a Tennessee prop last year I think it was when I was flying the Duc. It
was great, and it looked great. Still looks good. They make some mighty fine
looking stuff, and the price is good too. Never thought I'd like a wooden prop;
now I do. I also fixed the old prop with Gorilla glue and fiber glass after
some ground damage. It was an emergency repair to meet a flight schedule. So
I am ever more convinced about the virtues of wood prop. I doubt you'd do better
than the same prop I had on the 430. When I called them the fellow that answered
the phone knew what prop I needed and sent me that one.
447 is a rotax,,, I had the Cuyana, in any event the Tennessee prop was very good
choice for me, and pretty as it gets.

My UltraStar currently has the original Cuyuna engine with the 50x30 Culver
prop. I just acquired a 447, which I plan to install. Can anybody tell me
what is a good prop for this combination? I believe (need to confirm) that
it's a 2.58 ratio B box. I'm thinking 3 blades due to the limited diameter
possible on the US, can't go 4 blades and fold the wings... perhaps even
smaller than 50" to give better ground clearance?
A friend gave me the engine in the interest of me being quieter than I am
with the 447; a number of people have commented on how loud my plane is.
Also for anybody who's flown the US with both engines, how much performance
increase should I expect? I calculate about 350fpm better climb in theory.

Ellery,
I'd like to add my congratulations to you for a job well done. Emergencies handled
well are what training, practice and experience are all about. PLEASE keep
us posted on the prop assessment by NTSB. Has Warp Drive expressed interest in
getting it back for their own evaluation?
Care to share your plans/thoughts on re-building or building new?

Thom Riddle
I am sure Warp Drive will be interested in those prop blades.
However, I don't think they are Warp Drive Blades. To the best of my
knowledge Warp Drive has never built anything but solid carbon fiber blades.
The blade that failed on Ellery's MKIII looks like a honey comb core blade.
Another peculiarity of this failure is the area of the blade that failed,
the trailing edge.
If I am wrong, promptly correct me. I plan to call Daryl in the morning and
will confirm if they have ever manufactured and sold honey comb prop blades.
All Warp Drive Prop Blades have the serial number and maybe the weight of
the blade inscribed in pencil on the butt end of each blade. Also, one
blade of a two or three blade prop will have the data sticker on it with SN.
I have flown and been sponsored by Warp Drive since September 1993. During
that time have flown my MKIII with Warp Drive props mounted on 582, 912UL
and 912ULS, for more than 3,000.0 hours. The worst situation I have
encountered with the Warp Drive Prop was when an 18" section of 1.5" exhaust
pipe with a 180 degree and a 90 degree bends, broke and went through the
prop at wide open throttle. Was climbing out when I heard and felt a huge
explosion. Had a slight vibration. Made a precautionary landing at the
next airport to check out the damage. There was a ding in the leading edge
of one blade. Flew the remaining 11 miles back to my airstrip with no
further problems except the slight vibration. Was lucky the prop did not
kick the pipe into an aileron, wing, or tailboom. However, it did get the
bottom frame of my radiator which was mounted between prop and tail of
fuselage cage.

Dana,
Can't comment first hand on a prop for a 447 powered UltraStar but had a PowerFin
on my 447 early Firestar and an IVO on my 377 powered even earlier Firestar.
Both were good props but I now have a Tennessee prop on the Slingshot.
I really like the TN prop and the company is unbeatable for customer service.
Customer Service Story:
When I bought the Slingshot with this prop, it was black plastic coated from the
factory per the builder's request to match his color scheme. When I flew it
through a light rain shower, the outer 6-8" of each blade showed damage to the
black plastic coating, none to the blade itself. At that time I measured the
pitch of both blades since it was not turning up as close to redline as I wanted
in S&L flight. It turned out there was about 3/4 degree difference in pitch
between the blades. I removed the prop, called TPI and they told me to send it
back, which I did. Per my request they reduced the pitch a little and evened
them up and refinished it with their natural clear coat polyurethane, a true
work of art. I wish I had a photo of it to post. They sent it back and asked me
to report back after flying with it. The pitch difference was now almost not
measurable and it turns up to within 50 rpm of redline, just like I asked for.
They did this absolutely free of charge, even though I was not the original
purchaser of this over 5 year old prop.
http://www.tn-prop.com/prop.htm is now my first choice in prop vendors where a wood prop is appropriate.

Subject: | Re: prop for 447 on UltraStar? |
Ron, Thom,
What I'm really looking for is input on prop pitch, diameter, and number of
blades... of course pitch doesn't matter if I get an adjustable prop.
I like wood props too, but a tough prop like a WD (Ellery's adventure
notwithstanding) is attractive for an airplane with as low prop ground
clearance as the UltraStar.
I'm leery of Powerfin, because I watched a Kolb crash after the Powerfin
came apart apparently due to internal damage... they're just not as robust
as a WD or Ivo. I had good results with a GSC adjustable (wood blades) on
my PPG. I'd try the original prop, but the rotation direction is opposite.
Hmmm... I see I may have to change out the redrive, if it's a 2.58 ratio as
I believe... Tenesee calls for 58-68" props for that ratio; I'd need a 2:1
redrive for the 50" prop that would fit on the US.

Dana:
US is a good little aircraft, but also had some weaknesses. One was prop to
ground and tailboom clearance, which limits max prop diameter to 50" on the
Cuyuna and Kolb reduction drive.
On my 447 powered original FS, I was dialed in with a Jim Culver 60X30 two
blade wooden prop with polyurethane leading edge.
I think if I was going to power an US with a 447 I would go with a 3 blade
WD and nickle steel leading edges on the blades.
Position of gear box and prop flange will dictate max prop diameter.
Better yet, sell the US and get an original FS powered with the 447 and a
60X30 two blade wooden prop. With a wind shield and cockpit you can
actually read a map while you fly.

Dana,
There is no arguing against the advantages of an adjustable pitch prop. I had an
in-flight adjustable GSC on my old Titan and had no complaints. Did you know
that TN Prop makes a four blade? Not pushing any brand, just relating my experiences,
as are the others.

Can't do a four blade. I need to fold the wings.

Yes, that's why I'm hoping an extra 5HP with a three blade prop might give
me a bit better performance.

From what I understand, the WD has too much inertia for the B box, no?
>Position of gear box and prop flange will dictate max prop diameter.
Yes, that's one issue that concerns me... the Rotax gearbox puts the prop
shaft closer to the engine crank, i.e. closer to the ground (with the
original engine mount). I might gain boom clearance, but lose it on the
ground side.

... and lose the visibility. Not that I haven't thought about it (or
better yet, a Firefly)... but it isn't in the budget right now.
Hmmm, I wonder what I could find an engineless FS or FF for? I've got an
engine...

Subject: | Warp Drive/GSC Prop Blade Grip Comparison |
Folks:
We had a RANS try to take off, WOT, no pilot and no wings at our airport.
The RANS went through some pine trees and took off all three Warp Drive
blades as they tried to cut down a 10" pine.
We disected the WD blade grip as well as a blade grip off my GSC wooden prop
that came apart on me and my 582 powered MKIII. Here are photos
illustrating the difference in the composition of the two different props.
The WD blade is built up of solid carbon fibers that run from the blade tip
to the blade grip/butt, around a metal ring and back to the blade tip.
The GSC blade grip has a hole drilled through it that is elongated to allow
ground pitch change. Not much keeping the blade in the hub.
