Folks:
I have been flying Warp Drive Propellers for 18 years and over 3,000 hours.
Warp Drive is my prop of choice. All three of my Alaska flights were made
with Warp Drive props. This prop is the only link between my engine and the
air we fly in. I would not leave home without the Warp Drive.
After many years Warp Drive now has a new web site:
http://www.warpdriveinc.com/
Of significant note is the 140,000+ props manufactured and shipped by Warp
Drive from their beginning in 1988 to the end of 2009.

I hope this doesn't turn into a Toyota type problem. I have been driving them for hundreds of thousands miles and never had any problems. Now I have one with three recalls, go figure.

Ron L/Gang:
Just got off the phone with Daryl at Warp Drive.
Warp Drive is not having any current problems with their props and hubs.
The failures referenced on this web site http://www.ultralightnews.ca/ are
ancient history from 1986, and prior.
Daryl said if anyone has any current problems with their Warp Drive Prop to
call him directly at:
1-800-833-9357.

Kolbers,
It looks like Warp solved it hub problem in that hub failure reports stopped
in December, 2005.
Jan 2001 - hub failure, Continental 10-240
Jun 2001 - cracked hub, 912s, two blade
Oct 2001 - cracked hub, jabiru, two blade
Dec 2005 - cracked hub, Rotax 582, CH701

Jack H/Gang:
I did not mention the above incidents in my previous post to the List
because they did not apply to Kolb aircraft. However, since you posted
them, please note they all apply to tractor aircraft and two blade props.
Darly told me the Continental 10-240 was an odd ball engine that broke props
and hubs of most any make or model.
Jabiru has never been able to successfully operate with a composite prop.
VW direct drive has the same problem.
The 912S's went to three blade Warp Drive props and had no more problems, as
did the 582 on the CH701.
Why would http://www.ultralightnews.ca/ publish an article like this after
the fact? Your guess is as good as mine. The article attempts to make Warp
Drive look bad.

John,
All this goes to show that no one make of propeller is good for all
applications. This is why certified aircraft are certified with one
combination of engine and propeller. If you want to break a crankshaft or
tear up a reduction unit, mount a high inertia stiff propeller.
The warp drive hub failure was not exclusively on tractor installations.
One was reported earlier in 1997 that was mounted on a Long-EZ.
It seems to me that if there is an alternative to a stiff high inertia
propeller that gives comparable flight performance, one should move in that
direction and in doing so reduce the stress loading on engine mounts,
fuselage cage and pilot.

*************************
Hi Jack H/Gang:
Not necessarily true. I don't think you could mount a "higher inertia stiff
propeller" than a two blade aluminum prop. Aluminum props probably
outnumber all others on GA aircraft, and a lot of experimentals.
Long-EZ not a tractor installation, but it was a direct drive installation.
Back to my original post in reply to Warp Drive failures, I am interested in
Kolb aircraft, not all the others.

John,
Then you will be interested to know that some Kolbs mount direct drive
Jabiru engines and some mount Rotax 582's.

Jack H/Gang:
Well...I was aware of that.
My flying buddy, John Williamson and I flew quite a bit together when his
Kolbra was powered by a direct drive Jabiru using a three blade Warp Drive
prop. John never had a prop problem.
I powered my MKIII with a 582 and a three blade Warp Drive prop. I had no
prop problem.
The Jabiru and 582 engines that had problems were trying to fly two blade
Warp Drive props.
What is your point?

My 70" 2 blade warp drive is pretty low on the list of concerns with me. The logic for the two blade is
my suzuki makes about 2/3 the hp of a 912. Works pretty good.
The only point I might make, and it may be nothing to worry about, is that once I was torquing the bolts and
one of the little outboard fellas decided to strip. -no, I didn't overtorque it, maybe someone else did once?
Anyway, since then I use a lower torque value for those. Not sure what the number is, I wrote it on the hub.
Not recommending this but it works for me and makes me feel better.
What I may do, just in the spirit of experimentation, is to take a few bolts of the same diameter and torque them
deliberately to destruction in the vise to see how close to the limit they really are.

Bob,
What size torque wrench do you use to torque the bolts on your prop? i.e.....1/2" drive, 3/8" drive, 1/4" drive?
The reason I ask is, You can find lots of guys on eBay that sell new 1/4" drive, cheapo (chinese) torque wrenches for about $30. Good enough to get the job done!!! I used it to torques the bolts on my prop, and may never need it again, but it worked just fine!

How about a big rusty old Ford wrench with a three foot cheater bar? heh heh
I have a full assortment of torque wrenches, both torsion and "clicker" types. I was a crazed tool collector for years.
-now finding the ones I have is a challenge.
I tested the one I use on the props for accuracy.
Jack, the hubs I have are pass-through types with a bolt and nut at each bore, unlike powerfin which uses a threaded half.

Bob, The last time I took my Warp Drive prop apart I put it back together using MS 21042 nuts instead of the nylocks that came from WD. There's no mistaking them for a hardware store part and they're half the weight of a nylock, too.

Don't tell Sensnich or Jabiru that because Sensenich makes a carbon fiber prop for Jabiru engines that Jabiru recommends, among others. See http://www.sensenich.com/products/browse/14/5/291/0
Don't tell the Titan Tornado dealer in Utah (Motion Aero) that since they've built and been flying for years both Jab 2200 and Jab 3300 Tornaods with Warp Drive props with no problems. They also have a 3300 with an IVO composite prop. See http://www.motionaero.com/Engines-Tornado.html and read captions under top two photos.
Why would John Hauck make such a statement that is demonstrably false?

Thom- I think the confusion is because of the Ultralight news article, and like John said it is very old news. The photos shown in the article seemed to show the hub casting for the three blade prop. I have a very old two blade with a hub like Larry's. I has been in a storm-blown rollover, plus my belly-up with the engine running. Plus years of exposure to salt air. I went and gave it a careful look-see after the initial report, and there is no visual sign of anything suspicious (no dis-assembly). It might be interesting to get ahold of Ultralight News and find out why they published it. Darryl at Warp Drive indicated that it may be from a problem 20 years ago. What kind of prop are you running? Have you ever had one come apart?

John,
It happens to the best of us, which is why I try to not make absolute statements.
I was just using a similar question you asked about ultralightnews. That website has been around a very long time and I'm sure the posting is very old and was probably accurate at the time it was made. As Larry noted, their hub design is quite different today.

Darryl told me the referenced failures were prop blades supplied by a
subcontractor prior to Warp Drive fabricating their own blades, which was
prior to 1986.
Many years ago I cut a GSC blade root and Warp Drive blade root in half
lengthways to compare the two, after I experienced blade failure on my GSC
prop. The Warp Drive blade was destroyed when it tried to cut through a 10"
yellow pine while mounted on a 912UL on a run away RANS S-12 at wide open
throttle. I'll post it if I can find it again.

Bill,
I've owned and flown IVO, GSC, PowerFin, WoodComp and Tennessee props on experimental and light sport aircraft, but never a Warp Drive or Sensenich. Not because I wouldn't, just because those listed were on and working well on airplanes I've bought.
Except for the plastic coating on the TN prop that started peeling when flown in the rain and the uneven pitch of the blades on that prop, both of which were fixed by TN free of charge, I've never had a problem with any of those props I've owned. Not many companies stay in the prop business long if their product self-destructs under normal use, does not perform well enough to get repeat business, or the customer support is poor.
