 |

Guys,
Back in 2004, we became concerned about the future availability of the
original V-530 prop blades. Carl and I had been to Vpered in 2000 and
placed an order for 10 sets of new blades which never came to fruition. .
You can go to their website and it looks like they are still being
manufactured, but I wish you all of the luck in the world trying to get
anywhere with them. We began to talking to Jim Rust at Whirl Wind in El
Cajon, CA about designing and building a replacement carbon fiber blade for
us. Passing thoughts were given to recreating the same paddle blade as
original. Carl and Jim worked together on the design of our V-530C blades
(pictured on our website www.m-14p.com ). In 2006, I wrote the check and
signed an exclusive contract for the design and tooling costs of these
blades: M-14P, Inc. V-530C hollow carbon fiber blades.
Our guiding philosophy at M-14P, Inc. is maintain the M-14P and Yak as close
to its intended purpose. The American psyche is one that wants to
innovate, change, improve, economize and make better. I love that.
However, we are keen to take a step back and question "Why did they do
that?". The V-530 propeller hub is virtually bulletproof and field
serviceable. The failures I have seen are owner induced: Severe
over-tightening of the blade nuts and leaving the hub unprotected and in a
position that allows the ingress of water into the hub over a lengthy period
of time. For those 2 reasons, I unequivocally recommend the V-530 to a 52
guy. Model 12, Sukhoi and Yak 55 guys competing at the higher levels of
acro will want/"need" an MT prop. Repair costs are markedly different when
you ding an MT versus a V-530C or W-530 set of blades.
We wanted a blade that was:
1. A direct replacement of the V-530. It is. New ferrules are
machined for the blades. In years past, people have tied to reuse the
Russian blade ferrules.
2. A blade design that would match the V-530 performance, and if it was
any better that would be a bonus. The V-530C blades have done that. I have
2 great Yak 52 owners that have done several series of test flights on our
V-530C blades and are meticulous in the data collection and recording. We
have achieved our objective, but are still playing with the optimal blade
angle setting on the V-530Cs. Our next round of test flights are comparison
flights for the original blades vs. M-14P V-530C blades versus WhirlWind
W-530 blades. I will post the results to the list when we are finished.
3. Economical. Both the V-530C and W-530 blades sell for $6,000 USD
per pair. I talked to a customer this past week, who received a quote of
$18K+ on an MT prop. I believe the Italian blades are $10K + a pair.
Someone can correct me if I am wrong. I also believe they are a wood
composite, not carbon fiber. The also manufacture spinners and I requested
a quote for 10 units and never received a reply. Rick Volker was flying the
blades at one time, perhaps Eric will want to comment on Rick's experience
with the Italian blades.
The prop diameter on the V-530C blades is 98". The blades weigh almost the
same as original but the polar moment has moved closer to the center of the
hub. (Whirl Wind W530 diameter is 100" and original is 94.5")
The problem that Warren Hill has experienced with his new W530 blades was
discovered in our shop, as we were attempting to assemble a hub with our
V-530C blades. Whirl Wind does not do any hub work or carry any parts for
the V530 hub. We do. We are able to perform the work also and we
statically balance a prop assembly before it goes out the door. As a
business courtesy, if you are going to use M-14P, Inc. as your source for
technical support on the prop and are going to buy W530 blades , I would
appreciate the order . You will pay the same price for the blades whether
you buy from me or from Whirl Wind, but I receive a commission for the sale
if they are purchased through M-14P, Inc. The time and money spent
developing this blade program has been a large investment by M-14P, Inc.
with an eye on the continued ability to keep your aircraft flying
economically and well.
Jim also has a carbon fiber spinner on the burner.
