PC6

Der neue Prop ist ein Traum!!! Der Porter steigt schneller. Das teilten mir
2 Piloten unabhangig voneinander mit. Zwar mit geringerem Anstellwinkel,
aber dafür mit besserem Speed. Umlaufzeiten fruher auf 4000m lagen bei
16-17 Minuten, nun bei 15. Es ist nicht unser Ziel derart schnelle Zeiten
zu fliegen, Aber es fiel auf...

equipped with an MTV-15-B/203-58 propeller operated this aircraft -
propeller - combination for 2200 hours without any problem and wants to
thank MT-Propeller for the excellent product and support.

The pilot, Rodrego Cruz from Astra Charter in Ft. Lauderdale reports the
interior noise level is noticably less. It is much smoother and feels like
a turbine. It gets attention at every stop with folks asking what kind of
plane this is with the 4-blade props.
The MT props have a neat chirping
sound made during taxi. Time to climb is reduced and cruise speed at same
power settings is a few knots faster.

Customer Feedback of Jim Parran, owner of a Merlin IIB.

I consider myself a strong supporter of your product and phylosophy to assist your
customers needs to the end. My old props were well used for almost 40
years and due for at very least one serious overhaul. Hartzell and McCauley did
not want to really talk with me about replacement options so I expanded my
search and found you.
I am very glad I did. Your ''can do'' attitude and
quality of product is truly amazing. It would be an honor for me to support MT at airshow events when my schedule permits when I start actively flying again.

Thanks to you, Martin, and the entire MT crew for your work on my
propellers. I could not be more pleased with their performance and
appearance. Happy New Year to you all as well.
Aloha,

Customer Feedback of Tom Redman, owner of a Merlin IIB.

I had an opportunity to fly for 2.5 hours yesterday and knew you would
be interested in a little information and my comments regarding my 1967
C-182K Skylane. As you know it has a stock 0-470 with 270 Hours since
Zero Time Rebuild. Rod installed his
F. A. T. (Forced Aeromotive Technologies) Supercharger in December and in January, we installed a new (M T) Two Bladed Prop. Before the installs, max climb was about 800- 900 FPM w/ the conditions below.
These two installs have Doubled the ROC.

All I can say is; WOW! With the Supercharger installed it will maintain
28” Hg Manifold Pressure well above 12,000 ft (That’s as high as I’ve
flown it since the install).

Since the new Prop install two weeks ago, I haven’t had a lot of flight
time, but here are the results from my flights yesterday.


Columbus, NE (OLU) – 1460’ MSL
46-54 Degrees F
Pressure 28.4
420# – 2 Ft Seat Passengers
170# – Baggage Compartment


Max Climb
28” Hg Manifold Pressure
90+ MPH
2650 RPM Prop Speed
Not yet Dynamically Balanced but runs as Smooth as silk
Climbs at 1600 Feet Per Minute on takeoff up to 4,000 ft MSL –
(conservative)

This aircraft flies and performs better than other Skylanes I know of
(in my very limited experience). It is even more responsive to the
throttle with the new Prop (due to the 19# lighter weight I assume) and
much quieter at 2400 RPM or less. One really has to fly it to believe it…

Thank you Gentlemen for the Great Products and Service. This Airplane
may turn out to be one of the safest and fastest 182’s around. An ideal
Cross Country Aircraft.

My Best Regards,

Tom Redman

I have just acquired a new MT propeller for my Mooney M20K (231). I fly in
the western United States with high density altitudes. I selected the MT
prop to gain improved performance for climb.
I am very happy with the results. My take off runs are shorter and my rate
of climb is about 300 feet per min greater. This improved performance is
both at sea level and airports at 6500'. Cruise speed has not been
negatively affected. The propeller is quiet and no vibrations at all engine speeds.
MT has developed a winner!

MT Composite Propeller Experience on my G36
By: Craig Sommerfield [2007 Beech G36 w IO-550-B]

I was getting the itch for a bit more performance from my G36 when
I read the article in the ABS magazine about the new MT composite
propeller approved for my plane by Flight Resource........more (pdf)

Example of Beech with MTV-9 Example of Beech with MTV-9

Als Pilot der HB - LTM ( erste umgerustete PA42-1000 /LS400) ausgerüstet
mit Ihren 5 Blatt Propellern (MTV-27-1-E-C-F-R(G)/CFR()250-103) habe ich
jetzt 600 Std. ohne die geringsten Probleme und Beanstandungen geflogen.
Speziell in vereisenden Situationen sind mit Ihren Propellern im Gegensatz
zu den 4-Blatt Propellern nicht im Ansatz Probleme mehr aufgetreten...
In guter Erinnerung ist mir der Flug am 20.07.08 von Catania LICC 14:14 LT
nach Mollis LSMF 16:30LT . Es hatte starke Vereisung und Turbulenzen über
die Alpen und im Sinkflug (echtes Hundewetter)
Ich kann Ihr Produkt nur weiter empfehlen speziell auch im Bezug auf Lärm
und Vibrationen, mehr Bodenfreiheit und besseres Startverhalten des
Triebwerkes!

I wanted to thank each of you for all of your time and effort in helping us
with the Super Chipmunk.
With the change in the low pitch stop to achieve 2600 RPM as well as the new MT governor and accumulator the plane is performing flawlessly throughout the entire range of it's capabilities.
The accumulator works great - it is impossible to get the propeller to
underspeed now even on the longest upline or tumbling pass. Overall, the
MTV-9 is a HUGE improvement of the originally installed prop that we had before.
It literally pulls the plane through the figures and slows the downlines
making it MUCH easier to fly a sequence down low and up front.
We have the Indianapolis Air Show middle of August and we will ensure that MT gets credit where it is due.

This mail is for congratulate all the MT team for the succes we get with
the Cheyenne 400LS STC we installed.
Finally a week ago installed both MTV-27... on Cheyenne 400LS and
was a great succes, the customer is most than happy with the STC, the
aircraft perform much better than with the Dowty system, the sound level
in the interior is amazingly lower and the aircraft really has increased
the speed in "at least" 6 Knots, really after balancing we get a real jet
like feeling.
On our side, as prop guys , i can only say congratulations for a great job
in designing, manufacturing and selling this prop sytems
, i have installed
many, many, STC, but this one, even being done on an important turboprop,
was delightfully simple, and i ever say that the simpler it is for us the
most you work on the design, this is the case because everything was
straight forward with no even the minor problem.
We run the engines with the old props and took notes of all the parameters
in ground (torque, RPM, Fuel flow, Temperarture) then we removed the props,
installed the new MT, set the Flight Idle, correct a minor difference
between the prop levers and then goes directly to the dynamic balance, we
start with a reading of 0,46IPS on engine 1 and 0,28IPS on engine 2 and
after the second run of each engine they went down to 0,02 IPS engine 1 and
0,04IPS engine 2 the aircarft took off to San Pablo Brasil on a 3: 30
flight and at the arrival the pilot call me exited with the performance of
the plane the do 330Knots at FL 38, so once again congratulations for the
job, eric thank to you for the commercial side you have ever been a great
help without with this sales would be impossible even when we do not put
any gain on this and other new prop sales you have ever been there
understanding our "third world" requirements to be able complete a deal,
thanks a lot and definetely this encourage us to keep on working to sale
more oustanding performers MTpropellers.

Can't say enough good things about your 5 blade props on my Merlin IIB.
What an all aspect improvement! I look forward to seeing the final performance numbers from Joseph's analysis but subjective reduction in vibration and interior noise is significant. I am very happy with their quality and appearance as well......

Joseph, Doug Turner and the entire DeLand crew were very courteous, professional, and pleasurable to work with during our time there.
I am very happy with my MT props installation. Thanks again and looking
forward to hearing more from you soon on the certification process.

The electric MTV-17-C/183-17f gives my 105 hp Piper the same performance
like a 150 hp Super Cup with a fixed pitch prop. Flying up to 16000 ft is
no problem and cruising on the other hand with 3 GPH at 65 kts works also
fine. Thanks to the MT-Propeller Team for this great propeller ...........

...The smoothness is perfect at 2400 and 2700 and only a slight shake at 2500 and 2600, not even enough to worry about...I also saw 3000 fpm climb at full power from 5K to 8K. The most I have seen, with half fuel and one person.
I also leveled at 12K and did all the rpm's and then set up my normal cruise power 65% or 30/2400 and my IAS was exactly 6 kts faster, just like Martin said it would be. I showed 192 KIAS for a TAS of 233 on 24 gph, for what it's worth.
And after the flight I took these pictures to show that the super paint job survived
without a mark...
Many Thanks,
Jim Hergert

the airplane is in service fot the UN in Africa since mid July 2007.
... Got some good numbers going and coming, within a knot or two and 20 rpm of my old prop, which was the absolute best prop I have ever flown. So, in a word, I love it! I don't fear rain anymore and it looks cool...attached is a pic....see ya!
