Great video guys! Always nice to see a company as dedicated to safety and testing as this one. A real plus to see a company that keeps highly educated and experienced employees working!
It's wonderful to see there's still American companies that has not been sold to an foreign company. Not to mention building an outstanding product. Bravo
Great video flitetest. Being an FAA A&P Tech (helicopters), I really appreciated the connection of today's hobbyist to real world employment. We need more young people to take an interest in the field. Keep up the great videos!
More videos like these please, I love your hobby craft and all at flight test, but the educational side of it, and showing how planes are constructed currently is awesome! thanks
Awesome episode guys! What we really need are controllable pitch props for R/C models, and I'm not referring to the ones for 3-d flying. For racers and hotliners, we have to use extremely high pitch to get top speed, but the result is a prop that is stalled out until you reach 50-60 mph, making launches/takeoffs extremely difficult.
For those wondering what the black light stuff is, its another form of NDI. Non Destructive Inspection. This form uses a dye penetrant that show flaws under black light. There are other forms that use eddy current, or electricity, kind of like a micro radar to find cracks, and also x-ray to inspect composite materials.
The aviation club here in Hong Kong actually had a sensenich prop shipped to us and because it was so massive we had to pick it up from a local UPS place. Apparently the guys there are like, "Why the hell do you need a propeller...." They have no idea where we came from.
australia post would just chuck it over the fence and keep driving, or stop on the street and leave a 'sorry we missed you' card without even knocking on your door
Correction* they change oil pressure inside the hub not the prop as you stated. Constant speed is actually a very old technology dating back to pre war aviation and besides advanced materials they haven't essentially changed much since then. Hartzell have always been one of my favorite manufacturers of this often overlooked facet of aviation, it's Hartzell that brought me home so many times. I hand carved my own wooden prop when I rebuilt my canard weight-shift Eagle ultralight when I was 16 and man did I struggle, the slightest asymmetry or imbalance causes such a severe chain reaction of problems that can ultimately bring an aircraft down (the United Express Embraer that had a full prop detach comes immediately to mind) so it is a very precise science we really should respect more, great that you covered the art in this informative video.
Excellent video. I've done a fair bit of flying on Hartzell propellers and found this very interesting. I'd love to see any extra footage you got, especially of the pitch change mechanism.
Wow, fantastic episode! Very well done, thanks for sharing this with us! I used to do Dye Penetrant inspection when I was in the Navy, its a pretty cool and relatively inexpensive process, was cool to see the failed part!
Hat tip to the guys at FliteTest, the folks at Hartzell Propellers and to anyone else who was involved with the presentation of a quality, informative and relatively short video concerning a topic that is just one possible yet necessary component towards powered flight....at least anyways on this planet!
Thank you a wonderful video, my prayers are with you at FliteTest and all employees , folks like you make a real company great a very wonderful thing and a good place to work !! BLESSED
I like this kind of aviation content. It is interesting and informative. It is great to see one more facet of how OHIO was and still is the birthplace of aviation.
I understand the overhaul disappointment. I just sent my Hartzel constant speed prop to Sensenich (becasue theyre closer to my home airport) when it was torn down the hub was found out of tolerances and to be scraped.
Really great and I like the general aviation content. Maybe you could do something on CATTO props? I own of one of their props and his story is really cool. They are really popular with the experimental crowd.
It’s more important to know how to make something then to know how it works. Also I love how the comments straight up jumped to compliment a company for not replacing workers with robots.. like they’re going to let you know that lol... -Side note. We are not any the wiser on how props are made after this video. Retitle it “how props are polished tested and packaged” there was 0 manufacturing in this video.
I have an important question. On Lockheed Martin's F-35 jet they have vertical take off and landing. How can the rotor/propeller stabilizer/holder stay in the middle of the whole that's inserted on the jet to make the blade transparent from above and below?
JetMechMA I have an image but it’s a project that I’m trying to do that could help millions of people. If you’re interested I’d like your help. If not it’s fine.
That day when you've been a fan of the channel for so long that you can remember when they just did one video a week, and now that they do videos 5 days a week, sometimes more, you're disappointed because you've seen them all.
I'm going to University in September and want to set up a society for learning about drones and the different type of planes as well as make them and fly them. Are there any ideas or advice you could give to start me off ?
RC flying rc lead to my fascination with soaring. I know that you did a video on full scale soaring but I would like to see something on glider racing. It's such a dynamic sport but it's popularity among spectators suffers because of among other things an understanding about all that is involved.
One and done, or done and one? It sounds like a quality initative to check and document at every step that the operation was done correctly. "One and done", has a less favorable connotation than the latter.
I've always had the idea that propeller manufacturers should design their propellors with winglets on the tips. It would increase efficiency, I would think.
Daniel Skoog might work with a composite or some other light strong material. I think with metal the extra weight would outweigh the savings. Would also have to figure out the balancing. But it's a good idea. Might see them in the future as tech advances
Tallishyeti27 Yea it would be easiest with materials like fiberglass or carbon fiber. The importance is to eliminate the vortex at the end of the propeller blade just like the one at the end of the wing, reducing drag. It could be easier to do with a RC plane propellor. Just molded plastic.
It does reduce the induced drag, but it adds surface area right at the tip where it's moving fastest, so then that adds friction drag and it's more or less a wash. But apparently if the winglets are angled backward, it does make the propeller quieter. I really want to build myself an electric paramotor with one.
Been by Piqua 100 times, but never stopped in... Too bad those constant speed props are so dang expensive! There are several RC ones too which are cool...
I wanted to see the pitch change on them. has to be sweet to feel inside the plane. ive only seen one variable pitch quad. ran on a belt drive system with one motor. can't remember the name of it. I guess its not a reliable racing setup or more work would go into designing one....:)

soy tecnico de helices y este programa es muy interesante asi aprendemos mas😊😊
As a certified airframe and powerplant technician I found this video fascinating. I also am certified for NDT inspection. Neat stuff!
Great video guys! Always nice to see a company as dedicated to safety and testing as this one. A real plus to see a company that keeps highly educated and experienced employees working!
I'm a pilot and this was really cool. I enjoy all of your videos.
It's wonderful to see there's still American companies that has not been sold to an foreign company. Not to mention building an outstanding product. Bravo
M Rose I wouldn't trust my prop if it was made out of A Chinese alloy
"Built on Honor". Love it. Proud to own a Hartzell Prop!
Great video flitetest. Being an FAA A&P Tech (helicopters), I really appreciated the connection of today's hobbyist to real world employment. We need more young people to take an interest in the field. Keep up the great videos!
I enjoyed the Hartzell tour. Nice job and professionally done as well. Thanks....Ian Bell Honeywell flight test
love it. I have huge Hartzell props on their hub right above my desk, all polished out.
More videos like these please, I love your hobby craft and all at flight test, but the educational side of it, and showing how planes are constructed currently is awesome! thanks
Love seeing American manufacturing doing what we do best. Working hard, making money and supporting families!

Thanks!
You guys do love aviation.
Thanks for the inspiration and keep on trucking!

ok ok.
Is there a diferrence between ndi and ndt?

Awesome video, super glad to see all this awesome new GA content. Thanks for everything you all do!
SO exited as soon as I see a new Flite Test Video. Very Interesting! Keep it up!
great video, thanks for sharing and thanks to Hartzell for allowing "us" access to see what they do.

"How It's Made" FliteTest style.... I enjoy these types of videos. Thanks for making it.

Excellent video!!
love these types of vids
Love this guys!. Love planes. We all dream of the big stuff.
Great video about a great company.
Great video, I'd love for it to be longer!
Wow I never knew that it was this complex to make a propeller thanks for teaching me how they make propellers 👍🏻
Thanks for the great video, guys. There's so many interesting facets to aviation. Awesome to see a company that values it's employees as well!
Great video! What an interesting topic for general aviation. But thank God R/C parts are cheaper.
Well, some of them are cheaper. ;)
I want to see more of these type of vids from Flitest good job thanks to Hartzell for allowing as a peak into how they're made
WOW WHAT A GREAT VIDEO. THANKS FOR TAKING THE TIME TO SHOOT IT. NOTHING LIKE GOOD OLD AMERICAN, GRADE (A) PRODUCTS. GREAT JOB !!!!
Cool tour.
Awesome video. I'm just left with one nagging question. What kind of tape do they use to balance their blades?
The glare on his eyes when talking about this is amazing. That's how you look if you are passionate about something.
Thank you for the great content!
Thank you a wonderful video, my prayers are with you at FliteTest and all employees , folks like you make a real company great a very wonderful thing and a good place to work !! BLESSED
flitetest needs to do a how it's made series!
Such a polite young man.
Great Vid! Thumbs Up!
Flite tests version of How Its Made!
Yup. But way better.
Daniel harman Only hire it's made us over: (
What was that at 1:00 🤣🤣 old technology was very dangerous.
This was very knowledgeable video thanks for posting this type of video also
I like this kind of aviation content. It is interesting and informative. It is great to see one more facet of how OHIO was and still is the birthplace of aviation.
That is very cool to see.
I am impressed.
Really cool stuff, thanks!
Great Information **Kudos**
Much affirmative goin' on with this blade-slingin' tour!
Thank you for sharing this video, I want more...😀👍
Awesome video :)
Interesting stuff!!
awesome, awesome, and awesome.
Very cool! thanks
I Used to make these in Lego with pneumatic parts. Superb fun!
Love my Hartzell. And they sent me a 100th birthday t-shirt! :)
Great video. Where did you get the wood propeller at.
I understand the overhaul disappointment. I just sent my Hartzel constant speed prop to Sensenich (becasue theyre closer to my home airport) when it was torn down the hub was found out of tolerances and to be scraped.
Amazing! Now I know where to get a propeller for my room.
Good video
Really great and I like the general aviation content. Maybe you could do something on CATTO props? I own of one of their props and his story is really cool. They are really popular with the experimental crowd.
Yes! I was researching exactly that a week ago. thank you :)
Do those props automatically change flight characteristics or manually? Seems like a super awesome idea.
There are constant speed propellers, and variable speed propellers. Constant speed is automatic while variable is manual.
Torque556 thanks!
This might seem small, but good use of PPE. Safety first.
What materials do they use for propellers? Steel or aluminum?
Ive been at the RAF museum in London, and the most interesting thing there, were how old wooden propellers are made.
It’s more important to know how to make something then to know how it works.
Also I love how the comments straight up jumped to compliment a company for not replacing workers with robots.. like they’re going to let you know that lol...

Pretty cool. What kind of price are these propellers?
Their normal propellers start at about $5,000usd each and peak at about $25,000usd each.

hey josh what is that orange airplane on the wall behind you?
Can you guys do a video on how helicopter blades are made? The actual blades. Thanks.
TBM? Nice plane!
So cool!!!!!!!!!!
Is that a Culver prop from the Pete?
Been making my own foam props, . why are they not holding up?

Daniel Skoog hartzel already makes one. It's called a Q-Tip Propeller.
It does reduce the induced drag, but it adds surface area right at the tip where it's moving fastest, so then that adds friction drag and it's more or less a wash. But apparently if the winglets are angled backward, it does make the propeller quieter. I really want to build myself an electric paramotor with one.

What language is that? Persian? Google wasn't even able to translate it :)
no, it's kurdish language

😀😀😊😊😉😉
baul were are you frome 😊
Been by Piqua 100 times, but never stopped in... Too bad those constant speed props are so dang expensive! There are several RC ones too which are cool...
cool info
hey flite test do a flite test south that would be awesome and can you do a full review on the forge 3d printer.
2:22 Imagine doing all that complex machine work by hand ! Like they did in WW2
pretty cool
I WANT TO WORK THERE!!!!
would love to work there as an environmental scientist one day, I even have my private license working on ifr now
demo very good
I wanted to see the pitch change on them. has to be sweet to feel inside the plane. ive only seen one variable pitch quad. ran on a belt drive system with one motor. can't remember the name of it. I guess its not a reliable racing setup or more work would go into designing one....:)
'
what kind of materials are the best on the airplanes...
aluminum or fiberglass or plastic or wood
Do u have video repaint prop?
I challenge y'all to biuld a steerman pt-17 and fly it. Also when are the new scratch builds coming?
That's so cool that they have a hanger for their employee's aircraft.
Is that a TBM?
The guy in the factory what was the things he wore on the side of his glasses. Like things blocking his FOV
They are protective side guards to make his regular glasses safety glasses :)
What's the song in the beginning
