did not hear him say 'CLEAR " before the start of the prop....

Stupid decision... Heavy engine in aircraft

2022. But the music is old!

What year did they make this video? 80s?

Great informative video thanx

Actually, Cessna stopped production of the 172 in 1986. Production resumed in Independence, Ks. in 1996 and continues there to this day. They also produced the 182 and 206 there.

To cool

Canada’s producing a V 12 Beaver airplane looks pretty nice

I saw a video of a cropduster (air tractor) severely modified to run a V12 diesel TRUCK engine. Running on Jet A, it was a real showpony, and could do a ballistic climb :)

That uphill on the French bike was a damn good laugh. I needed that!

It would be cool to put Snow watermeth injection on it.

Great video for my deaf left ear

You need a better microphone my left ear got a workout.

The 6 popper is not less reliable that's a crazy statement.

Diesel engine isnt suitable for aircrafts

The 172S was not considered the XP. That title belongs to the R172K. It was literally marked as Hawk XP. It came from the factory with a 210hp motor derated to 195hp

What is Jet A1? Isn’t that a kerosene? Why are they not burning diesel in it if it’s a diesel engine?

Turbo diesels..it’s about time…

Do you think in the near future, low-end to mid-end bicycles like MTB, road, touring, etc will be equipped with electronic groupsets?

Is the electronic groupset/shifter the new standard for Tour De France road bikes?

People still thinks that 3x7/9 is the true geared bike and 1x12 system are just a hype, nonsense, 1x12 is the real deal 😂😂😂

Who invented the front derailleur?

I wish Cessna was still making "affordable" new aircraft...

Actually, Cessna began production of the 172 in Independence, Ks. in '96

Just to be accurate it is "injectors instead of spark plugs" the glow plugs are more analogous to a choke for cold starting. Rudolf Diesel Invented timed injection. He did not invent high compression...

Did the first 20-25 hours of my PPL in Red Birds 101-103 ...I didn't know how amazing that fuel burn was until started flying standard 172's.

Just flew one of them at KJWN. Easy run-up, very quiet and smooth.

some of the mercedes diesels can make a lot of power when modified. Wonder if they could get the om606 3.0 6 cylinder turbo diesel to work with it.

Not enough climb rate. Need more power.

Built for fuel savings. If you can afford a plane, you can probably afford the fuel.

5 speed suntour is where I came in, now on 12 speed Campagnolo.

Just a little addition to fill in the gaps. In the 1950s was the Oscar Egg, Osgear with a spring loaded chain roller running on the bottom chain line taking up the slack over 3 sprockets. In the 1960s we were blessed in the U K with the Benelux horizontal spring action using down tube control lever and manual lever on seat post to change 2 front gears, turn it left/ right to select. Ray Booty in 1950s set national 100 mile record 3 hrs 32 mins using heavy Sturmy Archer 3 speed close ratio gear ! Then in the 60s came the 3/32 inch width lighter flexible chain we use today. Thus ending the racing on fixed gear for time trials as was then established practice in the U K . It became possible to to race 6 speed and more, breaking away from the limiting 5 speed of the 1/8 inch standard chain width previously only available. Chain pitch is still universally and W- Wide 1/2 imperial inch. The rest is history, you all are experiencing now. Thank you for a fascinating video particularly the back pedalling gear change of the French design ! Who else ?

I need to purchase me a Brompton

Wow this video is amazing lol good job

There’s so many hilariously stupid designs in the past… would love to see a much longer video on those.

Oh, and this doesn't dump lead from the aviation gasoline into the air, right?

He is like Michael Jackson of cycles

Thank you.

The ferrari comparison is absolute nonsense, specially considering it's a double clutch transmission, not even motorcycles use those.

It always struck me as odd that Japan, with no history of cycling to speak of, is the world leader in derailleur gearing. Proves the industrious nature of the Japanese.

It was always said that Shimano wears out, Campagnolo wears in.

The only problem with the Retro Direct is that if you pedal backwards for any distance, the pedals will unscrew and fall off - ! 😅 An odd oversight for a great idea.

Moonwalking uphill had me creasing 😂

Bike moonwalk

my flight school air harmony flies about 6 of these and I love them especially the throttle. Its a little bit different in the normal 172 layout but it flies so smooth, would def reccomend this aircraft!

If I could offer some feedback on this old video: Its absolutely fantastic, I mean, genuinely great video. The only part I could suggest you improve are the thumbnail and title. They arent appealing enough and "A history of gears" doesnt really convey what the content of the video will be. For better of for worse, good and appealing thumbnails are the mark of a successfull youtube video.

Thank you so much for the awesome video! I'm about to starting training to get my PPL in Washington, and they offer the 162 and the 172 as options. The 172 is far more expensive, so I don't want to choose that, but the 162 is such a rare plane with some people claiming it's not a good plane that I have some concerns about flying it. This video made me feel a lot better about it. Thank you :)

Reminds me of my 63 VW Bug….

I recently had the chance to fly the Robin DR401 with this CD-155engine. This plane is wooden and therefore lighter than the C172, so the payload penalty is insignificant. The engine was fantastic. Efficient, the constant speed prop gives lots of power. I believe that now where the engine belongs to Continental, it finally gets the marketing power it deserves.

If such good performance why not good on long distance flying ?? Just don’t make since !! What you hiding??
