Yes indeed!

The R1300 never sounds "Right" to me, I remember hearing them in T28's at air shows....I am always thinking....Dead Mag? - LOL!

@@misters2837 I've got about 1200 hours in the T-28B and C as a test and cross country flight mech/E2P in VT-2, VT-6 and NARF Pensacola for 3 years in the late 60s. After volunteering with a group that rebuilt an 1820-86A for a resurrected B back in 2014, I got a ride in the finished bird with a retired navy pilot who had been an instructor at Whiting Field when I was there. I noticed a big difference in exhaust sound from what I remembered from the 60s - that smooth, almost deafening note at 52inHg was missing - still had good power though. I assume it came from the differences in new and old fuels - green 100/130 alkylate vs the original 1940s era leaded 115/140 purple that went away about 30 years ago and has only recently made a comeback. When supercharger HIGH was selected at 15,000 feet while climbing at a pretty good rate, it didn't give the same kick in the pants that I remembered, either. The old bird (whose every switch, lever, and gauge I can still visualize in total darkness) remains an impressive machine and needs no excuses in the presence of it's elder warbird brothers....

@@misters2837 Yes, the 9 cylinder radial engines with their 5/4 exhaust always sounded like they were missing on a cylinder. Only the high power runup rpm test knows for sure! But, the T-28Bs and T-28Cs that I flew in 1971 in VT-6 were equipped with the R-1820. The S-2C, C-1A, and Hu-16D were also equipped with the R-1820. Never heard of a R-1300. That must be the 7 cylinder engine in the T-28A that the Air Force flew.

@DavidParker-cf2km That Makes Sense NONE of them sound "RIGHT" the 5/4 9cyl B/C or the 7cyl A-Model! - They wanted you to always think there was something wrong with it! - They Sound like a V8 missing on 2 cylinders about 1 cylinder apart....so like Bang Bang Miss Bang Miss Bang Bang Bang.....I know, cuz I had a car that ran like that when I bought it! (Needed Tune Up!)

@donallen, thank you for your service during the not so cold Cold War. We were at or near SAC bases which had the B-36, C-124, KC-97 and KB-50. I remember that sound at takeoff, the drone when they flew high above us and the dishes rattling in the cabinets.

They were built about 5 miles from me in the East Hartford, CT "Headquarters" plant. What a campus they have/had over there. 600 acres I think, with their own airfield and buildings that go on and on. At the peak in the 80's that plant alone employed 60,000 people! (And they had several plants around the state!) Now, it's a sorry shadow of itself. Maybe 3500 people there, and only one other plant still going with a skeleton crew. Don't forget the SR71 Blackbird would not be what it was/is without Pratt solving the problem and coming up with a turbo/ram jet hybrid engine! Pure genius! Official speed of Mach 3.2 but reports from pilots getting close to 4 with plenty of throttle left, at 80,000+ feet! It was the fuselage that couldn't handle the heat from the airspeed, not the engines holding it back! I listened to one story from pilot Brian Shule (sp?) who had to outrun a SAM shot at him (Process that for a second. LOL ) and throttled up, limits be damned...he said he tried to touch the canopy afterwards and couldn't because it was too hot...with gloves on!!

I bet he got a strongly worded letter from the neighborhood association.....

Facts as stated above! (Love the Mechanical Pencil...)

Not only that, but they were designed without the help of any computer.

@@stirlingschmidt6325 You got that buddy. I talk about slide rules, vernier calipers and architect triangles and kids look at me like I'm from another world...and I am

Kids these days, eh? Quit your bullshit. As a "kid" that is quite mechanically and a bit electronically inclined I find your mindset quite rude. Kids that know about mechanical stuff haven't gone anywhere, you just have to get out of the social media bubble that is mostly populated by mechanically illiterate people. Besides, being mechanically illiterate is not a bad thing, everyone has their own hobbies and likes, and without all kinds of expertise the world wouldn't work.

@@netts2315 Well there Mr. Netts, the only thing I said wrong was that it should have been stated "some kids" (I just edited it) . I know a good amount of kids, like you, who are mechanically inclined and technically/electronically astute. Your comment about the "social media bubble ...populated by mechanically illiterate people" is spot on. I do watch a number of gifted kids working on complex stuff. Admittedly, I can do a very limited amount the higher tech cross-over of mechanical and computerized engineering. I had to learn computer mech/tech when I was in my mid-50s and am amazed how much I've learned to appreciate it over the last 20 years. Hopefully, "as a kid", you'll enjoy learning old and new things when you're in your 70s. Respectfully, Theo.

Значит мне не одному это казалось

There good. But in my opinion nothing beats the sound of the B25's. Those R-2600's are a deafening symphony!

It’s even better from the back seat of a P-51 Mustang, I used to maintain one, test flights were the best!

@@marcwesley8513 you lucky bugger, i would love to experience a flight in one.

@@marcwesley8513 This I can agree with. We keep one in working order at the local airfield here.

Many years ago in Sydney,Aust I took my 8 & 6yr old daughters to an airshow at Bankstown airport specifically to hear a Spitfire flypast.They're in their 40s' now but still remember it. My duty as a father was done that day !

Best Aircraft Engines even today piston or Jet Rolls-Royce !

Imagine your house being downwind of that cloud of oil vapor coming the exhaust!

Griffons

My neighbors' kids make more noise than this.

I'd be mad if he didn't let me know when he was going to run it, so I could watch.

Reply: Its sound of the Freedom!

@@juhajuntunen2557 Nah... It's the sound of slavery to anyone actually paying attention.

I'd run right over there and....ask if he needs any help. LOL

No counterrunning propellers on spitfires

@@andrslnks4804 No. I think the Sea Fury had contra rotating props, the Griffon in the model Mk 24 Spitfire I have built did not.

You haven't got a clue what you are talking about. The first production Griffon powered Spitfire was the Mk XII. Quickly followed by the Mk XIV. No Sea Fury had counter rotating propellers.. There were Spitfires with counter rotating props, The Seafire Mk 47 is one for example. Typical internet experts, clueless..

@@zero1zero184 Go for it mate.

I always thought and saw old ads in magazines that the P-51 had Allison engines in them. They are a similar design to the RR, were they licensed to build them under the Allison name or what was the deal?

Only the best in safety equipment 👍😎✊

@@steven.h0629 😆😆😆. Safety 3rd. 🤪

"Roll-Royce 12 cylinder radial engine on it" No such animal.

@@wagonmaster1974 he was being sarcastic. 😀 RR never built a radial engine. No such thing as an even cyl radial engine. 🤪

I am a far left wing guy, and I love this too, without a hint of shame.

Me too😎

Maybe because they all rotate counterclockwise, so a "stroke out" of joy?

@@asmundukkelberg8741 you know they were burning fossil fuels right?

@@asmundukkelberg8741maybe the designers of these engines were racisss too 😮

Heh.

Like your ass

Rotating the cylinders helped to cool them when they were on the ground hence they were able to get some good power from it without the engine overheating. Manufacturing air cooled cylinders with effective and efficient cooling fins was still quite a challenge at this time, a side effect as you say was the gyro effect on take off and in turns when flying. The other side efdect was that they were 2 strokes that used castor oil for lubrication, after flying a couple of hours ingesting those fumes you were cleaned in your bowels when you landed!

Thank you! Cheers!

Glad you enjoyed it

Yep - I watched it from start to finish Fascinating !

I concur with your sentiments gentlemen

Thank you! Cheers!

Connie's to me were one sexy airplane

@@jayjones6904 Yes "Connie" was a female name that applied when we enjoyed the very curvaceous, sexy profile of her slender "fuselage", those long lifting airfoils of her "wings" and wow did she have big "engines"

Glad you like it!

Thank you! Cheers!

That's why the tips of the blades are painted yellow or have white stripes or spirals on the central spinner. Hence the phrase "clear prop" before starting. 😂

@@Stevie-P123 Can’t say I’m impressed by that minimal measure. A demarcated “do not enter” zone would be my chosen action.

@@josephinebennington7247 open propellers have been used on aircraft for as long as they've been around , I think the consequences of walking into a spinning prop are pretty obvious. These public displays are usually cordoned off to a safe distance. Aircraft engineers have to use "common sense" when working on a running engine. It used to be a "thing" once apon a time. 😉

@@Stevie-P123 Murphy’s law is the obvious response. These are display mounts where non-engineers with no common sense can be found. I’m an amateur engineer with plenty of common sense and I wouldn’t fail to demarcate where things get dangerous for the sake of my own head. I’ll stay this side of my screen.

@@josephinebennington7247 arr a fellow engineer , I've been building proped aircraft engines for the best part of 30 years and standing next to these things when they're running is enough to put the fear of God into you , and I'm not even religious. 😆 All the best to you Josephine. 👍

Correct. R2800-79 or -81. One had Bendix mags and the other GE magnetos. I flew the A26 for years fighting fire with both dash numbers. A great engine. But it will quit cold if it doesn't have air, fuel or the master rod breaks. I had all three happen. Radials can let you down. The only people say a radial will never let you down never put enough hours in behind them.

Great movie

Not to mention completely worthless.
