I was part of the team that originally built precious metal in 1987. The only thing "original P-51" on the whole airframe is the tail, from the rudder on back. To get the griffon motor to fit, the firewall was moved rearward by almost 2 feet to keep the airframe within the CG envelope. At one point in time, one of the original designers of the P-51 consulted with us during the build. The project manager for the build is still restoring and maintaining P-51s today.
Aside from the beauty and performance o the aircraft, i am most impressed by the photography. It's rare that this type of recording can keep the subject in frame and focused 100% of the time. This is exceptional.
@cannonfodder6299 lol yea. The P-51 didn't even come close to having concepts in mind that determined area rule, all-moving tails, ect. One thing it did try very hard in and did pretty well for its day was more manufacturing focused - the goal of trying to keep Laminar flow around the aircraft, namely the wings, in an effort to reduce parasitic drag. For an aircraft that was produced as cheaply as it was, as fast as it was and as much as it was, to even have manufacturing results that had good characteristics to try and maintain laminar flow over the wings was impressive.

@Mark Grudt the original mustang had a Packard v 12 and the performance was OK.. tben rolls Royce sent them a merlin..and the p 51 became a true fighter..now its got a grown up engine.. supposedly there were 3 of these prototypes in 1945
Nah, not gone. They’ve said they’re relocating to a new airfield, but they have no intentions to stop the racing any time soon. Can’t say I blame ‘em for wanting a change of scenery. Roswell is a gorgeous area with an extensive aerospace history.
More crazy is that the RAF had a twin engine bomber (De Havilland Mosquito Mk B35 apparently, with Merlin 77 engines) in 1942 that achieved 437 mph with and could cruise faster than a P51 all the way to Berlin and back. Pity there's none in airworthy condition or any P38 Lightnings to compete if there is a class ?
Reminds me of the old Red Baron Flying Service P-51 that crashed with Steve Hinton at the controls, in 1979 at Reno. When we saw the fireball we figured he was a dead man. But he survived with a broken back, leg and ankle. they said his cockpit was almost a mile from the main wreckage.
With the counter rotating props and that big RR Griffon engine... cranked up my speakers and the sweet sound of forced induction V12 made me cry tears of joy!! Love it... Bucket list trip is the Air Races to see these magnificent beasts in action!
Man, I love the narrow sleek canopy it really works with the lines of a Mustang. I have an unrelenting passion for prop planes, there is nothing like a low and fast prop buzzing past. That sound is like music to me.
I love this plane because it gives us a look at the last Spitfire that never was. In 1945 Supermarine developed a Spitfire with the Mustang lamina flow wing and a 2400hp Griffin engine with contra rotating props. Because it no longer had the iconic elliptical wing they renamed it the Supermarine Spiteful, only 17 were built and it never saw service as the jet age had arrived. However the power plant was used in the Shackleton bomber, I assume that is where this planes engine came from. So now we have an idea of how the ultimate Spitfire would have performed.
@@devinthierault @Josh Jack You are both correct, all the Spitefuls built had the Sea Fury 5 blade prop but material I have read tells that this was an interim development stage and the intent was to use the still under development contra prop system.
Fantastic, very nice color of the fuselage of the Precious Metul plane! Great takeoff then laps or tracks, maneuvering speed super video !! your demonstration was awesome, 440,383 MPH and second pass 438,032 MPH, congratulations the pilote to all who participated in this video. Thank you.
I have seen this video numerous times now. And the sound when this plane passes by gives me goosebumps - absolutely spectacular. Thank you for keeping these mashines going :-)
The back propeller has smaller diameter than the front one has. The blades seems to be a Rotol type, but it is different. The contra porp Griffon engined Spitfire has same prop diameters, cutted blade tips, the Shackleton also has similar contra-rotating props, so this one could be camde from the FR-47 Seafire.
kolbola This particular engine was originally from a Shackleton, then it went to the Miss Budweiser sponsored hydroplane racing team from the 80’s. The prop was a stock unit that the team had custom cut to have the scalloped tips.
***** Precious Metal uses a larger-displacement Rolls Griffon engine, like the later marques of the Spitfire. If I remember correctly, the engine and contrarotating props are from a postwar British airliner.
BlackBunik These particular blades came from an Avro Shackleton bomber and then were modified by the team, but you are correct the later Mk. Spitfires did use this setup, the Mk.47 being one of them, Supernarine also used this setup on one of their last piston fighters as well (Supermarine Seafang).
Wow! What a beautiful airplane and the performance is amazing. And also, Those 2 propellers spinning real fast looks kind of intimidating to me and the sound of the plane starting up also intimidating.
listen to her purr....best music I've heard on a video in a while. I flew my P51 so much I finally wore it out. So a friend of mine gave me his P51 - said he was not flying it much anymore....had moved on to jets. No, not the full scale.....an RC plane.
From my understanding, gyroscopic procession and P-factor would still affect it, just torque would not be as much of an issue. Still needs more right rudder.
@@guntherachterhof4876 Oh yeah definitely. You can't full throttle a (stock) P-51 on take off from the go or you'd go off the runway. (Generally speaking we always ease power on, because more air speed means better rudder authority)
Yep, I thought so. No matter what a bunch of guys do, there's always this one guy. The guy that takes everything to a new level! That guy! In this bunch, this is that guy. Jezzz counter rotating prop on a P-51! Yeah thanks. Damn nice work.
Beautiful ,absolutely beautiful. Love the counter rotating props so no torque problems. I always wondered how the p51d would look if developed further. ( There was a design in the 80's that used small jets to boost speed but it was dropped) .p51 d has always been my " pin up" of ww2 fighters. Poetry in motion. Best regards.
I was at the 1999 Air races when Miss Ashley II crashed on Saturday. She was a beautiful aircraft which was highly modified with Contra-rotating props and a Griffon engine. She had learjet wings. Cause of crash was the rear stabilizer (somewhat similar to the Ghost crash) came off and torque tore off the wings and the fuselage landed on an unoccupied Winnebago in an eastern community. Pilot never stood a chance.
Even radically modified, the p-51 is the most beautiful airplane ever made. Side note: did the counter rotating props increase the top speed at low altitude? And were they variable pitch?
The Tu-95 Bear uses counter rotating props and I didn't know why that plane used CR props until I asked around which makes sense now....CR props are cool to see
Is a very fine piece of technology with the modifications involved in the desing, but i prefer an original P-51D fighter plane, even today. She was a fantastic aircraft, with the Packard-Merlin engine and her frame line original, sorry my bad english, and greetings from Santa Rosa, La Pampa, Argentina.
Counter rotating props also help to reduce what is known as the "P" effect as well when flying. That is the technical term to when a prop produces so much torque that it will make turning, taxing and taking off with the aircraft harder on one side than the other. As developers started to produce engines that produced more torque, the "P" effect really started to become a hindrance. So much so that you either needed special training in how to counter this effect, or something like a counter-rotating prop. Look at the Russian T-95 "Bear" Extremely powerful turboprops, with counter rotating propellers
Trying to come out of a high altitude power dive with that monster would be 'interesting'. A beautiful aircraft. Does it have an original Rolls-Royce engine from the period? Note: I read down further and got the answer to the engine question. Until they were fitted with all those horses, it's amazing how the U.S. thought it had limited use. Refitted with the RR, and with the addition of extra tanks for further range, it became the perfect escort fighter for long range bombing runs. One of the top fighters of the war.
If this thing can do 700kph on the deck, what can it do at Altitude? they had planes with similar power doing 750Kph+ ready for war at alt, this thing is surely lighter due to weapons and radio gear removal/modernisation and more aerodynamic due to cockpit changes?
All racing is pushing the envelope, what is/are the limiting factor(s) here? Is it turning the plane as fast as you can without it breaking? Is it g-force limit? Is it having the most powerful engine? Best aerodynamics?
Damn! Contra-rotating propellers? I have to wonder, aside from maintenance issues, how this would have affected the original P--51s performance in wartime use? It must be a wonderful feeling not to have to worry about how all that torque would affect your flight dynamics.
They built one at Wright Paterson AFB during WWII. Just one... they had insurmountable issues with the prop gearbox. Technology was not quite there yet. My uncle was an engineer there at the time.
@@richardoakley8800, You nailed the primary reason the P-51 became the legendary fighter it was. The Allison V1710 engine that equipped the P-40 was not adequate for high-altitude work where the bombers they were supposed to escort flew. When one of the test pilots for Rolls Royce strongly suggested that their Merlin engines would be much superior, he was right. It didn't take long for everyone else to come around to his point of view. The Merlin was a heavier engine than the V1710. So to maintain the proper center-of-gravity, North American engineers added a large additional fuel tank behind the pilot, greatly increasing the Mustang's range on internal fuel. Throw on some drop-tanks and the Allies found the long-range fighter they had been looking for! The Roll Royce Merlin was, as Jay Leno put it in his video on the Merlin (ua-cam.com/video/GYcKdK7hmEo/v-deo.html), "The engine that won World War II."
I'm just a blues guitar player who likes to get me breath taken away by the baddest ass racing plane Reno's ever seen. Thanx for a perfectly done video. ...and cheers
With the introduction of the Griffon, R-R changed the firing order from that used in the Merlin. Quote from Wiki: "Merlin firing order: 1A, 6B, 4A, 3B, 2A, 5B, 6A, 1B, 3A, 4B, 5A, 2B ('A' being the right bank as viewed from the rear of the engine) Griffon firing order: 1A, 4B, 3A, 2B, 5A, 1B, 6A, 3B, 4A, 5B, 2A, 6B (changed from the Merlin to reduce stress on the crankshaft)" The Merlin has a musical hum that gives you goosebumps and makes your hair stand on end.. IMHO the Griffon doesn't sound quite as smooth.
I think the Griffon has the same firing order as the Allison. The Merlin sounds more aggressive to me, like it's got radical cams out of a hot rod. But there's no replacement for displacement, and 2240 cubes beats 1650 any day of the week.
I was at the races that year. So it wasn't the fastest, but god damn it was one of the best sounding!Just another reason I love living a few miles from the Stead airport, and in such a quiet neighborhood. Except of course in the couple weeks around race time. I don't think anyone minds the extra noise.
There was a third Griffon powered racer at Reno in the past that no one has mentioned - Miss Ashley II. Built from the ground up as a racer and not from a P51 airframe, although it looked like a P51. Lear Jet wings and horizontal tail, Cessna main gears. It was a beautiful racer, and unfortunately, never got to see its true potential, because it broke up during a race at Reno in 1999, apparently due to tail flutter.
Contra-rotating propellers were not used on WW.II combat P-51 Mustangs. "Precious Metal" is a special, experimental category, air racer modification of the P-51,
Team pulled the Merlin out, moved the firewall back some 2ft to make room for the Griffon engine, which I understand came from an Avro Shackleton bomber. Certainly a fine looking aircraft, but it should have been left original, imho!!
Interesting. The Italian seaplane with floats, the Macchi Castoldi MC72 set a record of 440 in the 30's. Had contra rotating props. But that was in a straight line. Wonder how much speed it costs to go in a circuit. Anyone know?
Oh my, what a sound that Griffon makes, and beautiful propellers too. In a Shackleton it was horrendous, but as a single... Fantastic. Now, anyone out there have a Napier Sabre engine for a P51?

The Allison V1710 engine that equipped the P-40 was not adequate for high-altitude work where the bombers they were supposed to escort flew. When one of the test pilots for Rolls Royce strongly suggested that their Merlin engines would be much superior, he was right. It didn't take long for everyone else to come around to his point of view. The Merlin was a heavier engine than the V1710. So to maintain the proper center-of-gravity, North American engineers added a large additional fuel tank behind the pilot, greatly increasing the Mustang's range on internal fuel. Throw on some drop-tanks and the Allies found the long-range fighter they had been looking for! The Roll Royce Merlin was, as Jay Leno put it in his video on the Merlin (ua-cam.com/video/GYcKdK7hmEo/v-deo.html), "The engine that won World War II."
that p51 has a great sound you gotta love it
I like the counter rotaing props, imo it makes aircraft unique. its prob why i like the Tu-95 and the Ka-52
Contra.
Love the sound, got my headphones cranked, totally
I love precious metal to death. It's my favourite Mustang, and the only in the world with contra-rotational props.
Griffon Power! A beast of a Rolls Royce!
That the Rolls Royce griffon isn't it?
Dryootube P-51s had Merlin engines.
This isn't a legacy aircraft. it was custom built for racing with P51 parts that were going to a grave yard and it indeed does have a griffon in it.
Yes, sounds indeed more like griffon V12. And there were actually griffons with contra rotating propellers.
Yes it is.
Royal navy Seafire engine
Still making power very impressive 💪 the pilot is pretty good too. Like the color scheme !! 👍
Wow, I never knew the P-51 could be configured for a counter rotating duo prop.
Complete Griffon install from firewall forward, probably from a late Spitfire or similar British plane.
I'm just a blues guitar player who likes to get me breath taken away
by the baddest ass racing plane Reno's ever seen. Thanx for a perfectly done
video. ...and cheers
That engine sounded smooth as silk !!
Griffon engine and contra-rotating prop, what more can a man want? This, imo, is the perfect P51
That’s one sweet looking machine!
With the introduction of the Griffon, R-R changed the firing order from that used in the Merlin.
Quote from Wiki:
"Merlin firing order: 1A, 6B, 4A, 3B, 2A, 5B, 6A, 1B, 3A, 4B, 5A, 2B ('A' being the right bank as viewed from the rear of the engine)
Griffon firing order: 1A, 4B, 3A, 2B, 5A, 1B, 6A, 3B, 4A, 5B, 2A, 6B (changed from the Merlin to reduce stress on the crankshaft)"
The Merlin has a musical hum that gives you goosebumps and makes your hair stand on end.. IMHO the Griffon doesn't sound quite as smooth.
I think the Griffon has the same firing order as the Allison. The Merlin sounds more aggressive to me, like it's got radical cams out of a hot rod. But there's no replacement for displacement, and 2240 cubes beats 1650 any day of the week.
I was at the races that year. So it wasn't the fastest, but god damn it was one of the best sounding!Just another reason I love living a few miles from the Stead airport, and in such a quiet neighborhood. Except of course in the couple weeks around race time. I don't think anyone minds the extra noise.
Shades of the old Steve Hinton piloted Red Barron of the 1970s. They are magnificent aircraft flown by great pilots. Cheers!
There was a third Griffon powered racer at Reno in the past that no one has mentioned - Miss Ashley II. Built from the ground up as a racer and not from a P51 airframe, although it looked like a P51. Lear Jet wings and horizontal tail, Cessna main gears. It was a beautiful racer, and unfortunately, never got to see its true potential, because it broke up during a race at Reno in 1999, apparently due to tail flutter.
Contra-rotating propellers were not used on WW.II combat P-51 Mustangs. "Precious Metal" is a special, experimental category, air racer modification of the P-51,
they did use contra rotating props in ww2...the sea fire fr47
No shit
no shit brian
Team pulled the Merlin out, moved the firewall back some 2ft to make room for the Griffon engine, which I understand came from an Avro Shackleton bomber. Certainly a fine looking aircraft, but it should have been left original, imho!!
So friggin what man.
はじめて
リオのエアレースを知ってから
この機体は好きです！！。
Precious Meatl ！！！！！！
二重反転プロペラや
造りこみ！！
凄い！
憧れます！！！！！！！
こんな風にマシンを造りこみたいです！！。
There is a supply of Griffon engines left from the Avro Shackleton maritime patrol aircraft. most probably came out of one of those.
They used the Shackleton quite long.

Interesting. The Italian seaplane with floats, the Macchi Castoldi MC72 set a record of 440 in the 30's. Had contra rotating props. But that was in a straight line. Wonder how much speed it costs to go in a circuit. Anyone know?
Quite a bit, maybe 20%.
Oh my, what a sound that Griffon makes, and beautiful propellers too. In a Shackleton it was horrendous, but as a single... Fantastic. Now, anyone out there have a Napier Sabre engine for a P51?
Stunning aircraft!
I really like the vegetable slicer on the front, cool! How many carrots per minute . . . .
