When I was a boy entrant in the RAF in 1960, there was a Nakajima Ki 84 in one of the training hangers at RAF Cosford, along with a Lysander and a V1 buzz bomb. This, I think, was the beginning of the museum at Cosford, although there are museums at other RAF stations including RAF Henlow in Bedfordshire. For someone with your history credentials, I don't think you would have any problems gaining admission - should you ever visit the Wolverhampton area in Britain. Keep up the very good work.

Being a long time WW2 aircraft enthusiast and modeler, I was glad to see this review. The Ki-84 Hayate ("Gale" as I remember ) was Nakajima's premier fighter and perhaps the best of all the Imperial Japanese Army's (IJA) WW2 fighters, although the IJA's Kawasaki Ki-100 (radial engined "Tony) was excellent and was considered on par with the IJN's top fighter, the Kawanishi N1K2-J(George II). The Ki-84 also had outstanding maneuverability in keeping with Nakajima's emphasis on this capability - earlier shown by the Ki-43 Hayabusa ("Peregrine Falcon")...Allied code name Oscar. Just my own opinion but I also consider the Ki-84 the best looking of all the IJA's fighters. Main downside of the Ki-84 was rushed production and spotty quality control - particularly with the engines and main landing gear. A few over 3,000 were made. Best Ki-84 models available are Hasegawa's 1/32 and 1/48 plastic kit offerings. The older Tomy 1/32 plastic offering is pretty good, but not as good as the Hasegawa kit.

Your comments on pilot quality is so very true, reading many written stories from the era, the top New Zealand Ace Colin Gray first victory about deflection, and his surprise of hitting his opponent, it wasn't where he was aiming. Also the story of the Canadian Ace/Test pilot? who when flying over Europe encountered a FW 190 in a Spitfire, after much jousting and sweating, combat was broken off, saying that neither could gain the advantage, and it was lucky that he had an advantage of have flown an FW 190 which he thought the German pilot hadn't flown a Spitfire.

[@LordNinja109]

The Germans did have a unit that flew captured allied aircraft to different bases for hands on instruction. Even if he didn't fly it, there's a fairly good chance the German may have sat in the cockpit and gotten first hand accounts of the limits and performance of the Spitfire

Differences in training between Japan, US / Allies and Germany sounds like a great topic for video, since the pilot training is major factor in how well the airforce performs.

[@jj4791]

So is tactics. Individual and Wingmen. And overall philosophy: “The first duty of Eighth Air Force fighters is to destroy German fighters.” Most importantly is Production. The US defeated the Axis by out producing them. Even the Brits and the Russians relied heavily on US fuel, airplanes, and equipment in the turning point of each nations respective wars. Germany is about the size of Ohio with about as much oil. Japan was an isolated island network with rice and ox carts. The obscene delusion of those two was real. “I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve.”.

[@ToreDL87]

@@jj4791 Not to be the triggered weeb, but still, if you take a look at how fast Japan modernized after centuries of isolation, they managed to sustain nie-on constant conflict one way or another since the early 1900's. Within their capabilities of course (just to point that out), but once they got serious they evicted almost everyone, almost entirely, from the Pacific Theatre, within just a few months. They were no slouches, and at the start were a force to be reckoned with, so much so that U.S intelligence were on the job. As you said it was philosophy, and might I add in-fighting, lack of humility, and over-all underestimating their opponents, either one of which was enough to bring them down, that brought them down, and even then it took a massive, coordinated, international effort across 3 continents & 3 oceans, spanning 3+ years. Similarly, not to be the triggered wehraboo, Germany was pretty small compared to the U.S, nobody denying that, but they recovered from the combined effects of the Versailes Treaty and the depression, and became able to wage war on the entire European continent, within less than a decade, and similarly had everyone sweating for a while there, it took 6 years, 3 super powers and almost immeasurable money to have them call it quits. And that's not counting the human cost. So.. not for a lack of trying then! Not to get too political, I'm siding with humanity & common sense, of course, the bullies had it coming, and they got what for. But my point is that victory was not written in stone, and in war it never is. For how limited their means were, they certainly had everyone else on the back burner for a good while, and the fat lady didn't sing until it was through with, as anyone certainly could attest at the time.

The comment about magnesium fires in the B-29 hit home. I experienced a magnesium fire many years ago (not in an aircraft, story too long to tell here) and it was nasty. No one was hurt, but the pucker factor was high. I can’t imagine it in any aircraft.

[@donbalduf572]

Come to think of it, didn’t Germany make considerable use of magnesium in WWII aircraft?

[@fafner1]

I once got slapped down pretty hard on this site by someone who seemed to know what he was talking about, and who claimed the whole R-3350 magnesium part story was a canard. In any case he pointed out the R-3350 became more reliable after direct injection was introduced. This makes sense as it had a reputation for burning exhaust valves, which could then serve as a glow plug to ignite the intake manifold during the intake stroke on the carbureted engines. Lemay switching to low altitude night bombing also helped engine reliability, as it avoided the long climbs to altitude with a full bomb load.

[@fistofthetiger1591]

So far as I can tell, the Frank is somewhere between a Corsair and a hellcat. Approximately somewhere at the middle of production of the American fighters as far as it's performance. Not at all a bad set of company to be in! Thank you very much for this series of interesting videos!

[@isolinear9836]

In terms of operational performance, the Hellcat and Corsair have a decisive advantage over the Frank in that they are Carrier aircraft. And ultimately in Warfare overall, the Frank is far less valuable as an aircraft by comparison. Even assuming the American aircraft (and Zero) were hypothetically inferior aircraft in strict air-performance standards, it's a historic fact that Carrier embarked aircraft at Sea consistently devastated Airbases on Land which were defended solely by its own land-based aircraft. You actually need a "Network" of Airbases and Air-defenses to realistically defend against a single Carrier Battle Group in any meaningful way, and even that is really only a delaying strategy - it's a "Shield", which is useless if you don't have a proper "Sword" to strike back. This is due to the simple fact that an Airbase is a stationary target - a known quantity - which makes "initiatives" against the Airbase so much simpler to implement; for both logistical and technical matters of planning, for coordination, for execution, for morale, etc. - the Airbase's position is fixed and for the most part, immutable. In stark contrast, a Carrier is a "mobile target" - for an Enemy it is an unknown and often an unknowable threat - which must first be "found" and properly tracked for ordnance to be launched and delivered (targeting data and criteria is NOT a matter of getting a ghost return at a random bearing and launching a missile blindly into the aether of that general direction, nor does Satellite, Sonar, GPS, etc, adequately solve this problem) - and needless to say, doing this in such a systematic and timely exercise where multiple delivery vehicles must saturate/penetrate the Carrier's layered defenses in a VERY small window, is a compounding problem when SIGINT is VERY perishable. It's not a simple task at all for the US Navy to solve against itself. Now match that task and timetable of the Carrier as it concurrently solves the converse problem against the Airbase (or even a network of multiple Airbases and nodes). The one with the inherent advantage is obvious. The Carrier is capable of deciding the terms of engagement because it doesn't need (and does not have) the same Acquisition requirements (and Target Criteria) that the Airbase needs (and has)... What you cannot See, you cannot Hit, and thus cannot Kill. But what can See you, can Hit you, And thus can Kill you. The fixed Land-base is a literal Sitting Duck vis-a-vis the mobile Sea-base. No air-defense, no matter how dense, well-trained, coordinated, overlapped with firing arcs of varied platforms and weapon systems, etc, is going to survive against a Carrier strike package that has been planned, pre-programmed and practiced for years in advance (sometimes decades in advance on an institutional level). Assuming open warfare is declared by both sides, the initiative is naturally incumbent on the Carrier group - and its first move will inevitably be an immediate Missile launch. The Airbase's pilots, radars, infrared sensors, etc, can't even hope to see, let alone track, all the low-level, low profile, terrain folloowing, etc, cruise missiles the Battle Group's escorts will be firing from their VLSs alone, who's routes are pre-planned to use the terrain to mask their signatures (including acoustic) from those sensors once they reach landfall, then to arrive at designated times to saturate MULTIPLE Airbases and targets effecting those bases at different levels. Certainly not given the expanse of the network and Airbases to be defended (that's a LOT of real-estate to defend, both physically and systematically, and breaking one link can result in a cascading failure of the whole. A highway or railroad or Grid hundreds of miles long and girding everything from communication cables to waterworks only needs to have one small section or hub or substation or bridge, etc, to be collapsed in order to influence the battlespace against the Airbase, or even render it inoperable). Why does the Carrier group (and its assets) strike so easily and immediately, while the Land-base (and its assets) cannot? Simple: Because Land-Bases, Mountains, Rivers, Valleys, etc, take a LONG time to "Move" or "Change". TO put it another way, its easier for the USA to tweak its digital maps and waypoints than for its enemies to move Airbases and Mountains. The Footprint of even a single Airbase(s) is enormous and prone to that enormity and connectivity, from infrastructure to Command and Control. In contrast, the Carrier Battlegroup is comparatively small and relatively self-contained. All things being equal (or even slanted against the Carrier): While the Airbase is just searching for ways to attack the Carrier Group, the Carrier Group simply implements a pre-planned response because it knows EXACTLY where the Airbase is and has probably known for years....in all likelihood, before the Airbase General can even begin to validate his options, The Carrier's Admiral HAS ALREADY LAUNCHED. This dynamic isn't new...it literally hasn't changed since WW2 - it's asymmetric and "unfair" as Hell. It's an asymmetry analogous to the Army's tank maneuver warfare against fixed fortifications....only worse. MUCH worse. And this asymmetry has universally been a powerful weapon in the contest of "who's system of men and machines collapses first". I specialized in Anti-Air warfare in the US Military, and I can tell you, I do NOT want to be the Airbase (aka "Sitting-duck" conducting Mass-Casualty simulations) on the receiving end of an inbound Designated Time on Target (DTOT) strike package sent by a US Carrier group. For example, against China's string of pearls, beginning (or ending) with China's STC Airbase network, I would conservatively guesstimate that at least 80% of American VLS Missiles will hit home. That's no insult to the Chinese. Were such a VLS barrage to be launched against an American Airbase with a reasonably deployed and drilled air Defense and CAP, forewarning, etc, I would be "happy" if ONLY 80% of US cruise missiles struck home. And as for the Carrier's follow-up... Air-Defenses be damned. Armor against Warheads... I say Warheads win. No wonder the US Navy was happy to forgo an Interceptor role for its "Fleet defense and CAP", while leaning on "Less capable" aircraft with heavier and autonomous payloads... .... to deliver what amounts to a Coup de Grace. The Carrier can coordinate a DTOT using surface and aerial platforms with relative simplicity (that's not to say this is "Easy", but it's not entirely "New" to the US Navy), a process its Enemy on Land would struggle to find itself in a position to consider (Heck a lone DDG Burke can conduct an STOT on stationary targets with devastating effect), projecting force to specific pressure points in different spheres and multiple locations, and forcing the network to react and compensate, wasting most of their time, assets, and ultimately stressing their ability to cope with system shocks (like a person compensating for injuries by overburdening other parts of the body, causing more injuries and/or making those parts vulnerable to attack and even innate collapse). But a Land-Base (even a Carrier) doing this against an Enemy Carrier? That's a WHOLE different ballgame. You can see why the Chinese are intent on creating their own Carrier Force (again, not as easy as it sounds), and the Soviets before them. In WW2, the Land-base vs Carrier Base advantage was always in favor of the Carrier, often laughably so. Today, with the integration of GCCS, GPS, terrain-following missiles (there is no "terrain" to follow for a missile trying to find a mobile Carrier at sea), etc, the Carrier has only opened the gap even lop-sidedly in the 80 years since WW2-era technology. All of which makes the exercise mostly moot, because many people in power ALREADY KNOW THE SCORE (even if they pretend otherwise in public). There's a Sword of Damocles over the World's Sea Trade, and US Carriers are the Tang of that Sword. The USA can simply signal that the US Navy might stop/inspect/detain/"or worse" vessels and infrastructure transporting goods from the Baltic Sea to the Mediterranean to the Persian Gulf to the Straits of Malacca, etc. Everything from the rise in insurance for the ships and their crew, to the viability of companies to make transactions for goods that cannot be delivered...the Sword of Damocles is usually enough to prevent the necessity of such a threat being carried out. Again, when it comes to "Carrier aircraft vs Land-based aircraft", most people with "money on the line" have a peculiar instinct to Know the Score - even without knowing anything about aerospace engineering. (Foreigners and Domestic "you-know-who's" keep dreaming of perfecting the Pearl Harbor attacks on American Carriers through various means, whether Cruise Missile or Submarine or even Nuclear Strike. But even when the Japanese had the most detailed and actionable intelligence on any enemy Carrier in the History of Warfare (USS Enterprise), right down to the MOORING BOLLARDS and the MINUTE of where and when the USS Enterprise was supposed to arrive and be tied up - straight from the mouths of their Japanese populace sitting right there on Oahu watching the Harbor.... SOMETHING inevitably went wrong with the Japanese plans....plans tend to do that. Only flexibility and adaptability can remedy that inevitability. Even if everything went right, they still had a LOT more US Carriers to deal with for the duration of the War. In that moment, the Japanese could only count on their most flexible tools to mitigate that inevitability...their own Carriers, of course.)

They also were never trained to take initiative or improvise. They played follow the leader and if the leader were eliminated, the remaining pilots were lost and unable to continue a coordinated attack. The higher decision makers frequently were not pilots as well, so the orders were given by incompetents. For example, ordering Hamps to fly round trip from Rabaul to Guadalcanal when that Zero version carried less fuel than the A6m2.

Then again, the FIRST place the Ki84 saw combat was in China (A sentai that acted as 'test unit' before normal deployment? I think?). The bases were still well supplied and the maintenance team was still pretty intact. On top of that, I think a sizeable chunk of the Allied "opposition" was still flying a variant of the P40--The CBI theater was sort of a backwater, when it came to priority of receiving new model aircraft. In spite of that, I don't think I heard about any of the CBI deployed forces suffering any out of the ordinary losses (then again, I dont' think I've read too much on the theater after the AVG was absorbed into the USAAF).

Excellent, Greg, as usual. Turns out my Dad might not have been helpless in his F6F-5 if he'd met a Ki-84 over the Philippines in 1944, and the F4U-4 he was flying in 1945 would have been a near-even match. I've read a handful of accounts of Japanese pilot training, and they've had the brutality of that training in common. Seems more than a little counterproductive to me - making unnecessarily miserable the lives of people you're going to be depending on doesn't strike me as a smart approach to national defense. I do agree that there's a definite "family" resemblance between / among late-war Japanese fighters. Dad shot down a pair of Tojos during the extended Leyte Gulf battle, and from your photos, it's easy to see how, depending upon distance and angle of view, they might just as easily have been the Ki-84 or maybe something else.

FYI, Ki-84 max acceleration based on structural strength is 7 G and ultimate load is 12.6 G (with safety factor of 1.8). I am not sure where did that 5 G come from in the translation, but Japanese document lists pretty much the same acceleration limits as were expected from a Zero or Ki-43.

[@MAG3_Hiromachi]

Another correction, fully loaded is a standard load without external ordnance or fuel tanks, which is 3763 kg. The loadout with external fuel tanks or with bombs would be "special load" as indicated in Japanese manual.

[@GregsAirplanesandAutomobiles]

That 5G number is listed all over the place in the documents and it makes sense considering the spin and other warning about stress on the airframe. I think they initially planned on a 7G limit, but it didn't happen in production.

An excellent summation to yet another fascinating aircraft. I like your point about the pilot training and quality in war time Japan. Thank you Greg. Happy New Year to you and yours!

[@Splattle101]

Another good, informative video. Cheers!

[@Mtlmshr]

I’ve now watched all four parts about this aircraft that you have done and I must say that this has been a very in-depth analysis of this aircraft. Props to you and your research on this plane. It takes a certain passion to do the amount of work that you have done to compile all of this information and for that I thank you. Before this series I honestly did not even know of this aircraft or am I that much into these types of things but you got me interested in this particular situation and I thank you for that!

[@watchmanschannelofdespair]

You're information is top notch! While the Japanese "Zero" was a great early war fighter-lack of armor protection and self sealing fuel tanks notwithstanding-I always favored the "Frank" and the "George" as my favorite Japanese WWII fighter planes. Just imagine how much better they'd have performed under optimal manufacturing conditions?

[@leojeidy1143]

Another great video thanks Greg!

If I ever want definative info regarding Aircraft performance whatever the era, I tune into Greg's Airplanes..! Well done again Sir....Thankyou.

[@talgov01]

Excellent video. Thanks!

[@fazole]

I spoke with someone who went through just flight training for KAL about 30 yrs ago and he said their senior instructor was known to slap cadets! He related that one cadet did not park his training aircraft right on the line on the ramp and this cadet was verbally and physically attacked.

[@haitianspaceprogram735]

ok...this one did it, should have been on patreon long ago but this series is the tipping point

[@kevlarmac10]

I can only watch things that give me information and knowledge these documentaries are very good and stimulate your thought process history rules

[@GeOl011919954]

Very interesting subject I really enjoyed your video thank you for sharing 👍

[@mikepette4422]

I recall reading in multiple places a statement from a Japanese Navy Pilot ( PS: I believe it's Saburo Sakai discussing and highly praising his squad mate Muto and their time on mainland Japan training new pilots for the George) about flying the Kawanishi Shinden "George" that when they faced Hellcats and Corsairs they felt like they back in 1942 and dominated the air battles. Of course this was with veteran pilots, the last few Japan had in those days. And while the George and Frank are not the same aircraft I think you can see what I'm getting at. These late war Japanese fighters gave the experienced pilots more than a chance against the Allies best.

[@silincer5186]

Sorry to correct you here! The Shinden(Magnificent Lightning) is a different aircraft. Full name Kyushu J7W Shinden. The George is called the Kawanishi N1K-J Shiden (Violet Lightning).

[@AkkaAlbatros]

the shinden was the dogfighter so if a pilot was even a bit decent could easily shoot down everything. ki84 was more towards the bomber interceptor . it could intercept even b29s at the heights they were flying.

[@silincer5186]

@@AkkaAlbatros that's wrong! I guess people mixed up the Shinden and the Shiden because of being similarly named.. The Kyushu J7W Shinden is not a dogfighter but an interceptor. Shinden was built with short range but fast climb rate as a response to US Heavy bomber. The Kawanishi N1K-J Shiden and the N1K2-J Shiden-Kai code-named George are dogfighter. The Shiden-Kai variant is one of the best dogfighter produced by either the Japanese or the American.

[@waltergreif4836]

excellent review of pacific fighters performance well done!!

[@plasmaburndeath]

Just started the video, but I wanted to thank you for being so "Frank" with us... Get it Frank/fra... I'll get me coat, and I'm here all week everyone! 😀😆

[@fighterace316]

Hey Greg, that was a fascinating video and a real eye opener. By that I mean, in a couple of WW2 aircraft books I’ve read the author/authors I seen say the Frank was an aircraft that was not outmatched and never outclassed. Where does that come from.?? I’m looking forward to your next video.

[@boomerbaxter8420]

This is not an attempt to blow sunshine up your kilt I assure you, but dam, you produce awesome videos, I loved this series on the Ki-84 a great deal, it was a real learning experience . The Tony has always been my favorite of the axis fighters and I am looking forward to seeing a video on the Tony 2 ? or the one with the the 109-G's engine in it, thank you for all the hard work you put into your videos, it puts them on a higher tier than most others on this platform and its amazing how, a little thing like factual information is so hard to find in most of what is being put out these days, please keep up the good work and I look forward to your next video .

[@GeneralJackRipper]

For more information on the bomber issue, I recommend Gladwell's _'The Bomber Mafia'._

[@brianford8493]

Brilliant analysis.

[@dmw7320]

Great content as always hoping to see you do the J2M .

[@Leptospirosi]

You know, I really would like to see these analytical methods applied to the Vietnam era jets, specifically the F104 Vs Phantoms and Mig 21, just to debunk some myths against the Starfighter. Could prove VERY interesting! 😎

[@GregsAirplanesandAutomobiles]

Everytime I make a video about post WW2 stuff, almost nobody watches it.

[@Leptospirosi]

@@GregsAirplanesandAutomobiles may be, but the F104 especially gets very strong opinions against and in favour. There is very little literature about it especially about the Vietnam war, so I guess it would be something totally "unique" with your knowledge thrown in, worth a link outside the you tube platform as well! 👍

[@Hypersonicmind]

@@Leptospirosi Hartmann hated the F104 and quit the Luftwaffe over his protestations. i think some German politicians were found guilty of taking bribes from Lockheed to get the 104 approved. i must say, a gorgeous plane.

[@JohnnoDordrecht]

Fantastic video , thx a lot .

[@shaider1982]

One of the problems was that the B29 did not provide the engine with enough cooling and the cylinderhead wasn't large enough to dissapate heat. As mentioned in a video by Curious Droid, NACA did a study to correct these problems.

[@dyer2cycle]

..although the R3350 eventually became a very good engine, at the time of it's deployment on the B-29's, it was rather atrocious...I can't understand why they didn't re-engine it with the Allison V-3420, as tested in the XB-39...quite a bit more power, more reliable, and overall better aircraft performance...yes, it would have interrupted production to make the changes, but it seems like it would have been worthwhile, and the problems with the R-3350's were causing disruptions of their own..heck, since those early R-3350's were only managing 2000-2200 hp(when they were running right), I also don't understand why they didn't just use the R-2800 as a stopgap measure...

[@Raptor747]

While an admirable advancement in Japanese fighter design, the reality of WW2 by 1943-onwards is that numbers, logistics, training, organization, and maintenance mattered far more than a small edge in performance. This is also why the Hellcat remained so overwhelmingly popular in the US Navy despite the problems of carrier landings with Corsairs being worked out by the British--the Hellcat was a lot easier to maintain and operate from a carrier, on top of being familiar and easy to fly. The US Navy found the Hellcat's performance to be perfectly fine even up to 1945, because even if the best, newest Japanese fighters that were rarely encountered were technically superior in performance in several metrics, it was nowhere near enough of a difference to make up for the overwhelming advantage of simply having highly capable fighters available consistently and in large numbers. I think the logical extreme of this dynamic can be seen with the Me-262: despite being a practical jet fighter with excellent firepower, visibility, speed, climb rate, and dive speed, US and British pilots were more than capable of dealing with them in the numbers they could be deployed in. A few small tactical victories are meaningless in the face of overwhelming strategic realities backed up by tactical realities that represent 99% of situations. The Hayate was an attempt to get the absolute peak performance possible for a fighter that Japan could build--but even this came at the cost of unusually strict limitations on G-loads and certain maneuvers due to an airframe that isn't as rugged as normal in its attempt to chase maximum speed, climb, and acceleration from what they could build.

[@johngregg5735]

Great video! I'd make a joke about having 'Zero' interest, but some folks wouldn't realize it a play on words.

[@chrischiampo7647]

Excellent Thanks Greg Enjoy All Your Details and Factual Information With Sources 😊😀😎👍🏼

[@benrobertson7855]

Thanks for all the detail in your vids.when you are into a topic,the more is really appreciated and important .it’s my one complaint about U tube that the tec details get lost for drama and” rounded” information . Constrained by a short vid. your channel constantly provides the detail wanted.and even though I aren’t a plane person,I watch your channel because of the knowledge and information .thanks very much.

[@thomaspinney4020]

Another fine video. You go into the practical details of real world, not just the posted top speeds of the aircraft. I understand you tend to prefer to look into one aircraft type at a time, but could you give us a reference on the comparative ranges of WWII fighter aircraft. I know you did this for the P-47s but it would be very interesting to compare how far these aircraft could fly on a ferry mission and what was a typical war load range for them.

[@tonykeith76]

Great video Greg! ( I love so deeply the Hayate, that I chose it as my nickname in DCS ) Greetings from italy

[@Kollider115]

Great video, please keep it up!

[@kirbyculp3449]

Greg, regarding the brutality and prevalence of slapping in the IJA I recommend to you and your viewers the trilogy 'The Human Condition' directed by Masaki Kobayashi.

[@fidenemini4413]

Great works! I would like to see a series of N1K2, the naval counterpart of KI84 in terms of performance.

[@thomasbernecky2078]

So when do we get the Frank vs. the P-51? Thanks for this extended look at a plane I never knew in any detail before.

[@reaperthemad8731]

[@Burstix]

Greg, your statement at about 36:25 is gold. I really enjoy your videos and thoughts on many things.

[@GregsAirplanesandAutomobiles]

Thank you, I appreciate that.

[@crimony3054]

Yeah but you guys know the state of the art in engineering is what goes into aircraft, and the state of the art engineering comes from upper level engineering courses at university, and better understanding of upper level engineering can only help a pilot pilot. There are always exception, but on average, more education helps.

[@Burstix]

@@crimony3054 I will agree and say it's not a bad thing to have more education (on subject) One thing to note, planes are a lot more complex now than they were back in the day.

[@edrosenquist6541]

I hate to say it, but this is a beautiful looking plane!

[@andrewpease3688]

Thanks for giving me something decent to watch over Christmas. Ki84 was amazingly competitive considering what Japan was going through at the time. Tigercat vs Hornet vs twin Mustang would be really interesting. Why does the TM work so well?

[@jj4791]

The design eliminated the center fuselage pod along with its profile and interference drag, and negative effect on lift-induced drag.

[@juicysushi]

This is a really good video. The explanation on the radios improvements might be found in the Drachinifel video on the Zero. It was a geographic issue rather than a radio issue. The South Pacific had much more interference than the Japanese home islands, and that was not really understood at the time.

[@kennethzollars3408]

love this stuff

[@apfelsnutz]

A truly great video, that deserves an EMMY or at least a TUUBY ! Thanks so much for all you do on this channel ! To me, it's easy to see that had the Japaneese the quality pilots that we had, it might have been quite a different air war in the Pacific. If you are ever in or close to Rosamond, CA., (Circa Edwards Airforce Base), Let me know, you deserve extensive flight time in my Navion ! ... 07, Sir !

[@kenneth9874]

The japanese started the pacific war with the advantage in pilot experience and quality but was overtaken

[@krzysztofkuza4228]

Love Your videos. And I'm really happy to see another Japanese fighter on your chanel. I'm hoping You'll make videos about Nakajima Ki-44 or Mitsubishi J2M at some point. They're not well known planes and not typical Japanese fighters. For me these two were always really interesting machines.

[@ndensham]

[@dmain6735]

[@JoshuaC923]

Makes ya wonder, what is 'shit runs downhill' in japanese.

[@WildBillCox13]

Nice looking plane.

[@Pierluigi_Di_Lorenzo]

40:44 The Wright R-3350 was used after the war in some prominent airliners (Lockheed Constellation, DC-7), up to the 1970s! And also in some military transports and seaplanes (Fairchild C-119, C-123, Martin P5M). The demands on the flight engineer with regards to temperature control were very high though.

[@GregsAirplanesandAutomobiles]

Yes, flight engineers back then had their work cut out for them, of course the 3350 got better with time, but during WW2 it was a problem child.

[@icewaterslim7260]

This series was a comprehensive gem for fans of lesser known Aircraft. Sounds like the Ki 100 as well as the 61 just might've been of a sturdier airframe. if slower. All i know about it is gleaned from what little I've read ( and I've read as much as I've found) along with your fascinating piece on the Ki 61. It seems the Ki100 usually wanted to go vertical and anything gained in distancing from any fast adversary with it's diving speed would be quickly forfeited in trying to follow that up with any level run. Anyway I'm still keeping my vote for the radial engine variant should you do another Japanese aircraft but will be an appreciative audience for anything you should choose to cover from anywhere.
