I went into history of these user. He's here just to provoke and troll everyone. He's doing nothing else

It was Ju-88. Now it's in 1440p visible. My dream is P-47B + Spitfire MkV / LF MkV CW + Bf-109F2 + FW-190 A2/A4 + Hawker Typhoon MkI + P40B/C + B-17E (or B-25 or B-26 or ...) and P-38 ... just anyone. (Flyable of course) ... God I made such an off topic. Sorry

-F-16C literally I bought it only to support DCS / ED. Gen +4 isn't interesting for me at all: F16 I (eventually) would like to fly is F-16A & F-16C bl.25/30 with AiM-7 missiles. I never sit inside a cockpit. F-16CM bl.50 is for me attractive like chlamydia. Lack of any serious PvP opponent accept other F-16 makes it "no go" for me. -F-18C same as above - I would rather fly F-18A -F-14 I will fly it and I will enjoy, but ... after 5000 hours in Phantom II I spend my time in L-39 (Mainly C variant for IFR /VFR flights, also as main plane in Virtual Fighter School) P-47, Bf-109, MiG-15, MiG-19, MiG-21, F-5E and F-86F is my next goal. Actually I started P-47 campaign ... just for immersion while jumping on F-86F I flew also some FC3 planes. As everybody My best regards

So far 2 vs 200 :-) I'm just joking. EF2000 is a nice 2 have. I'll buy it myself. I'm just crazy about 60' and 70'. It's the time of last air war. Vietnam, Israel-Syria-Egipt conflicts. A-7, F-100, F-104, F-105, F-4, Mirage III, A-4C/E. I like them because '70 is the end of Maneuver Air Combat. In '80 missiles are already too effective. Most combats are finished before both planes cross each other paths. It's still Air Combat but.. it's not that I killed an enemy. My missile did. "I can't get no satisfaction" Sorry for off-topic My best regards

Who cares about Eurofighter ? lol Phantom!!!!!

It's another post in these subject... I suppose every 10th guy who starts fly MiG-15 thinks that playing video-games makes him auto-cannon expert. And produces such post. Even Photos are similar.

Hallo Thank you very much for a Thunderbolt. It's great place to be. I love her to fly and dogfight. From first minute to the last. I watched every available movie regarding P-47. Most questions I have were born under impression of what I saw in there: Here are some questions. Film one: https://youtu.be/FcGoc7P1MnA 1. movie time 17:24. "Turbine overspeed light" - works different then the one in DCS. it has three positions: -off-blinking-on 2.movie time 19:46 "Cowl flaps control" - works inspite engine being turned off. There is possibility , that pilot operates hydraulic manual lever. In that case response in film is much faster than in DCS. Film two: https://youtu.be/P_eEu8VDN-U?t=600 1. movie time 21:00 - "Cowl flaps control" time response of Cowl flaps 2. movie time 21:22 - rudder effectiveness: while taxiing rudder allows to steer the plane even by extreme low speeds without using a brakes, without reeving an engine. With my best regards to Thunderbolt Dev team.

For some of the more impatient guys: God ... someday it's all came to DCS, and I'll be there to fly USN Phantom II https://www.youtube.com/watch?v=aGhTuz5axs0

I also do think so. It's ok. It's christmass. Heatblur did great job these year, thank you guys for that. Next year I'll start asking about Phantom again. Personally, I check ED forum everyday with hope I hear something. I watched every movie about Phantom II in YT, I ordered and red most books available. For now i suggest... jump to planes. Time passes by much faster once you're in the air. Merry Christmas Everyone

Technically the word "compromise" means, that both negotiating sides doesn't reach their goal. In wiki (eng.) "To compromise is to make a deal between different parties where each party gives up part of their demand." In our situation we have two sides: -For us the goal is : "to have most realistic module". -For you a goal is: "to have carrier capable F-4E" So compromise (according to definition) isn't carrier capable F-4E. Compromise is when F-4E became for example a hydroplane. It's not satisfying any of us, but it's a compromise. Either you don't understand the meaning a word "compromise", or you do understand, but you try to manipulate us. In first case you're just silly, in second you're offensive. The choice is yours. You may call a friend or ask public.

Agree. God save the Heatblur

How are you going to visually spot a target if you can't see a post? It's cleared in these post from kind 3-rd party dev. It's not a 4 lines of code if it shall work properly. There's also plenty "soft core" flight sims and they are more kids friendly. Don't mess with The Phantom Some of us don't want another MiG-21 - strange combination of "bis" (in LOBUS variant) armed with RS-2US missiles. Most of us wait for pure Phantom. You want a US Navy? It comes soon as you may read here. Wait , buy , enjoy.

It's not a War thunder!

I'd rather wait for proper B or J Don't like the idea

Yes, some 20 years ago to become 3- (C-) on 5'th (or 6th?) semester.

Shown pictures IMO are rather a case of flow SU-17 M3 vs M4. MiG 21 cone isn't wide enough to create phenomena shown in lower left or right picture. Cone is fixed far before inlet, and geometry shall prohibit shown patern. I write "shall" because one has to calculate angled shockwave. To do that you need cone geometry and Ma number. The rest is actually quite simple. Just use the drawing and simple equation: Equation works also for convex corners. Calculate yourself if you don't believe me, or use a chart if you lazy like me. Calculate as long as you wish and you'll never find an "excessive air" in MiG-21 Inlet. My best regards PS. I still do believe that one can and shall describe it using simple words and simple language. It tells the people that you actually understand what you tell. Not just quoting someone

As far as I understood, you're agree with me... In quite complicated way I'm trying to avoid too much complicated words. The older I am the more I admire people who have ability to put difficult science in simple words. Nothing wrong with that, right? As for shockwave inside engine inlet with cone it looks like that, sorry for simplification:

As I said SR-71 is not the best example because it's a Turboramjet. A unique construction, not quite good example here. As for a Concorde and other supersonic jet engines -> if inlet fails it's adjustment angle there's a risk of sudden compressor stall and destruction of an engine. It is also explained in a YT I posted here. Solution used in MiG-21 (cone) was also used in Su-17M2, M3 and allowed him to reach also about Ma=2, in Su17M4 cone was fixed in position. In spite of these it was able to reach Ma =1,75. You shall trouble yourself and watch a movie I posted. There is no risk of feeding a Jet engine with too much air. it's explained in movie. So surge doors are opening in right direction. You may block an airflow by letting perpendicular shockwave inside an inlet. It blocks an airflow, causing Pressure drop inside an air intake and may cause a sudden compressor stall. In many cases it may cause total destruction of an engine, and / or deformation of an inlet. Once again: there's no possibility of excessive air in jet engine. It's rather opposite problem. Leatherneck explanation is (in terms of fluid mechanics) like... Flat Earth society.

I see that supersonic flow isn't unknown subject for you, also a physics of a shock-wave is not strange to you, so I won't pretend smarter than I am, and I I'll avoid boring (and not so basic) explanations. Basic fluid mechanic and airflow inside of Jet engine demands, that all air that wents inside an engine must be subsonic. So No matter how fast you go, inside of an air inlet airflow must stay subsonic. It's simple. There are many quite nice explanations on how it works. I found out quite nice video. See for example these one here. https://youtu.be/636ANEHgEOo?t=81 Explanation about how works an inlet of MiG-21 starts in 4:30. Basically such type of an inlet works fine for Ma >> 2. (Here a foto of Blackbird in given YT video is not exactly a good choice, but that's completely other subject and another story). my best regards 303_Kermit

Sure. First problem (that I'm aware of) appears by Ma >> 1. There is no possibility of reaching CL max on dynamic altitude. The biggest reason of it is fast build up of a drag (while increasing AoA) which prohibits exploiting bigger AoA. In other words you may pull a stick but everything you get is loss of speed. Independently there may be other reasons of stall at big Ma numbers. Due to a gradually decreasing directional stability (on dynamic altitude while increasing Ma number), there is a possibility of uncontrolled, big angle side-slip. description of plane Behavior is given on chart: H - (first line from the top) altitude Ma - Ma number (2,1 in those test) delta v (thrird line) - rotation around vertical axis (+ is counter-clockwise) delta l (4-th line) - rotation around longitudinal axis delta h (5-th line) - rotation around horizontal axis omega x, y, z - rotation speeds in rad / s. usually x is longitudinal axis, y horizontal, and z vertical nz, ny - G in horizontal axis (left right), nz - classic G , in vertical axis. The result of these phenomena was a stall. It occurred on so called "dynamical altitude". High Ma (>>1) stall, on lower (static) altitudes is not much different, however there are more reasons for stall on high altitudes since there is no (or rather is much smaller) aerodynamic damping of plane oscillations. On approach to a speed of instability plane starts side oscillations from wing to wing. Oscillations become intenser by closing to critical speed. Main source of instability is gyroscopic moment of an engine. Depending on pilot skill MiG-21 were repeatedly exceeding maximum allowed speed. There are many relations available in YT With my respect 303_Kermit

Egypt become in 1965 45 to 50 MiG-21 FL. Syria in 1961 become 36 F-13 and around 15 FL, Iraq become around 60 MiG-21 F-13 in 1963-66. in '66 Iraq ordered 60 more "PF". They are described as inferior to our bis in various ways. "R-2L Spin scan radar was not operational at speeds over Ma =1.2 because of cooling system". After 6 day war Egypt ordered a number of PFS, in late '69 Egipt started to become MF (110 according to some sources) and PFM (SPS). I found also an information about some bis in Egipt, but with annotation, that they were flown by russian pilots. Colleague asked about weapon mostly used. I answered. He didn't asked about structure of arab Air forces, but about wapon used on them. Your answer is wery precise and surely all you wrote is precise truth, but I belive.... You missed the subject With my regards Source: "Arab MiG-19 and MiG-21 units in combat"

Would you buy a new car that's broken? Or Ice creams with salmonella? Or maybe would you like to buy flat-screen with some broken pixels? For a guy who buys MiG-21 from Letherneck it's not an old module. It's brand new, and he has right to expect it to work properly. If it's not possible, and MiG-21 is considered "out of date" like old sausage, consider similar procedure. Remove outdated product from the shelf. Otherwise it's unfair. Anyway. A subject of the topic was "how's Letherneck sims?" I gave a fair feedback. I don't demand anything. I give a fair customer review. Compared to Heatblur, Rasbam or other 3'rd party they're IMO not recommended.

Except SAU not working properly, ARU not even in slightest way working properly, Radar much to efficient at low altitude, Strangely modeled elevator behavior at high altitudes (over 15 000m) pulling hard with ARU in manual mode set in position "Take off" (strangely it's also the same position in "Auto" mode on these altitude) gives slight, gentle turn with about 2G. Plane is able to sustain 9,8 G (it was reduced couple months ago from previous bigger value). However many MiG-21 pilots reported exceding G over "11" without damaging a plane in DCS MiG sustain just 9,8G. If you pull 8,5 G crazy ARU may cause exceding G to over 10 and brake your... Wing tips (sic!) instead of bending your wing, but it's ok. You can fly (and land) MiG-21 without wings anyway. Other case is gyro sight - switch positions give different effect as expected: in pure Gyro mode only 300m range works as expected, auto ranging works different as expected (based on original flight instruction), A2G mode - shooting unguided rockets with rdr ranging and gyro gives also wind correction -> way too acurate, A2G bombing sight is a pure fantasy. It gives you precise hit point for FAB's with wind correction. A ballistic table For manual bombing with various dive angles and sight deflection angles doesn't exist. Also MiG-21 Cluster bombs are able to kill every server since I play DCS, Letherneck / Magnitude never attempted to correct these issues. Engine flames out after exceding 1300KIAS which is a total fantasy (and explanation given in DCS manual is made-up total fiction. It doesn't fit liquid mechanic, or jet engine behavior). Speed shall be limited by loosing longitudinal/directional stability and there is a proper description how it works in real MiG-21. And "the devs " are well aware about it. Modelling a proper behavior is too much effort i suppose? Engine flame out (due to over-speeding) is pure fiction (and a lie). If you report any problem the answer is "It's old module so we're not supporting it - in fact you shall be graceful for everything we make around it anyway. You shall not expect any support for an oldest DCS module. Currently all resources are directed towards F-4U anyway. No MiG-21 major updates before F-4U release." Except that, it's a legendary plane, and most neglected module in DCS With my best regards Kermit

Mostly used variant of MiG-21 in Syria, Egipt and Iraq was FL. It's India built PFM-isch MiG-21. Please note a 4 pylons and no integral gun. Also much weaker engine than the one in bis. Originally in they carried R-3S. Iraq -modified their planes to carry Matra 550 Magic Syria - lost dozens of their MiG-21 to Israeli F-15, Kfir's, Mirage III Egipt - rather bought MiG-23MS (downgraded MiG-23 with R-3S missiles and a radar RP-22 Almaz(sometimes called Sphire in various sources) from MiG-21bis. A2G - everything except Grom missile. and of course - no cannon
