Hi! I want to say thank you for the mod! So current situation is dictating to us to delete all lines related to radar because it coflicts with last changings of the new radar grid!

МиГ-21 сейчас стал нормальным самолетом! Я понимаю, что в это трудно поверить - с 2014 года на нём уже многие "поставили крестик", но это правда! Это больше не уфолет! На нем можно и нужно летать и получать удовольствие! У него правильные параметры виража, есть типичные срывные режимы на закритике!

Всех поздравляю с новым апдейтом флайт-модели, которая наконец починила ему многие проблемы и он наконец-то стал летать в рамках общих принципов аэродинамики и даже показывать признаки присущие дельтавидному крылу! Поскольку я лично был причастен к этим улучшениям и вел переписку в англоязычной ветке с разработчиком - я рад больше всех наверное! Но хочу сказать спасибо тем кто помогал мне разобраться, как ему положено летать: =RAF=FAB999, FF*CMF*04, =RAF=Maffler, AAK! мои тесты текущей флат-модели: больше нет полёта пузом вперед: https://youtu.be/3QhvY4gaBko, броски с крыла на крыло во внешнюю сторону виража - наружу: https://youtu.be/IfNcejnO4KI, заброс в сторону виража при даче педали в сторону виража: https://youtu.be/P-VwOfRzJlw, больше не ломаются шасси - посадка с превышением приборной, 340 км/ч и вертикальной скорости, -5м/с на касании: ссылка на мою переписку с разработчиком: https://forums.eagle.ru/showthread.php?t=266878

So, i congratuate everybody with new update of the flight-model and it's fixed many problems which we've been watching before: 1. Old stall behaviour when plane was going to fly by it's belly to forward with crazy 40° AOA in level flight. There was no any other features on critical AOA at all! Done! 2. Now we have pronounced stall behaviour after 32° (35° on cockpit gauge). We have rapid wing rocking, throws from wing to wing in turn and it's going to opposite side of the turn, out of the turn as it has to be because its tipical for delta shaped wing! It is not so simple and not so scripted as we can think, for example if you push a pedal in to the side of turn the wing rocking starts into the turn too! And it's great! Is'nt it? 3. We have central directed stall without wing rocking with spetial conditions! 4. We have inproved behaviour while take off running! No more crazy jumps! 5. We have much more realistic duration of the gear while rude touching! I was trying to brake the gear on 340km/h and -5m/s vertical speed and it's Ok after that! Done! 6. There is no more suspitious wobbling of the nose on pretty good speed 400-700 km/h. Also there was hard to trim. Done! 7. I have noticed there are no more UFO down directed spot lights to the ground when it extended. Done! 8. Bug with critical reducing the heat signature of the jet nozzle with afterburner. Done! Dear developers! I sincerely thank you for the work you've done!

So, i've got the same issue! My FPS is dropping approx. -20 I've made a detailed explanation video with perfomance data on the screen: https://youtu.be/17CcrnoUF_w

There were taken M-2000 fuel 39% and JF-17 fuel 100% Their weight is equal. Overall dimensions are similar. Take a look: Of course the other aircrafts in DCS is going to go forward much faster! )))

I like to think that current flight-model is a result of my notes to developer upper in this topic but i am not sure! )) So what we have now? The developer just turned off the stall and spin behavior of the aircraft after 32° AOA (on the cockpit indicator it is 35°). It is clear! Also, it seems to me (but it is just my fine feelings), the effectiveness of aelerons close to critical AOA are slightly reduced. The reaction for the pedals seems slightly better than earlier as it has to be! Obviously, now it has much softer reaction of the gear! Aircraft is unrealistic jumpy while running. If you try carefully to take up the nose wheel and hold it, the plane is going to airborne itself but if your stick is not on the exact center line in roll direction you will have the rapid jump from one main gear to another and throw you in roll! It's very strange behavior because it has to be in another way! It has to look like smooth release by the main gear of the runaway! Slight touch of one gear is irrelevant and has not notable! Also, it has no buffet before critical AOA. It has no rocking from wing to wing on critical AOA. So... we just have to wait and ask the developer to continue the work have been started!

Look at his broken trajectory! Something wrong with this flight model )) He is able now to pull the stick as hard as need the pilot to reduce the radius of turn to very low value! Please guys dont fly like that on Cold War! Fly realistic! Use the better thrustweight ratio of the MiG-21! Use the vertical oblique loops against F-5 in the BFM fighting! Dont drop the speed! Its the death for any aircraft in all times! Study how to fight and lets do it in proper way! Good luck! See you in the sky Your _SkyRider_

Last days I was flying against MiG-21 on ColdWar and i may say - it looks terrible from the side! The pilots of MiG-21 now are flying constantly on hi AOA at low speed with afterburner! It's absolutely unreachable for F-5 now to get his six and its is not correct! I know it because F-5 has better turn rate at speed range 300-500 knots on ground level! The turn rate of the F-5E with full internal tank starting from 12°/sec and growing to 17° per second when fuel is burning to 1/4-1/5 of the tank quantity. That is pretty good for this generation! Defenetly MiG-21 has worse aerodinamic and cant compete with him in horisontal maneuvers! MiG-21bis has almost the same turn rate only with emergency afterburner! It cant keep this rate for long period of rate fight! Usual picture of the fight with similar amount of fuel is like the MiG-21 keeping the same turn rate around one circle and after that his speed goes below effective range and he is slowing down in turn! Immideately F-5 is closing to his six! MiG-21 has the similar parameters of the turn but now without stall, the pilot watching like F-5 going for him in the turn, just pulling the stick back and loosing the speed and reducing the radius of the turn. F-5 loosing the speed trying to follow but he cant to reduce the radius of the turn because in this case he is going to slow below 260 knots and just freeze in the air like a bait! This is good example of what i mean: The style of flight on the MiG-21 for those pilots who are not worring about realistic - on the Cold War server:

and last one

and more pages

Now the developer just turned off the stall and spin behavior of the aircraft after 32° AOA (on the cockpit indicator it is 35°). Also, seems to me, the effectiveness of aelerons close to critical AOA is little reduced and reaction for the pedals are better as it has to be! Obviously, now it has more softer reaction for gear and aircraft is unrealisticly jumpy while running. It has no buffet before critical AOA. It has no rocking from wing to wing on critical AOA. So... we just have to wait and ask the developer to continue the work have been started after very long break! I picked here some pages from the MiG-21Bis - Pilots Flight Operating Instruction:

Dear developers! Our community of virtual and some real pilots, (=RAF=, FF and others) are really appreciated the work has been done with flight-model of MiG-21 last update! Generally flight-model is better than before! The plane feels better on the stick, better while increasing AOA! It's better while touching the runaway! The main gear are stronger as it has to be and not so easy damaging! Thank you for that! But front gear looks too jumpy! Yeah its going to jump if touching was inaccurate! And it looks like nose now is lighter! To be clear even in air nose feels to has less weight! Plane even on 700 km/h very sesitive to little movements of the stick in pitch and tending to wobble! This behavior easy to see even while trimming. Triming now is more complicated in pitch than earlier! There are some very importants remarks! 1. Excessive reaction in roll. Effectiveness of ailerons is too hi almost at all modes of flight. Starting from very sesitive to little movements of the stick in roll direction on landing while approaching, even using curves on stick! Especially around zero zone! As we know on low speed any plane feels less reactive on stick! It can't has the same effectivenes as on hi speed! But now we can see opposite picture! Roll is equally effective on landing, on 700 km/h low alt and even on critical low speed on hi altitudes! The real ''stick in the eye'' is the same effectivenes in roll while hi value of AOA! As we know than more you pull the stick than less effective ailerons because of changing conditions the flows on airofoils! Close to critical AOA ailerons has to be ineffective! Now we have opposite behavior of them! 2. We see the AOA has changed judging on gauge in cockpit and DCS tray and we can see it in Tacview! The exact amounts is discussing and we hope you have enough certain information from real sources! But we have info that critical amount of real MiG-21bis is 28° in absolute value! So in cockpit it may be 32° and we understand it's up to you! But now we are able to pull the stick and to see like the needle is laying on 35°... Ok. But again after that tha plane can't to fly in horizontal flight with 40° AOA in DCS system tray and 1G load! We see steady flight with this conditions! More than that and again the effectivenes of ailerons are still very good! On such hi AOA even short time before nose has to go down ailerons has to be less affective than reaction on rudder! 3. We know that tipical behavior of the plain close to critical amounts of AOA is buffet! We want to see jolting, shaking before critical AOA! It's preceding the distinctive throw in roll and shaking in yaw that we know like tipical behavior of the planes with triangle wing! Now thankfully we have this tipical throw! But its has to be to the opposite direction of the turn! Not to the right side every time! This throw is going because changing the conditions of the flows on left and right wings in different ways and it makes the lift on the inner wing and this lift is forcing the plane out of the turn in roll direction! 4. Pay attention, please on condition when engine is stopping especially while stall! It's going to work while quite wild stall! So, we would like to see such behaviour in current flight model! Thank you for the work!

First main rule to fight succesfully is to maintain effective speed in turn! Any maneuver is a turn or part of a turn! Thats why you have to stay in turn on speed 260 - 550 knots! Dont loose it in fight with MiGs and you will win!

Enough clear information of behavior MiG-21 on such AOA and speeds. Sorry for my stile of translation in English! But this last changing has to be in Bulgarian and German Flight Manual of MiG-21bis!

Так, разраб мне ответил что меня услышали ипроблема будет донесена до разработчика флайт-модели!

Thank you Hiromachi!

Отписался в англоязычную ветку о проблеме: https://forums.eagle.ru/showthread.php?p=4252877#post4252877 Дублирую сюда: общее видео со стороны про управляемость по крену на критике: видео из кабины: трек: в англоязычной ветке прикрепил

So i made a short video and the track with demonstration of good effectiveness ailerons on hi AOA: and second video: MiG-21 definitely can't to fly with AOA 40° in horizontal flight because the flow is not enough to keep his aerofoils effective! MiG-21 good aileron effectiveness on critical AOA.trk

Yes, now it goes far away out of 32° AOA and if you pull the stick carefully around 35° aircraft yaws out the turn rapidly tends to make a half spin and shows great loss of stability! But on any hi AOA it keeps very good turn maneuvering i mean ailerons effectiveness! That looks wrong! As i know tendention to yaw spin on hi AOA is tipical behavior of the aircrafts with triangle shape of the wing but before that we have to see decrease of aileron effectivness! Now we dont!

Hi! I've got a question about IAI Kfir C.2 in DCS! As i know some Israeli guys working on it! Please give them some credits and help to be an official developer! We are defenitely need this interesting craft in DCS! Here is a link of their Discord: https://discord.gg/qAvumV Thanks!

Hello! Please would be good to see some later version of Sidewinder on MiG-19. For some hypothetic arabian MiG-19. I understand there was never MiG-19P there but anyway for game procces! And please fix the rip off the missiles while 5G Thanks
