TIP: use ASC Refuelling Mode instead of Auto-Level which doesn't use Autopilot Reset but Toggles. It is vastly more precise especially allowing it to Trim where as the other does corrects any adjustments you make and yoyos up/down lots!
As a bonus use Auto-Thrust too for Formation flying as well as obviously for Refuelling.
Who knew it would be the Russians who would take the phrase " hit the brakes and they'll fly right by" so seriously? Thanks, Tom Cruiski !
As far as I know, in real world scenario, Russian pilots claimed that they also use Cobra maneuver to basically notch the incoming missile... don't know how it works, but it makes sense on theory 🤔 but I don't think is modeled in dcs
That would be interesting yes.
It doesn't work by the very definition because during all very high AoA maneuvers, like i.e. cobra, plane doesn't change it's flight vector in relation to opponent's radar - only nose position. For the radar plane fly identically as before the maneuver. It can be useful in other situations thought, like forcing overshot.
Cheers
@@bazej1080 guess you are right. I can't find the video in which the pilot explains it. But it was something related with low speed threshold of the radars(if this is a thing). If the object is too slow the radar ignore it as an error. Don't know 😕 maybe I am talking bull**** but it is an interesting idea to check. Cheers
@@velizarzdravkov6686 if you change your speed enough while changing direction you can reach speeds within the doppler filter faster with a cobra
Viewers should be advised there is less than accurate use of the word "stall" in this video. The stall point is the critical angle of attack. If a wing is actually stalled, increasing the AOA will not increase lift, it will reduce it.
Low aspect ratio swept wings have a broad range of increasing buffet often without a clearly discernible stall break like a straight wing. If going past the AOA limiter increases lift it's because the limiter is set well below the critical angle of attack. I don't know specifics about the MiG-29, but there can be multiple reasons for normally restricting that AOA region in any given aircraft.
The thing is that fighters in general, especially russian ones, have an incredible thrust to weight ratio, to the point that me and my friends jokingly call them "bricks with engines". So with that extra aoa, it shifts the thrust vector a little bit up, and even with less lift from the wing, it can start climbing up, building speed and losing aoa.
@@waltergabriel5501 I don't know what you are trying to say, which appears related to climbing rather than a discussion of when a wing is stalled, but modern fighters are hardly bricks and are very maneuverable.
Side note: MiG-29 is stable with conventional flight controls, but Su-27 is unstable with FBW computer control.
Side note 2: To make very high AoA maneuver like cobra you need to fly very slow, 200-250 knots at most. If not you will do one of two: make loose ~40°-50°ish AoA maneuver or tear the jet apart and lose consciousness in a second.
Cheers and thanks for the video.
Over around 600ish km/h the wings just rip off completely from the flankers if you try to cobra
I have a video Idea. How about breaking the G limit of planes. Might be a bit challenging but I've hit 10.2 Gs on an F-16 before. And it would be amazing someone experienced could try it. Thanks for reading this!
I fly 12g-13g all the time in F-15C :D
@@JZPGod yeah it would be cool if they tried to go as high as they can. A competition on who can pull the highest G's
@@JZPGod
16G is also no problem. And even saw up to 25G Maneuvers.
In an F-15 there is nothing to worry about.
...until ED finally introduces G-Load Damage to it. Eheheue.
Copy Pera
@@grimreapers Nice! Looking forward to see the video when it comes out. Sorry for the late reply man I didn't have internet for a few days!
Thank you for this, I've been trying to figure these things out for a while now.
When I read this title I immediately thought. RC go boomy
Yes. Yes he does.
When talking about the deflection limiter you said you could bounce could someone please elaborate what that means and some of the basic aerodynamics of that? I have never heard of that before.
4:42 XD
Ahhh I took a break from the flanker and forgot about the so
The mig29 still has the CG in front of the CL, the f16 was the first fighter to have the CG behind CL. This is why the SU want to fly backwards.....
MiG-29 is longitudinally stable, unlike Su-27. It doesn't have fly-by-wire and it can't do a Cobra. Still a much better airframe.
thanks! I always wondered why it didn't have the "cobra feature".
@@grimreapers You are welcome. By the way, there is also a version that can do much more than just that, but only because it's equipped with TVC (called "MiG-29 OVT"). Of course, with TVC even a steam locomotive would be able to perform all kinds of maneuvers, so that's not exactly an achievement. The Sukhoi's airframe, on the other hand, is quite a work of aerodynamic art, since not only it can go unstable and flip to around 120° AoA, after that the pressure center will shift downwards and revert the backflipping tendency. That's why maneuvers performed by Draken and MiG-21 cannot be truly considered "Cobras": the planes are always stable during those. Unlike them, Flanker undergoes the unstable/reverse-unstable cycle.
Never good idea loose all speed. Also cause it could be another enemy and if u miss u are fucked up
ACS off - always.
so you dont use the "s" key to pull up the plane?
*Unacceptable, keyboard + mouse gang unite!*
No RC=Boom?
how we send sugestions?
ive heard if you pull the highest AOA in the MiG-21Bis it will do something similar to a cobra, ive tested this on war thunder and my buddy did a similar thing in dcs but i want to see you do it
I have tried this in DCS, but I can't get 21 do it. I don't think that the model supports it.
@@grimreapers I have not tried it, but i think you need to pull some CB to allow the larger deflections at speed. The faster you fly the mig, the less deflection the hydrolic system produces.
@@grimreapers ya my buddy said it wants to do it but the limitations prevent it which kinda sucks
Hi guys I've now got the base DCS world, what controllers would you recommend for a Flight Sim noob who hasn't done it properly since Gunship 2000?
Ive got the Thrustmaster T-Flight HOTAS X ($70ish on Amazon) I just use it with my keyboard and I love it!
Im pretty sure Cap has a vid about his setup, but iirc he's got one o' them pretty-penny Warthog HOTAS Thrustmasters ($300+)
Youre gonna want throttle control, so I would definitely recommend hotas for sure, but its all about how much you wanna spend.
@@OHNOKite I want to be to have some semblance of control over the aircraft
@@mpainter22 if you want to spend a bit then you can proceed with T16000m set with throttles and pedals, I found it to be an excellent starter for flight sims, it gives you that cockpit feeling with HOTAS config, but if you want to spend even less you can go for Logitech extreme 3D, that's got only the stick but its a sturdy one which usually lasts for an extended period. It all depends how much you are willing to spend, which indirectly depends on how much are you actually into real flight sim like DCS. Give it a thought if you feel you really can spend hours in DCS without getting bored then straight away you can go for the big setups. Anyways, I hope you enjoy your DCS world.
@@mpainter22 I'll recommend the Thrustmaster T-Flight hotas X then.
My favorite thing to do in DCS is fly low altitude in the SU-33, doing cobras around buildings and trees like a crazy person.
That flight stick hasn't let me down yet!
@@OHNOKite doest it have programmable buttons etc?
Your head is missing 6:38
mind if i ask whats the max speed that i can pull a cobra in the su27 cause at least at 600 its wings rip apart
max 450 is ok, if you go over it then basically you wont be able to pull that sharp
Try Cobra while flying JF-17
jf 17 cant do it
Yeah the Jf-17 won't perform a cobra but it does have some decent AOA.
JF-17 can;t really do it, at least not like a flanker/Draken.
Deka had made an easter egg before that can do this. You can check their official forum for detailed steps.
@@Mrv9019 I knew it can't but I was not sure
Did you guys use Y while measuring turn rates?
Whats Y?
@@grimreapers
He means the Stick Limiter Override. By Standard it is set as "Y" Key.
Advised would be to bind it to Joystick.
Do a Draken Cobra!
?
@@SteviePonder123 th-cam.com/video/jqiDEcfSnXs/w-d-xo.html
Do a Wheelie Burn!
Draken is not available in DCS.
@@hoilst we don't have a draken
get som!
Dont use the override over 800km/h that will broke your wings.
Not only that but the plane will begin to shake violently and oscillate out of control even if you are flying in a straight line and not touching the controls.
