Hummingbird Posted January 1, 2017 Share Posted January 1, 2017 One thing I find strange about the FM in 1.5.5 is the inability to exceed a relatively low AoA at higher subsonic speeds, as if I'm being held back by a flight computer which limits the amount of pitch moment I can apply.

BadHabit Posted January 1, 2017 Author Share Posted January 1, 2017 I m not expert but i thing that its normal at high speeds you always need to trim it down for level flight. An airframe that would have tendency to pitch down on high sub speeds would be a bad thing. Else you are experiencing something else i dont get. Happy new year!

Hummingbird Posted January 2, 2017 Share Posted January 2, 2017 No it's not about trim, it's solely speed related. I can leave the trim alone and the problem will still remain. In short I can't put the aircraft into an accelerated stall at speeds where I definitely should be able to. This didn't use to be so. There's something very weird going on with the AoA range of this aircraft atm. Link to comment Share on other sites More sharing options...
BadHabit Posted January 3, 2017 Author Share Posted January 3, 2017 Ok I saw what you are talking about. It is an extreme pull up on subsonic speeds, has nothing to do with what I was talking about. I noticed also the same behave with the M2K.

Frederf Posted January 3, 2017 Share Posted January 3, 2017 Depending on the tail surface ratio controller setting beyond ~0.95-1.1M you cannot reach 33° on UUA-1 because the tail surface is at maximum deflection before this value is reached. Beyond ~1.2M accelerated stall is not possible as the tail surface at max deflection (even with manual APY set to most sensitive) produces less than a stalling AOA.

My problem that this is occuring already at 750 kmh TAS where max true AoA is ~12, and I'm not able to reach the critical AoA (which is currently a very low 15-16 deg) until speed drops to 600 kmh TAS - the AoA gradually increasing from ~12 to ~16 as speed drops from 750 to 600 kmh, max stick deflection all the way.

UVPMechan Posted January 6, 2017 Share Posted January 6, 2017 FM for Mig-21 is very bad. This is also confirmed by former pilots of the aircraft. Cradling at low speed during landing, plus a small axelerace during afterburner. It's a degradation of the aircraft. Link to comment Share on other sites More sharing options...

Pocket Sized Posted January 6, 2017 Share Posted January 6, 2017 My problem that this is occuring already at 750 kmh TAS where max true AoA is ~12, and I'm not able to reach the critical AoA (which is currently a very low 15-16 deg) until speed drops to 600 kmh TAS - the AoA gradually increasing from ~12 to ~16 as speed drops from 750 to 600 kmh, max stick deflection all the way. That's the pitch ratio changer, it keeps pitch response from being too sensitive at high speeds. It's not perfect though so at some speeds it will limit your turning radius. If this is realistic or not, I don't know. DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.

humptydumpty Posted January 6, 2017 Share Posted January 6, 2017 Doesn't concern the topic issue but there seems to be a problem with the RSBN too, the RSBN auto changes the channel. So i am going to stop flying the Mig :( till things are sorted out.

Frederf Posted January 7, 2017 Share Posted January 7, 2017 RSBN auto changing? That's not something that I've ever seen. Is it possible a keyboard or joystick binding is changing the channel? I've looked but I can't find an official source on the APY transmission ratio scheduling except just by what is printed on the gauge face. Link to comment Share on other sites More sharing options...

shab249 Posted January 7, 2017 Share Posted January 7, 2017 The MiG-21 may currently overperform in sustained turn rate. We are looking into it. And also please fix the gun pod box Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
zaelu Posted January 7, 2017 Share Posted January 7, 2017 Hi, guys... quick interjection here. Thrust to weight has nothing to do with sustained turn rate. simple. HUH? (that is an interjection not 2 paragraphs of text ;) ) Thrust to weight isn't just the number you get when you divide thrust to weight? like 10kg thrust devided to 10kg weight you get the number 1.0 The thrust to weight is normally defined at mil power or full AB etc but basically it is just the division of thrust at some point by the weight at that point. So basically I can vary the thrust... by just reducing throttle for example and since the weight decreases slowly (because of fuel burn or ammo release) that T/W ratio will decrease per pilot input if we want. So what your statement say is that sustained turn rate has nothing to do and is not influenced if you simply cut off the engine altogether. I don't think is like that. So maybe you shouldn't underline that word "nothing" if it's used only as a figure of speech.

humptydumpty Posted January 8, 2017 Share Posted January 8, 2017 I just can't seem to land her anymore, she rocks and then wham, i am usually around 300-320 for a touchdown b4 that the rocking starts. Not sure why. I have my curves set to 25 for roll using an extended 2 feet stick. Could that be an issue ?

BadHabit Posted August 31, 2017 Author Share Posted August 31, 2017 (edited) ${1} In this video among others, we can see the main problem that the Mig-21 has "among others". Very stiff controls and sensitive control surfaces. Move the stick 1% the aircraft starts banking which gives no time for corrections. Curvatures don't really matter since the in pit stick-control surfaces movement is instant. The stick in-cockpit should have a travel range before control surfaces respond depending on speed and etc. Take a look at T/O And in flight and Hope this stuff we trigger some movement in the devs team. I see ppl flying this thing nowadays like a boat which is normal since the modeling of the stick to surfaces system is so damn wrong. PEACE!
