Help with mig 21

[Travis Bickle]

it is really hard to turn and when i get in the air it is impossible to fly it, it just goes off to the side

[Gunfreak]

21 isn't easy to fly. But if its behaving very oddly.
Then do the standard stuff.
Check for double bind on axis, delete any mods you might have. Delte content of meta shader and foxo folders in saved games/dcs.
Do a repair/integrity check.

i have never downloaded any mods, btw can you explain how you properlly turn when taxi and taking off. i tried to read but i dont know what they mean

It's fairly simple, while you're already rolling just press the break lever a bit and turn with your rudder pedals.

Keep in mind that Mig-21 doesn't have a computer adjusting your inputs like the Hornet or Viper. You will need to trim and trim and handfly it and trim. Basically, trim.

Taxi??
You skip important details now half of your comments were lost like you.

On the ground Mig21 steering like WW2 birds.
It use left or right brake to turn.

[Troll Norris]

Mig-21 don't have nose wheel steering system thus you need to use differential braking for turns.
First of all make sure the nose wheel brake is disconnected
To turn fully depress left or right rudder pedal and press the wheel brake paddle. It is better to have the wheel brake pedal assigned to axis because often you don wont to apply the full brakes. The aircraft will start turn and then it will keep turning by its inertia. To stop turning you have to fully deppres counter-pedal and press the wheel brake paddle.

About the flight - In the Mig-21 you generally need to fly fast. (at least 600 kph IAS) Its wings are very small, provides relatively low lift. In turns watch the AoA indicator. Do not exceed the limit of 28 units. Exceeding the 33 units leads to instant stall followed by spin.

TBH the video is full of misinformations. I would not use this one as the guide.

Example: 2:30 - Just go past the idle cutoff detent and leave it there. Not like in the video. Moving throttle forward may cause the engine flooding followed by extreme exhaust gas temperature.

3:18 - Do not power up the emty pylons. It is useless. Also you should not switch the IR/SARH missiles master arm power switch while on ground. It is used as the master arm switch. You should not turn it on on the ground, take off or landing for safety reasons.


3:50 - Not "On/Off". But "On/Stand By". The guy probably don't understand how the radar works. How the vacuum tubes work. You need to keep radar in stand-by mode unless you will have to wait around 5 minutes to heat up the vacuum tubes to the operating temperature. 45 minutes in stand-by is more than enough. It is much longer than usuall flight time is.

About turning - right opposite way. First depress rudder pedals, then press the wheel brake paddle.

6:00 - Wrong. It will not use all hydraulics. It will deplete all compressed air - pneumatics. Not because it tries to raise gears. Because the air powered wheel brakes are applied when the gear lever is in retract position. This causes compressed air leakage.

6:55 - Guy forgot to connect the nose wheel brake for better braking power at take off and landing.

7:40 - It is not warning. It is the passing marker beacon beeping.

9:00 - Those are not jet engines. Those are solid fuel rocket engines.

Well, feel free to omit that video then if Troll says it's so innacurate, I'll add my two cents though:

- the "reverse" way worked for me for a long time, don't remember going out of compressed air, though surely it's more wasteful. Makes for gentler, more controlled turns but can't be used with keyboard shortcuts all that much since they go from 0 to 100%.
Also having watched some Mig-21 Bis on video and some in reality -- it does look to me like they quite often nod first, decreasing speed when on a long stretch of a straight taxiway, and turn a bit later. You know, add break, turn, release break, let it turn, add break, straighten it out, release break.
Sometimes they do it much quicker though, and I'd say at those times they use the reverse of the above in terms of break and rudder - step on the full rudder, add enough break to give you your wanted turn, do the opposite direction to straighten it out.
By logic alone this would be the preferred way to save on air, but I don't know if it's "the one and only sacred way of doing things".

- about that throttle, in the DCS manual: "Move the throttle forward a bit more from IDLE (this is an in-game request due to specific throttle axis mapping)."
Don't know if that's relevant anymore because I haven't had problems not doing that. Can't fault a man for following the ingame manual, though.


Plus, I think he understands how a radar works better than many of us, him being a GCI in RAF back in the day. That was a low blow, Troll, unneeded personal venture, let's say. You can do better than that.
The rest of your points are fair and square.

[Troll Norris]

It is not about to save the air. It is about you don't want to stop moving in turn. Doing it opposite way IMO causes too high aircraft slowdown. I use the brake pressure just right to start turning. I know it is not possible with the keyboard. But doing it this way causes minimal loss of speed. In fact you quite a lot of compressed air. So little bit of wasting is not issue.

[Xupicor]

Never had problems with slowing too much in turn, just need to be delicate with the controls. You can also add a touch of power when turning which in reality, sometimes - judging by ear - might be the case. It might also be an artifact of listening to the engines from afar while they're moving and the whole airframe changes direction, so I'm not so sure about that. But having tried it in game - works fine.

Off to the side? Can you be more descriptive? Provide speeds.

As for taxiing, which is what I assume you mean, the MiG-21 uses compressed air for actuating differential braking.

To turn, apply full rudder deflection in the direction you want to turn. If you want to turn right? Turn full right. Once you do that, apply the brake. You control how tight the turn is with how much brake you apply. So, if it's a shallow turn, tap the brake (assuming you're using a button.) or if it's tight, hold it.

The reason you want to go full rudder in the direction you wish to turn is because you're completely closing the valve in the braking system. If you don't, you bleed the compressed air.

So, remember to always return the gear handle back to the middle position to conserve compressed air.

The MiG-21 is not at all difficult to fly once you accept it does everything fast and has some eccentricities.

Name checks out.
