Engine Performance

Grunf,

 

Here it is. Hope your system is good because I did this with heavy clouds where I get only 10 fps :)

 

If you could check my start up too that would be awesome.

I think it could be due to inlet cone position

[grunf]

It seems that the track doesn't play correctly (known DCS bug). I never saw you takeoff, during your takeoff run at ~300km/h you put the throttle to idle, go to the grass and explode. :D I guess that's not how it happened.

 

Could you do another track, with a simple mission, just your plane, and all the default settings (weather, time of day etc)?

 

Your cone seems fine.

 

As for the startup procedure, you should wait for the engine to spool up to idle before turning on the systems. Also turn on the gyros before the systems that depend on them. You don't need to turn on the emergency converter (next to the gyros).

 

You forgot to turn on the aileron booster (in front of the throttle), and put the flaps into the takeoff position.

 

You may also want to turn on the pitot heat and set dangerous altitude warning (both located behind the stick).

Thanks for watching the track , will try and create a new one .

 

The few things I didn't turn ON was just because I was too lazy . Like the Booster and the pitot heat etc..

 

But appreciate your info on all these.

 

Stdby let me create a new track. But I won't do the manual start will leave it to auto start.

 

BTW I didn't the throttle went to idle on its own. this does not happen on the F-15 or the 109 / 190.

Bloody hell now it's not happening I tried 5 times all ok strange. Nor did reboot or reset my controls

Strange indeed. :D

[humptydumpty]

Strange indeed. :D

 

Yes strange and strange enough that again she is not picking up the nose below 400 km/h maybe this is something gotta to do with the pitch axis curvature I think I did increase it.

[humptydumpty]

Can anyone suggest good curve settings ? I find she has a slight bounce on pitch and I don't know if it should be that.

 

MY PITCH / ROLL / YAW curves and deadzones.

 

Pitch : Deadone 3 - Curves 25

 

Roll : Deadone 3 - Curves 25

 

Yaw : Deadone 3 - Curves 25

 

I kept them same but could be different I don't know. There are no deadzones in a real aircraft

 

Advice appreciated.

[humptydumpty]

Any suggestions for the curves above especially the Pitch ?

 

I am using Logitech Attack 3

[humptydumpty]

I am still losing engine RPM and the weird thing I notice is only during pitch control this is so funny, I don't think I am doing anything wrong with the Mig.

Hi ironmaiden,

 

it is still very likely that you are flying the aircraft at or near 0g conditions and thus stalling the engine. Make sure to keep an eye on your G-Meter at all times.

Hi Cobra ,

 

No i am not flying her at 0g , because it was happening during take off and the engine was not shutting down it was just going to idle and I could see the throttle going to idle :) and I had to keep adjusting the throttle, well it turned out to be a very stupid issue in DCS axis settings there were two throttles being assigned so I made the changes and don't know why there were two throttles.

 

The funny part was it was not happening every time I flew her.

 

I will check tonight if the issue persists.

[humptydumpty]

why does she keeping banking to the right ? my controls are all centered, I am not if there is a aileron trim for her , i will check,

[Golo]

No aileron trim on 21, and this effect was discussed before too, tho I dont recall any conclusion on the subject.

Thanks Golo.
