[NO BUG] Bf109K-4 defect module?


Little_D

Recommended Posts

Hi gents,

 

i still have this damn problem with the 109. After take off, flapps in, gear in, trim nose down at max, ATA 1.2 by 2000 rpm and speed 250km/H, when i center my x52 the 109 starts climbing like hell into a looping. I fly with no curves on the controls. My squadmades dont have the problem, there 109`s take the nose a little bit down and rolle to the left a little bit, thats all both have also trim nose down to max.

 

In the 190 i dont have the problem, after take off, flaps in, gear in, trimm to zero position, the 190 take the nose a little bit down and roll to the left a little bit when i center my x52.

 

With the 109 behavior i have in the moment no clean control in the speedrange from 220Km/H - 350 Km/H as she will allways starts climbing like hell. When i reach 380Km/H - 400Km/H all is fine and she behaves like she should.

 

I reinstall and repair DCS, but nothing change.

 

Can somebody help me, please?

 

regards

Hi Razo+r,

 

thx for the info, so its a known bug or problem?

I did also some tests, it doesent matter if i take off with flaps or without, i have it all the time, even after 20 minutes of flight, when i go into a trurnfight

as soonest i come into the speedrange of 220 Km/H - 350 KM/H i get this fu.... nose up looping climb, trim is alltime nose down to max, as the 109 is non

flyable for me without trim max down.

 

If this is the real behavior, than they should killed the constructor of the Bf109K-4

Hi Darkraiderss,

 

yes my boys and me fly allways with 100% fuel, but fuel is not the problem, as i wrote, that my squadmambers dont have this problem, even with 100% fuel.

Interestingly enough, I have the same problem with the Spitfire. Could there be a common solution?

Do you change PITCH trim setting to neutral before take-off or do not?

Spitfire has preset trim to TAIL HEAVY when spawns.

Hi gents,

 

my pitch axis is defoult ingame, no curves, no limits in x or y axis sensetive, i have only set the deathzone to 2. Also in the controll check of my x52 the pitch and all other axis are centert and ok, they move as they should and go back to neutral as they should. Before i take off i trimm to max tail havy, than back to zero and than full trimm nose down and back to neutral to check the trimm. After that i trimm as i wrote to max nose havy and let it there, as i cant fly the 109 without max nose trimm. Also when i check all axis ingame in the settings they move as they should.

 

On the other side, the FW190 i take off and fly with trimm at zero all the time and the FW190 is at all speeds easy to fly and handle, no crazy nose up and looping climb and i fly here also only with 100% fuel.

 

regards

DCS 109 is known for requirement of nose-down trim for level flight at cruise speeds and a bit of stick push for high speeds, but... full nose-down trim at 250 km/h doesn't sound right, and never happened before, unless something got glitched in 1.5.6 and 2.0.5 versions (I haven't flown that plane in either of these two)?

Don't think you have different 109 then all other, the Pitch up tendendy for the 109 below 300-250 Km/h is here as it should be. But Flying below 250 Km/h have at all only negativ aspects,

the 109 starts to pull up to slip and drop the wing the constant turn speed is also heavy affected.

I Fly with no curves and death zones at all, have constant trim from zero to +1 to increase the pull up moment of the Ruder at high speeds.

 

Take off with +1 and set the Flaps to second Mark, the Flaps shift the COG foward for gently take off.

But you have also to get used push the Stick foward to contary the nose pitch up when you get to slow.

Once you have tasted Flight, you will forever walk the Earth with your Eyes turned Skyward.

Hi Art-J,

 

you are right and it is also known from me, but as you said at this low speeds it is not right. i have to fly with trimm set to 2 nose down, so full trimm nose down. The funny thing is, at speeds about 380Km/H - up to max speed, she flys like i know here from all other WW2 sims, nice and easy. Also i find here more maneuverable than all other 109 from all sims i flown at high speeds, pitch at about 750Km/H is as easy to handle as at 400 Km/H, i can pull here easy out of a steep dive at 750Km/H without need to tuch the trimm and hold here nice and soft close to blackout. I have this problem since i bought here.

Hi MAD-MM,

 

sorry to sai this, but i dont think you get my problem. How you can sai i should use trimm +1, when i have with trimm set to +2 at speeds from 220 Km/H - 350 Km/H the problem, that the 109 is climbing into a looping, when i center the stick!!! I have no problem that the K-4 is tail havy, she should be like this, but for high speeds from 400 Km/H up to max speed, not for start ore landing speeds, makes no sence at all. I would understand this behavior also if i would take of with max power and MW50 on, that the 109 would climb at 220Km/H into the sky, but not with cruise settings.

 

Also i did a test to start without flaps, after weels up with a speed from 180 Km/H and weels in at 200 Km/H with ATA 1.2 and rpm 2000 i have to pull the stick forward to fly straight or make a shallow climb. when i center the stick after take of over the runway at 210 Km/H she goes with 20 degrees+ into a steep climb. When i reduce to rpm`s about 1700, than i get the behavior my squadmembers have and what is logical for me, when they center the stick after weels in, flaps in, at ATA 1.2 by 2000 rpm`s at 220Km/H. there 109`s take a little bit the nose down and roll to the left. When they dont tuch the stick she went in a low left hand easy nose down turn and they have also the trimm set to +2. Also i testet my older x52 from my son, i still have the same problems. Also my squadmabers that take off with me in formation and watch the behavior of my 109

are saying, that someting is not right here, when they see me climbing like hell into the sky, that they need to pull the stick hard back to follow me and i have my stick centert.

 

Sometimes i have the feeling, that the trimm is not working right, even when ingame in the cockpit it shows the right numbers. Doesent matters, if i use buttons or the weel from the x52 throttle.

Complet reinstall and repair of DCS is allready done 2 times, no changes.

 

regards

Move in to options axis tune,

turn on slider and set the curvature to +1

 

This have the effect to push the virtual stick all the time a bit forward.

 

So easy is that :thumbup:

 

Hi Jafferson,

 

you are my hero :thumbup:!!! It works perfect.

 

Only 2 test take offs needed to feel and see the difference. Can you explain me why it works with setting to slider, but not as normal joystick in 109 with 2 different sticks from the same company and on the 190 the normal joystick works perfect? Or is it a DCS miracle?

Maybe this is a stupid question, did you try CTRL + ENTER in the game to check how your axis behaves in the game and where your virtual stick is positioned?

FFB joystick will really help.. I quit using the X55 as soon as I got a Sidewinder FFB2. I recommend you do the same. I have another one for spare.. :)

Hi OnlyforDCS,

 

yes i did and the funny thing is, when the stick is centert it shows it also centert in the window, same goes for the trimm, rudder and ailerons. But i still get this crazy nose up looping climb. It works only with slider and there it shows the stick in pitch a little bit forward and than it works, i will ask my squadmades how there window look when the take off and come in the "bad" speedrange.

I can fly hands free with trim +1, little bit less without full fuel and ammo and such. Seems to be fine with me, only time its a little crazy is air starts before you get it tweaked to where you need it.

Is that with the MW50 tank empty too?

 

Just curious if the whole pitch up issue has just been badly explained, so people are using it by default in an unstable configuration.

For example the P-51D is right nightmare to fly if you brim it and use the rear tank, but there's a dedicated section in the manual about it.

 

Wonder if the K-4 just needs a couple of CoG diagrams and explanations...

I did two tests, one full load, 50% fuel, no ammo and no MW50. Trim was slightly different for each, like either side of +1. but hands free is possible in pitch axis.

 

Remember as well, its not ideal to trim level anyways, the 109 performs better in high speed dives with the slight nose up attitude. Honestly I dont even notice it anymore.

Slider for stabilizer trim: only 70% of range used

 

On a related note, I use the slider on my TM Warthog throttle to set the stabilizer trim. This makes sense to me as the true aircraft uses something similar in the form of a wheel, and it works much better for me than a toggle switch.

However, the Bf-109 module only uses about 70% of the slider range. In other words, I reach max. nose-heavy trim when the slider is only about 70% forward. So when I set the slider to its center position the trim is already fairly tail-heavy. In my opinion this is not how the axis control should work. It should use the full range of the slider to go from max. tail-heavy to max. nose-heavy.

I believe that it worked that way before version 1.5.

In my opinion this is a bug.

Note: I have not set any curvature, deadband or custom curve

Edit: I hoped I could tweak it in the clickabledata.lua but that doesn't even contain an axis control (element of type default_axis or similar) for the trimwheel. Strange!

Yes it's true, the same here. The max forward is 70% in my axis. I used a Saitek Throttle Quadrant for the test.

Yes, same result with the left throttle of my TM WH. The issue is clearly caused by rhe Bf-109 implementation.
