Strange roll oscillations

I have been trying to learn how to dogfight in the Bf-109 and it has been a real struggle. It seems that I easily enter into a rolling oscillation (despite holding my controls steady) making it impossible to turn with a P-51D. I have been keeping my speed above 300km/h so I have no idea what I am doing wrong. It gets so bad at some points that I can get no response from the controls. Does anyone have some suggestions on what I am doing wrong?

Same here. Sugest from some Kurfurst Aces are always welcome :)

Check the settings for BF109 in misc options.. the auto rudder, aileron.. etc.

I don't imply I'm a ace or smth :)

i have the same issue with the new patchversion.

as far as i see it, its a matter of "clean flying" ... means - keep the ball centred.

sometimes and in certain flightattitudes you even have to "over-rudder" a little to stay "on rails" and be able to get the shot.

take these advices from a somewhat "slightly above average" 109driver :pilotfly:

Sounds like you might be pulling too hard and stalling.

Sadly they removed the warning buffet in 1.5.4 so it's kinda guesswork figuring out how hard you can pull before she starts rolling.

I would agree with the stalling but the way it oscillates is almost like a loose aileron flapping around and less like a stall.

I confirmed that auto rudder is disabled, and take-off assistance, aileron trim and rudder trim are set to zero.

With confirmed bug of slats being inoperative after latest patch (and God knows what more), I wouldn't pay too much attention to roll behaviour during turns now, as it most likely will drastically change again with the next update in two weeks or so.

Sadly it is pretty much unflyable in this state :(

Did you try checking the deadzones of your joystick? Sometimes spikes in potmeters can cause sudden virtual stick displacements, even if the RL joystick is held steady.

I used CTRL-ENTER to monitor my input and it was rock steady

Make a video and it will probably clear things up if we see it.

I think something is very "fishy" since the latest patch - the 109 is grounded till the next update.

No slats and the overall behavior of the FM feels very weird.

I just installed the Bf109, and first found it almost impossible to fly... As described, ossilating sudden rolls made it realy hard too handle...

Found my issue tho :doh:

Was so eager to get it airborn that i just assigned the most relevant axis and keys to go :pilotfly:

But when i looked, as deffault all my "joysticks" were assignet to the same tasks, therefore my rudder brake pedals was assigned too roll to, instead of left/right brake...

Cleaned up the controll axis chart, and the rolls dissapered :music_whistling:

(Guessing i twinkeled my thoes just now and then, as the problems was'nt consistent )

Now its not impossible, just hard to fly! Didnt try it before the latest patch, but i hope im having the same issues as everyone else, and that the slats and FM will get better on the next uppdate... Could bee me, not suited to fly a Messerschmitt tho :joystick:

I did not have have multiple axis assigned. This was happening without even moving the controls once I entered into the oscillation state.

Does anyone know if the update 1.5.4.57013.162 fixed the issue?

I saw in the notes that "Wing slat will be animated" but does not sound like it did anything to the flight model.

It did.

I tried the previous patch version and it was grim. Latest patch = nice!

I can confirm. I was wondering the same thing and question the "animated" patch note. but its pretty much back to old stability now with working slats.

Awesome! Thanks guys!

Tried it out today as well - behavior of the 109 seems fine again.

Only Thing now to wish for is the Return of the stick shake (FFB)

I just tried it out now and wow what a difference! It will still snap-roll on you if you get the speed down too low but that happens in a predictable way. The strange oscillations are gone. I am wondering if this is simply a placebo or if there was something changed in the flight model somehow.

Afaik working slats are the only difference

The slat change was not just an animation as explained by Yo-Yo here... It was tied to the flight model:

I was able to just reproduce it using version 2.0.3.56503. I don't know if the ver 2.0 Alpha is up to the same baseline as the full release version or not. Track of this is attached. In the track you will see me enter into this strange rolling oscillations and despite my control surfaces being almost static (in a left hand turn but ailerons deflected right, elevators down and rudder almost neutral) this oscillations persist. My velocity also appears pretty steady I think.

2.0 hasn't had an update since the one that 'broke' the slats. I'd assume since it's already fixed in release that it will be fixed in the next 2.0 patch whenever that might be.

I will test again on the release version
