This has been posted as a historical question already.Slats by Wotan

Since patch 42 the slats on the 109 and 110 have become very stiff on horizontal maneuvers. This seems like a bug as they were no where near this in previous patches.

Slats make the Me's very unstable now. Everytime one of the slats deploys it snaprolls the plane a bit. Since they deploy allot the planes have become unflyable in combat.
Are they supposed to do that?

Well Dutchie,
I think that is the real question. I dont know if this is a bug or that HT made changes to the slats because of historical purposes.

If this is historical, well EWWWWWW

Me 109 pilots said the slats, when deploying made the plane very unstable because they moved out with a great speed, this was often a problem when they were about to fire while in a turning fight with an enemy plane as, while they turn behind him, they sometimes got into the slip stream from the nmy plane, the slip stream made the slats deploy unexpectedly and threw the aim off.

IMO they seem to be moving in an out a bit too much though, maybe? Even when in a quite stable turn they move in and out and it is almost hard to get by the area where they move and settle in a steady turn.

Wilbus could you please post a source for the slats making the plane unstable...

I posted data in the other threads in that a lot pilots liked the slats. They state that they "slammed" open but not that they snap rolled the plane. Most issues sited are aileron biting and notching back of the elevators as the slats deployed.

Most of the slat issues were related to the 109e.

I have searched for a few hours through my books and on the web.

Anyone try the la7 or La5 or 262?

Please check the link I provided in the other thread.

Try going verticle and wing over back in, the slats pop open and flip the ac over. I cant imagine designing a plne with such a feature as that. Plus there are times where the slats open and close rapidly causing the plane to yaw about...

Even the slats in IL2 and wwiiol dont cause any of what we see here. But what do I know. Thats why I satrted the thread in the A and V forum.

My bad Helvik,
I just figured it a "over correction" done in this patch.

Bump for the Love of Willy!:cool:

Now that is what I think it should not do. They open and close rapidly, it is sometimes even difficult to get past the "line" where they deploy and retract because they do it so much.

Wotan, I never said they made them go into a snap roll. I said the pilots that WHEN they opened they opened quite hard and could throw ones aim off a bit, perfectly understandable IMO.

Wether I can actually find the source again or not I can't promiss, been some time since I read it.

Hi!

By no means im an expert or something, but I have read too somewhere that there were pilots the didnt like the fact that the slats would pop open and thus throw off their aim because they didnt pop open both at the same time. This gives, off course, a rolling movement.

But, AFAIK this was only with the earlier versions, later ones had slats that were connected and thus would not throw the aim off that much, as they were either both deployed or both not deployed.

Could that be or am i totally off?

Purzel · « **Reply #9 on:** June 13, 2004, 04:54:32 AM »

I have just tested it offline:

The La5, La7, 109G10, 110G2 have slats, and they are all unconnected to each other. The pop open independently.

This explains why the aim is driven off when the slats pop open on the 109, if your not coordinated one pops open earlier.

Was it this way in RL?

Flying 110 I definitely noticed "slat" operation... jiggled the nose side to side in a turn...

Wilbus · « **Reply #11 on:** June 13, 2004, 05:06:00 AM »

The fat that they snap roll the plane somewhat is not strange Wotan, not is it strange that they open independently as the speed of the upper wing and the lower wing in a turn are different. The real questions is wether they should open and shut as much as they do, sometimes they seem to go crazy and pop open and close several times a second, that is what makes it difficult to get past it and get into a stable turn.

One link I foud quite quickly, it is not this link I was talking about before but here too they comment on the slats "throwing off the aim" of 109 pilots if they deployed in the critical moment.

It is IMO not weird that they would do that as they change the aerodynamics of the plane somewhat, and they deploy very fast and with a heavy bang and force, they should definatly affect the plane.

Very interesting link Wil!

ok now ive tried it, yes the slats are "broken" in AHII...

i missed a recording chance but more than once last night i had each slat coming out on its own, flicking back in which caused the other to flick out....that would flick in....and errr you know, the other one came out. This WASNT with that high AOA either....

it also seems you cant keep them out... IE the turns i do, even if they are the same force on the stick with no slippage cause the slats to keep going in and out, sometimes in random orders.

Ch1: WTG overlag on evasives there, couldnt hit ya
me: no, that was just my 109 going nuts

B41 was "right" B42 is just wrong......
