[EVALUATING] 1.2.10.32275 (openbeta) FFB + Trim

[Eldur]

Coming back here every other patch (and I skip some) feels like doing this endlessly:

 

 

At the beginning it's still fun to do some reporting to get things fixed, but in the end it gets boring if it doesn't pay off even after years...

 

 

Trim is just totally oversensitive if applied twice due to using two different techniques to model it at the same time

Not so sure this is a bug. Just different systems in different planes

The mig21 does not have Fly By Wire, the Su27 does.

 

So maybe the Mig21 is physically linked to the elevator and you can't trim the elevator without moving the stick too.

This isn't a problem unless you are trimming the plane while resisting the trim at the same time. Why would you do that? Just let the stick move as you trim the plane. It may be impossible to resist the trim moving the stick in the real mig21.

 

The su 27 is FBW so the stick is not actually connected to the surfaces.

 

As for the Mig15 and the Sabre. The Mig has pre stall shuddering because the stick is physically connected to the tail surfaces but the sabre has hydraulics and a semi flying tail and the aerodynamic forces do not go backward to the stick. no prestall shudder. These different systems may not behave the same with trim.

 

I still don't really see why I would trim the plane and simultaneously hold the stick still so it can't move with the trim. I just loosen my grip a little and let the stick move as I trim.

 

I'll test this though. I love the FFb differences between the different types of planes and their different control solutions.

Problem still there for DCS 1.5.4.55169 open beta

 

The virtual control stick and the FFB stick are disconnected. The FFB stick does not represent the position of the virtual stick.

 

Please LNS!!! Take the 4 minutes to watch the video I previously posted in post #21.

 

The Mig-21 has neither trim tabs or a fully moveable tailplane. Therefore trim is effected by changing the neutral position of the elevators themselves. Yes in real life this reduces control authority (adding back trim has the same effect on the control surfaces as pulling the stick back. As the position of the stick directly reflects the position of the control surfaces the stick will move as you trim.

 

No fully moveable tailplane? How is this called?

 

 

Your last two sentences tell, why the current FFB function of the MiG-21 is NOT correct.

 

Look at the video I posted.

Noone is talking about Fly-by-wire. I´m sorry, but you don´t understand the problem.

The trim moves the stick, both the virtual one and the FFB stick. So far so good.

But there is a mismatch between the position of the FFB stick and the virtual ingame stick, as soon as you trim. When you trim fully to one endposition, you cannot center the virtual controls anymore with the real FFB stick.
