Elevators Bouncing Around Erratically When Using Extreme Pitch Up/Down on Joystick

When I use my Joystick (Thrustmaster T.16000M FCS) for extreme pitch up/down; the elevator on tail of plane bounces around erratically making aircraft unstable. Only occurs when joystick is pushed forward or pulled back to an extreme position; where joystick is say in its last 20% of its travel range full back or full forward.

This problem occurs with both F14 and F18 which are the modules I use.

If I ease the joystick back to a more moderate position away from the more extreme positions the problem goes away. Seems worse particularly with pitch up more so than with pitch down.

I know the problem is not with my Joystick (Thrustmaster T.16000M FCS) as I have two of these.

One is brand new and the other one is about 12 months old. The problem occurs on both joysticks. If I go to the Thrustmaster Control Panel (image attached) and test the pitch up down axis; the centre cross within the Axes is absolutely stable and does not behave erratically at all with joystick in any position.

I do not have any conflicts within controls settings for pitch axis.

Problem seems to have started with latest DCS Open Beta 2.5.5.33184.

I do not think this is normal behaviour unless there is something I just do not understand. Or maybe it is just a bug that DCS need to sort out.

Any suggestions would be appreciated...thx...Gary

p.s. Have noticed after further gameplay that pitch trim function does not appear to be working either. Though this is only a problem with F18

Is “FFB” by any chance selected in Options?

Force Feedback is disabled. Problem occurs with/without Force Feedback being enabled.

Have attached a couple of Track Files demonstrating the problem when I do a pitch up loop in F18.

Initially I do not do an extreme pull back of joystick to its maximum range; but then I do and then the problem can be seen in the video. The problem is much worse in pull up rather than push down of pitch.

Also use a Thrustmaster TWCS Throttle Controller which has a mini joystick and the same problem occurs with that device too

Strangely as mentioned in previous post; pitch trim for F18 does not work either...both are pitch related issues...Gary

p.s. I do not have any Mods

Watched your tracks and my impression is that it's the FCS moving the stick. I thought initially that it was to ensure that you didn't exceed the citical AoA but, in looking closer, the movement actually increases your AoA to 30-31° rather than reducing it every time it happens. I don't think it's a bug. It seems purposeful to me. You might try asking for an explanation in the FA-18 forum.
