[Bug]Auto-pilot and ACLS problems with MS Sidewinder FFB2 stick.

[JupiterJoe]

 Bug: Use of FFB stick affects auto-pilot and ACLS.

 Can I reproduce it 100%: Yes

 If not 100%, how often out of 10: 9

 How to reproduce/ description:

 Engage ACLS and/or Auto-pilot.

 F-14 frequently not able to sustain level flight with ALT HOLD engaged.  Track shows pitching up to 50+ degrees without any player control input.  ACLS shuts off and aircraft pitches down once AP ref button pushed.

I have sometimes found taxiing through another aircraft's wake can break FFB.   Time compression has also caused problems.  A restart is necessary to get FFB functioning as it should.

Ground Track does not seem t work properly either.

Version: 2.9.5.55918 M/T

Peripherals: 

Joystick: Microsoft Sidewinder FFB2 

Throttle: Virpil Controls T-50 CM3

Head-tracker: 

Third-party Track IR

Mission File:  Instant Action:  F-14A Carrier Quals - Marianas.

Track: See attached.

Please compare two tracks, with and without FFB sticks.

It should also be noted that FFB ceases to work properly if you switch aircraft. A full restart is required.

ACLS test with ffb.trk auto throttle test no ffb.trk

Workaround:  Deselecting 'Use FFB Trim Implementation' in the F-14's Special Menu enables ACLS to work as it should.  A shame because realism is sacrificed.  Perhaps HB and/or ED will find a fix in future.  It should be noted that auto-pilot behaviour remains erratic with FFB.

A big thank you to @scommander2 for pointing me in the right direction.
