Pitch trim on P39 is not functioning.

[453=Thornley]

Hi Gents

 

The pitch trim on the P39 is not functioning when force feedback is selected. 

 

With force feedback on and using a Logitech G940, I can't adjust pitch trim the P39 at all. 

 

As an experiment, If you get the P39 to fly straight, level and hands free (120mph - Water 60%, Oil 40%, Mixture 75%, Pitch 75%, Throttle 45%), then adjusted the pitch trim from 100% to -100% and back to 100%, nothing will happened. The P39 will just stay exactly where it is, cruising straight and level at 120mph. 

 

Now if you turn force feedback off, suddenly the trim works perfectly with the aircraft trimmable over a wide range of speeds.

I second this.  Same issue.  Many aircraft are untrimmable when using force feedback (MS Sidewinder FF 2 for me).  The P-39 requires significant forward stick to maintain level flight when using force feedback.

Seconded, only for the P-39 as far as I know though. I did the tests : I can pitch trim, it will be visible on the plane's aileron, but no effect on the flight as long as I keep FFB ticked in the settings. If I untick it, I very clearly see that the plane is responding on pitch trim. (Don't make the change on the fly, it will not always take the setting change into account, so to test it, re-load a QMB with the option unticked.)

 

Need more tests on other planes to check if the problem is there for those also.

So, after a bit more test, it appears that the issue is for many planes. Hoping for a quick hotfix from our fantastic devs here  as it's kinda problematic, from several perspectives (tiredness, immersiveness, realism of course, performance, etc..)

The Axis planes stabilizers aren't concerned yet, only the Russian trim. Time to go deeper into that lovely 109 G6..

In my game, P39 is trimmable from stick a little fordwad to stick full fordward. I land whith trim full nose down and I still need to push the stick a little fordward. I also use Logitech G940 with force feedback. In  the rest of the planes I have no trouble.
