Hello Everyone,

I'm using FSX 737-800NGX, there is a problem on yoke's stab trim switches that are not working and also how do i program those switches in fsuipc? 

thanks in advance.

Fsuipc has an option „elev trim up/dn“ in the button assignments. 

I don‘t think that the switches move in the model anyway.

They don't move, but I assure you, when you press the trim hotkey or switch on the joystick, it still works. yoke trim animation missing most likely due to fsx limitations back in 2011 when the NGX was released

Yup, I have assigned all my yoke, throttle and joystick buttons via FSUIPC... works without any issues with PMDG, one just has to make sure to take care that the aircraft specific option is enabled prior making any changes.

Thanks Ephedrin for response.

Oh! I have to use elev trim up/ dn for yoke, what about disengage AP? i'm searching actual control for yoke trim in fsuipc because i read, yoke's trim Disengage AP first then trim in real aircraft.

Thanks again for help

Do not use trim when A/P is engaged.  Using trim to disengage A/P is not the correct way to do so.  There is a separate PMDG keycommand option for A/P disengage.  See the Introduction document and also look in  PMDG Options > Keycommands

Thanks Downscc for your response.

Below is the reference video of Mentour Pilot. he speaks about yoke's trim switches.

What he's saying (correctly) is that if you make a trim input whilst the autopilot is engaged, the autopilot will disengage.

He is not saying that is the correct, routine way to disengage the autopilot - quite the opposite, in fact.

Thanks skelsey for your response.

your'r right, he is not saying that is correct or incorrect. I got it...I have another question is there ATC and interphone offset in PMDG to assign joystick buttons?

I appreciate your response or help.
