PMDG Nose down trim no longer works

[Boeing_Driver 76]

Anyone notice this happening? It happened before I updated to PMDG's latest version but it persists after the new installation too.

 

I've tried assigning nose down trim to something else but nothing budges it.

Nose up still works as always.

Quick guessing:  Are you tried push and mantain your yoke and then use TRIM DOWN function ?

I'm not sure what you mean by push and maintain. However, the nose up trim works fine with the plane parked (or flying) and without any manipulation of the yoke. The nose down trim, under the same circumstances, does not work at all anymore.

move your yoke at a forward position and hold, then try to use TRIM DOWN.

Why does everyone say PMDG as if its an aircraft type, I guess you mean some variant of the PMDG 737 and not the DC6?

I wonder how many different aircraft types they would have to release before this odd habit stopped

I don't know whether this is related to the OP's trim problem. But the PMDG 700 series has been porpoising -- bouncing up and down in flight from end to end -- since the SU11 beta was released. And, again, I don't know whether this trim issue is caused by changes within the SU11 beta or perhaps by something PMDG changed.

You don't have to push the yoke to trim down.  You cannot be pulling opposite the way you trim; there's a cutoff switch in the column that will activate if you do that. 

Also, there's a limit to how far the main electric trim can run nose down in the 73; it's around 4.1 units. To trim down farther than that, you need to operate the wheel manually (with the mouse.)

If it's not those things, then I don't know. I've done a few flights with it since the latest update and trim works fine here.

Silly question perhaps but have you checked your down trim binding to ensure it did not get disconnected or changed somehow?

Sorry folks--my bad. This was due to a hardware issue.
