I notice that the only way for the elevator trim to work is to hold a key up or down. If I toggle the key for fine,incremental control, nothing happens.

Is this a bug or have I overlooked something in the settings?

Holding a trim button is the way it works in many aircraft as well. Are you finding that holding the button down "a sec or so" (rather than just a quick push and release) results in too much of a trim change? Or maybe there is only one trim increment per button push even if the button is held down? I happen to use FSUIPC7 which lets you set a trim button to just about whatever 'increment' you want. In my case, I have it set up so the trim increment is quite small for the first 2 secs I hold the trim button (useful for small changes or high speed), and then the trim increment increases if the button is continued to be held (useful for large changes or  low speed). The button does automatic repeat when held.

Would you be so kind and attach a picture of the fsupic setting, please.

Actually the trim movement amount should be liniar, instant without any delay at the same rate. What i noticed as you mention, there is a delay of 1 x 2 seconds before you see the trim wheel moving. All the airplanes I flew and fly as soon as I touch the rockers there is an instant displacement on the index.

Anyhow, I noticed this issue from day one, if it is a setting on FSUPIC to adjust I would appreciate the info.

Thank you!

Yes, I agree, as far as I know electric trim movement in the real world is linear (although the real a/c I flew did not have electric trim  🙁  ) . However, given some of the limitations in the sim, and the fact we are using a wide range of a/c types, I find the multispeed trim I set up convenient for my needs -- to each his own.

I do not notice a significant delay when I activate the elevator trim in the sim. The pic below shows how to set up the basic trim increment using FSUIPC  (this is NOT the multispeed trim setup which also requires the use of a small Lua script).

Here, button 2 on controller Y has been setup to activate Down elevator trim. Offset 0x0BCO is the FSUIPC location that hold the trim values that nominally go from -16383 to +16383. Negative values are nose down trim, and positive values are nose up trim. The 128 value is the increment (change) with each button push (or button repeat if the button is held). In this case we are setting up a nose down "increment" since we have selected Offset Sword Decrement in the Control sent when button pushed window. The -16383 in the Parameter window sets the lower limit.

To assign a different button to Up trim, we would select Offset Sword Increment in the Control sent when button pushed window and have no sign in the Parameter window indicating 16383 is the upper limit.

So in this case assuming we have used an increment of 128 for both Down and Up trim, we have divided the total trim range (from -16383 to +16383) into 256 steps (32768/128). Note in the above the Control to repeat while held box is checked.  Using 256 or 512 for the increment would give you a coarser trim, and likewise, using 64 or 32 for the increment a finer trim.

There is more information in the FSUIPC User's Guide around page 27 (search for Offset Increment/Decrement Controls).

Al,

Thank you so much, your help is greatly appreciated!

Of course a trim wheel which is an axis instead of buttons works best. You can use the Sensitivities page to make the trim behave like you want it to. You can't really set sensitivit y curves on buttons like you can on an axis. $80. But the $100 dollar one has a horizontal axis too and some toggles. I use the large 2705. Mounted in a heavy cardboard box weighted with 3 ounce fishing weights and velcro on the bottom of the box so the box is a very solid mount.

There are other brands of these, some more expensive than this one.
