I think I have found the culprit. The joystick button I use as TMS seems to be a bit capricious especially when I use it for "TMS Forward Long", so sometimes it works and sometimes it doesn't. Thanks to your post I know now that i need to watch for the ""TDC" indication in the bottom left of the HUD. I apologize for reporting a bug while it was poor precision of my VRP stick.

I'm a bit puzzled. You say "the HUD was never set as SPI". Shouldn't it be "SOI" rather than "SPI"? In step 1. I use Coolie switch up short to set the HUD as SOI. Is that the wrong thing to do?

Here is a new track. I replayed it and it showed the real sequence: 1. set HUD as SOI 2. Slave TDC to TVV 3. Manoeuvre the TVV to the target 4. Ground-stabilize the TDC 5. Make SPI 6. Slave all to SPI Up to and including step 5. all was fine. But when I did "China hat forward long" to "slave all to SPI", the little square pointing to the SPI disappears. A-10CII cannot SLAVE ALL TO SPI.trk

wrong. I always set the the SOI (not SPI) to the HUD first. But I don't trust the tracks. Why are you talking about waypoints? When the target is at a waypoint I don't need to go through the process I have described in my original post.

May I correct the correction... The default binding "RWin + C" does not work. But "RShift + C" works fine, and also a game controller button works.

I posted this in January. See https://forum.dcs.world/topic/368442-slave-all-to-spi-fails-most-of-the-time/#elControls_5595989_menu @f-18hornet Replied that this issue was "reported for analysis" and the thread was locked for replies. I have not seen the bug confirmed, and there is still no statement whether and when this will be fixed. In my opinion this is important functionality for designating ground targets. I have successfully used it for a long time, and then an update destroyed it. Not an indication of good software configuration management! The bug fix should be a priority item! ED, please provide an answer!

Unfortunately the problem came back. Apparently the scroll wheel of my old mouse was the culprit. I bought a new one and the problem is gone.

I looked at this and saw that the command is default-bound to "RWin + C". My German keyboard doesn't have a "Right Windows" key, so I bound the command to "RShift + C". I also bound it to a button on my Joystick. Both work fine here.

My added line actually triggers the "Eject" command 3 times with a single button press. Twice when you push the button down, and once when you release the button. This is the LUA line: {down = iCommandPlaneEject, pressed = iCommandPlaneEject, up = iCommandPlaneEject, name = _('Eject (press once)'), category = _('Systems')}, And of course I have all modded "default.lua" files under saved games, using the Command Injector by @Quaggles, so I don't have to mess around after every update. Is "General" a better place than "UI Layer"? I wouldn't know why.

It took me about 15 minutes plus a bit of testing time, to add a line into the "default.lua" for "UI Layer", so it works across all aircraft modules.

My understanding is that the stick smoothing option helps to make stick input less "nervous". I wouldn't think that it helps to "slow" the pitch trim, which is the main subject of this thread. Please correct me if I'm mistaken! My method for providing a slower pitch trim is to add these lines to the "default.lua under "Saved Games" (I use the command injector by @Quaggles): {pressed = iCommandPlaneTrimPitch, up = iCommandPlaneTrimPitch, value_pressed = 0.3, value_up = 0, name = _('Trim - Nose Up Slow(Hat Aft)'), category = {categories.flight_controls, categories.stick}}, {pressed = iCommandPlaneTrimPitch, up = iCommandPlaneTrimPitch, value_pressed = -0.3, value_up = 0, name = _('Trim - Nose Down Slow (Hat Forward)'), category = {categories.flight_controls, categories.stick}}, This methodis very robust.

I found that Heatblur provides 3 different setting speeds ("normal", Fast and Slow) for a number of commands (e.g. "Weapon Slew". I do not believe that the real Phantom has those options, but it helps the sim users. A good reason in my opinion to do the same for the pitch trim command.

I see, you also used the "traditional" format of the .lua lines. That seems to work fine.

Has anybody managed to make this mod work with the F-4E Phantom? I couldn't make it work, and in the end I had to remove the sub-folders for the Phantom under "..\Input Commands\" because it blocked the DCS software completely. Heatblur uses a different structure in its "default.lua" files and I suspect that the @Quaggles mod doesn't handle that correctly. Edit: I also didn't see anything for the F-4E on the Github page owned by @Munkwolf. @Munkwolf do you intend to provide bindings for the Phantom? Edit: I seem to make progress, using the "traditional" format in the "default.lua" under Saved Games. Example: I wanted to make "slow" versions of the Pitch Trim Nose-up and Nose-down commands. The original command lines have this form: { name = _('Trim - Nose Up (Hat Aft)'), up = iCommandPlaneTrimPitch, pressed = iCommandPlaneTrimPitch, value_up = 0, value_pressed = 1, category = { categories.flight_controls, categories.stick, categories.essentials } }, { name = _('Trim - Nose Down (Hat Forward)'), up = iCommandPlaneTrimPitch, pressed = iCommandPlaneTrimPitch, value_up = 0, value_pressed = -1, category = { categories.flight_controls, categories.stick, categories.essentials } }, In the original "default.lua" (under "keyboard") I could use these modified lines and they worked fine: { name = _('Trim - Nose Up Slow (Hat Aft)'), up = iCommandPlaneTrimPitch, pressed = iCommandPlaneTrimPitch, value_up = 0, value_pressed = 0.3, category = { categories.flight_controls, categories.stick, categories.essentials } }, { name = _('Trim - Nose Down Slow (Hat Forward)'), up = iCommandPlaneTrimPitch, pressed = iCommandPlaneTrimPitch, value_up = 0, value_pressed = -0.3, category = { categories.flight_controls, categories.stick, categories.essentials } }, But when I used these lines under "Input Commands" in "Saved Games", DCS World stopped running when I opened Options/Controls or tried to run a mission with the Phantom. So now I used the traditional command line format under Saved Games: {pressed = iCommandPlaneTrimPitch, up = iCommandPlaneTrimPitch, value_pressed = 0.3, value_up = 0, name = _('Trim - Nose Up Slow(Hat Aft)'), category = {categories.flight_controls, categories.stick}}, {pressed = iCommandPlaneTrimPitch, up = iCommandPlaneTrimPitch, value_pressed = -0.3, value_up = 0, name = _('Trim - Nose Down Slow (Hat Forward)'), category = {categories.flight_controls, categories.stick}}, I entered these lines under "C:\Users\MyName\Saved Games\DCS\InputCommands\F-4E\Input\F-4E-Pilot\joystick.

Interesting reading! I struggle with the pitch control not only for the trim, but also for the response to stick movements which, to me, appear very "nervous". These "large oscillations" don't help when I try to aim at something. So I added "slow" pitch trim commands to my "default.lua" with pitch trim response values reduced from 1.0 to 0.3. Will see how that works for me.
