Minor nitpick, your list is missing "SA 342 Minigun" ;)

If I recall, you also need to make sure the runway your trying to use is the active one.

"radio switch works as ptt" is a setting you enable in SRS.

Could this be the reason for your issue? Also: are they going off in a random direction, or towards Bx9?

Keep in mind that the minigun version has no camera, so the co-pilot will have less to do.

The minigun is on a new variant, so you'll need to use the mission editor.

Did you remember to turn on the Master Arm switch?

When in autohover and co-pilot seat the flight axis controls the camera.

It's not bindable by default. You need to go into DCS World\Mods\aircraft\AV8BNA\Input\AV8BNA\keyboard\default.lua (or "joystick" if you want to bind it to joystick) And add the following: {down = fcs_commands.Switch_ANTISKID, cockpit_device_id=devices.FLIGHTCONTROLS,value_down=0.0,name='Anti-Skid off',category='shortcuts'}, {down = fcs_commands.Switch_ANTISKID, cockpit_device_id=devices.FLIGHTCONTROLS,value_down=0.5,name='Anti-Skid on',category='shortcuts'},

How many targets are you shooting at?

Also make sure your textures are not set to low, or else some hud elements may be missing.

Here's a screenshot of the setting.

"Normal/IR View Toggle"

Have you tried the AG-Undesignate/nws button?

I seem to recall there being an indicator for rpm % on the engine display page.

Have you tried binding a button to "Throttle cutoff" and holding that while moving the throttle back?

I'm not 100% sure, but have you tried AG undesignate?

According to https://updates.digitalcombatsimulator.com/ release and beta are both on the same version now, though... So it seems they did push an update to release as well.

The ssl cert from updates.digitalcombatsimulator.com is expired, and is preventing the updater from updating dcs.

I think you need to double-press the SSS down to select the TGP. At least that seems to make it work somewhat consistently for me.

I'm not sure you're supposed to use "manual fuel" in normal operation.

The pickle button is called "Bomb Pickle" and for the gun is called "Trigger" both are in the HOTAS section.

Did you have valb or std selected?

Have you checked if any of the tings posted here (link) helps?
