How are you guys handling the >4 engine planes?

Not sure If this helps, but I thought I would pass this one on.

 

Not one SECOND in that video mentioned throttles lol!

My solution to control all the Latécoère (6) and the “Dornier Do X” (12) engines with a 4 throttle controller.

I defined the 4 lever axes in FSUIPC7 and then put the following modified script into the fsuipc7.exe folder.

Create and use an MSFS controller config with the throttles removed for the Latecoere and Dornier X.

Many thanks to the person who sent me the original code. Note: the script doesn’t work with the Hercules for some reason, I use SPAD.neXt for the Hercules.

 

--=====================================

 

--    File Throttle.lua
    
--    Put this file to the FSUIPC folder that contains the FSUIPC.ini file
    
--    Add the file name to the [AUTO] section of the .ini file like this
    
    --    [AUTO]
    --    1=lua throttle

    --    or (make sure numbering is consistent if the AUTO section already has entries)

    --    [AUTO]
    --    1=lua xyz1
    --    2=lua xyz2
    --    3=lua throttle

I have to resort to doing a binding in MSFS rather than FSUIPC where one axis controls all four engines.  I tried a few times to use FSUIPC to bind the left axis to engines 1&2 and the right axis to 3&4 without success on the bae-146.

What is the procedure? If you don't mind. Thanks

[Sonosusto 715]

I use all 4 jet throttles for the bae146. More fun that way for me

I have the bravo and use two throttle levers, so two engines on each lever.  

Exactly what I do, I have the Flightsim Factory Handles \ Lever set, since I fly the Airbus quite a lot and my lazy side kicks in, so I duplicated (modify) my Fenix Bravo Profile in MSFS for the Just Flight BAE146 (I like to fly this lately, since the update). For the 146, the 2 throttle lever setup works fine for me. Actually makes it easier to sync the 4 engines (I know, I'm cheating)😉

[solito 65]

I use a CH Throttle Quadrant, and works great at 4 engines aircraft (DC6, B747, A340,etc)

Also reversers work OK for the 4 engines
