• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Longer Starter time ?

Hi everyone !

I am currently working on my Huey Project and I can’t seem to figure out How to get a longer stating time after switching the starter button …

As of now it is instant and the rotor blades start turning immediately.. there is no time for the starter sound file to be played …

Does any of you have an idea of how to change that ?
I am using the default DA62 engine config with slight modifications.

looking forward to reading your ideas !
Cheers

Taog
 
The sim has always assumed there was a quick starter.

normalized_starter_torque=0.8

and

starter_time=0.5

are the main variables but you can't program a slow build up with these.

You can try

shaft_torque_tc=2

which may affect how long it takes to get the starter going. I haven't tried it myself.

For custom starters I have captured any engine start key events and written my own code to rotate the prop. Then at the appropriate time I can send the starter command and let the sim starter system take over.
 
Thank you Anthony :)

I didn't see your reply,

So I tried that and now my starter time is wayyyy longer (which is good) but unfortunately the Auto start function (ctrl+e) is not working anymore as it only holds the starter switch for 15 seconds and the amount of time required would be more around 50 seconds of holding it....

I don't know how to fix that!
