• 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.

MSFS 'RatedRpm' 'MOI'(in MS2020 Helicopter)

Hi Everyone
I am new here, but not to flying.
In MS2020 in the Flight_Model.CFG, [MAINROTOR} section is 'RatedRpm'.
It doesn't seem to do anything. My goal is to adjust the Rotor RPM, to a correct value. So, if this does not do that, is it a calculated value based on Engine parameters or governor settings?
I have searched already and found nothing to explain.

Also is there a rule of thumb for setting a blade MOI? It seems the have a dramatic effect upon handling characteristics, so basing other settings upon a faulty base setting, gets out of hand quick.\

Thanks
Stu

Hi Stu, can you provide a little more background? What rotor RPM, any?

Actually, no. In fact, there are no rules of thumb for helicopter development beyond "Asobo prefers airplanes." Most developers appear to control their RPM with governor settings, are you developing something?

Hi Rick
Thanks for reponding. Main rotor RPM is what I want to adjust. I am a helicopter pilot, and in a previous life Engineering background. I am working my way through various models and fixing (to my satisfaction) various handling quirks. I have been sharing some of my findings with one developer. I want realism, he is realistic about the clients, and allows some tolerance in that regard. Generally, I can fix a lot of the 'workarounds' that I am seeing. Rotor Rpm has me stumped.
I am basically substituting as many known's into the Flight_Model.cfg and Engines.cfg, and getting it to perform as it should. Having good sucess on most attempts.

I see. I am currently developing a rotorcraft that is further beyond the pale than even a helicopter, with tandem intermeshing rotors.

And yet, here we are. Is that where the sharing of your discoveries ends? Because I'm already starting to wonder who the guy is, I have my guesses.

I don't know which one of the laughing emojis conveys, "I get it, all in good fun," so I'll just type it instead.

Rick. I just had a look at your project. Wow. I am super impressed. Hopefully SU15 helps you out, and doesn't undo too much work that you have done.

Haha, thanks so much. I've been given the impression by people who supposedly know the new version will unlock functionality that this and most projects will be easily scalable to. After all, modeling is modeling and everything else is just throwing code at the wall and seeing what sticks, right?

Thanks! I won't know what to do with myself if I ever get it all buttoned up.
