• 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.

Probably a Noob Question

I have been working for some time to enhance panels in my aircraft, and at this time I am building a new panel for an Adam Aircraft A500. where I have run into trouble is that the Adam A500 uses counter-rotating props and in using the "engine_rotation= 1,-1" line in the aircraft.cfg to get that result (canceling out P-Factor), has made my Prop2 RPM a negative value. I dabble a little bit in XML, but am by no means a programmer. In the gauge I am modifying I found the lines that reference the prop RPM display, however nothing that I have tried will convert it from the negative value to the positive. Any suggestions?

Thanks
 
NVM.. I figured it out.... pretty silly really, I just added the numeric operation to Multiply the result by -1 as such:

((A:prop2 RPM, revolutions per minute))

to

(A:prop2 RPM, revolutions per minute) -1 *)

must have been the fresh cup of coffee to figure that one out, lol.
 
I know it's a bit late, but another thing to try is look at the DC3 tach gauges which monitor engine rpm instead of prop rpm.

The Baron gauge (I'm guessing the one you used as an example) monitors "PropX RPM" where the DC3 tach monitors "General eng rpm:X". The engine RPM values aren't affected by the prop rotation switch in the aircraft.cfg.

That might be a little more useable to your application...unless the Adam you're working on is a "geared" engine/prop (like a Cessna 175) where the prop and engine RPMs values are different.
