How do you change the log-level?

FGRUN. I set it to warn. Want me to change it?

Or else,
--log-level=warn

I figured it out, thanks.
I'm not getting any of those errors. Is it stopping the aircraft from loading?

Well, it crashes, because it can't read the FDM.
I'm using your github, btw. Maybe I should use FGADDON, see if it makes a difference?

Another thread suggests the only soloution is clearing flightgear.org. Trying that now.

Edit:
Did not work!

Sorry I am just now replying, for some reason I didn't get your new post grouped in "new posts".

Can you try loading it using the command line instead of fgrun?
If you need help with command line let me know.

Yes, I would also try the fgaddon version. But also try any of them completely isolated form the others if possible.

Oh, what version of FG are you using?

Do you still have a previous version of the aircraft?
Or, at least, a previous version of the FDM?
(by checking that the JSBSim FDM filename = J3Cub.xml and this in J3Cub-main.xml are the same).

don't forget to be sensitive with the case in the names... winwhatever is not case sensitive but other OSes are very much case SenSiTiVe...

I'm a bit confused who the last two post point to. Me or @legoboyvdlp? As this appears to be a cache or version conflict issue local to @legoboyvdlp's system, no? Either no one else is flying this model or it is working for everyone but @legoboyvdlp.
@legoboyvdlp, do you have other versions in your fgrun list/paths that might be causing conflicts?

my post is in addition to dany's which i think is a reply to lego...


[aside] this is where selective quoting comes into play but i've been trying to play by the forum rules and not quote things "because it is just right up there" [/aside]

My post was in response to legoboyvdlp.
Sorry, I hadn't understood where the issue came from.

Sorry, I hadn't understood where the issue came from.

No worries, I just wanted some clarification in case I am missing something. I don't know for sure what this is and what is at fault so all input is welcome.

FYI: I pushed some more refinements to the hydro system for the J3Cub and PA-18.

Water rudders now add drag when in the water.
Water rudder have more influence on turning speed and radius, you can now turn in the water sharply when the rudders are down.
Amphibious gear add drag in the aerodynamic FDM when extended.
The pontoon drag in the water is IMO is tuned really well. From the real life videos I have seen, our hydro simulation closely mimics RL. I am incredibly happy with it. :D
Following are a couple videos demonstrating the newly tuned hydro effects.

Test run.
