It's not a recent video, but it's really very up-2-date, and there's plenty of interesting info.

The video makes part of an excellent series of videos by totoritko, the tallented developer behind the CL 650 and the TBM 900, two of the Best Ever addons released for X-Plane, and I'd be tempted to say, the CL 650 being actually the most advanced, in all sorts of ways, aircraft model ever built for this flight simulation platform.

Worth watching if you're curious about the inner details of X-plane's FDM.

Good video. “Tokorito”, the presenter, is the lead designer of the marvelous HotStart Challenger 650.

I am going to make a slight correction to your post. The YouTube URL should be embedded as a link, so it can be directly clicked on to take you to the video.

Very interesting video, thanks.

This gives a glimpse into how much more is going on than whether or not we have transparent coastlines in the simulator.

It's a complex beast for such a relatively small team.

He and those like him are genius wizards.

I will also add, partly because of the fuss about negativity but mostly because it's true, that this goes for any platform. 3rd party dev is obviously not a cake walk.

And, FM documentation is where LR fails. The M$ SDK actually presents their conservation equations with quite a few details on how things work. The only details we get from Austin come in his descriptions of features in blog posts. We get little to no mathematical explanations from him. I think the only details we can see are related to how to use Planemaker and a list of datarefs. Boooo LR! ; )

I dont understand that EVERY thread ends in a comparison to MS  🤮

@blingthinger go to MS and went happy.

You're right, ans sorry for me bringing it :-/

 

Hahahaha! Such quick posters with such negativity. I brought it up partly because of the thread that just got shut down. They claim negativity. So I try to see what happens when they get praised. Don't worry pretty little heads: I won't mention M$ again in this thread!

Let me be more specific on the most important thing here:

ALL 3rd party devs that dig into flight modeling and aircraft systems are impressive talent. Doesn't matter what platform you are on. Anyone who says otherwise is closed-minded who just needs to be entertained all the time.

Also, I do want to see more math from Austin!

Oh and another question. Tokorito said that he doesn't use xfoil for transonic. Now, I know in planemaker airfoils are only specified as function of Reynolds number, not Mach...but xfoil does go up to mach=0.99 in the freestream. Wonder why did he say it doesn't go beyond 0.5?
