• 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.

Hello all,

I just want to show my latest project, the Learjet 85

This project has been going on for a while now, due to a lot of problems but so far I think it looks decent.

What do you all think ?

Quality work, but what about all your other started aircraft. Ever thought of finishing them in some form (AI, exterior model)?

This one I am going to finish for sure and the other models are just not good enough to me I've learn't so much in the past year that the other models are just not on par with what I do now :P
 
Very nice, Osian! That thing has some big engines. Looks like competition for the Gulfstream and Citation X.

Thanks!

It sadly will never enter real production because Bombardier canceled it, only two prototypes were produced.

The MD-80 you've started could very well be the base for a new AI model.
And if you prefer to do exterior models only, you should really consider getting into the AI business. All you'd need is some lower polygon LOD models and AI flight dynamics. Or offering the models to AI developer teams for the flight dynamics. Just let as little of your efforts go to waste as possible.

The MD-80 was the first ever project I did so it really isn't good.
And I do prefer to do exterior models only but than in a Project Airbus / TDS/Posky kind of way, although I do plan to make a VC for the Lear85

Be prepared to devote a lot of time to the VC, my friend. VC's are easily the most frustrating things to model in 3D (FS-related, anyway) especially when they need to be as close as possible in dimensions to the real thing.

Don't expect your first attempt to flow straight into the final product. It almost never works out that way. My first VC was trash, and the second one seemed great to me at first, but as time goes on you notice more and more things that could have been done better. Before long you've already re-done everything. This is the issue I've been facing since getting into this hobby.

My advice is to read up on techniques and take it one piece at a time, absorbing information like a sponge. It's something you just have to keep working at to become proficient in. Took me almost 2 years to get my cockpit where I wanted it...And it's still far from perfect.
 
I agree with Ozzy. Now I have advanced with my T.5, I get really really really ashamed for my D.21. It's a big heap of trash, in some respect.

But of course Osian, keep going on ;) I might advise you though, to trying understand how mesh works. That's especially applicable to your Landing Gear Doors problem you posted here.

To be honest, the model you post in this thread looks very good, I like it, so keep going on this one! Oh, and for the time being, first focus on control surfaces before getting to more complicated parts such as the Landing Gear. If I were you, I'd also re-address the vertical tail. Do you have some photographs of this one? I might be able to give you some advice.

That's how your tail should be, I think:

It's been a quickie, but the starting point is how the VTP (Vertical Tail Plane) leading edge flows into the 'roof' of the scoop. This can be seen on photographs rather than on a three-view drawing.
I made it as follows:
- Assumed a symmectrical 0009 profile, but any symmetrical profile will do.
- Made the vertical tailplane without the scoop, so basically two airfoil sections (tip and root) and interconnected.
- Then make a cut somewhere above where the scoop should be (loop cut, Ctrl R).
- Make the leading edge of that part perpendicular to the leading edge line of the VTP.
- Remove the leading edge faces below the oblique part.
- In the DUTCH verlengde /DUTCH of the oblique LE part, place the 3D cursor.
- Then select all vertices of the oblique part and perform a 'Spin' operation on these (-70 degrees probably).
- Then finish the scoop.
- Connect the transistion curve loops to the loops of the VTP, first in longitudinal direction then in vertical direction.

Eventually, the mesh exists of only two tris: on the LH and RH side of the scoop where the transition curve meets the VTP root. Of course, the eventual mesh exists only of tris, but the way quads are aligned makes or breaks the mesh.

Hope this helps!

Cheers, Daan

Nice work Daan.

Have you tried Hinge Extrude?

Hi Bill, thank you! No, didn't use that, but remember it's Blender. The Spin function basically extrudes a number of vertices around the 3D cursor for a certain angle and a certain number of intersections:

Pretty useful, as are lots of other Blender functions!
 
Wow thanks for the tips :) I will definitely redo the vertical stabilizer the current one is pretty much a place holder now :P
 
I worked on the LJ 85 for two years....it was going to be a great airframe, but Lear tried to go "Bombardier" on it and eventually it had to end, to the point where Learjet is no more.

With this model there isn't a lot of documentation out there, and no performance data, so you can benefit a lot from doubt. :-)
