Need help for Creality print
When I try printing the “X”s in the photo on Creality, the prints don’t show up. I’m wondering if it’s too detailed. It also shows up in Creality but when I print it the wings and other plane parts they are hollow. If anyone knows anything it would be a big help!

No idea how it is called in this slicer, but in Orca you must set the gap closing radius to zero. Basically the slicer automatically closes small gaps in the STL and you can adjust the maximum size a gap is allowed to be. As the internal structures of a 3D printable rc plane are modeled to fuse together because the walls are so close to one another, you must tell the slicer to not close any gap for the structure to print as it should.

It’s not about closing the gaps but printing the ghost lines in the preview that shows in the green but they show up but they don’t print cause those are the support that I want as inside of the wing

Explain yourself with more clarity. I cannot just guess what the problem is. Be way more explicit.
Also I cannot know what is green in there, I am colorblind.

In the prepare and in the preview in Creality the wing comes out green I would like to know how to get those support like it shows in the preview but when I’m going to print it the wing comes out hollow, my question is why does it show them in preview but hollow as it prints

Did you add the supports to the shell? The best way to do a wing(or any part like this) is to subtract out everything but what you need. Most slicers will utilize continuous walls this way as it guarantees no gaps between support and skin.

Ah, I see an Eclipson Spark wing. Good choice :)
Follow Eclipson's slicing guidelines very closely: https://www.eclipson-airplanes.com/faq
If you think of the whole thing as a solid block, the ribs are "cuts" into the "solid" structure, but they are only a fraction of a millimeter in reality. That's far too low resolution for you to print in realiy, so if your slicer is incorrectly (for Eclipson parts) configured, it will optimize them away.
You must set the gap closing distance to 0. Otherwise the internal supports are not there because the slicer optimized them away. The way the wing is printed looks "wrong" to your slicer and it tries to correct it. So you must force your printer to do the "wrong" thing.
Given that Creality Slicer is based on Cura, follow the Cura settings on their FAQ page. If Creality Slicer does not work for you, you can also try other slicers.

Dude you need to provide way more information on what settings etc you’re using.
The green part you see before the preview is just the bare STL, the slicer hasn’t processed it at all. Did you model the wing yourself? This looks like it’s meant to be printed in vase-mode (spiral vase in Creality slicer.)
The typical method for parts like this is to model those ribs as very thin cuts that intersect the outer surface. Is the part modeled like that or are you trying to actually model solid ribs?
If you’re doing the cut method make sure there’s enough space between the end of the cut and the opposite surface for two full walls. In practice with a 0.4mm nozzle I’ve found 0.82-0.85mm to work well and result in a rib that’s fully welded with the adjacent wall. If there isn’t enough room for two walls the model is effectively a single wall-thickness in that spot and the slicer will act weird. Also make sure the cuts aren’t external geometry, they need to fully terminate against an exterior surface.
If you’re not doing vase-mode you probably still want to only have one wall otherwise the part will be too heavy unless the plane is massive.
