Trying to build my first plane. I've got Mk1 cockpit and liquid fuel fuselage. I can attach wings Type C or Swept Wings. I can put a J-20 Juno basic jet engine on the back. How can I attach an air intake? I only have a Small Circular Intake. There are no attachment points on the wings or fuselage. Only way I can figure out is to use a Modular Girder Segment on the wing and attach the air intake to that. Pretty ugly and heavy. I see a lot of pictures of things stuck on wings, but when I move it all over the wing it never wants to stick. I've tried turning off the angle snap but doesn't make any difference.
