Best Practice to Reduce Weight

I'm done with creating a table model of an airplane.  Now I'd like to create the same model of an airplane to be flown as an RC plane.  I did some research and found a couple of airplane design that has successfully been tested and flown.  Here's one of the examples that I found for free created by a company called Eclipson. 


One of the front parts of the fuselage.

I converted the STL file into a slicer program called Simplify3D.

and test print just to see how it ended up look like. 

So I can't really figure out how they draw their skin for the fuselage in order to keep the weight at the bare minimum.  From the slicer perspective, it looks like if you keep the thickness of the fuselage skin to below 1-2mm, the slicer will create a 1 layer for the outside and 2 layers for the inside print and the skin comes out at 1-2 mm but empty in between the slicer which keeps the fuselage lighter.  That's my speculation.  Any thought or advice or best practice when designing something like an RC plane in order to keep the weight as low as possible?  I hope my question makes some sense.  I'm attaching one of the STL files for reference.  Thought?
