"Hollow" Loft for Front of RC Helicopter

Hey everyone!  First time posting this forum, and I could use your help!


I just presented my thesis this past week, and am set to graduate in just about a week.  Only one thing holding me back, my final project for a CAD course I took as an elective.

For my final project, I've been modeling an RC helicopter (picture attached).  I've been able to get through almost the entire helicopter, but the last component left is giving me some issues (the shield on the front of the helicopter).  Anyway, I've put some work into getting things set up, and I could some suggestions.


To begin, I created two 2D sketches of the part, and basically connected these two sketches using splines in a bunch of different planes.  After this, I went ahead and used the loft command, and out popped a solid ugly-looking helicopter shield.  I definitely understand that breaking down the part into more and more planes would help to make this loft look more accurate, but before doing so, I am wondering what the best approach is to "hollowing out" the solid created.  As you can see from the attached pictures, the shield is not solid, but rather wraps around the inner workings of the helicopter itself.


Hope this makes sense in text, but please use the attached pictures to get a better sense of what is going on if I've confused you.


Thanks in advance for the help,
