@bspboy just do
calculateDrag=false
No more drag!
But drag moves to other parts

Be aware though, using fuselage on the wings causes lots of drag.

Look here, used multiple parts for wings, plus built up the individual control surfaces as well and made them move with rotators. The Overload and Fine Tuner mods really help as well...I had to use Overload to get the sweep at the right angle ("offset"), so recommend you get those for your operating system.

Once you've figured out how to use fuse pieces to "build up" wing shapes on top of the actual wing surfaces, you'll see that many also "build up" control surfaces, i.e., aileron, elevator, rudder, flaps. The way that's done is to deselect the control surfaces from your wings and stabs in the options menu (just press the red "X") and use entire wings as ailerons, elevators, etc. Cover those with fuse parts as well and attach the parts with rotators.

Put a fuselage in the center of the wing, then flip is 90 degrees horizontally. If the wing is long, make sure the end pointing to the plane is thick, (.50, .75, or 1.0) for better visual and physical quality. Then, match the end closest to the end of the fuselage to the length of the wing. If the wing is too thick and a little bit is left, you can put the fuselage forwards. Now you have two options. You can either: one, put another fuselage down, or leave the space there for flaps. Now add a section on the end of that fuselage, witch, if was made to match the wing properly, would equal 5.0 in length, depending on the wing scale. Add section, then continue the process of matching the wings. Don't be afraid to use rise and run, too!

I you want check out my besra, just make the fuselage pieces sub-assemblies

thanks this is really gonna help me make some sleek aerodynamic planes

If it does not go that far, use multiple blocks

yes ive been told to edit the fuselage block but it doesnt seem to want to go that far.
