The wing landing gear bays are simple white card stock with no rendering ( I just don't have the time or desire to Photoshop a detailed version ).
basically take a section of approximate proportion and bend, trim and fit in the area of the spar where the door cut out will be.
cut out the doors from the wing bottom ( put a thick card inside to prevent the blade cutting thru the upper wing skin ). Keep the doors for later on.
dry fit and trim as many times as you need.
glue the wings in place.
here is a view of the gear bay.
