Wings should not be a problem as there are holes in each rib and the wing tube provides an exit for the air.

The elevator, however, will need the same needle holes. Rather than TE, you can also make a hole in the CA hinge cut; you should have a small hole in the center anyway to help CA flow so just push it all the way through to help air flow too.

The ailerons are the worst because making a hole it a little harder given how thick the sections are; again use the CA hinge locations to help.
