Servo boxes
I'm not going into too much detail here. Cut out and sand the servo box in the wing. make it nice and squared.
make the servo box out of 1/16" light balsa. It only has to be about an inch tall/deep, don't go crazy here. just glue it up and drop it in, or drop it in sides first then glue the ends...whatever works. let dry and sand fluch. Add rails of your choice.
As for the servo lead hole, not a big deal. get a long piece of 1/2" tubing. sharpened, and run it through the hole at the servo box. take care to go straight toward the box or you could end up cutting through the skin or worse. But don't panic, I've done a ton of them and they all came out fine. just take your time. Go in a few inches, pull it out and clear the foam from the tube. Check alignment, repeat until it comes out inside the servo box.
One thing of note" The servo box is about 13" deep, and at the time all I could find was 12" tube. I bought 2 pieces and one size smaller that slipped right inside, CA'd it together and voila. Extra long servo hole tube cutting thingy.
