RE: CJM F-4D Conversion and Build
Next, it is time to cut the wing servo boxes. Again, this trick was learned on Bob Tube. I used 1/16 ply wood to build the servo cover and its box. Basically, the servo cover is built using 1/16" ply and caped with 1/16" ply pieces on top of a 1/8" ply with the center removed. I then installed the servo box cover on to the wing.
Oh, forgot about the hinges, sorry no pictures, but the wings and Flap/Ailerons are also hinged.
