1. Detail showing motor stick and mounts.  Also shows mounted motor.  Mounted this way, motor can be removed easily as it's held in place by a single servo screw.  See also Motor Mount. 9. Here, receiver is simply taped in place on bottom of plane.  Note "shorty" antenna to keep things clean.
2. Be sure to center each servo by hooking it up to your radio before you permanently install them in your plane. You can't reposition the servo arms once installed. 10. ESC is also taped in place on bottom of plane.
3. Using a Sharpie "Ultra Fine Point" marker, draw an outline of your servo for the rudder cut-out.  Position rear of servo about 1/8" forward of wing trailing edge. 11. R/C-56 Canopy Glue works well for gluing the control horns in place.
4. Cut the servo opening with a sharp #11 X-Acto. 12. Your CG (center of gravity) should be in the area shown.
5. Trial fit your servo into the opening.    
6. Servos are easily secured with low-temp hot-glue.  You can easily remove by slicing glue with an X-acto if necessary.    
7. Elevon servo glued in place and hooked up.  Shown here using Dubro Micro EZ Link for connecting pushrod to servo arm.    
8. Here's a view of all three servos in place.  Note that wing has been slotted for servo wires to pass through to bottom of plane.
