To make this as simple as possible, tape some pieces of 8 1/2 x 11 or 1/4 inch square graph paper together then draw a thrust line and out line. Here are a few pictures. This is where it is fun because you can come up with your own "design" pretty quickly. We prefer a slight taper at the back before the vertical fin. Generally the area above and below are as shown for relatively neutral rudder to elevator coupling. Do a similar paper construction template for the wings as well. You can draw trusses in (vertical first then diagonal). Plot out where you want the servos and mark those spots. You may be able to see from the drawings if not I'll see if I can get some closeup shots. Of course if you have CAD, you can develop it on CAD, but in the spirit of simplicity, paper and pencil is the most direct and quickest route to that end.
