This process is very easy to do but is causing some confusion since some guys have not seen it done yet. Once you see it done your hand will hit the forehead and you will owe me one beer!

You need the following tools.
long straight edge.
Low tack masking tape
sharpie Ultra fine tip marker, the big ones put out too much ink and can soak through the tape and damage the finish
Step #1 Mount your stab, elevator control horns, elevator hinges, and Elevator servo with the control horn. Everything must be mounted up and ready to go. Use masking tape to hole elevators in trail at zero with stabs.
Step #2 we are going to project the servo horn location to the side of the fuse.
a) using masking tape and eye ball the tape in place vertically on the side of the fuse. Use the edge of the tape as your straight line.
b) Measure the depth from a fixed point to the servo connection. Not the servo arm screw but where you will connect to the servo wheel. In the photo my system is already installed to show you what it will look like.
c) transfer this depth measurement to the masking tape and I place a horizontal segment of tape to help this marker. You can use more masking tape, and a sharpie thin tip marker....Or you can play it a little loose and use the intersections of the tape as your cross hair.
