Ryan STA-M. No room on the rudder. All is basically hidden inside. Lots of working room inside to do this. Thanks for the tip though.

One question I do have though: the tail servos are side by side (two elev, one rudder--rudder is the p-p). Because I don't have (and don't want to get) a servo reverser, I have to put one of the elev clevis' on the same side as the other (so they rotate in the same direction but operate opposite to each other). Because of that side switch, the control rod is right under and real close to the rudder arm.

What I want to do is put a 1/16" strip of balsa front and back of the rudder servo so it is lifted up by a 1/16" so the elev control arm will clear the rudder servo.

Is that a good idea to lift the servo up so that there is a bit of extra clearance? It would be a level front-and-back lift up, sort of like when you put a washer under the rear bolts of an engine to give it a bit of down thrust as needed, only this would be both front and back of the servo.
