After startup and throttle application, saw typical excessive deflection, reset rudder servo arm two splines forward to "over-center" rudder - favoring a little right, flew the airplane for several minutes and noticed a tendency to turn left, landed and saw usual left rudder/nose gear indication.

Decided the airplane can't continue to be flown this way - especially for instruction - so set about removal and inspection of the rudder servo gear train as suggested.

A pallet knife slid only deep enough along the servo cavity to cut through the RTV and free up the sides of the servo, then using a small pry bar to lift, not pry the servo up out of the cavity resulted in a nice, clean extraction. The RTV-like adhesive smells like Chinese model aviation; using an X-Acto blade to slice the adhesive at the corners permits access to the screws on the servo case. Inspection of the gear train showed no broken teeth that I could find.

I'm going to try flying the airplane with a Hitec standard HS-422 substitute that fits the existing cavity well and appears at cursory inspection to be more stable so far.
