I've no experience with that brand of servo. However, I use mostly Futaba or Hitec, I have many Futaba 148's that have literly hundreds if not a thousand or more flights on a 1/4 scale bipe before any signs of a problem. Finally the aileron servos did start to jitter a bit and when I took them apart, the pot wipers had acutally worn a grove through the conducting material on the pot. I consider that a very long lived grup of servos that served me well. I doubt many servos ever get that long a life. The only other servo failures I've evr had in some 50 years of modeling is gear failure and that was usually due to shock loads in a crash or other mechanical mishap that was no fault of the servos.
