I started flying single channel in the mid '50's, & i still have a Matador Midas 10channel reed outfit with 5 Bonner duramite servo's, that still work. Over the years i must have used several hundreds if not thousands of servos. This is the first time i have ever heard of 'Breaking or running in' of servos, & have never ever done it, never heard of anyone doing it, nor been instructed to do it by any manufacturer. Do you guy's just look constantly for something to worry about ? (I have just put my tin hat on), to protect me from the showers of abuse & BS about to come my way. He he. I love a good debate.
