The HS-311 is a perfect match for the SMS. We have modified many 311's and are ready for you. Each modified servo is documented over an integration protocol so you know exactly its capabilities. Every shiped HS-311 supermodified has an INDIVIDUAL integration report that let you know exactly its characteristics. Also in our lab we have investigated the correct P,I,D (at no load) so you get the optimal repeatability!
