MPI S100-MG Winch in General Discussion Posted October 29, 2019 I have happily used Kingmax sail winch servos for some time. When you buy from some outlets they say that the servos are programmable but you can only seem to buy them preset in terms of number of turns, almost all of them have the same rotation rate etc. For the sw22hv, it would seem to be able to be set to what you want except that you have to have the means to do it . I believe that you need this little gizmo to do it https://www.amazon.com/KINGMAX-22kg-cm-programmable-Bearings-Waterproof/dp/B07SMSWVF8. Does anyone know any different ?
