Our R&D design team has in excess of 100 years collective modelling experience and we have seen servos fail of all brands and types. There are good and bad ones made by every manufacturer and the important factor for you as the pilot/ plane builder, is to select the best servo for the right application firstly and then use a reputable brand servo’s.
Invest in proper servos on the major control surfaces like Elevators and Ailerons and use digital servos only on flight controls, never on geardoors. Flaps work better with Analog servos also.
Aviatix has partnered with CYS because in our experience their top end servos are every bit as good as the ones manufactured by the well known brands like Futaba, JR and Hitec. They give us and our customers the backup we need and stand by their product.
