Servoblock is a metal structure to be applied to servos. A normal servo motor generally has a plastic body and a series of gears that are not very resistant to mechanical stress. With the servoblock, the mechanical stresses are discharged onto a very resistant aluminum shaft. The servoblock combines the practicality of servo-type control with the resistance of an aluminum structure. It is available for both Hitec and Futaba servos (or compatible). Suitable also for servants of Chinese sub-brands.
