The discontinued INO-Lab HG-D250MG is the rugged, high-durability version of the HG-D250 digital mini servo, fortified with a full metal gear (MG) train. This servo is engineered to provide both the precision of a digital controller and the toughness to survive in high-stress, high-impact environments. It is a premier choice for the cyclic controls on an aggressively flown 3D 500-class helicopter, where it must be fast, precise, and durable. It is also an outstanding, bulletproof steering servo for a 1/12 scale race car or a powerful micro-crawler.
The core identity of the HG-D250MG is its indestructible digital performance in a compact package. It delivers the massive, precise torque of the advanced digital platform through a gear train that is virtually immune to stripping. It is a servo for the user who pushes their equipment to the absolute edge and cannot afford a mechanical failure. It provides the ultimate in both performance and reliability for the most extreme conditions in the mini servo class.
For the most demanding robotics applications, such as competitive combat robotics in the 3lb to 6lb classes, the INO-Lab HG-D250MG is a premier choice. Its massive torque can power a devastating weapon, while its metal gears ensure it can survive the brutal impacts of the arena. It is also an excellent choice for any high-stress industrial application where a compact, powerful, and durable actuator is needed.
