Notes

The discontinued Hextronik D-MG16 is a compact servo that has become a cornerstone component for the modern builder, celebrated for its role in making high-performance features accessible to all. It brilliantly fuses the intelligence of a digital (D) controller with the resilience of a metal gear (MG) train, all within a versatile 16-gram package. This servo is an enabler, empowering hobbyists to upgrade their models with a level of performance and durability that was previously reserved for expensive, premium brands. It has the precision for the flight controls on a demanding park flyer and the toughness for the cyclic on a 250-class helicopter, making it a true multi-role champion for the budget-conscious enthusiast.
What makes the D-MG16 so iconic is the way it changed the landscape of the hobby. It proved that you didn't need a large budget to build a tough, responsive, and high-performing model. The digital controller delivers a crisp, no-slop feel with powerful holding torque, while the metal gears inspire the confidence to fly harder and attempt more challenging maneuvers without fear of stripping a gear in a minor mishap.
This same spirit makes the D-MG16 a legend in the DIY robotics community. It is the go-to servo for countless projects that require a combination of strength, intelligence, and affordability. It is powerful and tough enough for the leg joints of a sophisticated walking robot and precise enough for a functional gripper on a robotic arm. It is, quite simply, one of the most valuable and enabling actuators for any creator working on a budget.

Application(s): tail servos on Freewing SU35

Comments: Two operate the SU35 elevators....both have a jittery but accurate motion up and down. they centre OK and are quiet enough until moved when they jitter in unison to the input position. It is as if they were stepping rather than a smooth action. Pretty frustrating..........Any ideas??

Application(s): Mini e revo steering servo

Comments: I installed this in my traxxas mini e revo as a replacement for the stock servo. After 3 minutes of testing, the servo stopped working. This was my first experience with this servo and i'm not too satisfied that it stopped working after such a short time without any stress on the servo.

Application(s): 42" pitts electric bi plane. ailerons, rudder, elevator

Comments: first off this is the same servo as tower pro. I went through 8 servo's to come up with 4 good ones. Price means little when half of what you buy doesn't work. the ones that do work are fine, I place little trust in anything that arrived with only 50% working rate
