There isn’t much to say about these Dymond D-47 servos other than “smoother, fast and powerful”.

D47 Dymond Micro Power Servo are the choice of competition pilots flying gliders, airplanes, helicopters and drones.  Only 8mm thick and voltage range of  3.7 to  7.4v  total weight of 4.7 grams,  an outstanding servo for serious DLG pilots and my personal favorite servo to be used on the FireFly 2.0
