December 12, 2016Application(s): The application for the S9202's I have is in a Great Planes Super Decathlon 40 model and they both run the rudder and elevator.
Comments: I have enjoyed the dual ball bearing and coreless motors they are extremely smooth and strong. They run on a six volt battery pack so I get 69 ounces of torque. Best analog equipment around wish Futaba would bring them back into production. I purchased them back in the early 1990's. I had to repair nylon gears on the one that runs the rudder due to a crash mishap but other than that they are still going strong today in 2016.

Comments: The best servo I ever used and I have used a lot. The gears work perfectly. You can feel the quality when you move it with your fingers.
