Comments: This is a Single Bearing Servo. Not a Dual Bearing Servo. The Bearing is on the TOP of the output shaft. Just thought people would like to know. I use them for Throttle only and they do a great job.

March 19, 2013Application(s): Ailerons, rudder and throttle on .40 and .60 sized airplanes
Comments: Great servo for up to a .60 sized airplane. They are reliable, quiet and cheap (price wise)! They come neatly packaged and come with rubber grommets and eyelets. I have used these for over a year without a problem, until the Hitec servo I had on the elevator gave out. Crashed into the runway and destroyed stripped the gears off the Futabas. For Ailerons, Rudder and Throttle I use the S3004 since they are very reliable. I use Futaba S3010 for elevator since they are stronger, but every bit as reliable as the S3004.
