Russ
July 29, 2018Application(s): Elevator, rudder, aileron, flaps. On a Glider
Comments: 6 out of 6 jittered real bad on Servo checker. Put them on a RS7008SB receiver and 14SG futaba radio (brand new) same result. I’m glad I checked these before installing. PURE JUNK.
Parkflyer
February 13, 2010Application(s): I installed 4 of these into a 1m wingspan 3D parkflyer, one on each control surface.
Comments: One aileron servo and the elevator servo start vibrating furiously the first time you move the sticks and return them to neutral. I've tried different TX/RX combinations but the vibration remains. The movement at the trailing edge of the control surface is ±10mm which makes the model unflyable. These servos are a waste of money, Junk IMO!
