August 8, 2013Application(s): 1/10 offroad truggy steering servo
Comments: Worked great till the servo case cracked at the mount points and fell apart. Plenty of power and torque but the case is made of cheap plastic and is brittle. For the price they are good but just mount them really securely. Speed and torque are high and it centres well will no jitter. It wont compete with a top of the line branded servo but is one quarter the price of name brand servos with similar performance. Maybe I just got a bad one. Bottom line: Ok for 1/10 bashers but not for anything larger or for racing.

Comments: Powerful, good self centering, and the right price for a servo that is frequently in contact direct with salt water.
