Comments: it's not bad this servo. I speed tested it, and it meets it's required specs. It's all metal geared. It would of been nice if it had 2 Ball bearings like the Emax es09md. But for the cheap price, it's good and it's nice and light. As for slop, I've seen worste, it's very minimal slop.

March 13, 2014Application(s): Tricopter tail motor
Comments: so far bought 2 and 2 have died, the first burnt out before I even got it in the air, and may have been a defect as it got exceptionally hot very quickly. The other worked for 3 days, but then began to no longer center and work in one direction or the other, seemingly at random.

Comments: Very happy with performance and accuracy. Lots of value for the money!
Have 20+ units in operation and had only one fail me.Maxim K.
July 26, 2012Application(s): Parkfliers as VA-Models Katana and Hyperion Extra 10e
Comments: Good servo for the price. Smooth operation, good resolution.
But not so fast as declared.
Real speed varies from 0.12 sec / 60 grad / 4.8V for good item to 0.17 sec for bad.
Typical speed is about 0.137 sec / 60 grad / 4.8V.Neoalchemist
January 17, 2012Application(s): cyclic servo on 450 class helicopter
Comments: I never got to see if these work or not because the casings practically crumbled to powder upon installation.
