Been using 4 HD 9110MG for about a year and half and had no problems with them so far. The specs are very good, (digital,metal gear,has b.bearings, 10 kg/cm of torque, able to work with 6 v).. and as I needed to replace the servos in my Kangaroo, (in Brazil a new jet servo is sold for $200+ each) this servos maked a lot of sense. and as they worked for me I bought another bunch of them for a new mid-sized jet project.

Only thing that I didn´t liked is the wire, wich seems to be more fragile than JR or Futaba.. easy to get a dent on it if left out of the wing while assembling the plane. for example.
