I recently purchased four of these servos (HS-5065MG) and there garbage. Two of the four are so weak they stall out just by touching the surfaces. They will seem to work on the ground , but get them in the air and watch out they will just stop as if stalled out. I found this out when my Sebart 30E katana would not respond. and felt very mushy. when I landed (first flight) I noticed the servos would barely move . and had no strength at all.

Any one else having problems with this servo????
