These servos are good, precise and strong enough, but they need a (handmade) small washer to inhibit jitter. Place the washer between the linear case and the end cap. See files.I am sorry to report, that unlike other reviews, I say "THE KING IS NAKED".
This servo has faulty design (in my opinion).
If the servo jams, binds, encounters too much external resistance to
horn movement - it will butn out a FET in 2-3 secconds.
maigc smoke escapes too easily. other brands have protection against
I will not use the 5 remaining serov's I have (out of 7 I ordered and burnt
2).What a disappointment. I bought two servos and both jittered a lot and then went to full travel. This happened many times on the bench so I never used them in a plane. I tested with a servo tester, so its not the receiver thats the problem.
If HK fixes the jitter issue I will try again as they seem to be small, light and a good priceLittle and light servo. Have use it on a few indoor aircraft, unfortunately the servo jitters too much and if it get stuck it will burn very easily.I know about many bad reviews. Probably I had good luck, mine work fine with Efilte rx. First servos I bought from HK which have the JST Nano plug which fits for micro Eflite rx.
Could HK also sell these plugs? Would be fine for changing plugs on other servos.
