i have install this servo in my trex 550 E. It works very good an hold the tail on his place. I will by this servo again.Tolles Servo Benutze es als Heckservo fr einen 600er Heli und funktioniert Topseems great well packed the control armes look a little tacky but for the price you cant complainFunktion: Kraft, gute Stellgenauigkeit, exakte Neutralstellung, stark.
Ist bei meinem 700-ter als Heckservo eingebaut.
Nur ein Minuspunkt: Servo gibt im Ruhemodus sehr lange Gerusche von sich ab.
I have bought new servo after firs one died in second flight and i am very happy with it, it is very fast, acurate and my tail is rock solid. It was just bad luck with first buy i guess.
ByeHello, I have no problems at all with this servo. It`s fast and centers very well. I tested it for half an hour before installing in my TSA 700E heli on tail. The only thing is that there is a little bit play in the geartrain, but in flight you don`t notice this.Hi, my new servo just blocked in second flight on my hk550gt tail (i am using 6v and Assan GA250 gyro on 1520ms/250Hz). I have landed safely with autorotation and throttle cut. Fortunately the servo stopped right in center and i was able to save my heli. I have opened the servo and found out that motor burned and blocked (i could not even turn servo horn), the gear is all fine. Maybe i was just unlucky with mine servo but i think it should not burn like that (and for 550 size heli 5.5Kg should work fine on tail, or not?) After first flight (6min of soft 3D) the servo was barely hot so i asume overheating vas not an issue.
Otherwise the servo performed realy fine, very fast, perfect centering and no slope.
When i opened the servo, i have to tell that it looks mechanicaly very well made inside and greased well.tested today on my spectra-g heli 23cc petrol zenoah and workt just fine powerful silent fast and direct wil write a new review after longer testing
