Seems to be a good servo. Got 1 that was bad from the start, didn't move correctly and finally stopped working before I even got to fly. bought two extras for replacements just incase.
nice servo for tail 500 size
Leider nicht besonders solide. Fr ein 1,60 m 3D Modell definitiv nicht geeignet, obwohl die Servogre es htte vermutenlassen.
great servo centers fine en lighting fast crispy controles.

works fine on a 450 size heli! but keep youre gyro on standard frame rate! so for those who usen a 401 type gyro etc

higher frame rates will cause damage!
Ich habe den Servo in den T-Rex Kolne asl Heckservo eingebaut. Von oben in den Halter hat aber nicht geklappt, weil dieser etwas hoch in der 24g klasse ist. Von unten hat aber wunderbar geklappt.
Purchased and installed on a hk500cmt tail. I only used it for approx 5 minutes before the servo stripped out. I was running 5.5v to the servo and this servo said it can handle 6v. I wouldn't recommend this servo.
Fast and reliable servo, great combination on blade 400 with 401B AVCS. Must mount on additional tail boom holder for servo.
I bought this servo for HK450 PRO v2 as a tail servo. It`s not a straight fir. I need to adjust the corners on the mounting plate of the heli to fit.

Benutze dieses Servo seit 6Monaten an der Taumelscheibe u. am Heck im HK500. Laufen super, stellen genau zurck, gab nie irgendwelche Probleme. Ich fliege allerdings kein 3D. Kann ich nur empfehlen.
