    Application(s): Rudder servo on Soling 1 Meter sailboat

    Comments: Strong, used LiFe battery lasted about 2 years of seldom use.

    Application(s): Spead break swift s1 4m

    Comments: Have to change them every 20 flights ,speed breaks of 30 cm

    November 5, 2016

    Application(s): Aileron on a 1400mm plane

    Comments: Smooth and precise, but only 4 stars as hitec's quoted speed figures are very optimistic. Still a good servo for a good price.

  • CCL

    March 3, 2014

    Application(s): 500 heli cyclic servo

    Comments: I use 3 of it for 500 heli cyclic servo with KBAR FBL system and it work great & reliable. the metal gear is not stripple even hard crashed.

  • GP

    April 30, 2012

    Application(s): RC aeroplanes

    Comments: This is an excellent, strong, reliable servo. If you need something smaller than a standard-size servo but larger than the usual micros, this is a good choice. It is thinner than a Hitec HS-425 and thicker than a Hitec HS-85, and has torque between those as well. The torque is pretty high, the centering is good, it doesn't strip, it is very reliable.
