February 17, 2017Application(s): RC Laser
Comments: Frank: it's the only servo the RC Laser Allow in the rules so all racing is the same, if you put a faster winch in you will be out of class and not able to race. Mine has been in the boat for 4 years regular weekend racing no problem.

February 20, 2015Application(s): I used this servo on my RC Laser sailboat
Comments: It is painfully slow, it takes a long time to get the sail in.

February 28, 2014Application(s): Pan Unit
Comments: I hate to give it a 4 instead of 5, but I only do because it's not as fast as I had hoped! I'm using this for a 360 pan on my FPV ground vehicle through a Servo City tube pan, and it's super strong with this application, and has VERY little play! My only gripe is I wish it was twice as fast. Also, it's not the quietest of servos, not LOUD but certainly not quiet.
