    Application(s): used for throttle servo in my 26cc 1/4 cracker box boat.

    Comments: the servo work good enough for the throttle. Brand new out of the shipping box i noticed it has about 1mm of play in the gears before it was ever used. I will see how it performs over the summer and post back if it gets any worst.
