I use this servo with my HiTEC 4 channel surface radio for sailing. I have used them with Futaba, Spektrum and JR radios. I have no problems with the HiTEC servos when used with these other radio systems. I sail in fresh to brackish water here in Florida and haven't had any serious failures with any of my components. I match the proper servo to the job and keep up with proper maintenance. I am always on the lookout when these pop up as I have several boats and sail regularly. This servo is very strong and has good response,I use arm type servos in my race boats but the 785 HB in my scale yachts. Another choice is the 1/4 scale HiTEC servo that can be adapted as an arm type,but you are limited to the degree of rotation as in a standard servo. If space limits and balance are essential than go with the drum servo.Read full review

This is a sail winch for model sailboats that allow rotary winches they run well, although I do use silicone on all the seals except the turning head to prevent water seepage into the electronics in case water gets in the boat.

I have only tested this servo for functionality and not durability. It seems to work fine so no real complaints. I would like it to have better resolution but that may be a feature of a servo with large angular rotation. That is my only reason for giving 4 out of 5 stars.

It did what I expected it to do.
