    Plasti Dip a Hitec 7955

    I am planning on applying plasti dip on my Hitec 7955 servo. Should I cover cover the whole sides of the servo or should i avoid covering the aluminum on the sides?

    Do NOT cover the aluminium.
    It is a heat sink for the servo.
    Mine has been wet many many times its sealed pretty good.
    I have not done anything to it
    I don't submerge it on purpose....much

    I should probably do something
    They are pretty well made.
    I still don't recommend submarining it.there is alway some risk involved.

    Yeah definitely do not cover the Aluminium heat fins around the middle of the servo!! You do not want it to overheat.

    I pulled mine apart, covered the insides (circuit board on the bottom) with liquid tape and then filled the top and bottom of the servo case with grease - especially around the output shaft and seals.

    Yeah I agree with all above. I recently installed and plasti dipped my Hitec 7950. I taped off the entire heat sink all the way around the servo. I also took the servo apart before I plasti dipped it and added a touch of grease inside the case to the underside of the output spline just to hopefully give it a little more protection from water trying to seap in.

    If you tape off the heat sink, when done using the plasti dip just take your time and score the edges of the tape first with a hobby grade blade...and then just peel away the tape leaving the rest of the servo covered in plasti dip and the heat sink still exposed. Has worked well for me so far.

    Just had mine apart to replace a gear. O rings seal it pretty good so I greased the output add some liquid tape around the wires calling it water resistant.
