Default Hitec 7955 with Racers Edge servo horn

Anyone running this combo? Went to throw it together and the servo horn binds on the servo case when tightened down, almost as if the horn is too tall. 2 options came to mind - 1) shave the case down near the splines in order for the horn to seat fully without rubbing, or 2) just use the 2 small clamping screws to hold the horn on and forget the center main screw

Dumb question. Are u using the right servo horn? Right tooth and off-road/ on-road arm?

Fair question, ha. Using this servo horn, spline count is good, just too "tall" if you will.

why not just find a few small shims and put inside the horn to raise it off the case.

I used that combo in my rock crawler for about two years, never had an issue. Perhaps it was just a machining variance, you can file down the servo horn, it's cheaper than replacing the cases.

There's another option. I'll see what I have around the bench tonight. I have to imagine its just a variance in machining process
