I have bought these for all my servos from 1/8 buggy to 1/10 stadium truck and they seem to be working very well without issue. I like that they clamp around the spline and also have a screw from the top. the long arm and muliple holes gives you more setup options. just be sure to set your EPA! :-) the offset of the horn is toward the servo rather than outward (look closeley at the pic) but so far this has been a non issue. i will keep buying them, i haven't broke any, they are strong, don't flex and the price is right.
