Gary- You were right the servo horn splines were stripped. I couldnt get them to move by hand but when I held the horn and had my son try to steer the car I felt it slip. I looked at it at the track but I guess my old eyes arnt what they used to be! Could you post the number of splines for Hitec and any other brands you know of? I always forget to write that info down when I find it.
Thanks
