You have to count the splines (teeth) on the top of the servo to find out what will fit. Some servo horns will have a mark on them "F"(Futaba) 25 teeth, "J", etc. etc. 25 tooth count is a common spline number with servo horns that is needed. Hitec servos use 24 tooth a lot of times and Airtronics/Swana stuff uses 23 tooth horns in general.
