Servo Horns and Hardware Sets
A servo horn transfers the output of a servo to the control linkage, so matching the horn to your servo spline is essential for a secure, slop-free fit. This category collects servo horns and hardware sets keyed to specific servo splines and brands.
Brand and Spline Fitments
Sets here are grouped by the servo they fit. The Hitec HS-755 horn and hardware set uses a 24 tooth spline, while the Hitec HS-65 class set fits a 25 tooth micro spline. Du-Bro micro horn sets are offered for servos such as the Spektrum DSP60 and ParkZone SV80, and the Dymond D47S set includes matching hardware.
Choosing the Right Set
Because spline counts vary between manufacturers and servo sizes, check the fitment listed for each set against your servo before ordering. Many sets bundle screws and linkage hardware alongside the horn itself.
Browse the sets below to find one matched to your servos.
