RE: do hitec servo arms fit futaba servos?
ORIGINAL: ryans1000 do hitec servo arms fit futaba servos? this is on middle sized futaba servo. thanks, ryan
Futaba horns may appear to fit but will slip under mild loads, as Hitec horns are as follows:
Feather HS35, 45, HS-50 & HS-55 = 16 Spline Servo Horn.
Micro - HS-56HB only = 23 Spline
Micro Horn & Hardware Set for HS60, HS81 & HS85 = 24 spline
Micro - HS-65HB & HS-65MG = 25 spline
[Futaba 25 spline shafts (& horns) have a larger diameter]
Standard Hitec Servo = 24 spline

A.T. tells you right. They may fit, but even if the splines are the same, the diameters are different and they will slip under load.

Hitec, Appolo and Hobbico standard servos can use the same arms.
Futaba, DAD, GWS, FMA are also interchangeable; but
you can NOT interchange either group.
JR and Airtronics arms are interchangeable.

Hobbico/Tower servos are OEM by Hitec and Futaba. Accordingly, users must make sure they use the correct horns for each model of any servo. Likewise, Futaba, DAD, GWS, FMA are not always interchangeable, DAD & FMA are OEM. GWS make their own (and OEM servos) but have also produced differing "standard horns" for their own servos. FWIW, JR, Sanwa (aka Airtronics in USA), Acoms & KO Propo are all made by the same manufacturer. Further information under Servo Control horn compatability
