i recently obtain 4 Futarba s9154 servos with disc horns

can anyone point help me or know where to get hold of horns that that will fit them

looking for a set or individual horns that will fit an 8 mm output shaft

Speed: 0.14 sec/60° @ 4.8V
Torque: 64 oz-in (4.6 kg/cm) @ 4.8V
Dimensions: 1.9 x 1.1 x 1.0" (48 x 27 x 25mm)
Weight: 1.9oz (53g)
Output Shaft Diameter: 8mm
Power Supply: 4.8V (Futaba does NOT recommend using 6V)

tried both don't stock SA

the servo shaft is not standard, it is 8mm

Those are a unique spline size. What are you going to use them in?

my intentions was to used them as a rudder servos or aileron servo in my 7ft monocoupe, or has replacement servos for the beaver wings

not really decided

alternatively i could use them on the greenley wings up

i need the arms

For some reason i can't find any in the UK? But you can get them in the US:

They are total overkill for aileron servos on something like that. 3001s would do! If you are fussy, then Hitec 645s would be ample. Those are digitals, suitable for big 3d models. Warning:
S9154 Digital Servo Precautions,
-It is best to avoid long leads and Y-harnesses especially with
standard grade wires. If problems are encountered, consider using
heavy duty wire such as Futaba's Heavy Duty Series or Hobbico's
Pro Series, minimizing lead lengths, and/or removing Y-harnesses.
-Current Drain: This digital servo is specially designed for high-
torque or high-speed, therefore very high current drain is normal
at startup.
