SKU CH-884A-QBN9H

Set of five CNC aluminium 25-tooth servo horns with M3 mounting holes on 14 mm spacing for standard servos

  • Product typeServo Arms
  • CNC aluminium construction resists stripping under high torque
  • 25-tooth spline fits MG995 and MG996 servos directly
  • M3 thread holes on 14 mm spacing match standard servo patterns
  • 3 mm centre bore aligns precisely on 20 mm body diameter
  • Five horns and twenty screws equip multiple control surfaces

Servo Horn 25T for Standard Servos

This pack supplies five CNC-machined aluminium servo horns with a 25-tooth spline. They fit Hitec, Parallax, Futaba and other standard servos measuring approximately 40 by 20 by 36 millimetres. Each horn includes four M3 threaded holes on a 14 millimetre spacing. The silver finish resists corrosion in outdoor models.

Ideal for RC Vehicles Using 25-Tooth Splines

Builders repairing or upgrading RC cars, boats, aeroplanes or helicopters with compatible standard servos will find these horns a direct replacement. The included twenty screws simplify installation. Modellers whose servos use a different spline count or mounting pattern must choose a different horn.

25-Tooth Spline Matches Compatible Servos

The 25-tooth spline is the single specification that determines fit with your servo output shaft. Verify that your servo uses a 25T spline before purchase; other tooth counts will not engage. The 14 millimetre hole spacing and 3 millimetre centre bore must also match your servo arm geometry.

Questions about this item

What servo spline count does the 25T horn require?

The horn fits servos with a 25-tooth output spline such as the MG995 or MG996.

Will the 14 mm mounting-hole spacing match my existing Futaba-standard servo?

Yes, the 14 mm hole spacing matches Hitec, Parallax, Futaba and other standard servos around 40 × 20 × 36 mm.

How can I confirm the horn is seated correctly after installation?

The centre bore should sit flush on the 3 mm output shaft and the four M3 screws should align with the 14 mm hole pattern.
