Overview
This Tekno RC aluminum servo horn uses the common 25 tooth spline and a double hole arm, so you can choose between two steering ratios simply by moving the link to the other hole. Machined from aluminum, it will not flex or strip the way a molded plastic horn does once a powerful servo starts loading it up.
The M3 clamp design is the important detail: instead of relying on a single screw pulling the horn down onto the spline, the clamp squeezes the horn around the output shaft. That removes the slop and spline wear that cause vague on-center steering feel, and it keeps the horn from working loose during a run.
Key Features
- CNC machined aluminum servo horn
- 25 tooth (25T) spline bore
- M3 clamp-style fastening for a slop-free grip on the servo shaft
- Double hole arm for two steering ratio options
- Suits high-torque 1/8 and 1/10 scale steering servos
Performance Benefits
- Eliminates the flex and slop of a plastic servo horn
- Clamp mounting prevents spline wear and loosening under load
- Sharper, more accurate on-center steering feel
- Two link positions let you dial steering rate to the track
Usage Notes
- Confirm your servo uses a 25T spline output shaft before ordering
- Center the servo electronically before clamping the horn in place
- Tighten the M3 clamp screw evenly and check it after the first run
- An aluminum horn removes the plastic horn's built-in sacrificial failure point
