Overview
Get a slop-free, race-grade steering connection on your Redcat Ascent 18 with the Hot Racing CNC Aluminum Clamping Micro 25T Servo Arm. CNC-machined from aluminum and finished with a durable black anodizing, this clamping single-arm horn delivers a permanent, vibration-resistant link between the Ascent 18's micro-spline servo and the steering linkage.
The clamping design firmly locks onto the servo's micro 25-tooth output spline, eliminating the spline wear, slop, and stripping that plague stock plastic horns over time. The result is sharper steering, more consistent feel, and a connection that'll outlast multiple servos.
Key Features
- CNC-machined aluminum construction
