Servo lever for Mini Spyder MT

This Serpent SER440104 servo lever is an RC-scale replacement designed for the Mini Spyder MT line named in the product title. As a control arm that connects the servo output spline to the steering linkage, its role is to transfer servo motion into wheel steering while influencing leverage and travel.

When fitting this part, verify fit to your servo spline and the clearance around the horn and linkage. Proper seating on the servo spline and secure fastening of the retaining screw are essential to preserve centring and to avoid binding. After installation, confirm smooth travel through the full steering arc before field use.

In tuning terms, changing the servo lever alters steering ratio and mechanical advantage: a longer arm increases throw at the wheel for the same servo rotation while a shorter arm reduces wheel travel but raises torque at the linkage. Use this part as a spare or to swap lever length options when adjusting steering responsiveness without changing electronics or servo output.
