Mini Spyder MT Replacement Servo Lever - Serpent 440104  [SER440104]

Replacement servo horn for Mini Spyder MT

This Serpent 440104 servo lever is an RC replacement part made for the Mini Spyder MT series listed in the product title. As the output arm that links the servo spline to the steering rods, it transmits servo rotation into wheel steering while affecting leverage and travel.

During fitting, confirm full engagement on the servo spline and check clearance around the horn and linkage. Correct seating on the spline and a securely tightened retaining screw are important to retain centring and prevent binding. After installation, run the servo through its full arc to confirm smooth, unimpeded movement before use.

From a tuning perspective, swapping servo levers changes steering ratio and mechanical advantage: a longer arm increases wheel throw for the same servo rotation while a shorter arm reduces wheel travel and raises torque at the linkage. Keep this part as a service spare or to try different arm lengths when refining steering feel without changing electronics.
