Precision Inputs and Braking Assist

The Sanwa GEMINI-S brings features that matter on track.

Fine Adjustment and Power Monitoring

For fine mechanical alignment the Servo Sub-Trim allows tiny servo position tweaks that make a big difference in steering neutrality. The Battery Voltage Monitor keeps track of pack health so you can avoid surprises during practice or race runs.
