Precision Stick Control for Serious Drivers

The Sanwa GEMINI-S Transmitter gives crisp stick control and useful tuning options for drivers who want reliable responses on both smooth tracks and rougher surfaces. Its compact layout helps you stay consistent lap after lap.

Brake Control and Responsive Curves

The GEMINI-S includes Anti-Lock Braking System (ABS) to reduce wheel lock in heavy braking zones. Combined with Exponential and End Point Adjustment, you can soften or sharpen control curves to suit grip levels and driving style.

Quick Adjusts for Different Terrains

Servo Reversing and Steering Dual Rate allow quick changes between vehicle setups so you can tune steering throw and direction ahead of a run. These functions are handy when moving from flat asphalt to rougher layouts.

Small Tweaks that Matter

Servo Sub-Trim gives you micro control over servo centring to reduce unwanted steering drift. The Battery Voltage Monitor keeps a record of power levels so you can plan pit stops or battery swaps without guesswork.

Multiple Model Support and Receiver Compatibility

Save up to ten models to swap between different vehicles. The GEMINI-S works with RX-391 and RX-391W receivers, making it easy to pair with multiple cars or upgrade receivers as needed.

With fine adjustment options and reliable receiver support, the Sanwa GEMINI-S is a versatile stick radio for focused club racers and hobbyists who want consistent performance.
