Sanwa RX-331S FM40MHz Synthesizer Receiver - Off-Road Friendly  [RX-331S/40F]

Sanwa RX-331S built for precise off-road handling

When the surface is loose or uneven, precise input timing matters. The Sanwa RX-331S Synthesizer Receiver brings steady 40MHz reception that helps keep throttle and steering responses consistent across rough terrain.

Why the synthesizer link helps on loose tracks

Synthesizer technology reduces channel drift and interference, delivering a more reliable link between transmitter and model. That stability translates to smoother control during traction changes and jumps.

Simple setup for mixed rigs

Pairing the RX-331S is direct and clear, even if you switch between models or setups. Its familiar wiring and channel compatibility make it a good pick for hobbyists who run both buggies and trucks.

Engineered to withstand outdoor use

The receiver is housed to resist the shocks and vibrations of off-road running. Sanwa's quality focus means fewer service interventions and more time on the track or trail.

For club racers and weekend bashers who need a dependable 40MHz receiver, the Sanwa RX-331S balances straightforward setup with stable performance to keep models responsive in real-world conditions.
