Dual connection and reliable operation This tester supports dual connection of steering gear or ESCs, enabling simultaneous control and regulation of multiple devices. It provides stable, dependable performance to help you achieve consistent test results. Accurate and flexible adjustment It offers manual, automatic, and neutral adjustment methods, giving you flexibility to set virtual position, jitter, and neutral position with precision. This enables accurate steering gear calibration and fine tuning. Singlechip microcomputer control Powered by singlechip microcomputer control, the tester delivers stable performance and precise detection and adjustment of the steering gear. The turnable knob allows easy and accurate steering gear testing. Practical and versatile In addition to steering gear testing, this tester can control electronic speed controllers (ESCs), both brushed and brushless. It eliminates the need for a remote control device and provides convenient manual speed adjustment, effectively simulating transmitter steering through the knob. Use scenarios Bench testing and calibration of RC components Connect a steering gear and/or ESCs to verify control signals, adjust virtual position and neutral settings, and ensure stable performance before integration into a model. Prototyping and tuning RC vehicles Use the knob to manually adjust speed and steering during development, enabling rapid prototyping without a remote control, and to test response curves and stability for both brushed and brushless ESCs. Educational demonstrations and demonstrations of control signals Show how direct knobcontrolled steering and speed can replicate transmitter output, making it easier to explain and understand RC control concepts in a classroom or hobbyist setting.
