This is the unit that you would use to go between your standard Futaba/JR/etc radio receiver and your 4QD speed controller. It will proportionally operate ONE controller from a channel of your reciever or other standard Pulse Position Modulated input with an active failsafe system. The units are used extensively in high-power radio-control applications utilizing 4QD‘s 4QD, Pro and NCC motor speed controllers.

Features include proportional control of a single channel with an output resolution of 64 states over the full stick displacement. Switched output mode for use in applications requiring a Radio-Control Switch. An on-board signal validation routine and a failsafe system give stable operation and "power-down" of the output in the event of transmission loss or hardware failure.

Features
• Single Channel Radio Control Electronic Speed Control utilising RISC AVR Surface-mount Micro-controller.
• 64-State PWM (Pulse Width Modulated) Proportional Output.
• Optocoupler on inputs.
• Reverse Driver.
• Zero Output Failsafe System.
• Switched or Proportional Output Modes.
• Signal Validation and Rejection for Noise Immunisation.
• Low Power Consumption: powered from the controller.
• Compact and Lightweight Design.
