The upgraded redundancy hub:

Previous redundancy bus models offered a dual-power with a dual-receiver design, the RB40 allows the user to use a triple redundancy by adding a multiplex port (RX3 IN / SBUS Out) and uses a set of standard XT60 plugs which provides a safe and efficient way to provide power.

Up to 24 PWM channels with overload protection:

The RB40 supports connecting up to 24 high-voltage servos with overload protection added to each output channel. Eight of the channels (CH1-8) are equipped with current sensors.

The diversified sensors:

The RB40 is an extensive sensor module with a built-in gyroscope that supports model stabilizing functions and includes other diversified telemetry feedback like the voltage, power consumption, altitude, and a lot more. It can be used as an alternative to using a GR or S series receiver.

NFC Switch & Automatic data logging functions:

The non-contact NFC switch is an external device that enables the power to be switched on/off on command without the need to plug/unplug the battery connections. Once power is connected, the black-box function is automatically activated and immediately starts recording the data.

Menu scroll button, LCD screen & CNC case:

The RB40 features a display screen that is comparable in size to one found on the X-Lite series radio. Navigating and configuring telemetry data is even more convenient thanks to the scroll button. Even considering all these features while maintaining durability, the RB40 weighs only 260 grams thanks to the mixing design of carbon fiber and aluminum materials.
