MA-RX42 4CH AFHDS 2A PWM Micro Compatible Receiver Built-in 5A Brushed ESC for Flysky Radio Transmitter RC Airplane The MA-RX42 series receiver is a newly designed micro compatible receiver for micro model aircraft. It provides 4 independent output interfaces and a built-in 5A brushed ESC output interface. It also supports PWM signal output. Currently available is the V2 version. Note: This is a FlySky AFHDS 2A compatible receiver, which is no wires included. Specification: Size: 18.5*12.0*6.5mm (not including antenna) Weight: 0.9g Working voltage: 3.0~5.0V Features: With built-in 5A/1S brushed ESC Support connecting external brushed ESC or brushless ESC Supports brushless ESCs above 2S (requires BEC output 5V) Modified and perfected binding program (DSMX/2) Port diagram: Auto binding In order to solve the problem of being unable to press the frequency binding switch after the receiver is installed inside the aircraft, we developed the automatic frequency binding function. When the receiver does not receive a signal within 15 seconds after powering on, the receiver will automatically enter the binding mode (the LED on the receiver changes from slow flashing to fast flashing), and then complete the binding according to the binding operation of the remote control. Built-in brushed ESC locking function: The built-in brushed ESC lock function is to prevent the brush motor from starting accidentally. After adding this function, the brush motor will not start due to the change of the position of the throttle lever on the remote control after the receiver is powered on. After the receiver is powered on and receives a signal, when the throttle lever on the remote control is held at the lowest position for about 2 seconds for the first time (at this time, the LED on the receiver dims for about 2 seconds and then brightens again), the built-in brush ESC lock will be released. You can then push the throttle lever to start the brushed motor. Binding method: Power on the receiver first. After the receiver LED flashes quickly, turn on the transmitter for binding. If the red LED of the receiver is always on, it means the binding is successful. The AFHDS 2A protocol can be used to return the working voltage of the receiver. The AFHDS protocol is slightly different: after the receiver LED flashes quickly after powering on, the transmitter is turned on and the receiver LED changes from fast flashing to slow flashing. At this time, the transmitter is turned off and on again, and the receiver remains unchanged. At this time, the receiver LED It is always on and can be used normally The standard aircraft model (PWM) mode is 4CH with 5A brushed ESC; the multi-axis flight control (PPM) mode is 8CH, operating voltage: 3-5V, the interface uses 1.0mm JST, and the h0rizon interface is same.
