  Thank you for choosing CROSSOCER-RX brand receiver, please read this document carefully before use. ​

  FR7012-X V2.0 is a 7CH receiver designed specifically for F3P model airplanes, it integrates 20A/3S voltage regulation and DCDC pressure type BEC power supply, but the weight and volume are quite small, so it can greatly reduce F3P flight weight, thereby making F3P flight action more flexible. Currently, this series is available in 5 versions.


1)Small size: 34.0*16.2*9.8mm (excluding antenna and power cord); ​
2)Super light: 5.2g (excluding power cord); ​
3)Working voltage: 7.4~11.2V (2~3S lithium battery power supply); ​
4)Working distance: 500~700m; ​
5)Single antenna, 75mm antenna length; ​
6)The JST power connector has been welded on the receiver; ​
7)Built-in 3A/5V DCDC step-down BEC power supply;
​8)Integrated all the way 20A/2~3S brushless ESC; ​
9)6 independent servo ports; ​
10)Support online firmware upgrade;
​11) Support GUI setting function. ​
12)Support TELEM function(Only supported by D, F2, A2 versions)

  Connection Diagram(Choose SBUS or FPORT)

  Built-in brushless ESC:

  Traditional brushless ESCs and receivers are designed as separate types, and they are connected by wires, which will inevitably increase the overall weight of the F3P device and increase the troublesome installation of electronic devices. In response to this situation, we have developed an F3P receiver with integrated brushless ESC. In order to adapt to most F3P aircraft, the built-in brushless ESC is designed with 20A/2~3S. Using this series of receivers can greatly reduce the F3P flight weight.

  ESC travel calibration:

  The stroke calibration of this ESC is the same as that of traditional brushless ESCs. Before ESC travel calibration, first turn on the remote control and push the throttle lever to the highest position, then power on the receiver (the brushless motor will give a power-on prompt at this time) -> the motor will sound when the brushless ESC detects the highest throttle Prompt -> Pull the throttle lever to the lowest position after the motor sounds prompts -> The motor sounds prompt when the brushless ESC detects the lowest throttle -> After the motor sounds prompts, the ESC saves the calibration results, and then the user can disconnect the power or start the motor.

  Frequency pairing operation:

  After powering on the receiver, press the pairing switch. After about 2S, the red LED on the receiver will change from slow flashing to fast flashing. Release the pairing switch. At this time, the receiver will enter the frequency pairing mode. operation to complete the pairing.

Note: During the frequency pairing of the D version, the distance between the remote controller and the receiver is about 30CM, and the antenna of the remote controller and the antenna of the receiver should be parallel, so that the probability of successful frequency pairing will be greatly improved.

  TELEM function(Only supported by D, F2, A2 versions)

  TELEM function is useful on monitoring battery voltage, receiver working voltage and its signal strength as well as its working temperature in real time, through which customer can get working state of receiver and battery discharging state under control, so flying out of control range and over discharging will rarely happen ( for brushless motor rotation speed or flight height monitoring, customer needs to choose a more advanced receiver)

NOTE: The effective control range of TELEM function depends on transmitter, it is possible that this would happen: the working range of the receiver is far more than TELEM function effective range, it is normal and alright!

  M.BUS1 Equipment port

  The M.BUS1 interface is a multi-function interface: ​

1) Firmware upgrade/function setting interface; ​
2) Output SBUS signal; ​
3) External other sensors (under development);

Note: It is forbidden to connect the battery to the receiver when the PC is connected to the M.BUS1 interface.

  M.BUS2 Equipment port

  The M.BUS2 interface is a multi-function interface: ​

1) output SBUS signal; ​
2) connect other sensors (under development);

  How to connect RX to GUI software(download link

  The user needs a USB programmer (USB MX-PG02, when using the FR7018T-X, the switch on the programmer is set to the I position) before using the GUI software to configure the receiver function or upgrade the firmware, and set the USB programmer’s ribbon cable Connect one end to the M-BUS interface of the receiver, and the other end to the PC. After opening the GUI software, select the correct port, click "Connect", and then each configurable function module on the receiver will load and display the current setting information of the receiver.


  Because this series of receivers have built-in DCDC step-down BEC power supply, it is forbidden for users to supply power to the receiver from the servo interface, otherwise the receiver will be burned out.

If you need a receiver with a longer working distance (1000~1500m) or a longer TELEM distance, look for the FR7018T-D.

  FR7012-X series receivers have the following 5 versions

MXL-RX62E Series Receivers/linear servos/Built-in brushless ESC/TELEM/SR3X(option)/GYRO(option)/5CH/mini RC model aircrafts


    MXL-RX62E-X V3.1 series receivers are developed on the basis of MXL-RX62H-X V3.0, on which are integrated with 5A/1S brushless ESC, the length of the board is only 8.2mm longer than that of MXL-RX62H board, in this case, MXL-RX62E-X receiver also can be installed on micro model airplanes very easily and bring customer brushless flight fun. Besides, some versions of MXL-RX62E-X supports TELEM function. We can supply 4 versions in total at present.

CROSSOVER-RX Ma-RX62HE Series Built-in brushless ESC/7CH MicroRX/TELEM(option)


    Ma-RX62HE-X series receivers were developed upon Ma-RX42E-X series receivers,  with a built-in 7A/2S(5A/3S) brushless ESC and 6 independent servo ports on board, in this case, RX62HE-X receiver can provide more power and more channels to work on larger size or more complicated model planes. We can supply 8 versions in total with TELEM function.
