<!--T:11-->
You can use nearly any transmitter that provides at least 6 channels. By default 5 channels are used for controlling MICROBEAST PLUS and one channel controls the motor. If using additional features like AttitudeControl or RPM Governor a receiver with single wire output and more channels may be useful to have, but this is not a must.<br />
+
MICROBEAST PLUS can work with a lot of different receiver types and radio brands, especially with different types of radio signal protocols. Depending on which signal protocol and receiver you intend to use, the wiring layout may vary. In the following you can see all supported protocols and specific wiring schemes for each receiver type.<br />

* Never enable your radio‘s eCCPM mixing function! Disable any mixing functions for the swashplate or rudder. Each function should be assigned to just one receiver channel. All the swashplate mixing will be done by MICROBEAST PLUS. Set your radio‘s swash mixer to mCCPM (mechanical mixing) which is often called “H1”,  “1 servo” or “normal“ mixing or disable “swash mixing” if applicable.

|}<br />
 
</p>
 
* Be sure that all trims and sub trims are disabled and that all servo travels are set to 100% in any flight mode. There mustn't be any active mixing functions (for example rudder revo-mixing). Have a look at the radio’s servo monitor: each stick has to control one channel/servo output (except for thrust stick which typically controls collective pitch and motor). Note when using MICROBEAST PLUS you do not directly control the servos of the helicopter. By moving a stick you give a control command to the system which then performs the necessary servo movements to move the helictoper in the commanded direction. Each control command is bound to one servo output channel of the transmitter.

</p>
 
* Also do not adjust the collective pitch curve at the moment. For the setup procedures it has to be set as a straight line reaching from -100% to +100% (or 0 to 100% depending on radio brand).

</p>
 
* Other functions such as throttle curves, ESC switches or auxiliary functions can be adjusted as usual. But especially for the throttle make sure you can disable the throttle channel and separate it from the collective stick movement for performing the setup. You can do this by using the HOLD switch on the radio or by setting the throttle curve to a flat 0% line. Also it is advisable to create different flight modes for different flight states/rotor headspeeds.

A conventional receiver with multiple servo output connectors is what we consider a "Standard receiver". Here you connect each servo output to one specific control function at the MICROBEAST PLUS using one connection wire for each function. You have these 5 input functions (wires): Aileron, Elevator, Rudder, Collective pitch and gyro gain. Simply connect each wire to the corresponding channel output port at the receiver which you like to use for the specific function. If you don't know which stick controls which channel have a look at your radio's servo monitor, refer to your radios instruction manual or simply connect a servo to each channel testwise!<br />

A special type of single-line receiver is the remote satellite. These receivers are usually used as additional receiving unit in combination with a (bigger) main receiver to provide a more robust and fail safe radio system. But also you can directly connect one of such receivers to MICROBEAST PLUS to achieve a small and light weight radio system to be used in small sized rc models. MICROBEAST PLUS supports the following systems: Spektrum® DSM2, Spektrum® DSMX, JR® DMSS. The remote receiver can be directly connected to the small sized white pin board at the side which will provide a stabilized voltage of 3.3 Volts which is necessary to power these receivers. Alternatively if you have the optional available Spektrum® satellite adapter (Order Nr. BXA76009) also you can connect the receiver at the front to the [DI1] port, just like any other single-wire receiver, so you can keep the pin board free for connecting a sensor.<br />

Receivers with bidirectional telemetry uplink (Spektrum® SRXL2 & Jeti® EXBUS) must be connected to the pin board at the side of MICROBEAST PLUS. To connect a receiver with standard servo connectors, i.e. the SPEKTRUM® '''AR6610T''', '''AR8020T''' or JETI EXBUS receivers, you need an adapter from servo plug to JST-ZH type. We offer a special adapter if needed - Order nr. BXA76403. Voltage is the first pin from the left, Signal is connected at the third pin from the left. Minus is the second pin from the front/right.<br />
Before using your receiver with MICROBEAST PLUS make sure that the receiver is bound to the transmitter and that it is sending output data on the servo outputs and/or single-line port. Please refer to the manual of your radio system to find out how binding procedure is performed with your specific system. Also check if there is the need to perform special settings to enable the single-line data output of the receiver in case you intend to use this output port in combination with MICROBEAST PLUS.</p>

MICROBEAST PLUS can work with a lot of different receiver types and radio brands, especially with different types of radio signal protocols. Depending on which signal protocol and receiver you intend to use, the wiring layout may vary. In the following you can see all supported protocols and specific wiring schemes for each receiver type.

Warning.png Ensure a tight fit of the connectors. The pin board of MICROBEAST PLUS is designed so that the plugs firmly clamp each other when they are fully inserted. Anyhow, especially when using a receiver with single wire output it is possible that connectors are plugged in with no adjacent neighbors. Such plugs should additionally be secured against loosening.


Standard receiver

A receiver with multiple servo output connectors is what we consider a "Standard receiver". Here you connect each servo output to one control function of MICROBEAST PLUS by using one wire for each function. The 5 control functions (wires) are: Aileron, Elevator, Rudder, Collective pitch and Gyro gain. If you don't know which stick controls which channel have a look at your radio's servo monitor, refer to your radios instruction manual or simply connect a servo to test what each output is used for!

Standard RX.png


Here we show connection layouts for two common radio brands. Note that this is only exemplary, you can use any radio system on the market, not only these two brands! Anyhow, make sure that you connect the wires to the correct functions as mentioned above.

Spektrum RX.png Futaba RX.png


  • The wires for rudder, pitch and gyro are all signal wires. Although some have different color, they must be placed on the same receiver side as the the orange wires from aileron and elevator!
  • You must connect all 5 functions/wires to the receiver. When you don't connect all wires, the system will not finish initialization sequence!
  • The throttle servo/speed controller is connected to the receiver's throttle output. So using the headspeed governor function of MICROBEAST PLUS is not possible in combination with a Standard receiver!




Receivers with single wire output

A single-line receiver transmits all control functions over one single connection wire to MICROBEAST PLUS. This is done by packing all channel outputs into a digital data paket or by chaining the signals onto one line.
MICROBEAST PLUS supports the following systems with telemetry uplink:

  • Spektrum® SRXL2
  • JETI® EXBUS
  • GRAUPNER® HOTT


MICROBEAST PLUS supports the following systems without telemetry:

  • Spektrum® DSMX/DSM2 remote receivers and receivers with SRXL output
  • Futaba® SBUS (1 & 2)
  • Multiplex® SRXL
  • JR® X-Bus (Mode B)
  • Jeti® UDI
  • ALIGN® and FlySky® iBus
  • any SPPM (serial ppm) receiver .


Single wire without telemetry

  • The single-line connection wire is plugged into the [DI1] input of MICROBEAST PLUS
  • The throttle servo or ESC is connected to the [CH5] output. When using a speed controller with BEC, from here the power will be distributed to receiver and servos.
  • You can connect a power supply (second BEC wire, battery) to the [SYS] port and/or to the receiver (in case this has additional servo or battery ports). All servo ports will form a parallel power circuit (except the port [RUD|PIT|AUX]; please do not connect anything here!).


Singleline RX 3.png

with additional servo output channels


Warning.png When using a big heli with standard size servos it may be insufficient to only provide power at the [SYS] port or receiver. Adding additional power wires is highly recommended! If there are no other ports left to additionally feed in power, we recommend using the MICROBEAST PLUS HD which comes witch an additional high power input. This reduces wiring resistance and serves todays demands for a robust servo power supply.


Remote receivers (Spektrum® DSMX/DSM2, JR® DMSS, ALIGN® iBus) can be directly connected to the white pin board at the side of MICROBEAST ULTRA. Here the receiver will be powered with a stabilized voltage of 3.3 Volts! Voltage is the first pin from the front/right, Minus is the second pin from the right, Signal is connected at the third pin from the right.

Please note: MICROBEAST PLUS doesn't support connecting more than one remote satellite at a time!

Warning.png Using a remote satellite is only recommended for small rc models (helicopters of 450 size or smaller). Due to the design, one single receiving unit is more prone to radio interference and can result in reduced transmission range!




Single wire with telemetry

Receivers with bidirectional telemetry uplink (Spektrum® SRXL2 & Jeti® EXBUS) must be connected to the pin board at the side of MICROBEAST PLUS. To connect a receiver with standard servo connectors, i.e. the SPEKTRUM® AR6610T, AR8020T or JETI EXBUS receivers, you need an adapter from servo plug to JST-ZH type. We offer a special adapter if needed - Order nr. BXA76403. Voltage is the first pin from the left, Signal is connected at the third pin from the left. Minus is the second pin from the front/right.

  • When telemetry is not in use, the throttle servo or ESC is connected to the [AIL|CH5] port.
  • When using a telemetry receiver and an ESC with telemetry data connector, the ESC is connected to [ELE|DI1]. The data signal of the ESC is connected to [AIL|CH5]. (You will get further information about connecting the speed controller and setting up telemetry on the next page!)
  • You can connect a power supply (second BEC wire, battery) to the [SYS] port and/or to the receiver (in case this has additional servo or battery ports). All servo ports will form a parallel power circuit (except the port [RUD|PIT|AUX]; please do not connect anything here!).

If there are no other ports left to additionally feed in power, we recommend using the MICROBEAST PLUS HD which comes witch an additional high power input. This reduces wiring resistance and serves todays demands for a robust servo power supply.

SRXL2 receiver with standard servo connector and adapter



To connect a SRXL2 remote receiver like SPM4650/SPM4651T it is necessary to INTERCHANGE THE WIRES of the supplied 4-pin receiver connector. In this configuration you can directly plug in the receiver without the need for an extra adapter. But be very careful! Make sure plus and minus are placed properly! The signal wire is connected at the fourth pin from the front/right, minus ist second pin from the front/right, voltage (+3.3V) is the first pin from the front/right. On satellite side the signal output is on the outer side, the pin next to it is not used, then we have voltage and on the inner side comes minus.

Warning.png Never connect the 4-pin receiver connector to MICROBEAST ULTRA without modification and in wrong polarity! This will damage your receiver immediately! Check polarity at least twice before connecting the receiver to MICROBEAST PLUS. It is up to you to make sure polarity is correct. We do not assume any liability in case you do it wrong.
