When using a single-line receiver it is mandatory to define the function assignment for the receiver output channels. A single-line receiver bundles the control information to data packages or serialized electrical signals. So by default it is not clear, which channel controls which (stick) function.

Please compare the preset function assignment at the bottom and check if functions are setup in a similar ways on your radio system (i.e. check your stick monitor on the radio). When your assignments are different, you can teach the assignment to MICROBEAST PLUS at Menu Point B and following. Otherwise you can simply load the preset configuration by a press of a button.

Adjustment on the device

If not already done enter RECEIVER MENU and scan your receiver at Menu Point A. Then setup will skip to Menu Point B.

If the Status-LED lights in red color this means either there is no valid remote control signal available or that you did try to assign two or more channels to a function. So check if the receiver is connected and powered properly and that you're only moving one channel at a time when trying to do the manual function assignment.



Default function assignment

Refer to the tables at the bottom and identify the column that represents your receiver type. Check if your radio transmits the channels in the given order, respectively each stick function on the radio is using the specified channel number. To know the channel assignment of your transmitter you can check the user manual of the transmitter or look at the servo monitor of the transmitter. In order to load the preset channel assignment hold down the button for at least 2 seconds and release. The yellow Menu-LED will immediately jump to Menu Point M or N.

Push and hold the button at Menu Point B to load the preset function assignment



Manual function assignment

In case the function ordering of your radio system differs from the given tables below, you have to manually assign the channels/functions step by step. This is done by simply actuating the appropriate function on your transmitter at each of the Menu Points B to I (J for devices with AttitudeControl/rescue). Each menu point represents one control function.

When you move the control stick/adjust the channel with the transmitter, the flashing Status LED indicates that the channel has been detected. It is important that only one channel moves on the radio whe the requested function is activated. Otherwise MICROBEAST PLUS can't recognize the desired channel. The Status LED will not flash in this case! If you have moved the wrong stick/switch, just move the correct one afterwards. MICROBEAST PLUS remembers only the last function that was operated and confirms it with blue flashing of the Status LED!

Move the collective at Menu Point B, then push the button when Status LED flashes


After teaching each function, briefly press the button to save the assignment and to skip to the next function. Once a channel was assigned, it is no longer available and is ignored by MICROBEAST PLUS for the remaining process! Thus, after learning of the collective pitch function at Menu Point B you can enable the throttle function (remove throttle hold) and teach the throttle channel later at Point G by re-operating the thrust stick there. The collective pitch channel no longer be considered as this channel has already been assigned previously.

The first 6 functions must be assigned as they are necessary for the basic flight control and the button remains locked until you operate a new control function. The other functions are optional to assign and can be skipped. If special features like AttitudeControl or Headspeed Governor are not installed on your device, the specific menu points for assignment will not be accessible at all.

  • The assignment for Aux [CH6] Output at Menu Point H can be skipped by pressing the button without teaching a channel for this function in case it is not used.
  • Likewise, the assignment of the channel for internal (nitro) governor can be skipped in case it is not needed or if you don‘t want to control the governor with a separate channel, e. g. if your transmitter does not provide enough free channels. By skipping the assignment the internal governor function will use a different operating mode that allows to control it via the throttle channel (set at Menu Point G) if you like. When used in an electric model the internal governor is controlled by the throttle channel (set at Menu Point G) in general. In this case the assignment at Menu Point I can be skipped anyway, as an assignment will have no effect.
  • Finally at Menu Point J you have to assign the channel that is used to engage the AttitudeControl/rescue stabilization (only when you've installed the this feature on your device). Again, this can be skipped if not needed or if you don‘t want to use a separate channel (or in case you haven't enough free channels left). Please see the section about using AttitudeControl for further details.

Setup with StudioX

In StudioX open Control Setup and start the receiver Scan. When this was successful a dialog will appear asking for what to do next.

Default function assignment

Refer to the tables below or compare the function assignments shown on the screen and make sure your radio transmits the channels in the given order, respectively each stick function on the radio is using the specified channel number. To know the channel assignment of your transmitter you can check the user manual of the transmitter or look at the servo monitor of the transmitter. If the assignment on your radio matches the preset functions, simply choose Use default from the dialog.


Manual function assignment

In case the channel to function ordering differs from the given setting, you have to manually assign the channel order step by step. This is done by simply actuating the appropriate channel function on your transmitter at each of the Menu Points B to I (J for devices with AttitudeControl/rescue). Each menu point represents one control function to assign. When you're ready click Teach in the "New receiver detected!" dialog and start with function allocation at Menu Point B.

  • When you move the control stick/change the channel output on the transmitter, the Status LED will flash when the channel has been detected and the channel number will appear in the display. The setup will jump to the next function assignment automatically.
  • It is important that only one channel moves on the radio whe the requested function is activated. Otherwise MICROBEAST PLUS can't recognize the desired channel. The Status LED will not flash in this case!
  • Once a channel was assigned, it is no longer available and is ignored by MICROBEAST PLUS for the remaining process. After learning of the collective pitch function (at Menu Point B) you can enable the throttle function (remove throttle hold) to teach the throttle channel at Menu Point G with the thrust stick. The collective pitch channel will no longer be considered as this channel has been assigned already.

At first move the stick for collective. Make sure only one channel is moved on the radio otherwise MICROBEAST PLUS is not able to detect the movement!

Proceed with the other function in similar manner

The optional functions can be skipped if not needed. See text below!

When skipping the channel number will be shown as -



The first 6 functions must be assigned as theses are necessary for the basic flight control. The other functions are optional and can be skipped. If special features like AttitudeControl or Headspeed Governor are not installed on your device, the specific Menu Points will not be shown at all.

  • The assignment for Aux [CH6] Output can be skipped by pressing the "Skip" button without teaching a channel for this function in case it is not used.
  • Likewise, the assignment of the channel for internal governor can be skipped in case it is not needed or if you don‘t want to control the governor with a separate channel, e. g. if your transmitter does not provide enough free channels. By skipping the assignment the internal governor function will use a different operating mode that allows to control it by the throttle channel if you like. When used in an electric model the internal governor is controlled by the throttle channel in general. In this case the assignment can be skipped anyway, as it will have no effect.
  • Finally, you can assign the channel that is used to engage the AttitudeControl/rescue stabilization (only available you've installed the PROEDITION Upgrade on your device). Again this can be skipped if not needed or if you don‘t want to use a separate channel or in case you have no more free channels left). AttitudeControl can still be used then. In this case the channel for the tail gyro gain is used to engage AttitudeControl or can be enabled separately using the Bank Switch feature. Please see the section about using AttitudeControl for further details.

Modified assignment with PROEDITION firmware (*)
When using the PROEDITION Firmware upgrade by default the channel for function Aux [CH6] will be used to control the AttidudeControl gain. The control for Aux [CH6] will be moved to channel 9 (or AX4 for Spektrum® radios).
Please note: When you don't want to use a separate channel to control the AttitudeGain or when your radio doesn't have a sufficient amount of output channels, you have to skip the assignment for the AttitudeControl function manually!
