Receiver Menu - Throttle failsafe

Adjustment on the device

At Menu Point N of the RECEIVER MENU you teach the failsafe position for throttle channel. In case the receiver signal is interrupted during operation the throttle servo/speed controller connected to the [CH5] Output is automatically moved to this position. This particularly is the case:

  • if using a single-line receiver that turns of the single-line signal in case of signal loss between receiver and transmitter (e.g. Spektrum® satellite receiver or Graupner® receiver in „SUMDOF“ mode)
  • if the connection between MICROBEAST PLUS and receiver gets disconnected
  • during initialization when the transmitter was not switched on before or was switched on too late and the radio link between transmitter and receiver is not established yet

Additionally the failsafe position is used by the internal Governor function in case you're using a helicopter with electric drive system. Here the throttle is moved to the stored failsafe position when you set the Governor to Autorotation bailout mode!

Note:

  • The fail-safe function is not effective if the receiver continues sending data even if the radio link is interrupted. In this case the failsafe setting of the remote control system may take precedence.
  • To avoid accidents, you should program electric motors to “off“ and reduce throttle on nitro helicopters to idle. The other control functions will be set to „position hold“ in case of signal interruption. For these setting a failsafe position is not provided.


To teach the failsafe position simply set the throttle channel on your remote control to the desired position and press the button briefly. If you did not connect a function to CH5 Output and don't need throttle failsafe, press the button to complete setup anyway!

Warning.png During failsafe setting the CH5 Output is enabled and can be controlled by the transmitter channel that is assigned to throttle function. This allows to check your throttle position in reality. When using electric models make sure the motor is disconnected from the ESC or the pinion is removed from the motor, so that it will not drive the model by accident.




Setup with StudioX

After you've set the control functions you will be asked to program the failsafe position for the throttle channel. In case the single-line signal is interrupted during operation, the throttle servo/speed controller connected to the [CH5] Output is automatically moved to this position. This particularly is the case:

  • if using a single-line receiver that turns of the single-line signal in case of signal loss between receiver and transmitter (e.g. Spektrum® satellite receiver or Graupner® receiver in „SUMDOF“ mode)
  • if the connection between MICROBEAST PLUS and receiver gets disconnected
  • during initialization when the transmitter was not switched on before or was switched on too late and the radio link between transmitter and receiver is not established yet

Additionally the failsafe position is used by the internal Governor function in case you're using a helicopter with electric drive system. Here the throttle is moved to the stored failsafe position when you set the Governor to Autorotation bailout mode!

To teach the failsafe position choose "Proceed" when asked to teach the failsafe position and set the throttle channel on your remote control to the desired position. Then press Set to save the position. If you did not connect a function to CH5 Output and don't need throttle failsafe, press Cancel to complete setup!

After function assignment click Proceed to start teaching the throttle failsafe position

Move throttle to lowest position at which the motor is turned off
