At Menu Point N of the RECEIVER MENU we have to teach the failsafe position for throttle channel. In case the receiver signal is interrupted during operation the throttle servo/speed controller connected to the [IO2] or [IO1] output is automatically moved to this position. This particularly is the case:

• if using a single-line receiver that turns off the signal in case of signal loss between receiver and transmitter (e.g. Spektrum® satellite receiver or Graupner® HOTT receiver in „SUMDOF“ mode)
• if the connection between MICROBEAST ULTRA and receiver gets disconnected physically
• during initialization phase when the transmitter is not switched on 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 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 switch the Governor into Autorotation 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.
