Program tips > Using Failsafe on M-LINK receivers

Here's a quick summary of how failsafe works on Multiplex M-LINK receivers.

Out of the box

Failsafe on M-LINK receivers is initially inactive. In the event of a signal loss, the servos are held in their last commanded positions ('HOLD') mode.

Storing the failsafe positions

Setting the failsafe is really easy. Here's how:

  1. Switch on the transmitter
  2. Move the sticks to the required position,

then either:

Two methods for setting failsafe on M-LINK receivers.

Failsafe remains active until a new configuration is set, or until a factory Reset is performed.

Operation with failsafe

Once failsafe is set, the following will occur in the event of signal loss from the tx:

  1. First 0.75 secs: servos are held in last commanded position ('hold' mode).
  2. After 0.75 secs: servos are driven to the failsafe positions.
  3. After 16 secs: receiver ceases to actively maintain the servo positions (servos go 'soft').

Normal operation is resumed once the signal is restored.

Good practice

When moving an M-LINK receiver from one model to another, don't forget to re-configure the failsafe settings for the new model. Alternatively perform a "factory reset" on the Rx to place it back in the default Hold mode.

For electric models, the very first task should always be to configure the throttle failsafe to idle. Do remember to do this before arming the motor!
