What is Fail-Safe Mode?

If you use the FAIL-SAFE function, and set it up properly, should the receiver signal

somehow be interrupted or interference were to occurred, the servos will move to

your pre-set FAIL-SAFE position you previously stored in the receiver during the

FAIL-SAFE set-up.

If FAIL-SAFE has not been activated, the signal is switched off after the HOLD period

of 1 sec. This means that the servos become “soft” and remain in their last

commanded position under no load (this may equate to full-throttle!), until a valid

signal is picked up again.

In the interests of safety, we recommend that FAIL-SAFE should always be

activated, and the FAIL-SAFE settings should be selected so as to bring the model

to a non-critical situation (e.g. motor idle / electric motor OFF, control surfaces

neutral, or full brake, etc.)

When LED On (Fail-Safe Mode On):

Press the function button once to switch to the hold mode, the LED will goes off and

indicates that the receiver is in Hold Mode.

Note: once you switch to the hold mode all the saved Fail-Safe position will be

deleted.

When LED Off (Hold Mode On):

To switch to the Fail-Safe Molde, first adjust all the control knobs to the fail-safe

position you prefer, then press the function button once, the LED turns on at the

same time the fail-safe position will be saved.

Once Fail-Safe/Hold Selection Mode activated , you can keep switching the mode by

pressing the function button.
