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.)
