FAIL-SAFE and Hold Mode Setup
FAIL-SAFE point you previously stored in the FAIL-SAFE set-up. Make sure you set the FAIL-SAFE function
properly.
If FAIL-SAFE has not been activated, the signal will switch off after the HOLD period of one second. 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 interest of safety, we recommend that the FAIL-SAFE function 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, airbrakes extended, aero-tow release open, etc.).
