FAIL-SAFE point you previously stored in the FAIL-SAFE set-up. Make sure you set the FAIL-SA-
FE 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.).
1. Turn On the transmitter and receiver
2. Check the correct operation and place control stick or control toggle of transmitter to fail-safe
position.
3. Press and Hold Link button in the receiver in 6 seconds.
BLUE LED will be blinking start slowly and then blinking rapidly.
4. Once BLUE LED change to solid BLUE, Fail Safe is successfully completed.
5. Please turn off the transmitter to check the operation.
