10. Failsafe
Fail safe function – digital protection against radio interference. The safety electronic can detect reception of
a “false” or incomplete radio signal. E.g. due to a low transmitter battery or environmental radio interference which
reach the model, or if the model is out of the transmitter range. For protection against damage, servo
switches to the brake position and the model stops.
Setup:
1. Turn on the power of transmitter.
2. Connect power supply to receiver; LED on receiver should be solid.
3. Control the throttle trigger to make servo to “brake” or “stop” mode and remain for a while.
5. Setup is complete.
Testing:
1. Turn on the power of transmitter.
2. Connect power supply to receiver.
4. Servo which controlled by fail safe should go to brake modus automatically.
5. In case can be complete step by step with the above action, means setting is correct.
