Radio Failsafe Configuration & Test of Pixhawk Drone



In this video, I have shown on how to configure Mission Planner and FlySky-FS-i6S Tx for Radio Failsafe. The Radio FailSafe is mainly triggered if the Tx is disconnected from the Rx/Drone for any unwanted reason. The RTL mode will be initiated if the drone is more than 2m away from home and is on GPS Lock. Otherwise, the Land mode will be initiated. However, if the vehicle is armed and not taken off, then it will be disarmed on radio failsafe. The steps are as follows:

1. Configure Mission Planner & set FailSafe PWM.
2. Set the END Point on Channel 3 (Throttle Channel) to -120%.
3. Turn ON Failsafe on Channel 3 & Set the PWM to -120%.
4. Reset the Negative End Point on Channel 3 to -100%.
