(4) The wires connecting the receiver to the flight controller are broken (unlikely).
When a radio Failsafe is triggered one of the following will happen:
(1) Nothing if the vehicle is already disarmed.
(2) Motors will be immediately disarmed if the vehicle is landed OR in stabilize or acro mode and the
pilot’s throttle is at zero.
(3) Return-to-Launch (RTL) if the vehicle has a GPS lock and is more than 2 meters from the home
position.
(4) LAND if the vehicle has:
no GPS lock OR
is within 2 meters of home OR
the FS_THR_ENABLE parameter is set to “Enabled Always Land”
If the Failsafe clears (i.e. transmitter and receiver regain contact) the copter will remain in its current
flight mode. It will
not
automatically return to the flight mode that was active before the Failsafe was
triggered. This means that if, for example, the vehicle was in Loiter when the Failsafe occurred and
the flight mode was automatically changed to RTL, even after the transmitter and receiver regained
contact, the vehicle would remain in RTL. If the pilot wished to re-take control in Loiter he/she would
need to change your flight mode switch to another position and then back to Loiter.
Copter also supports Battery, Ground Station and EKF/DCM failsafes.
You can check your Failsafe by performing the following tests with the MINI PIX connected to the
Mission Planner either via a USB cable or telemetry link. You can complete these tests without
plugging in your LiPo battery but if you do connect a battery you should first remove the propellers.
Test #1: if using the “Low
-
Throttle” method, ensure the throttle channel drops with loss of radio
contact
Ensure your RC transmitter is on and connected with the throttle all the way down and flight mode
set to Stabilize
The throttle (channel 3) PWM value should be approximately as in first illustration below. Its value
may be higher or lower but it should definitely be at least 10 higher than the value held in the FS
PWM field
Turn the transmitter off and the throttle PWM value should drop to be at least 10 below the FS PWM
field value (as in the second illustration below) below
Test #2: ensuring motors disarm if in stabilize or acro with throttle at zero
Switch to stabilize mode, arm your motors but keep your throttle at zero. Turn off your transmitter.
The motors should disarm immediately (red led will start flashing, DISARMED will be displayed in
the Mission Planner’s Flight Data screen).
