FailSafe

FailSafe methods include Hover, Go-home, and Altitude Go-home. Choose one as your failsafe method, which will

be triggered when the MC loses the control signal in one of the following situations:

Signal lost between transmitter and receiver, e.g. multi-rotor is out of the communication range, or

transmitter has failed, etc.

One or more connections of A, E, T, R, U channels between the MC and receiver is lost. If this happens

before take-off, the motors will not start if you raise the throttle stick. If this happens during the flight, the

LED will flash blue to warn you, in addition to the fail-safe method. If Hovering fail-safe method is configured

and U channel is disconnected, multi-rotor will auto land.

Also, you can select the Go-Home Switch item to start go-home (Go-home, and Altitude Go-home) by using a TX

switch during the flight, when selected during flight the LED will flash purple instead of blue.

The multi-rotor position before takeoff, including reference longitude, reference latitude and reference altitude, is

saved as home point by the MC automatically when you raise the throttle stick for the first time AND it has 6 or

more GPS satellites acquired for more than 8 seconds (

blinks once or no blinking >8secs)

After taking off, every time the aircraft recorded a home-point successfully the LED will blink Cyan quickly for

indicating.

THEREFORE:

to use any form of Go-home (including failsafe return home), you must make sure 6 or more GPS

satellites are acquired for more than 8 seconds (

blinks once or no blinking >8secs) before take-off, this will

assure correct recording of the Home position.

Go-Home Altitude

: Determined by the reference altitude and the FailSafe method chosen. That is, the go-home

altitude may be different due to fail-safe method chosen.



Hover

The aircraft will remain hovering when the fail-safe starts.
