One or more connections of A, E, T, R, U channels between MC and receiver loses. If this happens
before take-off, motors will not work if you push the throttle stick; if this happens during the flight, LED
yellow light will flash to warn in addition to the failed-safe method.
Choose one method for your failed-safe function, Landing: or Go Home and Landing.
Landing: the aircraft will land after 6s hovering.
Go Home and Landing: Before takeoff, current position of multi-rotor will be saved as home point by MC
automatically when you push the throttle stick first time after 6 or more GPS satellites are found (
blinks
once or no blinking) for 8 seconds.
Notices:
When switch to Manual Mode or Atti. Mode, MC will disengage enhanced failed-safe mode, you can re-gain
control of multi-rotor.
Tips:
The following schematic shown is introduction for Go-Home and Landing.
STEP3: Intelligent Orientation Control
Without GPS, please skip this step
Forward Direction: Multi-rotor will fly along this direction when you push
the elevator stick.
Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By using Intelligent
Orientation Control (IOC), wherever the nose points, the forward direction has nothing to do with nose
direction:
In course lock flying, the forward direction is the same as a recorded nose direction. See the following
figures (Mode 2):
