G Good GPS Reception (Outer Lights of GPS
Indicator Light Are ON)
1 When radio signal interference occurs, the inner
and outer lights of the red YACS warning lights
will flash alternately, and the system will apply
the brake and force the helicopter to hover
regardless of the flight mode. Then, the helicop-
ter will automatically start descending slowly. If
the control radio signals recover while the heli-
copter is descending, the flight mode will switch
automatically to operator control. For this rea-
son, calmly move all the sticks on the transmitter
to the neutral (center) position, and wait for the
signals to recover.
2 If the helicopter is forced to land because the
radio signals have not recovered, the engine is
brought to idle.
Depending on the terrain, weather, and flight
conditions, the helicopter could overturn. If the
helicopter overturns, never approach the heli-
copter, as the engine speed might not decrease.
3 After a forced landing, turn the throttle to the
slowest position and wait for the radio signals to
recover or the engine to stop.
4 If the radio signals do not recover after 1 minute
from the time the radio signal interference
occurred, the engine will stop automatically.
After the rotor has come to a complete stop,
approach the helicopter and turn OFF its main
switch.
