WARNING
For safety, always set the fail safe functions.
■ Especially set the throttle channel fail safe function
so that the servo moves to the maximum slow side
for airplanes and to the slow side from the hovering
position for helicopters. Crashing of the model at full
high when normal radio waves cannot be received due
to interference, etc., is very dangerous.
■ If fail safe is reset by throttle stick movement, the fail
safe may be mistaken as an engine malfunction and
will be reset at low throttle and the model will continue
to fly. If you have any doubts, immediately land.

the servo to move to when the battery fail
safe function is activated, and tap the F/S
position button. This position is displayed in
percentage.

the Battery F/S release button. Now, you may

position, move the throttle stick to the point
at which you wish the B.F/S to be released.
