Control electronics has a protective relay for motor, which switches t h e e n g i n e s o f f automatically immediately with
blocking the rotors (e.g. after a crash). After an examination on eventuele damage these can be started b y m e a n s o f the
normal control command for engines (see pag e 28)

Stelt control electronics of the Quadrocopter to strong disturbances of the remote control signal firmly, tries it, to align
the Quadrocopter in a horizontal position.
If the disturbance is f u r t h e r present of the receipt, then the gas is gestelt to a value scarcely under hovering flight
(without ballast
)
and the Quad more rocopter begins a descending flight.
If the disturbance o f t h e r e c e i p t is past, the Modelpilot can i n t e r v e n e
at any time
b y own control commands and the
forced landing program is terminated.

The Quadrocopter constantly s u p e r v i s e s the tension of the attached Akkus. If this sinks during a certain period under a
critical parameter, then this is indicated by the LEDs.
The red LED and the green
LE D
flash shine continuously. This announcement can be switched off only by m a r k i n g the
Akkus out.
In order in the flight a weak accumulator, recommend it, occasio nal strong gas thrusts festzustelen to
accomplish itself. If the Quadrocopter reacts s l o w l y - a c t i n g and weakly, then a landing should be
accomplished and the accumulator be examined . With a longer continuous flying operation it is advisable
furthermore to examine also the LED displays by an occasional landing! This test is only with difficulty
recognizable alerdings due to the achievement.
