Safety Devices

The QuadroCopter has a range of safety devices which protect the model from damage and/or should reduce possible
damage to a minimum. The protection mechanisms are identified by LED indicators. Also see the next chapter 12.
a) Motor Protection
The control electronics has a motor protection which immediately switches off all motors if one rotor is blocked (e.g.
after a crash). After possible damage has been checked for, the motors can be restarted using the normal control
command „starting the motors".
b) Emergency Landing
If the control electronics of the QuadroCopter detects too great interferences, it tries to realign the QuadroCopter in a
level position.
If interference of the receiver continues, the throttle is set to a value just under hovering (without rear weight) and the
QuadroCopter begins its descent.
When the interference of the receiver is over, the model pilot can give another control command and the emergency
landing programme is terminated.
c) Low Voltage Monitoring
The QuadroCopter constantly monitors the voltage of the connected battery. If it falls below a critical level over a
particular period of time, this will be indicated by the LEDs.
In this case, the red LED flashes and the green LED will be permanently lit. This indicator can only be switched off by
disconnecting the battery.
In order to detect a low rechargeable battery during flight, it is recommended that strong throttle thrusts be carried out
from time to time. If the QuadroCopter responds slowly and weakly, it should be landed and the rechargeable battery
should be checked. Due to the performance, this test is, however, difficult to realize.
In the case of a long, uninterrupted flight operation, it is recommended to also test the LED indictors through time to
time landing!
Practical advice:
To avoid damage to the QuadroCopter from crashing due to undervoltage and/or to the rechargeable battery due to
total discharge, we recommend that you always observe the low voltage light signals. As the integrated LEDs only
flash in one direction, we also recommend installing the LiPo Saver (Conrad item no. 230327). The LiPo saver warns
you of impending low voltage by light signal. Place the LiPo Saver on the appropriate position on the QuadroCopter
and connect it to the battery via, e.g., the balancing connector.
