The RC EYE 450 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. For this,
please observe the following chapter “12. LED Displays” on page 27.
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”.
emergency landing
If the control electronics of the RC EYE 450 detect too great disturbances, it tries to realign the RC EYE 450
in a level position. If disturbance of the receiver continues, the throttle is set to a value just under hovering
(without rear weight) and the RC EYE 450 begins its descent. When the disturbance to the receiver is over,
the model pilot can take action using their own control command and the emergency landing programme
is terminated.
low voltage monitoring
The RC EYE 450 constantly monitors the voltage of the connected battery. Should this fall below a critical
level over a particular time frame, 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 battery during flight, it is recommended that strong throttle thrusts are carried out
from time to time. Should the RC EYE 450 respond slowly and weakly, it should be landed and the 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 indicators
through time to time landing.
Practical advice: To avoid damage to the RC EYE 450 through crashing and/or due to low voltage of the
battery through total discharge, we recommend that you respect the low voltage light signals without fail.
