FailSafe
During an interruption / disturbance of the radio link between the transmitter and receiver the function FailSafe will
automatically be activated. The purpose of this function is to bring the ARF-MikroKopter, in case of a lost receiving
signal, back into the range of the transmitter to restore the receiver signal.
A reception failure can happen by exceeding the maximum range of the transmission path between the transmitter /
receiver.
When the connection is re-established again after using
FailSafe , the function will be automatically disabled and a
control of the copter is possible again via the transmitter.
If you are unable to restore the reception (transmitter failure due to dead battery, etc.), the FailSafe -function will perform
as follows:
•
Transmitter failure =>
The
ARF-MikroKopter will automatically switch the function Fa PositionHold ON and climb / fall for 5
seconds to a pre-set „ComingHome-Height“.
•
After the 5 seconds automatically the function "ComingHome" + Height regulator will be activated and the copter
will fly into the direction of the home position (Starting point).
Info: If the set „ComingHome-Height“ is not reached in the first 5 seconds the copter will climb / fall to the pre-
set height during the backflight.
•
If the reception cannot be restored during the backflight the ARF-MikroKopter will fly back to the home position
with the set time in the settings (max. 242 seconds). If the ARF-MikroKopter arrives at that point automatically
begins the descent flight with a fixed and unchangable rate of descent.
If there is a too much distance / height to the home position and can not be reached within the 242 seconds
it automatically switches to „emergency gas“.
Here the ARF-MikroKopter will not continue to fly to the starting position (home position) but goes at the
current position with a pre-set emergency gas into de descent flight The availability of nthis emergency gas
is another 24 seconds. After that the motors will switch off automatically.
Set the ComingHome Height for FailSafe
The „ComingHome Height“ can be done in the settings and in the window „ EasySetup “ by yourself.
Here you need to enter the height in which the copter will fly back in case of a reception failure
(see Pg. 20).
This height will be also taken if during a manual flight the function ComingHome will be activated.
The ComingHome Height helps to prevent not to fly into obstacles such as trees, houses etc. during the
automatic return flight.
