Protective function of the BL speed controller with the
battery connected:
If the flight battery is connected to the Arcus-Sonic's BL con-
troller, and the motor is not operated for a period of 2.5 mi-
nutes, a clear audible warning is emitted by the model. This
protective function is intended to remind the pilot to discon-
nect the battery from the controller after every flight.
If the model is allowed to glide for a long period without the
motor being switched on, this will trigger the audible warning.
You can switch it off again by "opening the throttle" once (in
which case the motor will not start running). The audible war-
ning has no effect on the servo functions or the receiver's
performance.

Airbrake setting
In the default setting the airbrakes (ailerons) extend down-
ward. This is the procedure for reversing this setting (ailerons
up):
Push the "MENU" button (right-hand trim lever) to the right
three times: "F-P" flashes. Now press the "ENTER" button
(left-hand trim lever): the current setting flashes.
One switch position is used for the neutral position of the ai-
lerons, which should be 50%. The other switch position de-
termines the travel of the airbrake function: if you set a value
above 50, the airbrakes (ailerons) extend up; if you set a va-
lue below 50, the brakes extend down.
Press "ENTER" to store the selected value, then quit the Se-
tup menu with "EXIT".
