Programming of the flight controller
a) Turning the braking function on/off
The flight controller uses an integrated braking function, automatically braking the connected
electric motor as soon as the control stick for the revolution speed is set to the "motor off"
position. This ensures that the folding propeller of an electric glider model neatly folds onto the
fuselage and does not run on due to "autorotation".
Attention, Important!
When using the flight controller in an electric model helicopter, the braking function
has to be turned off!
In order to turn on/off the braking function, proceed as follows:
• First disconnect the accumulator from the flight controller.
• Turn on the sender.
• Push the control stick for the motor control to the position for maximum motor speed.
• Only then connect the accumulator to the flight controller.
• The motor will then make some signal sounds ("do-re-mi-di").
• After a few seconds the motor will make three short beep sounds ("di-di-di") while the LED
simultaneously flashes 3 times.
• Push the control stick for the motor control to the "motor off" position, The motor will make
one long beep sound ("diiiiiiii") and the LED is lit 1x.
• Now the braking function is turned off.
• The LED flashes slowly in order to indicate that the flight controller now can be used.
• If you slowly move the control stick away from the "motor off" position towards full throttle,
the motor will start running.
b) Settings of the motor-cut-off
When connecting the flight accumulator, the flight controller measures the present accumulator
voltage and calculates the cut-off-voltage used to turn off the motor to protect the accumulator
from deep discharge.
Attention, Important!
Only reconnect a fully charged flight accumulator to the flight controller, other wise,
there is the danger of deep discharge of the accumulator!
A cut-off value of 65%, 70% or 75% of the initial value of the accumulator voltage can be set.
If the flight controller measures a voltage of 8.4V, e.g. when connecting a fully charged double-
cell LiPo flight accumulator, the flight controller then turns off the motor (depending on the
programming of the cut-off settings) either at 5.5V (65%), at 5.9V(70%) or at 6.3V (75%).
In order to set the motor cut-off, proceed as follows:
• At first disconnect the accumulator from the flight controller.
• Turn on the sender.
• Push the control stick for the motor control to the position for maximum motor speed.
• Only then connect the accumulator to the flight controller.
• The motor rakes some signal sounds ("do-re-mi-di").
• After a few seconds the motor will then make three short beep sounds ("di-di-di") and the LED
will flash 3 times (programming of the brake, see above).
Please wait!
• After a few seconds the motor will make five short beep sounds ("di-di-di-di-di") and the LED
will flash 5 times.
• Now select the desired cut-off value using the control stick for the motor speed.
65%
move the control stick to 0-33% of the control stick travel (motor-off position)
70%
move the control stick to 33-66% of the control stick travel (centre position)
75%
move the control stick to 66-100% of the control stick travel (full throttle); or leave
the control stick in the full throttle position
• The motor will make one long beep sound ("diiiiiiii") and the LED is lit 1x.
• Move the control stick to the "motor-off" position.
The LED flashes slowly in order to indicate that the flight controller now can be used.
If you slowly move the control stick away from the "motor off" position towards full throttle,
the motor will start running.
