XTERNAL SWITCH
The FALCON ESC allows you to install an external switch if
needed. By default the switch is not present, so that the
speed controller/BEC turns on immediately after
connecting the flight battery.
You can specify the type of switching element in the
Common Setting – Switch Type
:
Mechanical (default) – the switch shorts the yellow (signal) and brown (ground) wires of the
Switch/Button cable.
An inverted logic is used, so that the ESC stays turned on if the switch is left open.
Button/Hall – first long press turns on the ESC; second long press turns it off. The LED indicates on/off
state and blinks if the magnet (or button press) is detected. The Hall sensor can be bought as an ESC
accessory.
Electronic – allows you to install an external electronic switch (Touch Switch, RC Switch etc.). In this
case, the switching device is always powered and the logic level of the signal wire specifies the on/off
state to the controller.
Note:
Please pay attention to the parameters of an external switch before connecting. The signal wire uses a
3.3 Volt logic with a weak pull-up. The power supply from the ESC is rated 10V with maximum current 30mA.

ROPELLER POSITIONING
The positioning feature allows moving the motor/propeller to the exact position required for safe landing, or
which is just comfortable for further flying. With just a few external components (Hall-sensor and a small
magnet) you can enable this feature and prevent the risk of damaging your propeller during landing. The
magnet needs to be properly fixed to the rotating part (either motor or the propeller), and the Hall-sensor has
to be located in the fuselage, so that the magnet matches the Hall-sensor at the target propeller position. After
enabling the positioning feature in the menu (Prop Position =
Hall Sensor
), set also the Positioning PWM, so that
the motor spins slowly but smoothly. You may also change the duration of actively held motor position
(Position Hold Time) which is applied after the correct position is found. The position-hold feature is useful in
case of retractable engine since it doesn’t allow propeller to be moved while retracting.
Connect the Hall-sensor of the propeller positioning function to the
IN-B
port of the controller.
