Central Control Unit Instructions
A) ON/OFF (Power Switch): Hold this button down to turn
on the power.
Caution: Even if power is turned off, the LED remains on
which indicates power is connected to this controller.
Make sure to always disconnect the receiver battery after a
day of flying; otherwise the battery will be slowly exhausted
by this control unit!
NOTE: The BATT connection is only used for set up and testing the Black Box when no
Receiver Battery is connected. It is not intended to be used in normal operation.
B) Manual button
B-1) Long press- Holding this button down will retract the gear.
NOTE: This function only works when the transmitter is not on. This is very useful for bench
operation, etc.
B-2) Short press-Tap this button to turn the landing gear Failsafe on or off. When it’s turned
on, failsafe (F/S) LED is green and height is displayed in screen.
Example: When the screen displays 002, the height setting is at 2 meters. Press again to turn
off this function. Screen reads “OFF”.
NOTE: Refer to section “C-4)” to change the height setting value.
The landing gear failsafe is a method of protecting your airplane from an accidental retract of
the gear while it is sitting on the ground below the setting (ex: 002: below 2 meters). If the
plane is sitting on the ground and a retract command is given, the gear will not retract. If you
want to bypass this feature, toggle the F/S off by tapping the “Manual” button, this will turn the
F/S LED red.
C) Setup button
C-1) Short press- Tap this button and the screen will display “PSI”, “V” (Voltage) and “RPM”.
The corresponding LED of each function will be on when it is displayed.
Note: BVM does not use the RPM function of this controller.
C-2) Long press- Holding this button down when “PSI” is displayed will enter the “Pressure
Loss Protection Setup”. This feature will deploy the landing gear in the event of a leak.
Increase the feature by 10PSI with each press, max. is 60PSI. Hold the “SETUP” button
down and the setting will be saved. Press the “SETUP” button again and “V” will be
displayed.
