Extreme-Heli regulator is dual linear regulator consisting of hybrid
components with the power supply scheme by reboost power bus, which is
high-end grade regulator to satisfy both utmost Extreme 3D flying and
F3C to pursue perfect stability for high-class users.
regulator, is actively applied with rapidly changing RC environment
such as popularizing trend of Extreme 3D flying, becoming bigger of the
body and high performance of the servo from the product design stage,
has been developed to focus on the quality and stability of power and
the improvement of transient response of entire power system instead of
traditional method which uses simple current capacity as a measure for
designing a regulator. In addition, the safety as well as user's
convenience are secured to add the alarm function for low voltage of
the receiver battery.
Power supply scheme by the Reboost power
bus uniformly distributes power required for CCPM servo channel to
guarantee stable property of the body, and can perform faithful Gyro
function with excellent blocking effect against external noise such as
reverse electromotive force of CCPM servo due to direct connection
between the gyro system and RX.
It has passed various
electronics countermeasure test and long-term field test, and optimized
to tune with extreme operating environment as the project product even
through the test for extremely hot weather in a desert region.
Therefore, it should be the masterpiece of regulator to find
differentiated performance other than any products experienced before.
What is the Reboost Power Bus?
a servo and maximization of performance to rapidly supply the voltage
and current required for a servo of each channel by the shortest path,
maximum capacity using a regulator as a hub of power system instead of
traditional scheme supplying power for a servo via a receiver.

As the world's famous products have kept just DC-DC voltage regulator
of linear type, this product is also dual channel linear regulator that
wouldn't fundamentally generate switching noise and ripples contrary to
switching-type regulator and has superior voltage stability, current
supplying capability, and transient response against radical load
variation. Therefore, it is enable to safely apply to PPM, PCM schemes
as well as all system including 2.4GHz.
◆ Total electric
current consumption during extreme 3D, F3C flight approaches 8A. Thus
traditional power supply scheme has limits not to effectively operate
servos. To improve it, this product is applied with the reboost power
bus scheme based on new concept that a regulator directly supply power
to a servo for each channel instead of passing battery power through a
◆ Contrary to existing products that two same
regulators are packed in a case, it has manufactured that each
electronic device can achieve the best performance with designing
hybrid type to use each other output component for CCPM servo's
circuits emphasizing the power and responsibility, RX and Gyro's
circuits emphasizing the voltage stability and noise-free.
Output voltage setup is designed to choose required voltage among five
preset voltages of 5.2V, 6.0V, 6.8V, 7.4V, 8.4V(Bypass) by four-stage
DIP switch. Therefore, additional device to measure the voltage is not
required for voltage setting and everyone can easily and quickly set
◆ Low voltage alarm circuit is embedded to
guarantee user's convenience and safety. According to the type of
battery or the preference, alarm voltage can be arbitrarily
established(7.3V or 6.5V) and chosen whether or not to use.
If the voltage of main battery falls below the voltage established for
low voltage alarm, low voltage alarm circuit begin to operate. Both
LOW/BATT LED display and buzzer on main unit are simultaneously active,
external LED board(GDB-1010 option), mounted on the fuselage,
distinguishable even in flight is equipped. Three high-luminance LEDs
on external LED board quickly flicker on and off in the case of low
voltage so that it is possible to immediately recognize low voltage
alarm condition even in day long flight.
◆ There are
input/output ports for four channels. Three servos for CCPM as well as
throttle servo can supply the power optimized to servo
specification(4.8V or 6.0V), and the voltage optimized to each servo
even for system using 4.8V mixed with 6.0V servo.
◆ It is
supported to use 7.4V HV servo. If output voltage is setup to 7.4V or
8.4V(Bypass), it is able to achieve more stable power supply and
transient response than 7.4V battery direct connecting scheme to
perform the buffer regulator function along with capacitor circuit.
If the battery voltage is lower than the regulator setup voltage,
safety accident from shut-down bypassing the battery voltage to the
output voltage can be prevented.
4. Switch connection
Fail-safe-on Pin-flag contactless switch to SW port of main unit. Three
models of pin type(GSB-1010P), slide switch type(GSB-1010S), and
connector type(GSC-1010) are supported, and user can choose one type
depending his/her preference and convenience. Pin typed switch is
supported as basic type at the factory. If Pin-flag on the switch board
is pulled out, power is turned on.
☞ Switch board(GSB-1010P)
could use double-sided foam tape or cable tie, or has a hole to fix
with 3mm bolt in the middle of the switch board. Fix tightly with it.
Contactless switch consumes very small current as standby current in
off status. Therefore, a battery must be kept separate from connectors
of a regulator for long term storage more than a month.
Caution and reference
5. Battery connection
input basically supports DINS connectors. Connect a battery to
precisely check +/- polarity of male connector. At this time, if switch
is on-state, short sound like 'peep' from buzzer could be listened(same
as switch is on). This is the signal that low voltage alarm is normally
operating. Female connector is the connector for charging and checking
voltage. For dual battery, user would exchange female connector for
male connector to connect the battery.
☞ Must be careful with
polarity during exchanging connectors. If +/- polarity of a battery is
inversely connected, internal circuit should be destroyed.
6. Receiver & Servo channel connection
four JR typed female-female extension cable enclosed in the product to
the channel of the receiver and the RECEIVER channel of the regulator.
The regulator supplies 5.2V of power to the receiver via connected
cable, and receives the signal of corresponding channel to bypass to
the servo channel of the regulator in return. The servo connects to the
servo channels of the regulator corresponding to 1~4 channels. As a
result, the connection for the reboost power bus scheme that the servo
is supplied the power from the regulator and the signal from the
receiver is completed.
☞ The case that the servo
specifications are the same : If operating voltage specifications of
four channel servos are all the same, all four channels are connected.
The case that the servo specifications are different : If it is used
three CCPM(6.0V) and a throttle servo(4.8V) mixed with devices such as
governor, the throttle servo should be used to directly connect with
☞ Power(5.2V) to output to the receiver and
power(5.2~8.4V) to output to the servo channel are independent circuits
to completely separate. Thus, if the receiver is improperly connected
to the servo channel of this product mixed with cables of the gyro or
governor, the failure of the devices could be occurred so that it must
7. Using AUX channel
Use to connect the LED
board(GDB-1010 option spec) for low voltage alarm. In addition, if +/-
terminals of AUX terminal is used, the same voltage as the servo
channel could be additionally used.
Signal terminal : low voltage alarm output
+ terminal : the same voltage output as servo channel
- terminal : common ground
