Mercury User Manual - May 2010
SMALLEST IN ITS OWN CLASS ...A break through technology that display real live information through Bluetooth enabled cell-phone
Thank you for purchasing the mercury,
worlds first electronic speed controller (esc) that can
stream measured and calculated current, voltage, rpm,
throttle level, temperature, watt and mah data right to your
cell-phone1. By eliminating awkward wires and bulky display
panel, Mercury is the smallest and lightest in its class, and it
can easily fit into your electrical powered radio control
model.
When within range2, hobbyist can instantly get the critical
electrical parameters hassle free using their bluetooth
enabled java cell-phone, even when they are away from their
model and whilst their models are still in action.
e.g. you are 10 - 20 m away from your helicopter, you tach its
head-speed by live view its rpm right to your cell-phone
without tachometer ...
Introduction
1. Support standard JAVA MIDP 2.0 or below, and Bluetooth access via BTAPI
2. Depended on cell-phone model (as tested with Motorola SLVR L7, The range is up to 80M)
rpm window provide liveview head-speed of yourhelicopter, tach your
head-speed with your cell-phone while you are awayfrom it 10-20 meters ...

The mercury can save up to 27 hours of information by its
internal one mega byte memory. User can download their
logged data to their computer using raclink cable (usb data
link cable sole separately) and manage the data and
performance charts with the included raczing pc client
software.
the mercury logged and live view data can be use in
difference ways to enhance your electrical-powered rc
model experience as follow :
flight data recorder,
battery health monitor,
tach your head-speed for governor mode in one place
flight-plan tools, and
system diagnostic and optimization equipment.
The mercury onboard logger and bluetooth module provides critical
information in a revolutionary way to give radio control model hobbyists a new way to fine-
tune the performance of their electrical powered model for things such as :
maximize flight time.
optimize gearing and propeller size and shape on power consumption and battery
currents.
esc and motor efficiencies through knowledge of current flow through an esc and
motor.
improve battery life by monitoring battery health.
eliminate potential risk of damaging components with peak
current data.
Benefits
The mercury delivery 50 amp3 rated current by n type mosfet with low
internal resistance, built-in logger measures and records current, voltage, rpm, throttle
level and temperature over time, then uses these measurements to calculate the maximum
power (watt) and capacity used (mah). real-time information as to live and peak current, rpm,
temperature, throttle, live and used voltage, current and maximum power (watt), as well as
existing and accumulated capacity used (mah) is transmitting using bluetooth technology.
User can use their cell-phone to read these data in real-time for their pleasure or to fine-
tune their electrical powered model.

Read these instruction before use
Before installing your mercury esc, take a moment to look it over. The input battery side has
a black and red wire along with a throttle lead. The motor side has three wires with color
black, white and red. The black and red wires of your mercury esc must connect to your
battery packs red and back with correct polarity (red wire of esc connect to red wire of
battery pack and black wire of esc connect to black wire of battery), reversed polarity may
damage your mercury esc without warranty cover.
The three wires from your motor connect to the three wire from mercury esc output. The
order of connection to the motor is not important; you can plug any motor wire to any wire
of mercury esc, in case of motor runs reverse (not your desire direction) just simply switch
both outside wires.
Always start your system in the appropriate sequence
1. be sure to plug the throttle lead into the throttle channel of your receiver.
2. turn on your transmitter (some 2.4 g radio need to power up receiver then followed by
transmitter) and set the throttle stick to mid throttle or higher.
3. connect the power battery to the mercury esc. The esc will remain disarmed and will not
operate until zero throttle is detected.
4. When you are ready to fly, move the throttle stick to its break or lowest position.
When battery is connected to mercury esc in step 3 above, mercury esc will emit 3 short
tones immediate followed by the number of tones indicate that it is power up and number of
lipo cell is counted e.g. when 3 cell lipo is connected, esc will emit 3 short tones followed by
another 3 short tones, and both red and green leds blink indicate mercury esc is unarmed
and onboard bluetooth is ready for pairing or connect respectively, the middle yellow led
stay on indicate data flash is ready to record data.
The mercury esc will not delivery power to the motor until the throttle stick of your
transmitter is moved to its break or lowest position to arm the esc, when armed mercury esc
will emit 6 short tones and red led will be turned off.
Now yellow led is stayed on, when throttle stick is leave its break or lowest position or
throttle is applied, yellow led go blink indicate data is being written to onboard data flash.When bluetooth mobile phone is connected, green led will be turned off.

Programming ESC
Mercury series esc offer programming via transmitter stick or usb link (sole separately) for
advanced features such as helicopter modes.
When entered into programming mode, mercury esc
will emit red led and beep tones to indicate its
current setting and option, by moving your
throttle stick to either full or break position
for answer yes or no.
When answer either yes or no, mercury esc will emit beeps and flashes repeatedly
to indicate the answer is accepted, then move your throttle to middle
position to proceed for next setting or option.
e.g. when entered into programming mode, it will single flash / beep and followed by
another single flash / beep repeatedly to indicate it is in setting 1 option 1 (cutoff voltage -
auto lipo), move your throttle stick to answer yes or no, if answer is yes, mercury esc will
emit beeps and flashes to acknowledge your answer is accepted, then move the throttle stickto the middle position to proceed to next setting (double flashes / beeps followed by single
flash / beep for next setting current limiting - 45a), if answer is no, mercury esc will emit
beeps and flashes to acknowledge your answer is accepted, then move the throttle stick to
the middle position to proceed to next option (single flashes / beeps followed by double
flash / beep for next option cutoff voltage - 4.0v cutoff).
If you want to program some of the features without go through the rest features, you can
program it by move your stick to full position and have the acceptance tones then exit by
disconnect the mercury esc power.

Enter Programming Mode
1. connect motor to the mercury esc in order to hear the programming beeps. Make sure
the mercury esc is unpowered, turn on the transmitter and move its throttle stick to
full throttle or highest position. For some 2.4g transmitter you may need to power on
receiver before turn on transmitter.
2. connect battery to the mercury esc, it will beep its initialization tones (3 short tones)
and emit single flash on red led repeatedly.
3. move the transmitters throttle stick back to middle position, the mercury esc will beep
its acknowledge tone (3 short tones) and emit double flashes on red led repeatedly.
4. move the transmitters throttle stick back to full or highest position, the mercury esc
will beep its acknowledge tone (3 short tones) and emit triple flashes on red led
repeatedly.
5. move the transmitters throttle stick back to middle position, the esc will beep its ready
tone (9 short tones) followed by single beep and emit single flash on red led repeatedly.
Now mercury esc should emit single beep / flash followed by another single beep / flash

raczing Mobile Client
Mercury esc provides real time data streaming into any bluetooth equipped java cell-phone.
Download and copy the software to your cell-phone via either bluetooth or data cable as a
normal java game and install accordingly. Since installation methods for java applets vary
from brand to brand, they may display entire different dialog; e.g. nokia phones allow
copied java program to run directly while sony ericsson phones require you to install
copied java program to another folder ! The following example is based on a sony ericsson
k770i model.
1. download raczing mobile client from raczing website and copy to your cell phone folder.
2. turn on your cell phones bluetooth.
3. run (some cell-phones need installation first) the raczing mobile client from where it is
saved or copied.
