ready) when the battery is plugged in, making it safer and more convenient
to handle the model before (and after) flight.
However,theOn/Offswitchisforshort-termuseonly(likewhenyouare
at the field). This is because even if the switch is in the off position, when
the battery is connected, some power is still being consumed by the ESC.
It is critical that you always disconnect the battery from the ESC when you
are done flying, when you are traveling to and from your flying destination,
and when the model is being stored. Leaving the battery plugged into the
ESC for an extended period of time, even with the switch in the off position,
could cause permanent damage to your battery as a result of overdischarging
(especially if you are using a Li-Po battery).
Connecting the ESC to the Motor
The three wires from your motor connect to the three female gold bullet
connectors on the ESC. The order of connection to the motor is not impor-
tant; you can plug any motor wire into any connector. When you test the
system, the motor runs backwards, you can simply unplug and switch any
two of the motor wire plugs connected to the ESC.
Mounting the ESC
Choose a location that has good airflow and offers good protection. The
smooth section on the bottom of the heat sink case is designed to accept
adhesive-backedhookandloopor2-sidedtape.Donotcoverthetopofthe
heat sinks as this will greatly reduce their effectiveness. Mount the ESC
withacombinationofhookandloop,2-sidedfoamtape,and/ortiewraps.
Starting Your Power System
1. Turn on your transmitter and ensure the position of the
 throttlestickissettoIdle/Off.
2.Plugthebatterypackintothecontroller.Youwillhear1lowlongtone
to indicate startup, then the respective number of medium-length mid
 tonestoindicatethecellcountoramusicaltoneforthe70%cutoff,
followed by 3 rising tones to indicate the controller is armed.
3. When you move the throttle stick upward, the motor will run. If you
continue to move the throttle stick upward to the full throttle (high
position), the motor will run faster. If you lower the throttle stick below
the start-up position, the motor will stop running.
4. Check servo motion as part of your preflight check. It is very
important you make sure linkages are free-moving with no binding.
 Remember,whenintheprogrammingmode:
Full Throttle = Stick Up
Idle = Stick Down

Entering the Programming Mode
1. With the battery disconnected from the controller, and the transmitter
turned on, first move the throttle stick to full throttle (>1.7ms)
position. Leave it in this position and then connect the battery to the
controller.
2.Waitfor5seconds,andtheESCwillgivetwosetsoffastringingtones
to indicate you have successfully entered the programming mode.
3.Onceyouhearthesetones,movethesticktocenter(between1.4and
1.7ms) for 5 seconds, and the controller will beep 1 time, indicating
you are now in Menu 1.
4. The controller will now wait 5 seconds for you to make your selection;
your programming options are either full throttle (>1.7ms) or idle
(<1.3ms).
5. When you have made a valid selection, the control will beep once with
a lower tone, and you can move the stick back to center for the next
 menuitem(2beeps,3beepsandsoon).Ifyoudonotmakea
selection within 5 seconds, the controller will move to the next
menu item.
6. If you want to make changes in the programming menus (see specific
instructions below) move the throttle stick to full throttle (>1.7ms)
position. You will have 5 seconds to make your selection.
7. If you want to advance to the next menu, allow the programming to
skip to the next menu after the 5 seconds have expired.
Programming Menu 1 – Voltage Cutoff
Usethisoptiontosetthevoltageatwhichthecontrollerwillshutdown

voltage. You will know your battery pack has reached auto cutoff when
you hear the motor “pulse” repeatedly.

make changes to the voltage cutoff programming.

advance to the first selection again.
IMPORTANT NOTE ABOUT 70% CUTOFF: This option will activate the soft
cutoff at 70% of startup voltage. For example, if your pack measures 15.0 volts
at startup, then the soft cut will occur at 10.5 volts. The 70% cutoff option will
check the startup voltage every time you plug the battery into the controller,
so beware of using partially charged packs, as the system cannot protect your
Li-Po batteries if you are using the 70% cutoff and connect a partially charged
pack. You will know your battery pack has reached soft auto cutoff when you
hear the motor “pulse” repeatedly. We recommend you land your model as
soon as you hear the motor pulse (indicating the pack voltage has dropped to
the cutoff voltage level) to prevent over-discharge of the Li-Po battery pack, and
to prevent sudden power loss.
