will greatly reduce its effectiveness. Mount the ESC with a combination of

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74%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 to make sure linkages are free-moving with no binding.
 Remember,whenintheprogrammingmode:
Full Throttle = Stick Up
Idle = Stick Down
The default settings (from the package) for your E-flite 40-Amp Pro
ESC are as follows:
 •Voltagecutoffsetat74%
 •BrakesettoOff
 •Timingsetat15degrees
 •ThrottleInputRangesetat1.2msto1.8ms
 •Start-upRate(AccelerationDelay)setat0.25seconds
 •PWMFrequencysetat8KHz
 •OperatingModesettonormal(airplane)
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
the motor to prevent damage to your battery when it reaches the cutoff
voltage. You will know your battery pack has reached auto cutoff when
you hear the motor “pulse” repeatedly.
1. Move the throttle stick to full throttle (>1.7ms) position to
make changes to the voltage cutoff programming.

program selection or leave in full throttle for 5 seconds to
advance to the first selection again.
IMPORTANT NOTE ABOUT 74% CUTOFF: This option will activate the soft
cutoff at 74% of startup voltage or 9.2V, whichever is higher. For example,
if your pack measures 16.8 volts at startup, then the soft cut will occur at
12.4 volts. The 74% 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
74% 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.

Programming Menu 3 – Timing
The default setting is 15 degrees. As a general rule, lower pole count
motors use lower timing and higher pole count motors use higher timing.
Please refer to your motor instructions and specifications for an indication
of the number of poles.
