The parts that are likely applicable:
Tip: If the ESC sounds a continuous double beep
after the ﬂight battery is connected, recharge or
replace the battery.
If you accidentally connect the battery while the
throttle is fully opened, a musical tone will sound
after 5 seconds and the ESC will enter programming
mode. Disconnect the battery immediately.
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
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
1.6ms), and the controller will beep 1 time, this indicates menu item 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
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
6. Please note that if you do not need to program every menu item, you
can simply exit the programming mode after you have made the
required selections. You can do this by moving the throttle stick
straight to Idle, after making your selection, or leaving it in the Idle
position if you made a no selection (for approximately 8 seconds), until
you hear one set of 3 medium length rising tones that indicate the
controller has armed the motor, or by simply unplugging the battery.
Remember, when in the programming mode:
Full Throttle = Stick Up
Idle = Stick Down
The default settings (from the package) for your
E-flite 10-Amp Pro ESC are as follows:
• 3S (9V) auto cut-off for Li-Po
• Brake Off
• 4-pole and greater timing (outrunner or 6-pole motors)
• Throttle input range set to Auto Select Mode
Programming Menu 1 – Voltage Cut-off
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 cut-off
voltage. You will know that your battery pack has reached auto cut-off
when you hear the motor “pulse” repeatedly.
1. 3S Li-Po voltage cut-off – Full Throttle
2. 2S Li-Po or Ni-Cd/Ni-MH voltage cut-off – Idle
3. 70% Smart Cut soft cut-off (See below for Smart Cut information)
NOTE: To access the 70% Smart Cut option, leave the stick at full throttle for 7 seconds while in menu item 1, until 7 beeps are heard, then continue through the program normally. This option will activate the soft cut-off at 70% of startup voltage. For example, if your pack measures 10.0 volts at startup, then the soft cut will occur at 7.0 volts. The Smart Cut 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 Smart Cut and connect a partially charged pack. You will know your battery pack has reached soft auto cut-off 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 cut-off voltage level) to prevent over-discharge of the Li-Po battery
pack, and to prevent sudden power loss.
Programming Menu 2 – Braking
This option gives you the choice to have the ESC stop the propeller during
flight (Brake on) or allow it to windmill (Brake off). Use the brake-on option
1. Brake Off – Full Throttle (>1.7ms)
2. Brake On – Idle (<1.3ms)
Programming Menu 3 – Timing
Please refer to your motor instructions and specifications for an indication
of the number of poles.
1) 4 pole and greater motors timing mode – Full Throttle
2) 2 pole motors timing mode – Idle
Programming Menu 4 – Throttle Input Range
This option is to allow for proper operation of the ESC with many different
radios on the market. Most radios, and all the computer radios we have
tested, work well with the auto-set option, but some radios have a wider
output range, and may give a more linear response with the 1.1 to 1.9ms
range. If you feel there is too much “dead” area in the stick movement
near Full Throttle, try adjusting the end points in your radio, or change to
the wider input range. Be aware that if these settings are not correct, it
may be impossible to arm the controller. If this happens, return the input
range setting to the default auto learning setting.
The auto setting option learns the minimum position of your throttle
(between 1.1 and 1.3ms) and stores this value at each startup, and then
adds a value of 0.6ms for the full throttle setting.
1. Throttle Range 1.1ms to 1.9ms – Full Throttle
2. Auto Select – Idle
The controller will beep continuously if the input voltage is below the cut
voltage (beep...beep...beep) when the battery is connected. Check the
voltage of the battery pack to see if it is correct, or the programmed cut-off
setting if the input voltage is set incorrectly for the voltage of the pack
If you have trouble arming the controller (and the throttle trim has been
set to minimum), enter the programming mode and try the auto setting in
Programming Menu 4 to see if it helps correct your problem. If it is a
computer radio, you may alternatively increase your high and low throttle
ATV (endpoint) percentages.
Some systems including many Futaba systems may require the throttle
channel to be “reversed” for proper operation.
