PLEASE READ THESE INSTRUCTIONS IN THEIR ENTIRETY BEFORE USE
Before installing your ESC, take a moment to look it over. One side has a black wire, a
red wire and a servo plug. The other side has three gold plugs.
The wires connect to your power battery. The servo plug connects to the throttle
channel on your radio receiver. YOU MUST ENSURE THAT YOU CONNECT THE BATTERY
PROPERLY. The red wire connects to the red wire on your battery pack, the black wire
to the black wire on your battery pack. If the wires are reversed, the ESC may be
damaged. Reversing the battery will void your warranty, so always double-check this
connection. Solder a connector to the speed control that matches your battery
connector. We suggest a set of Dean’s Ultra Plugs (WSD1300). Make sure you install
the male connector on the ESC and the female on your battery.
The three wires from your motor connect to the three round gold connectors on the
ESC. The order of connection to the motor is not important; you can plug any motor
wire into any connector. If, when you test the system, the motor runs backwards,
reverse any two of the motor wire plugs. It is usually easiest to switch the outside
wires. If your motor does not come with connectors, solder the three male gold bullet
connectors (EFLA241) included with your ESC to the three motor wires.
NOTE: If your brushless motor (such as Hacker E-Series motors by E-flite
™
) does not
have silicone insulated wire leads, you should solder the included pieces of silicone
wire to your motor leads first (use heat shrink tubing). Then you can solder the
silicone wire leads directly to the female gold connectors on the ESC (be careful not
to desolder the connectors from the board) or solder the male connectors to the
silicone leads and plug into your ESC.
Before first use, please refer to the chart on the front of this card for BEC usage and
cutoff voltage guidelines. You must follow these guidelines for safe operation.
Plug the receiver wire into the throttle channel of your receiver before testing the
ESC. First, turn on your transmitter. Then, plug the power battery into the ESC.
Always start your system in this sequence. Your motor will beep when you plug the
power battery in, and your servos should move. Check servo motion as part of your
preflight check. You must always use a fully charged battery pack. It is very important
you make sure linkages are free-moving with no binding. When you are ready to fly,
move the throttle stick to the low position. The motor will beep twice indicating the
system is armed. You are now ready to fly.
Changing the brake programming:
To turn the prop brake on or off, follow this sequence:
Disconnect the ESC from the battery, and leave disconnected for at least 30
seconds to allow the speed control to reset. Turn your transmitter ON.
Move the throttle control on your transmitter to FULL throttle.
Plug the battery into the ESC.
Wait 5 seconds. You should hear a second beep after the initial
power-on beep.
Move the throttle control on your transmitter to the CENTER position.
Wait another 5 seconds. You will hear another beep.
Move the throttle control BACK to FULL throttle and wait for another beep.
Move the throttle control back to the CENTER position. You will hear
three beeps.
To turn the brake ON, move the throttle BACK to the FULL throttle position.
To turn the brake OFF, move the throttle DOWN to the OFF throttle position.
Disconnect the battery. The brake is now programmed.

* You must always use a fully charged battery pack in order to ensure proper cutoff
voltage is selected. Once a battery pack has been partially discharged and unplugged
from the ESC, reconnecting it before fully recharging the pack may result in the
incorrect voltage cutoff being selected, potentially causing damage to the pack.

If you wish to disable the BEC (required if you’re using more than 10 cells), you must
first remove the red receiver wire and then insulate properly to prevent shorting.
