Automatically selects cutoff voltage for 2- to 3-cell Li-Po batteries (6V/9V)*
Automatically sets correct motor timing
Safe power-on mode prevents accidental starts
Programmable braking (on/off)
1.5A Battery Eliminator Circuit (BEC) to power radio & servos
Includes gold bullet connectors for your motor
Specifications
Length: 36mm (1.4 in) Width: 24mm (.95 in) Height: 9mm (.37 in) Weight: 14 g (.5 oz) Cells: 6–12 Ni-Cd/Ni-MH; 2–3 Li-Po Continuous Amps: 20
* 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.
20-Amp Brushless
Speed Control
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 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:
1.
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.
2.
Move the throttle control on your transmitter to FULL throttle.
3.
Plug the battery into the ESC.
4.
Wait 5 seconds. You should hear a second beep after the initial power-on beep.
5.
Move the throttle control on your transmitter to the CENTER position.
6.
Wait another 5 seconds. You will hear another beep.
7.
Move the throttle control BACK to FULL throttle and wait for another beep.
8.
Move the throttle control back to the CENTER position. You will hear three beeps.
9.
To turn the brake ON, move the throttle BACK to the FULL throttle position.
10.
To turn the brake OFF, move the throttle DOWN to the OFF throttle position.
11.
Disconnect the battery. The brake is now programmed.
