*Size and weight are for reference and may vary
BEC: stand for "Battery Eliminator Circuit" A BEC is an extra circuit in the ESC that eliminates the need to power receivers and servos with another battery. Since these components use a lower voltage (5v) than the ESCs input voltage, standard BECs use a linear regulator that steps down voltage by converting the voltage into heat. The higher the battery voltage, the more heat generated and the less effective the BEC is. Due to this inefficiency, our ESCs use an SBEC/UBEC, which is a more efficient BEC, as explained below.
SBEC (Switching Battery Eliminator Circuit) uses an efficient switching regulator to step down the voltage and doesn't convert the difference in voltage to wasted heat. SBECs are an improved design of BECs.
UBEC: Another name for SBEC
OPTO: The ESC doesn't have a BEC, and a separate power supply is required to power the receiver and other components.
S: Number of cells in a battery, not to be confused with c (charge & discharge rating). Standard LiPo batteries are referenced at 3.7v per cell, which is the average output voltage over the batteries cycle (3.2v dead and 4.2v fully charged)

ESC's Maximum RPM
480,000 / # poles = maximum RPM, refer to the chart below. The CLASSIC ESC works with almost every motor, so you shouldn't need to worry about this. Rather hook the motor up and see if it works at full speed. Motors spin faster when they are unloaded, so you may find your motor works just fine when the motor is installed in its application. E.g., a propeller is installed.
Poles: The number of magnets in the motor.

Advanced Explanation
ESCs, take DC power, and output timed AC power to advance the motor's rotation. ESCs have three output wires and switch between a different set of two of the three wires to make a circuit (3-phase AC Power). The ESC can switch the output power up to 480,000 times per second. The more poles (magnets) in the motor, the more times the ESC has to alternate the output power to turn the motor one revolution. Therefore, the maximum RPM the ESC can support is decreased by the number of magnets in the motor.
Kv: Used to calculate the motor's maximum RPM. KV * Input voltage = maximum RPM.

The ESC is plug-and-play, and the settings should not need to be changed (programmed). Though, we recommend doing a throttle range calibration to set the minimum and maximum throttle points to ensure smooth and accurate throttle control. If you do want to change the ESC's settings, see How to Change the ESC's Settings (Programming) for more information.

- Put the transmitter's throttle in the maximum throttle position.
- Power the ESC.
- Wait about 5 seconds for the motor to start sounding a short beep. The ESC repeats these short beeps a total of four times. WHILE the motor is making these short beeps, proceed to step 3.
- Move the throttle to the minimum throttle position.
- After a few seconds, the motor will make 2 short beeps followed by 2 longer beeps to confirm that the throttle Range Calibration has been complete.
- Power off the ESC.
- The throttle range calibration is complete, and you're good to use the ESC as usual.

Normal Start up Procedure - Written Instructions
- Put the transmitter's throttle in the minimum throttle position, power on the ESC.
- Plug in the ESC
- If the throttle is partially on, the ESC goes into its Safe Start Protection mode and continually makes rapid short beeps until the throttle is put in the minimum throttle position. See ESC Features and Protections for more information.
- If the throttle is in the full throttle position, the ESC enters into its programming mode and makes several different tones. If this is the case, re-power the ESC with the throttle in the minimum throttle position. See How to Change the ESC's Settings (Programming) for more information.
- The ESC makes a series of short beeps.
- The first set of beeps indicates the number of cells the ESC detects in the battery. E.g., 3 beeps indicate a 3 cell battery. (You can change the ESCs battery-type setting if needed. The default is LiPo. See Programming Instructions for more information).
- The second set of beeps indicates the brake setting. Single beep if the brake is on or a double deep if the brake is off.
- The ESC is ready to be used.
How to Change the ESC's Settings (Programming) |
|
The CLASSIC ESC series are plug-and-play and do not need to be programmed to work. The ESC settings can be changed using two different methods. Method A uses the transmitter, or Method B uses an RCElectricParts.com's Programming Card (Sold Separately). Both ways work. Using the transmitter might seem complicated, but it isn't hard once you've done it. Using a programming card is more straightforward but requires buying a separate unit. I still prefer using the transmitter method.
Method A: Changing ESC Settings Using the Transmitter

*See the table of programmable settings below
Changing ESC Settings Using the Transmitter - Written Instructions
There are five different tones symbolized by a letter, A, B, C, and D. Once the ESC goes into its programming mode, it consecutively goes through the programmable settings, starting with setting #1 and ending on setting #22. To cycle through the settings again, re-power the ESC. To determine which setting is currently selected, listen to the tone sequence. WHILE the ESC is on the desired setting, move the throttle to the minimum position to activate that setting. Poweroff the ESC and follow the Normal Start Up Procedure.

Factory default settings are as follows:
9 - 11. Timing: Automatic, Low, High
9. Automatic: The ESC automatically detects the most suitable motor timing.
10. Low (7 – 22 degrees): Suitable for most inrunner motors.
11. High (22 – 30 degrees): Suitable for most outrunner motors.
*Note: We recommend using "Automatic" timing. Efficiency can be increased for 2 pole inrunner motors by settings the timing to low and for 6 pole outrunner motors by setting the timing to high. Power can sometimes be increased for outrunner motors by setting the timing to high at the cost of efficiency and excess motor heat.

12 - 14. Motor Start up Speed: Very Smooth, Smooth, Accelerated Start up
12. Very Smooth: 1.5-second linear throttle lag response time between starting the motor and full motor speed. This setting is excellent for preventing gearboxes from stripping from starting up too fast.
13. Smooth: 1-second linear throttle lag response time between starting the motor and full motor speed. This setting is recommended for geared motors or slower start ups.
14. Accelerated: 0-second throttle lag response time between starting the motor and full motor speed. This setting is recommended for direct-drive motors and responsive throttle control.

14. Accelerated: 0-second throttle lag response time between starting the motor and full motor speed. This setting is recommended for direct-drive motors and responsive throttle control.
15 - 17. Helicopter Modes: Off, Mode 1, Mode 2
15. Off: Turns off Helicopter Mode.
16. Helicopter Mode 1: Delays throttle response time between zero-throttle position and full-throttle position by 5 seconds.
17. Helicopter Mode 2: Delays throttle response time between zero-throttle position and full-throttle position by 15 seconds.
*Note: Helicopter Mode is slightly different than "start up speed" as it only delays the throttle lag response time when the throttle is in the zero-throttle position for a few seconds and then when the throttle is applied. Otherwise, the throttle will respond according to the programmed "start up speed" parameter.
**Note: If the Helicopter Mode is turned on, the Brake setting will be reset to "Off", and the Low Voltage Protection Method setting will be reset to "Reduce Power".
15. Off: Turns off Helicopter Mode.
16. Helicopter Mode 1: Delays throttle response time between zero-throttle position and full-throttle position by 5 seconds.
17. Helicopter Mode 2: Delays throttle response time between zero-throttle position and full-throttle position by 15 seconds.

18. Motor Rotation Direction: Forward, Reverse
18. Forward OR Reverse: Changes the motor direction to be either forward OR reverse. Not forward AND reverse as that requires a bi-directional ESC and the CLASSIC ESC series are uni-directional ESCs.
*Note: The motor's rotation direction can also be reversed by swapping any two of the three connections between the motor and ESC. The Motor Rotation Direction setting is helpful if the connection between the motor and ESC is hard to get to or soldered.

19 - 20. PWM Frequency: 8kHz, 16kHz
19. 8kHz: Output Frequency to the motor. Generally used for inrunner motors with lower pole counts, more power-efficient, causes less Electromagnetic Interference (EMI), and is the ESC's default setting.
20. 16kHz: Output Frequency to the motor. PWM frequency is generally used for outrunner motors because the motor will run smoother and with slightly more power but at the cost of the ESC running hotter causing more Electromagnetic Interference (EMI).

ESC Safety Features & Protections |
|
Start up Protection
The ESC will stop the motor if the motor fails to spin within two seconds after applying the throttle. Possible situations that would cause this fault are: The motor or propeller cannot freely rotate, a connection between the motor and ESC, or an electrical short in the motor.
Safe Start Protection
If the throttle is applied before the ESC is powered on, the ESC will not power the motor and will beep rapidly until the throttle is put in the minimum throttle position. Then the ESC will go through its start up procedure as usual. This is to prevent the motor from unexpectedly starting up when powering on the ESC
Overheat Protection
If the ESC gets hotter than 212 °F (100 ℃), the ESC will limit the output power to 40% to prevent the ESC from becoming damaged without shutting off all power output during operation. Once the ESC's temperature reaches operating temperature, the ESC will work as usual.
Signal Protection
If the receiver losses signal for more than two continuous seconds, the ESC will reduce power. If the lost signal continues for more than four seconds, the ESC will gradually shut off power to the motor, preventing a runaway object.
Low Voltage Protection
The warning tone: The warning tone is set as an audible sound to help users judge abnormal conditions after turning on the power. 1. Fail to enter working mode after turning on the power: the routine of the throttle has not been set yet. 2. Continuing beeps: the pull rod of the throttle is not in the lowest position. 3. There is a short pause after a beep: the ESC can not detect normal throttle signals from the receiver. 4. There is a pause of one second after a beep: the voltage of the battery pack is out of acceptable limit (once the battery is connected, the ESC will carry out a self-checking and check the voltage of the battery.)

DO
DO NOT
- Remove the propeller from the motor when programming or using the ESC for the first time.
- Use a battery that is in good condition and rated above the maximum current draw of the motor.
- Use a battery that is within the cell/voltage range of the ESC.
- If using new connectors, make sure the battery polarities are correct. Reversing the polarity will destroy the ESC. I.e., red (+) to red (+) and black (-) to black (-).
- Install ESC with good ventilation so heat can dissipate.
DO NOT
- Do not overload the SBEC by using too many or too big servos and other components. Drawing too many amps will cause the SBEC voltage to drop (brownout) and may cause the receiver to reboot during use.
- Do not get the ESC wet.
- Do not unplug the battery while the motor is spinning.
FAQs |
|
Q: Does this work with brushed motors?
A: No, this ESC is designed specifically for brushless motors
Q: The motor makes a rapid succession of beeps on start up.
A: The ESC has entered into its start up protection mode to prevent the motor for unexpectedly rotating and the ESC is rapidly beeping to let you know the throttle is part way on. Once the throttle is put into the minimum throttle position, the ESC will make the start up confirmation beeps and will work as normal.
If putting the throttle in the minimum throttle position doesn't fix the issue, you'll need to do a "Throttle Range Calibration". See First-time Use
Q: Can the ESC run in forward and reverse?
A: The ESC is a uni-directional ESC designed to run the motor only in one direction during operation. The ESC has a programmable setting to reverse the motor direction, so you do not have to swap any two of the three motor wires to reverse the motor direction manually.
Q: The motor spins in wrong direction. How do I reverse the motor direction?
A: There are two option. Swap any two of the three motor plugs or, if it is easier, program the ESC to run in the opposite direction. See programming instructions above.
