ARNING: Read the ENTIRE instruction manual to W become familiar with the features of the product before operating. Failure to operate the product correctly can result in damage to the product, personal property and cause serious injury. This is a sophisticated hobby product. It must be operated with caution and common sense and requires some basic mechanical ability. Failure to operate this Product in a safe and responsible manner could result in injury or damage to the product or other property.
SKU Current (Continuous/ Burst) Voltage BEC ONXM4020 40A/60A 3 – 6S LiPo 8A 5.2V/6V/7.
Connection and Installation Mount the ESC so it cannot move around inside the aircraft and in a location where it can receive free-flowing air during operation. It is normal for the ESC to get warm while in operation.
Throttle Range Calibration When you first install the ESC, you will need to calibrate the throttle range. WARNING: Remove the propeller from the aircraft for safety during setup. Removing the propeller from the motor enables the operation to be tested safely. WARNING: For some radio control systems (Futaba and Tactic in particular), you will need to reverse the throttle channel for normal operation where OFF is with the stick at the low position.
Motor Reversing (Optional) CAUTION: For safety, always assume the propeller could spin any time the battery is plugged in. If you wish to use the motor reverse function, connect the Aux input cable from the ESC to an open channel on your receiver. You will need to select Reverse in the Brake Type settings to use this function, it is disabled by default.
Stick Programming CAUTION: For safety, always assume the propeller could spin any time the battery is plugged in. IMPORTANT: Complete throttle calibration before attempting stick programming. Power on your transmitter with the throttle at the full position. Connect the battery to the ESC. TIP: If a selection is not made the ESC will return to the beginning of the list and cycle through the options again. TIP: There are twelve programming parameters. See the table below for full details.
After making a selection the ESC will continue down the list of parameters. To make a selection, move the throttle stick to the full throttle position. After exiting programing and with the throttle at the low position, the ESC will arm and operate normally. Programming Parameters Programming Number of Tones Parameter Select the last parameter (#13) to save the settings and exit programming.

Programming Options Descriptions 1. Brake Type: The throttle range changes depending on the Brake Mode Signal position as shown on 100% -100% Spektrum transmitters -60% 60% 0% 0% 20% 50% Throttle signal (pulse position) 80% 100% Normal Brake The motor brake will activate when the throttle stick is moved to the low position. In this mode the strength of the braking is set with the Brake Force selection.
Proportional Brake With this option selected, the throttle range changes so the ESC will not start below 20%. The throttle will operate as normal above 20%, but moving the throttle below 20% will apply the brakes, increasing in strength as the signal drops to 0%. Throttle and Brake Response 100% Brake 100% Throttle 0% Brake Throttle/Brake Range Throttle Signal 0% 20% (-60% as shown on Spektrum transmitter screens) Reverse Brake 100% Select this option if you want to enable reverse.
4. LiPo Cells Select Auto Calc to cause the ESC to automatically calculate the number of LiPo cells based on a 3.7V/cell default. Alternatively, you can select a specific sell count to set the ESC to a fixed battery configuration. 5. Cutoff Voltage Use this option to adjust the cutoff voltage from 2.8V to 3.8V/cell or disable the cutoff voltage completely. WARNING: Discharging a LiPo battery below 2.8V/ cell may damage the battery. Attempting to charge or discharge a damaged battery will cause a fire. 6.
Programming with the DYNS3005 Programmer Box 1. Begin with the ESC powered off. 2. Connect the programming lead to the programming port on the programming box. 3. Connect a battery to the ESC. 4. Power on the box and select the parameter with the SELECT button. 5. Change the values of the selected parameter with the EDIT button. 6. Press the SAVE button to save the changes. Failsafe Protections Start-up Protection: The ESC will monitor the motor speed during the startup process.
Throttle Signal Loss Protection: When the ESC detects loss of signal for over 0.25 second, it will cut off power to the motor immediately. The ESC will resume normal operation when throttle signals are received. Overload Protection: The ESC will cut off power to the motor if there is a sudden load that exceeds predetermined limits. Over-current Protection: The ESC will cut off power to the motor if the peak current goes above the rated value.
Troubleshooting Guide Problem ESC Tones Possible Causes Input voltage Two short is beyond the tones operating range repeating of the ESC Motor won’t operate and continues to emit tones 16 Solution Ensure the operating voltage is within the specs for the ESC Verify the transmitter and receiver are connected, check the throttle lead is in the correct servo port, and check channel assignments The throttle Move the throttle control to the low One short input is not at the low position position tone repeat
Motor stutters during operation above 60% throttle and continues to emit tones at low throttle Motor output is suddenly limited to 60% power during operation and continues to emit tones at low throttle Two short tones repeating after operation The ESC has gone over the temperature limit and activated the thermal protection feature Three The voltage of short the battery has tones dropped too repeating low and the after LVC feature has operation been activated.
