      1. Running Mode
      • Option 1: Forward with Brake
        • The vehicle can go forward and brake but cannot reverse in this mode. This mode is usually for racing.
      • Option 2: Forward / Reverse with Brake
        • This mode provides the braking function, it’s usually for training. “Forward/ Reverse with Brake” mode adopted the “DOUBLE-CLICK” method, that is your vehicle only brakes (won’t reverse) when the 1st time you push the throttle trigger forward (away from you) (1st push). If the motor stops when you quickly release the throttle trigger and then re-push the trigger quickly (2nd push), the vehicle will reverse. If the motor does not stop, then your vehicle won’ t reverse but brake, and you need to push the throttle trigger one more time. The vehicle only reverses after the motor stops. This method is for preventing vehicle from being accidentally reversed.

      2. LiPo Cells

      We strongly recommend setting this item manually instead of using the default setting “Auto Calc. (which means calculating the LiPo cells automatically)”. The ESC can only identify 3S, 4S

      and 6S LiPo packs when setting this item to “Auto Calc.”. After you power on the ESC, if the battery voltage is below 13.6V, it will be identified as a 3S, if the voltage is from 13.6V to

      17.6V, it will be identified as a 4S, if the voltage is above 17.6V, it will be identified as a 6S.

      Note 2:

      • This ESC is not intended for 2S operation. Even if you can set the “LiPo Cells” to 2S, it still does not work.
      • You need to set “LiPo Cells” to “Auto Calc.” and “Cutoff Voltage” to “Disabled” if you use a NiMH pack or a 5S LiPo.

      3. Low-Voltage Cutoff

      Sets the voltage at which the ESC lowers or removes power to the motor in order to either keep the battery at a safe minimum voltage (for Lipo batteries). The ESC will monitor the battery

      voltage all the time, it will immediately reduce the power to 50% and cut off the output 10 seconds later when the voltage goes below the cutoff threshold. The RED LED will flash a short,

      single flash that repeats (☆, ☆, ☆) to indicate the low-voltage cutoff protection is activated. If you use a NiMH pack, then please set the “Cutoff Voltage” to “Disabled”.

      • Option 1: Disabled
        • The ESC won’t cut off the power due to low voltage after you select this option. We do not recommend using this option when you use any LiPo pack (5S LiPo is an exception), otherwise you will irreversibly damage it. However, for avoiding losing power in racing due to low voltage, we recommend using this option (this still may cause damage to your battery). You need to select this option when you use a NiMH pack.
      • Option 2: Auto (Low)
        • Low cutoff voltage, not very easy to get the LVC Protection activated, is applicable to batteries with poor discharge capability.
      • Option 3: Auto (Intermediate)
        • Medium cutoff voltage, prone to getting the LVC Protection activated, is applicable to batteries with ordinary discharge capability.
      • Option 4: Auto (High)
        • High cutoff voltage, very prone to getting the LVC Protection activated, is applicable to packs with great discharge capability.

      Warning: If you set the Cutoff Voltage to Disabled when you use a LiPo pack, then please pay attention to the power change of your vehicle. In general, the battery voltage gets very low level when your vehicle is severely losing power, then you should stop using that pack.

      4. ESC Thermal (Shutdown) Protection/Overheat Protection

      The ESC will automatically cut off the output and the GREEN LED will flash a short, single flash that repeats (☆, ☆, ☆) when the temperature gets up to the value you preset and activates the ESC thermal protection. The output won’t resume until the temperature gets down.

      5. Motor Thermal (Shutdown) Protection/Overheat Protection

      This item has been permanently set to “Disabled” by the manufacturer.

      6. Motor Rotation

      Pull the throttle trigger with the motor shaft facing you, the motor spins counterclockwise if this item is set to CCW; the motor spins clockwise if set to CW. The (A/B/C) wiring order of motors from different manufacturers may vary, so the direction of the motor rotation may be opposite to what you expect. You can adjust the “Motor Rotation” or swap any two (ESC-to-motor) wires if the motor runs in reverse.

      7. BEC Voltage:
      • Option 1:6.0V
        • It’s applicable to ordinary servos. Do not use this option with high voltage servos; otherwise your servos may not function normally due to insufficient voltage.
      • Option 2:7.2V
        • It’s applicable to high voltage servos. Do not use this option with ordinary servos; otherwise your servos may be burnt due to high voltage.
      8. Max. Brake Force

      This ESC provides the proportional braking function; the braking effect is decided by the position of the throttle trigger. It sets what percentage of available braking power is applied with full brake. Large amount will shorten the braking time but it may damage your pinion and spur. Please select the most suitable brake amount as per your car condition and your preference.

      9. Max. Reverse Force

      Different reverse amount will bring different reversing speed. For the safety of your vehicle, we recommend using a low amount.

      10. Start Mode (Punch)

      You can choose the punch from level 1 (very soft) to level 5 (very aggressive) as per the track, tires, grip, your preference and etc. This feature is very useful for preventing tires from slipping during the starting-up pr ocess. In addition, “level 4” and “level 5” have strict r equirement on battery’s discharge capability. It may affect the starting-up if the battery discharges poorly and cannot provide large current in a short time. The car stutters or suddenly loses power in the starting-up process indicating the battery’s discharge capability is not good, then you need to reduce the punch or increase the FDR (Final Drive Ratio).

      11. Drag Brake

      Drag brake is the braking power produced when releasing the throttle trigger to neutral zone. This is to simulate the slight braking effect of a neutral brushed motor while coasting. (Attention! Drag brake will consume excess power, frequent use of accel and brake may damage the ESC.  Please apply it cautiously.)

      Additional Note

      1. Motor Wiring
      There is no polarity on the A/B/C wires between ESC and motor, so do not worry about how you connect them initially. You may find it necessary to swap two wires if the motor runs in

      2.Receiver Wiring
      Plug the throttle control cable (also called Rx cable) on the ESC into the throttle (TH) channel on receiver. The red wire in the throttle control cable will output the BEC voltage of 6V/7.4V
      to the receiver and servo, so please do not connect any additional battery to the receiver. Otherwise, your ESC may be damaged.

      3.External Capacitor Module (also called Cappack )Wiring (Optional)
      When using a 6S, if the capacitor temperature often goes above 85℃, you need to connect an external cappack (item sold separately) to the ESC, otherwise, the insufficient capability of
      the on-board/built-in cappack may cause capacitors to swell or even explode and the ESC to work abnormally or even get damaged. Based on our test results, an external cappack is
      needed by the following two types of vehicles.
      External Cappack Wiring Diagram (as shown above). Connect a cappack to the ESC input end and ensure red/positive (+) to red/positive (+), black/negative (-) to black/negative (-).

      A. The vehicle weighs really heavy, the total weight (battery, ESC, motor, steering servo and etc. included) exceeds 7KG, for example, CEG-GST.
      B. The vehicle weighs not heavy, but the chassis is specially designed for running a super-high speed (over 100KM/H) like Traxxas XO-1.
      Note 2: For the above two kinds of vehicles, we strongly recommend using our EZRUN MAX6 instead, because the MAX 6 has greater power output than MAX8.

      4.Battery Wiring
      Proper polarity is essential here! Make absolutely sure positive (+) of ESC connects to positive (+) of battery, and negative (-) of ESC connects to negative (-) of battery when you plug in your battery! If reverse polarity is applied to your ESC from the battery, it will damage the ESC. This will not be covered under warranty!
