     ⚫ Getting Started with Setup

      I will explain the parameter settings for the 12S LiPo ESC (SEQURE 14130) in detail. The screen above shows the connection via the "SEQURE ESCape32 WiFi-link" board (a chip board about the size of a thumb joint, costing a few thousand won on AliExpress). You need to connect this board to the ESC signal line along with a power supply (5–35V), and the ESC must be powered on during this process (a 12S battery is not strictly required for this step). Once connected, "" will appear on the Wi-Fi selection screen of your smartphone or computer. Click it, type the IP address https://192.168.4.1 into your web browser, and hit enter to bring up the screen shown above.

SEQURE 14130 ESC MCU SETUP

     ⚫ ESC BEC

      This ESC was originally released for RC crawlers and drones. I chose it because it is affordable and had decent user reviews. A standard commercial ESC suitable for an HF700 530KV (700-class) helicopter motor—such as the HobbyWing Platinum series—costs hundreds of thousands of won. However, this ESC is less than a third of that price. Despite the low cost, its performance does not fall short. I am currently using it without any issues and am highly satisfied with its performance. The only catch is that it lacks a built-in BEC (Battery Eliminator Circuit). While some users might consider this a drawback, I personally prefer setting up a separate dedicated BEC anyway, as I am always concerned about electromagnetic interference (EMI) on 550-class or larger models. Manufacturing an all-in-one ESC with an integrated BEC requires additional components, such as shielding to prevent internal interference, which drives the price of brand-name ESCs through the roof. For someone like me who enjoys this purely as a hobby rather than competing in tournaments, those prices are incredibly burdensome.

       A unique feature of this ESC is that it is released in three different versions depending on the firmware flashed onto the MCU (Microcontroller Unit): AM32, ESCape32, and BLHeli32(BL32 PR). You can reflash and change the firmware depending on your personal preference or application. These open-source firmwares are publicly available, and you can download the latest updates for free. Although they are fundamentally designed for crawlers and drones, this ESC offers excellent cost-to-performance value for a 700-class helicopter, provided you configure the parameters correctly for helicopter use. I chose the version pre-flashed with the ESCape32 firmware because documentation suggested it has a slight advantage when optimizing for helicopters. For reference, despite having "Heli" in its name, BLHeli32 is not explicitly a helicopter-specific firmware either. Adapting an ESC developed for crawlers and drones to work on a helicopter is quite a challenge. Since it is a relatively new product on the market, the user base isn't massive yet, though word-of-mouth is positive and the community is steadily growing. The main hurdle is that you have to figure out the specific setup know-how through your own trial and error.

     ⚫ ESC Parameters

Now, let's go over the parameters one by one. The box on the left of the main screen allows you to configure settings and change the ESC startup music (startup tones). The next section is used for flashing or changing the firmware on the ESC's MCU. The bottom-left area displays the status and specifications of the active connection. Once you finish configuring your settings, clicking <Save> will cause a green, blinking <Done!!> message to appear. The horizontal slider below that allows you to test and verify your settings with the connected motor. Moving the slider to the right with your mouse makes the motor spin according to the configured values. Before doing this, you must "Arm" the system. Arming essentially readies the motor; by dragging the cursor all the way to the left and then to the right, a beep will sound, and the motor will become active. The specific parameter tuning details are covered in Part 2. ■■■
