Hobbywing EzRun Max8 G2 4278SD & 2250Kv Brushless Motor and 160Amp ESC Combo HW38010405


Hobbywing EzRun Max8 G2 4278SD & 2250Kv Brushless Motor and ESC Combo


This combo contains a built-in chip that works perfectly with the Hobbywing EZRUN MAX8 G2 esc, creating a pure and full sensor mode power system. This means you will get better performance and smoother control. The rotor has four strong and heat-resistant magnets that provide super torque and explosive power. The encoder outputs a pure and stable sensor signal, avoiding any interference. The motor also has high output efficiency, which reduces the temperature and increases the power. The motor is made of high-quality materials, such as CNC machined aluminium, high-purity copper, stainless steel, and silicon steel. It also has a new sensor interface and rubber cover bearing that are more waterproof and dustproof than traditional ones. This motor is a great choice for any RC car enthusiast! Order yours today and enjoy the speed and thrill of this sensored motor.


32 Degree Turbo Timing Setting
      : When used with the matching motor (such as EZRUN 4278SD), the maximum rpm can be increased by about 25%, easily win your rival.
 * Requires OTA Programming Card (sold separately)
  • The ESC uses a special process, coupled with an innovative waterproof design, to increase waterproofing and dust-proofing performance in different climates. It is easy to deal with the harsh conditions containing sediment, ice, snow, and water accumulation
  • Built-in ultra-powerful switch mode BEC with a continuous current of 6A, an instant 15A, and support for 6V/7.4V/8.4V switching, supporting a wide range of powerful and high-voltage servos
  • Equipped with the most advanced and safe electronic switches. The traditional mechanical switch protects and prevents dust, humid and other harsh environments, contact rust, and violent impact (such as flying slope landing) caused by the automatic closure of mechanical switches and other issues
  • Multiple protection functions: battery low voltage protection, ESC and motor overheat protection, signal loss protection, and current protection
  • Support LED program card, LCD G2 program box, OTA programmer (Note: optional) to set the parameters of the ESC.
  • Real-time data logging to view various running data on the HW LINK app using the OTA Bluetooth module
  • Support the firmware upgrade of the ESC (The multi-function LCD G2 program box or OTA Programmer is needed to purchase), you can enjoy the latest functions
