Hobbywing EZRun 1/6th Sl 4985-1250Kv Motor (Black)

The Hobbywing EZRun 4985-1250Kv (Part No: HW30402951) is a massive, high-torque sensorless brushless motor designed for heavy-duty 1/6 and 1/7 scale vehicles. Sitting as a "bridge" between standard 1/8 scale power and full-scale 1/5 scale systems, the 4985 size is specifically optimized for vehicles like the Arrma Kraton 8S, Outcast 8S, and Traxxas X-Maxx. With its 4-pole rotor and 1250Kv rating, it is built to deliver "wheelie-popping" torque and rock-solid stability even when pushing 8S LiPo power.

Key Features:

• 4-Pole High-Torque Rotor: Features a strong internal structure that handles instant full-torque start-ups and aggressive acceleration without the risk of "throwing" a magnet.
• High Efficiency: Utilizes Hobbywing's temperature control technology to achieve up to 90% efficiency, meaning less energy is wasted as heat and more is sent to the wheels for longer run times.
• CNC Machined Construction: Encased in a hard-anodized aluminum housing with 0.2mm silicon steel laminations and high-purity oxygen-free copper windings.
• Built-in Thermal Protection: When paired with the EZRUN MAX6 or MAX5 ESC, the motor's internal sensor allows for real-time temperature monitoring to prevent overheat damage.
• 6.5mm Gold Connectors: Comes pre-soldered with heavy-duty 6.5mm male bullet connectors to handle the high current flow required for large-scale bashing.

Gearing & Mounting Tip:

The 4985-1250Kv motor is unique because it combines a large 1/6 scale can size with a 5mm output shaft. This allows you to use standard 1/8 scale pinions (MOD1), which is helpful for many Arrma and Traxxas conversions. However, because of the massive torque this motor produces, ensure your motor mount is reinforced; the extra weight and rotational force can flex plastic mounts, leading to stripped gears. For the ultimate 8S setup, pair this with an EZRUN MAX6 ESC.
