Overview
Hobbywing QuicRun 2840SL 4700KV G2 is a sensorless brushless motor for 1/14th and 1/16th scale vehicles. It is designed to pair with the HOBBYWING QuicRun WP 12BL45 G2 ESC and supports 2S LiPo.
Key Features
- High efficiency, low power consumption, low temperature rise.
- Maximum efficiency up to 80% (2850-3400KV motor used as an example for the series).
- Under the same load conditions: lower operating temperature, more stable continuous output, consistently maintains optimal performance.
- IP56 protection rating for dust resistance and reliable performance in wet conditions.
- Silicone wire output design for more flexible and cleaner wire routing, making installation easier.
- Pre-soldered, gold-plated 3.5mm connectors for plug-and-play installation.
- Selected 0.2mm thick silicon steel laminations, high-temperature resistant enameled wire, and premium high-precision bearings for durability.
