This is the Castle Creations QuadPack 35 Multi-Rotor 35-Amp ESC Set. This pack of four 35-amp Castle Creations multi-rotor ESCs is equipped with three ESC's without a BEC and one with a BEC (The single BEC supplies power for all 4 controllers). Each ESC has optimized firmware specifically designed for quadcopter and other multi-rotor platforms. Refresh rates up to 490 Hz give your platform optimum stability and maneuverability without missing a beat. QuadPack 35 comes pre-programmed for multi-rotor platforms and is recommended for platforms ranging from 450 to 650 sizes pulling up to 35 amps** and running up to 6S LiPo. As with all Castle ESCs, this product is easily programmable using the Castle Link USB adapter (sold separately).

**NOTE: RC HOBBY APPLICATION RATING: 35 amps for the duration of a single 4,000 mAh battery pack with the ESC's in contact with a 5 mph airflow of 25C (77F) or cooler air. Controller temperature must never exceed 100C (212F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESCís operating temperature.
