The Hobbywing QuicRun WP 10BL120 G2 ESC builds on the previous generation controller and adds the most asked for features from users! The IP-67 Ingress Protection Rating guarantees excellent waterproof and dustproof protection. This allows the ESC to be used in challenging environments including those with mud, sand, ice, snow, and water without damaging the unit. The innovative intelligent freewheeling technology enables higher driving efficiency and lowers the operating temperature of the ESC. The powerful built-in BEC is able to provide a stable continuous current of 5 Amps, and a peak current of 10 Amps. Combined with the adjustable output voltage of 6 Volts or 7.4 Volts, the BEC is capable to run today's demanding digital servos without an external power source. All of the energy flowing through the system builds up heat. The integrated radiator design combined with the patented copper thermal conduction heat sink on the internal power board of the ESC provides excellent heat dissipation. The added fan ensures you can keep running even when the ambient temperatures climb high. Special attention has been paid on the built-in capacitors. By using high capacity 1640uF capacitors and built in thermal protection, you get piece of mind as well as easy setup when adding the ESC to your favorite RC platform.
