HobbyKing 30A BlueSeries Brushless Speed Controller

Built with imported N-Channel mosFETs and an ultra fast Atmel MCU & heartbeat make this a high performance ESC with excellent sync capabilities.
This ESC has a 3A BEC for solid reliable servo power.
Programmable via an R/C controller.It allows you to program all functions to fit your specific needs,
which makes it efficient and user friendly.

Features:
Extremely low internal resistance
Super smooth and accurate throttle linearity
Over heat and over-load protection
Auto shut down when signal is lost or radio interference becomes severe for more than 2 seconds
Supports high RPM motors
Power arming protection (prevents the motor from accidentally running when switched ON)
New Advanced programming software
