Multistar 20 Amp Multi-rotor Brushless ESC 2-4S

MultiStar ESCs are are a quality speed controller at a fantastic price! Designed for simple installation and easy setup these ESCs have proven to offer excellent performance when used in Multi-rotor applications. If your starting out in Multi-rotors and need an easy to install solution that is tested and proven to work with Multi-rotor craft then these speed controllers have you covered.
These ESC's features a very smooth yet linear throttle response, without sacrificing a rapid, crisp, response to any throttle input. Safety is not forgotten with all Multistar Esc's featuring adjustable battery LVC (set battery type to LiXX to disable LVC), stalled motor (overload) protection, signal loss shut-down and safe arming.
All Multistar series ESC's come with bullet connectors installed that are suited to the ESC's rated power handling.

This allows for plug and play convenience by simply adding the appropriate battery supply splitter (3,4 or 6 ESC) and motor lead extensions from the Multistar modular accessory line. What could be simpler?
All Multistar ESC's feature an ATmega MCU that opens the door to customizable firmware - for those so inclined! or alternatively a programming card can be used with the installed software for quick and easy setup with the pre-flashed software.
